Tiffany kicks a soccer ball off the ground and in the air, with an initial velocity of 28 feet per second. using the formula h(t) = −16t2 + vt + s, what is the maximum height the soccer ball reaches?

The maximum height of soccer ball  is 12.25 ft.

Step-by-step explanation:

It is given that Tiffany kicks a soccer ball off the ground and in the air, with an initial velocity of 28 feet per second. It means v = 28 ft.

Given formula is

The initial height of ball is 0.

The height of ball defined by the function

It is a downward parabola and the vertex of a downward parabola is the point of maxima.

The vertex of a parabola is

Therefore the maximum height of soccer ball  is 12.25 ft.

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
