Answer:
h(t) = = -16t^2 + 167t + 135
Step-by-step explanation:
This is an equation of motion of an object umder a constant acceleration(here it is the acceleration due to gravity);
h(t) = = -16t^2 + 167t + 135.
Note: t is the time in seconds and h is the height in feet at time t.

Given two points (x₁,y₁) and (x₂,y₂) the midpoint would be:
M=((x₁+x₂)/2 , (y₁+y₂)/2)
In this case, the points would be: (-8,-7) and (-7,-8); therefore:
M=((-8-7)/2 , (-7-8)/2)=(-15/2,-15/2)
Answer: C.) (-15/2 , -15,2)
