Four Geometry Formulas Essay -- Geometry

As you begin the course of geometry students are generally familiarized with frequently used formulas in mathematics. These formulas include finding the perimeter and area of two-dimensional figures and finding the volume and surface area of three-dimensional figures. For every diverse shape there is a related formula for finding its perimeter, area, volume, or surface area. Therefore, we will only focus on four formulas for four singular shapes or figures. We will find the perimeter of a square, the area of a triangle, the volume of a right circular cylinder and the total surface area of a sphere. The first formula will correspond to finding the perimeter of a square. For the following formula P will stand for the perimeter and s will represent the side length of the square. The perimeter of a square is found by multiplying four by the side length of the square. Thus, the formula would be P=4s. The motive that the four is in the formula is because a square has four sides. Now let’s use an example, if a square has a side length of 4 inches on every of its four sides the formul...

Pros and Cons of the Scholastic Aptitude Test

Why I chose this topic: Should the SAT be used for college admissions? The SAT has been a huge controversy for a long time, however, it wasn’t until several months after getting into college that I began to really question why it’s used for admission. The only answers I really got from the college board was that it is â€Å"designed to assess your academic readiness for college and provides a path to opportunities, financial support and scholarships, in a way that's fair to all students. It also keeps pace with what colleges are looking for today, measuring the skills required for success in the 21st century. I still was not convinced because not all those answers seemed right to me. What is the SAT: So what is the SAT? The Scholastic Aptitude Test is a standardized test used by college admissions. It is a timed test featuring a Critical Reading, mathematics, and writing section. Pros vs Cons of the SAT: Proponents of the SAT claim that it is a great indicator to colle ges as to how students will do in college since it assesses the critical thinking skills needed. Opponents of the SAT claim that it is a poor indicator of the intelligence of the student. Why it should not be used: Why should the SAT not be used?Before even getting to the components of the test, first lets take into account the fact that a lot of people out there do not have enough money for tutors or books who really need them for preparation. A lot of other people hire tutors or get a lot of books to prepare them well and therefore the preparation itself just went through an unfair process. Secondly, the test is timed and we all work at different paces. There are those of us who can read really fast and get all the information down fast but there are those of us who cant read as fast but can still get down all the information very well.There are those of us who can quickly think about how to format an essay but there are those of us who need more time are can still write a great e ssay. Therefore, the fact that it is timed definitely factors in to not being able to truly indicate how smart the student really is. The SAT is also very culturally biased in the way that there are many people out there who come to the United States late in their school career and barely know any English and are all of a sudden expected to have a great English vocabulary and great English reading skills just to have a chance to go to college.Once again, another reason the SAT does not truly determine the intelligence of the student. Conclusion: The SAT shows how the student did on ONE test as opposed to grades, which show the student did overtime. There are many people out there who are not very good test takers and there were probably many who just did not feel themselves the day of their SAT and ended up doing worse than they were capable of. The SAT is a very biased test in a lot of aspects and should absolutely be abolished because it poorly indicates how smart the student real ly is and, in several cases, how the student can perform in college.

