Asoccer ball is kicked from the ground in an arc defined by the function, h(x) = -8x 2 + 64x. at what point does the ball hit the ground?
(0,4)
(0,8)
(4,0)
(8,0)

The soccer ball hit the ground at (8, 0)

Solution:

To find at what point the ball hit the ground we make the given function equal to zero.

Here the given function is

We make h(x) = 0 and try to find the value of x

h(x) = 0

-8x (x - 8) = 0

-8x = 0 or (x - 8) = 0

Therefore x = 0 or x = 8

At x= 0 the ball was not kicked. Now we try to find the value of the function by substituting x = 8 in the given function and find the value of the function.

=-512 + 512  = 0

Thus the ball hit the ground at (8,0).

answer: i cant see the picture

step-by-step explanation:

can u take a better picture

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
