A basketball player shoots a free throw in a game. The quadratic expression models the height of the ball, in feet, where t is the time, in seconds.

-16t^2 + 25t+7

What does the constant, 7, in the expression represent?

A.

the initial velocity of the ball when the player releases it

B.

the maximum height the ball reaches while in the air

C.

the initial height of ball when the player releases it

D.

the total time the ball spends in the air

the initial height of ball when the player releases it

Step-by-step explanation:

A basketball player shoots a free throw in a game. The quadratic expression models the height of the ball, in feet, where t is the time, in seconds.

y = - 16t^2 + 25t+7

Given equation is in the form of

y = - 16x^2 + V t + h

Where V represents the initial velocity and h represents the initial height of the ball

Now we compare our equation with the general equation

We have 7 in the place of h

So, 7 is the initial height of the ball

Answer is 7 is the initial height of ball when the player releases it

A, D, E
