A basketball player shoots a free throw in a game. The quadratic expression models the height of the ball, in feet, where t is t
Temka [501]

Answer:

 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

(40 pts)can you factor the difference of square?perfect square trinomials?
stira [4]

Answer:

Step-by-step explanation:

The difference of two squares may be represented by the formula:  a^2-b^2,

which can be factored as (a+b)(a-b)

A perfect square trinomial may be represented by the formula: a^(2)-2ab+b^2 or  a^(2)+2ab+b^2, depending on the sign of b

if b is negative: use the formula a^(2)-2ab+b^2, which can be factored as (a-b)*(a-b) or (a-b)^(2)

if b is positive: use the formula a^(2)+2ab+b^2, which can be factored as (a+b)*(a+b) or (a+b)^(2)
