Justin phase 1

Babylonians

=
they lived during the 1st Half of 18th Century B.C. they were influenced by the greek to study math. The Babylonian system of mathematics was sexagesimal numeral system From this we get the modern day usage of 60 seconds in a minute======

=
60 minutes in an hour, and 360 (60×6) degrees in a circle.This was a advanced civilization that built cities and supported the people with an irrigation system, a legal system, administration, and even a good postal service. Writing developed and counting was based on the sexagesimal system.======

=
He was born around the year 780 ,and maybe in Khwārizm[2][4][5],His Algebra, written around the year 820, was the first book on the systematic solution of linear and quadratic equations. He was one of the first people to use zero as a place holder in positional base notation.======

=
His contributions didn't only made a great impact on mathematics. but on language as well. he died somewhere around the year 850. He worked most of his life as a teacher in the House of Wisdom in Baghdad.======



=
2. The owner of a ranch decides to enclose a rectangular region with /310/ 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? the maximum area the rancher can enclose is 12,012.5ft ====== 3. A farmer wishes to enclose a rectangular region bordering a river using /2,400/ 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? the maximum area that can be enclosed with the fencing is 480,000 ft

phase 2 part 2

1.Part two of Phase 2 is to solve the problems that involve projectile in motion. The formula you will be using to solve these problems is below: s(t) = –gt2 + v0t + h0 Describe what the letters g, t, v and h represent.

g= the acceleration due to gravity //v= represents initial velocity h= represents the initial height from which the projectile is released //t= //represents time in seconds after the projectile is released//

2.Some fireworks are fired vertically into the air from the ground at an initial velocity of /74/ feet per second. Find the highest point reached by the projectile just as it explodes. the highest point reached by the projectile just as it explodes is 703/8

3.A ball is thrown vertically upward with an initial velocity of /75/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.

phase 3

1. You need to explain what does it mean to say “ solve by graphing” once you have this written on your wiki you will solve the quadratic by graphing. x =-b/2(a) a= 1 b=18 c=32 x =-18/2= 8 x=9

2. You need to explain what it means to say “solve the quadratic by factoring.” Once you have this written on your wiki you will then solve the same equation by factoring. What do the solutions represent after factoring a quadratic solving the quadratic by factoring means you solve the quadratic by factoring the equation (x+2)(x+16) (x=-2)(x=-16) 3. Last you need to explain what it means to say “solve the equation using the quadratic formula.” Put your explanation on your wiki and then take your equation and use the quadratic formula to solve it. Show the step-by-step process in solving this, on your wiki.
