It's 40 ft.

Since the rocket is launched from a platform, then the height of the rocket at 0 seconds will be the height of the platform.
h(t)=-16t^{2}+70t+40\\h(t)=-16(0)^{2}+70(0)+40\\h(t)=0+0+40=40ft

The table below shows the fourth roots of different numbers: Number (x) 16,16,81,81 Fourth root of the number (y) 2 −2 3 −3 Part
MA_775_DIABLO [31]
Part A) Y cannot be described as a function of x, because in order to be a function, there can only be one input, the x value, for every output, f(x) or the y value. Since the x value, 16, generates two y values, -2 and 2, this cannot be called a function. 

Part B) 
<span>f(x) = 25x + 16
f(20)= 25(20) + 16
f(20) = 500 + 16
f(20) = 516

This is the total cost, in dollars, of renting the truck for 20 hours. </span>
