The last question 4. is 1.5 56ft plz god bless u and ur grades

First option.

Step-by-step explanation:

You know that the following function model the height "h" of the ball (in feet) after a time "t" (in seconds):

Notice that it is a Quadratic function, therefore, it is a parabola.

Then, the x-coordinate of its vertex will give you the time in seconds in which the balll reaches its maximum height and the y-coordinate of the vertex will give you the ball's maximum height.

 You can find the x-coordinate of the vertex with this formula:

You can identify that:

Substituting values, you get:

FInally, you must substiute this value into the Quadratic function and then evaluate in order to find the ball's maximum height.

This is:
