if time at altitude x is y, then y = ax+b Now, b=0, since a jump from 0 feet takes 0 time. So, y = ax 120 = 2880a a = 120/2880 = 12/288 = 1/24 y = x/24 the speed is thus ft/s = x/y = 24 ft/s

calculus?
assuming the garage will be one of the long sides (otherwise lots of extra fencing will be used), then if the long side is x, the short side will be 50/x. So, the amount of fence, f, is f(x) = x + 2(50/x) = x + 100/x df/dx = 1 - 100/x^2 we want minimum fence, so df/dx = 0: x...

Calculus
the square has to be at least 10x10, using 40 yds of fence. That leaves 240 yds for the rectangle, so X+2X&lt;=120, or X &lt;= 40. If X = 40, 2X = 80, so area = 3200 If 2X^2 = 800, X=20, so 20 &lt;= X &lt;= 40 As X increases from 20 to 40, the area increases ...

math -fractions
Change these fractions to equivalent fractions with the same denominator. 1/2 = 60/120 7/8 = 105/120 9/10 = 108/120 1/3 = 40/120 3/5 = 72/120 1/4 = 30/120 Now you can arrange them in order.