E. B. White’s Charlotte’s Web: A Review Essay

Introduction A friend is someone who falls somewhere between intimate love relationships and casual relationships. In a love relationship the binding force is either kinship or marriage with full sexual priveleges. Casual relationships carry no obligations with them. They are comprised of of next door neighbors or work relationships in which there is brief and superficial contact. Nothing deeply personal is revealed and there is no sense of mutual obligation. People exchange greetings and pleasantries in ways that are polite. On the other hand, friendship relationships are neither sexual nor kinship in nature. However, there is a sense of mutual obligation and friends feel deep emotional ties. More than anything friendship relationships are based on a kind of intimacy. How would you feel if you had to give up a cute little pet? What would you do if a friend’s life was in danger? How far would you go to protect someone or something you care about? Discover these answers and more when you read one of the most beloved and well known books of all time, Charlotte’s Web! This is a story about friendship, compassion, caring, and loyalty. Here you will meet Fern, a girl who lives on a farm, Wilbur a tiny, lovable, runt pig, Charlotte, a clever and wise spider, and Templeton, the hungry rat. Come and see how these characters meet and become friends and how one of them will save the life of another. Summary Charlotte’s Web is a children’s novel by American author E. B. White and  illustrated by Garth Williams; it was published in 1952 by Harper & Brothers. It features a pig named Wilbur and his spider friend Charlotte who saves him from slaughter. One morning at the breakfast table, eight year old Fern sees her father leave the house with an axe and asks her mother where he’s going. Her mother delivers the shocking news that Mr Arable is going out to kill a runt that was born the night before. Fern chases her father down and persuades him to spare the runt, telling him that it is unjust to kill a piglet just because it is small. Moved by his daughter’s plea, Mr Arable decides to give the runt to her to look after. Fern names the piglet Wilbur and looks after him like a baby, pushing him in her pram alongside her doll and feeding him with a bottle. At five weeks old Mr Arable insists that Wilbur is sold and he goes to live in the Zuckerman barn down the road . Wilbur initially struggles at the barn because he misses Fern so much but soon he becomes acquainted with new friends, the best of whom is a lady grey spider called Charlotte. Wilbur is fascinated by Charlotte, although to begin with he is slightly suspicious of the way she catches her food – he doesn’t like the idea that she spins bugs in her web and sucks their blood. He soon realizes that Charlotte is everything but cruel and bloodthirsty and that her method of eating is entirely necessary for a spider. Wilbur is complete happy during the summer days – Fern comes to visit and his new friend tells him exciting stories and has the patience to try and coach him about how to spin a web (although she knows fine well he will never be able to) but one day he gets some terrible news that puts an end to his carefree attitude. The sheep tells Wilbur that Mr Zuckerman is fattening him up for Christmas dinner and Wilbur is distraught – he is so happy on the farm and doesn’t want to die. Charlotte calms him down and promises him that she won’t let him be killed. She hasn’t worked out how to save him yet, but she is determined that she will. One morning as Lurvy pours Wilbur’s slops, he notices Charlotte’s twinkling spider web in the morning fog. The words ‘SOME PIG’ have been weaved into the web. Lurvy is gobsmacked and utters a prayer. He quickly tells Mr Zuckerman who is equally amazed and soon the news spreads near and far. Worried that people may be getting bored of ‘SOME PIG’, Charlotte asks Templeton the rat to aid her in finding more words to write in her web. Knowing that if Wilbur is killed he won’t have access to his slops,  Templeton reluctantly scavenges for newspaper clippings to help Charlotte. The next word she writes is ‘TERRIFIC’ and after that, ‘RADIANT.’ Meanwhile, Mrs Arable is concerned that Fern is spending too much time down at the barn and becomes even more alarmed when her daughter tells her about Charlotte and the stories Charlotte tells. Mrs Arable decides to go and see Dr. Dorian to ask him what he makes of Fern thinking the animals can talk and what he makes of the mysterious writing in the web. Dr Dorian is very calm and rational and says that the real miracle is not the writing in the web but the fact that a spider instinctively knows how to build a web without any tuition. He says that it is quite possible that animals can talk and that the reason that adults cannot hear them might be because they talk too much to hear what is going on in nature. With the news of Zuckerman’s famous pig spreading, the Zuckermans and Arables decide to take Wilbur to the County Fair. Charlotte agrees to go too although she is feeling tired and soon has to build a sac to hold her eggs. At the fair, Charlotte is disappointed to see that beside Wilbur’s pen is a much larger spring pig called Uncle. Knowing he is fierce competition, Charlotte decides to spin another web and once again Templeton is sent off to find a word. The adults and children enjoy themselves at the fair and Avery and Fern are particularly excited that they are allowed to go off without their parents all afternoon. Fern spends all afternoon with Henry Fussy and they go on the Ferris wheel together. For months after, Fern will look back nostalgically at her time on the Ferris wheel with Henry. Before nightfall Charlotte weaves her web with the new word ‘HUMBLE’ written into it and throughout the night she makes her egg sac. In the morning the Zuckermans and Arables see the web but they also notice that Uncle has a blue tag on his pen – he has already won first prize. Mr Zuckerman ignores the tag and tells everyone to buck up and give Wilbur a buttermilk bath. Everyone who comes to Wilbur’s pen has something good to say about him. Suddenly, over the loudspeaker a voice is heard asking Zuckerman to bring his famous pig to the judges’ booth for a special award. Wilbur is awarded a medal for being phenomenal and completely out of the ordinary and Mr Zuckerman is given $25. Since the writing first appeared in the web, the miracle has been on everyone’s mind. After the press photos and the commotion, Wilbur is returned to his pen. Wilbur notices that Charlotte is quiet and looks unwell. She tells him that  she is content now that she knows he is safe – she knows Mr Zuckerman will never harm him now, but she tells Wilbur that she is failing and will be dead in a day or two. Panicked and distraught Wilbur races around the pen, begging Charlotte to come home with him, but she hasn’t enough energy to move. Wilbur decides to take Charlotte’s egg sac and promises Templeton first choice of his slops if he retrieves the sac. As Wilbur carries the sac in his mouth and is led into the crate, he winks at Charlotte and she musters all the energy she can to wave goodbye. The next day, as the Ferris wheel is being taken apart, Charlotte dies. Back at the Zuckerman’s, Wilbur is given a noisy welcome home. He waits patiently for the birth of Charlotte’s children and often looks longingly at her empty, broken web. When her children are finally born, Wilbur is distraught to see them let out loose clouds of fine silk that carries them far away on the breeze. Three of Charlotte’s children stay in the barn with Wilbur, however and become his good friends. Year after year new spiders are born to replace the old but no one ever replaces Charlotte in Wilbur’s heart. Conclusion This book is especially good for first time readers who have taken the big jump from short stories to a real novel. It is easy reading and the talking animals captivate the young children. An affectionate, sometimes bashful pig named Wilbur befriends a clever spider named Charlotte, who lives in the rafters above his pen. A prancing, playful pig, Wilbur is devastated when he learns of the destiny that befalls all those of pork animal persuasion. Determined to save her friend, Charlotte spins a web that reads â€Å"Some Pig,† convincing the farmer and surrounding community that Wilbur is no ordinary animal and should be saved. In this story of friendship, hardship, and the passing on into time, E.B. White reminds us to open our eyes to the wonder and miracle often found in the simplest of things.

