Jake is the kicker on the football team and has an amazing kick during the game. The path of the football can be measured by the function h = -0.625d(d - 56), where h represents the height of the football and d represents the horizontal distance from the player. How far away from Jake is the ball when it finally hits the ground?

A) 0

B) 28

C) 56

D) 280

Respuesta :

Option C is the correct answer.

Step-by-step explanation:

The path of the football can be measured by the function h = -0.625d(d - 56)

When the football lands the height of ball is zero.

That is h = 0

Substituting

           h = -0.625d(d - 56)

           0 = -0.625d(d - 56)

           d = 0 units  or d = 56 units

d = 0  units is initial position, which is not acceptable.

So when the ball hits the ground it is 56 units far away.

Option C is the correct answer.
