Mathematical had been invented early in ancient Egypt, Mesopotamia and ancient India. Until today, development of mathematics still ongoing. Mathematics has become our indispensable part of daily life. Besides that, mathematics has been incorporated into the field of education. Today mathematics has been widely used in various fields such as science, medicine, engineering and business. Leonardo Da Vinci was an Italian polymath. His field of interest included invention, painting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, writing, history, and so on. He was well-known as a painter. Mona Lisa is one of his famous works. However, he also a famous mathematician in the world. He has a great contributions for the history of mathematic. Leonardo da Vinci thought that mathematics was an essential tool for painting. He had explored the laws of geometric between hexahedron, cylinder, and sphere area. He was the first person using the symbol of plus (+) and minus (-) in mathematics. Grace Hopper was a representative of a modern mathematician. She had great contributions on mathematics because mathematics was her favourite subject since childhood. She obtained her master’s degree in mathematics in 1930 and received her PhD in 1934. Her doctoral thesis was “A new Criterion for Reducibility of Algebraic Equations”. She was one of the first female programmers of computer. She had invented first high-level programming languages – COBOL. She fostered many programming language specialist, have a name called “Amazing Grace”. These mathematicians has a great contributions for human progress. Their contribution let us have a convenience life, and it has been widely used in life. We must cherish to their contributions.

...Simple interest is the interest that is computed on the original principal only. If I denotes the interest on a principal P (in dollars) at an interest rate of r per year for t years, then we have I = Prt The accumulated amount A, the sum of the principal and interest after t years is given by and is a linear function of t. A= P + I = P + Prt = P(1 + rt) A bank pays simple interest at the rate of 8% per year for certain deposits. a. If a customer deposits $1000 and makes no withdrawals for 3 years, what is the total amount on deposit at the end of three years? P = 1000, r = 0.08, and t = 3 A=P(I+rt)=1000[1+(0.08)(3)]=1240 or $1240 b. What is the interest earned in that period? I=Prt=1000(0.08)(3)=240 or $240. Compound interest Frequently, interest earned is periodically added to the principal and thereafter earns interest itself at the same rate. This is called compound interest. Suppose $1000 (the principal) is deposited in a bank for a term of 3 years, earning interest at the rate of 8% per year compounded annually. Using the simple interest formula we see that the accumulated amount A1 = P (1+rt) =1000[1+0.08(1)] =1080 These observations suggest the following general rule: If P dollars are invested over a term of t years earning interest at the rate of r per year compounded annually, then the accumulated amount is This formula is derived under the assumption that interest was compounded annually. In practice, however, interest is usually compounded more...

...The task of this assignment was to do some research, gather information and process the information to better understand a product. In this week we decided to look at our local pizza spots and see how good the deals really are. I chose two locations that I eat at on a regular basis and I was very surprised at what I discovered. In order to set a baseline for this project I chose to stick to the Small, Medium and Large Pizza deals. These prices are all based on a one topping peperoni pizza. In both cases though the prices were different, the extra toppings were both $.75 apiece. Since this was a constant variable for both locations, I decided it wasn’t that necessary to include. The two locations I decided to use were “I Love NY Pizza” and “2 Guys Pizza.” Both of these places have excellent pizza and it’s more of a convenience when I am deciding where I eat. With this new information though, I might be sticking to one location for now on though. Here are the results of my research: With this Data I am able to see that the Medium pizzas are comparable between the two places. The biggest difference in price would be in the small and large pizzas. When you factor in not only price, but also what you are getting for that price, I would have to say 2 Guys Pizza takes the win. They offer a great price of only $.01 a sq. in and the pizza itself is 300 sq. in larger than I love NY Pizza. When you look at this project as a whole there are a lot of variables that weren’t taken into...