Philosophy – Design Argument (with Plan)

(b) The world appears designed, so God exists. Discuss. (30 marks) Plan: * DO NOT GO INTO ONE ABOUT GOD’S EXISTENCE!!! * Purpose and design appears to exist in nature * Mathematical formulas in nature * Gases in atmosphere * Evolution * If we were made in the image of god, then why are we such a new species and how come we didn’t exist from the beginning of time * Furthermore, why are we the only known humans on this planet and why if god was the creator has he made it so we are not suited for other planets?Let us assume that it is true to say that there is a clear existence of purpose and design in nature, the question is whether or not the existence of purpose and design implies the existence of God. The design that is apparent in the world can certainly be shown not to be the work of God, or at least God as an omnipotent (he can do anything), omniscient (he knows everything), omnipresent (He is everywhere) being. It seems that everything around us is some small cog i n a large piece of clockwork that has been intricately designed for all aspects of the planet to coincide and work with each other.The main strengths of the teleological argument are that the conditions of the world are so perfect for us to live in that it must have been designed. Evidence is everywhere. One can use the William Paley's watchmaker theory in support. Which states that: if you're walking along the beach and find a watch you don't assume it’s there by accident. You know someone must have made it due to how intricate the interior and it showing evidence of design; this is the same with the world.One of the most obvious forms of design is the Fibonacci sequence which appears in nature repeatedly; the mathematical pattern can be seen in snail shells and petals of a plant. It seems like this formula was the template for the production of nature, it surely cannot be coincidence that it appears in so many different aspects? Yet maybe it is man that has just made this t heory up and is in fact finding patterns where they do not exist, it does seem likely due to man’s attempt at rationalising everything. Hersh/Davies illustration of mathematizing the world; insert here) This is just like the Parable of the Gardener an idea where two people go on holiday and leave their garden. When they come back one of them thinks the garden has gotten overgrown and has been neglected, whereas the other sees evidence that a gardener must have been tending to it. It is an example of how people can look at the same evidence yet come to different conclusions. The parable of the gardener shows how two people can view the same thing but interpret it in completely different ways.This can be seen by contrasting the way a theist views the world and the way an evolutionary scientist views the world. The theist sees evidence of design, whereas the scientist sees evidence of evolution. It has long been demonstrated how natural selection can simulate the appearance of d esign; in short, you do not require a designer, design can be the result of a process. If we consider products such as an iPhone, we notice that the product has evolved technologically over time. Yet it most certainly had a designer.Therefore, we can see that evolution is not necessarily at odds with creation. It could be the case that the world was designed, by a designer, but has been â€Å"upgrading† through a process of evolution and natural selection ever since. The problem with this view for the theist is that the theist wants to assert that God is omni-omni-omni, and therefore would have got it right first time and would not have created an imperfect world that needs to improve itself through evolution. Yet for the agnostics this is a difficult point to comprehend as there is no proof of a god or designer.Yet as far back as the 13th century Thomas Aquinas argued that articles of faith can't be scientifically proven and that it's a mistake to try. It seems that the argu ment of the existence of god is the creation of man himself. There are some serious discrepancies between the bible and version of events known to all and the empirical evidence. According to biblical sources, man was made in god’s image on the sixth day of creation. Yet science and empirically backed sources make it clear that the existence of the human race is relatively new and was certainly not ‘formed’ at the time of the earth’s creation.The theists can argue that the bible is not meant to be taken literally, but that God still created the world, only not in six days in the way described in the biblical story. Furthermore, if humans are the ‘divine’ race then surely their existence would be found on other planets, which currently there is no evidence of whatsoever. Michael Behe came up with the Irreducible Complexity, an argument designed to counter evolution. He argues that there are things in the world (such as bacterial flagellum and t he human eye) that are so complex, they couldn’t have just arisen by chance: they must have been designed for the purpose they fulfil.Yet, the human eye is not, actually, that well designed. It is back to front for one thing! So perhaps arguments such as these are not well supported when the subject in favour is greatly flawed. Perhaps then, the Fibonacci sequence is a mere act of chance that has been evolved through natural selection as the best form of survival. However, this is too vague and does not quite explain how such a complex form of maths just ‘evolved’ repeatedly within nature.Again this is a clear indication of design and must prove that there has been planning within the planet, and on a larger scale within the universe. After all, there are solar systems which survive due to the most fragile balance of gravity, these could easily have not worked and it is of such small chances that it has. Hume often compared the universe to a vegetable, something that grows of its own accord if the environment is right; there have been examples of ‘failed’ planets just as there are sometimes failed crops.This leads onto the delicate mix of gases within earth’s atmosphere that sustain life. If any one of these gases was to change its ratio, the consequences would be catastrophic, causing the likely extinction of life within the planet. Many marvel at the slim chances that our planet is the way it is, yet they seem to forget that there have been periods of millions of years where there has been no such life due to the mix of gases being wrong, or temperatures being too extreme.However, having said this there must be design. Perhaps not in the universe as we know so little about it, but at least within the planet. It is not necessarily true that the designer is perfect, as of course there are flaws yet the sheer detail of every item in nature is so intricate that it makes one question its design and if something had a role i n creating it. Conclusion: there was a designer, but that designer was not (an omni-omni-omni) God

