YANG HUI

was a [|Chinese]  [|mathematician]  if you don't know what Chinese is or what a mathematician is, no worries because I provided links :-) He is best known for his contribution of presenting ' [|Yang Hui's Triangle] '. Not much information is known about Yang Hui other than the fact that he wrote lots of outstanding mathematics. He was a contemporary of [|Qin Jiushao] and [|Li Zhi], I provided links for those guys. Yang lived towards the end of the Nan (Southern) Sung dynasty. However, Qin and Li's major works appeared about fifteen years before Yang's first work. Yang tells us that he was taught mathematics by Liu I, a native of Chung-shan, in Kwangtung province, which is south of Chekiang province where Yang Hui was born. No knowledge regarding Liu I is known. =The B A B Y L O N I A N S= Existing from about 7000 to 2500 years ago lived The Babylonians, dwelling in the area of present day Iraq between the Tigris and Euphrates rivers where the two rivers join the Persian Gulf. The climate there is hot and dry and has very little rainfall. The land in their area was a fertile oasis because of the constant water flow from the two rivers. The main concentration of the population was in and around the city of Babylon. The Babylonians were for the most part farmers; they created a complex system of irrigation between the two rivers to feed their crops. The water was strictly regulated to insure that the river resources were not wasted. Water was carried through earthen channels to the fields where it was used to water the plants. They grew mainly vegetables and grains which were transported throughout the Middle East in exchange for raw materials to make manufactured goods and textiles. Due to their complex irrigation systems and forms of plow production, Babylon was one of the most fertile areas despite it's location in the desert.

1. Suppose a farmer has 2900 yards of fencing to enclose a rectangular field. What is the largest area that the farmer can enclose? 525,625!

==2. The owner of a ranch decides to enclose a rectangular region with 470 feet of fencing. To help the fencing cover more land, he plans to use one side of his barn as part of the enclosed region. What is the maximum area the rancher can enclose? 13,806.25 ==

==3. A farmer wishes to enclose a rectangular region bordering a river using 4,000 feet of fencing. He wants to divide the region into two equal parts using some of the fence material. What is the maximum area that can be enclosed with the fencing? 652,082 == ==

==2. A ball is thrown vertically upward with an initial velocity of 48 feet per second. If the ball started from a height of 10 feet off the ground, determine the time it will take for the ball to hit the ground. 700==

My equation, x^2 - 17x + 60 + 0


To solve by graphing means: you draw a graph, then with the given equation you solve mathematically. Draw points on the graph where needed. You will form either a parabola or you may only have lines, intersecting lines. Solving by factoring means:
