Asoccer ball is kicked off 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)

(8,0)

Step-by-step explanation:

The equation that models the path traced by the ball is

To find the point at which the ball hit the ground, we must equate the function to zero.

Factor;

This implies that;

x=0,x=8,

At x=0, the ball was not yet kicked.

So we take x=8, to be the time the ball hit the ground.

We substitute x=8 into the function to get;

Hence the point at which the ball hit the ground is (8,0)

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