Detecting starch and sugars in food Essay

Aim: To detect the presence of starch and sugars (glucose and fructose) in different food sources. Background: We have many different foods in daily life and many of them contain nutrients like carbonhydrates which are essential to human life. Starch is a polysaccharide, a group of nutrients known as carbonhydrates. Glucose and fructose are monosaccharides, simpler carbonhydrates which are often refered to as sugars. In order to detect the different carbonhydrates content in ranges of food, we used two theories in our experiment. Firstly, starch can react with iodine to create a blue product. Secondly, glucose and fructose are reducing sugars which can be tested by Benedict’s reagent, because the reducing sugars which contain aldehydes group produce red copper(à ¢ ) oxide precipitate when react with Benedict’s reagent. Materials and equipments: 2cm3 of 1% starch solution, 2cm3 of 1% glucose solution, 10 cm3 of 1% iodine solution, 30 cm3 of 1% Benedict’s reagent, small amounts of different type of food (mushrooms, potatoes, bread piece, sweet potatoes, lemon, onion, biscuit, cucumber, tomatoes, peanuts,lettus, tomato sauce, dark green vegetables, milk, cereal), white tile Ten test tubes, test-tube holder, test-tube rack, Nusen burner, Heat-proof mat, safety glasses Procedures: 1. Three drops of 2cm3 of 1% starch solution was placed onto a white tile and three drops of iodine solution was added and observed the solor change. 2. 2cm3 of glucose solution was placed into a test tube and added about five frops of Benedict’s reagent and boiled gently. Observed the color change. 3. Placed small piece of ten foods in ten test tubes and added one drop of water, three drops of 2cm3 of 1% starch to them respectively and orderly. (mushrooms, potatoes, bread piece, sweet potatoes, lemon, onion, biscuit, cucumber, tomatoes, peanuts) Oserved the color change and made records. 4. Placed small pieces of ten foods into ten different test tubes and added one drops of water, five drops of Benedict’s reagent to them in order and respectively. (lemon, lettus, tomato sauce, cucumber, tomato, dark green vegetables, milk, biscuit, cereal, sweet potatoes) And boiled each test tube gently and observed the color change. 5. Made a conclusion based on results. Result 1.In procedure 1, the color of solution changed to blue-black when starch solution reacted with iodine solution. In procedure 2, the color of solution changed to orange-red when the glucose solution reacted with the Benedict’s reagent and was heated. 2.The diagram(fig.1) below shows what I observed directly after the procedure 3 : Food source Color change Mushroom Potatoes Blue-black Bread piece Blue-black Sweet potatoes Purple-blue Lemon Onion Biscuit Blue-black Cucumber Tomatoes Peanuts 3.Then,the diagram(fig.2) below shows what I observed directly after the procedure 4: Food source Color change Lemon Red-orange Lettus Dark purple-red Tomaot sauce Orange Cucumber Red-orange Tomato Orange Dark green vegetable Milk Light orange Biscuit Orange Cereal Orange Sweet potato Red-orange Analysis: 1. In my whole experiment, the procedure 1 and 2 were used as testing thoeries to give us a standard to testify whether certain food source contained certain kinds of carbonhydrates. If in procedure 3 the food turned color near blue or purple, the food must contain starch inside. What’s more, if in procedure 4 the solution in the test tube turned color near red or orange, the food msust contain reducing sugars glucose or fructose. 1. From the information and results I gathered from fig.2, I was able to figure out whether each food contains sugars glucose and fructose or not. The list was shown below(fig.4): From the diagram above we can clearly see that except dark green vegetables all the foods remained contain sugars glucose or fructose. Evaluation: During the experiment, our group made several mistakes and I listed them below to evaluate them respectively. 1. At the beginning of the experiment, during the process of adding water to the washing powder solution to 500cm3. We first ingnored the bubbles above and filled the water till the 500cm3 scale but later on we found the water was much more than 500cm3, so we repeated the experiment from the starting point once again. This time, I controled the water very carefully by pouring it softly along side the walls of the beaker and measuring cylinder to make sure there’s no bubble made during the procedures. My improvement was successful and at the second time we added water accurately to 500cm3. 2. The color of final solution in test tube â€Å"2.5mgdm-3† was as dark as that of the solution with 10mgdm-3and it’s not consistent with the general trend of other solutions. I considered the whole procedure of our experiment thoroughly and thought of two possible errors. Firstly we could have made that firstly we might add more than 5 cm3 standard detergent solution to the test tube. Secondly, because before using the 1000cm3 beaker to heat the test tube we used 500 cm3 beaker at first then we found it too small to hold six test tubes so we removed two test tubes out of the water and then put them into the bigger container. Maybe one of the two previously heated test tube was the â€Å"2.5mgdm-3† one and it’s darker because it has been heated for seconds before others.

