Answer: 42.25 feet
Step-by-step explanation:
We know that after "t" seconds, its height "h" in feet is given by this function:

The maximum height is the y-coordinate of the vertex of the parabola. Then, we can use the following formula to find the corresponding value of "t" (which is the x-coordinate of the vertex):

In this case:

Substituting values, we get :

Substituting this value into the function to find the maximum height the ball will reach, we get:

You doubled the investment in the product. You sold it for twice what you bought it for. So it increased by $750
10,14,18,22,26,30,34,38,42,46,50,54,58,62,66,70,74
Know that dividing by 3 is the same as multiplying by 1/3.
Thus, 8/5 * 1/3 = 8/15
