The function H(t) = −16t2 + 75t + 25 shows the height H(t), in feet, of a baseball after t seconds. Part A: After how many seconds does the baseball hit the ground? You do not need to show your work. Part B: What is the maximum height of the baseball? You do not need to show your work.

Step-by-step explanation:

Given that,

The function that shows the height of a baseball after t seconds is given by :

....(1)

Part (A).

When the baseball hits the ground,

H(t) = 0

So,

After 5 seconds the baseball will hit the ground.

Pat (B)

For maximum height, put dH/dt = 0

So,

Put t = 2.34 s in equation (1).

Hence, this is the required solution.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

answer:   c ?