Marketing of Guest Activities Assignment Example | Topics and Well Written Essays - 250 words

Marketing of Guest Activities - Assignment Example Guest-centric thinking is vital in marketing guest activities pertaining to a given resort. The process of marketing guest activities at the resort is one of the easiest and fun (Bowie et al.). The only requirement before undertaking this process is ensuring that there are like many of the state-of-the-art facilities at the resort as possible. The technological and scientific advances in the contemporary world has made marketing easier; where, by frequently advertising the products and services available at a given resort, one is likely to attain the targeted consumer response. Bowie et al. assert that ensuring that the guests spend most of their time at the resort would require that, as many services are made available within the environs or vicinity of the resort. Shops, parks, pools, personal amenities within rooms, laundry services, food, and beverage services, et cetera are some of the services that should be tailored to fit within the resorts. It would ensure that the guests do not need to move from place to place looking for such services, thereby spending most of t heir time within the resorts and in the process getting to spend more. External marketing would also be of importance as it would aid in attracting more clients into the resort. Coming up with the best techniques by which, to attain full marketing would be of significance. Identifying the target market and maximally utilizing the information would aid in attracting as many of the potential clients as possible. Advertising the unique and contemporary products and services would help in attracting a major client base. The use of major media outlets with consideration of the resorts capacity to utilize the same and other technological avenues would prove impactful. Using media outlets with a major client base for instance channels like Disney, would be of significance in attracting the required number of

Interest and Exchange Rates Influence on Multinational Corporations Essay

Interest and Exchange Rates Influence on Multinational Corporations - Essay Example Interest rates play an important part in investment and saving decisions. Interest rates are the main instrument of central banks to conduct their monetary policies. Interest rates have impact on foreign exchange rates. Higher relative interest rates (↑) attract higher financial investments in the short-run due to expectations for higher returns. The simplest way to explain this is to compare bank interest rates between two countries. If, in UK interest rates for deposits are 5%, compared to US deposit interest rates of 3%, then it will be economically sound for businesses to transfer their bank accounts to UK banks for higher returns. This, in turn will increase demand for UK currency, also increasing supply of US dollars. Increased demand will increase the value of the UK pound as compared to the US dollar, thus positively influencing the foreign exchange rate of the pound (↑). On the other hand, expectations for future changes also influence exchange rates. Higher interest rates (↑) have negative long-run effect on investment decisions of international businesses. Although higher interest rates attract more bank deposits, they are associated with unfavourable business situation and higher business risks for returns on investments; therefore they result in higher cost of capital (Barron’s, 1994, cited by Murphy, 1996). Since businesses worldwide are highly dependent on loan conditions, it is economically justified for businesses to invest in regions where business climate is securer, i.e. interest rates are lower.
