Respuesta :

The approximate maximum height that the soccer ball reaches is 9.8 ft. The correct answer between all the choices given is the third choice or letter C. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

Answer:

C: 9.8 ft

Step-by-step explanation:

H(t) = -16t^2 + vt + s

v = 25 ft per sec

s = 0

H(t) = -16t^2 + 25t + 0

a= -16, b= 25, c= 0

vertex fomula =  - b/2a

- 25/2(-16)

= -25/-32

t = .781

-16(.781)^2 + 25(.781) + 0

-16(.61) + 19.53 + 0

-9.76 + 19.53

= 9.77

Vertex = (.781, 9.77)

Answer:  The maximum height is 9.8 ft
