Answer:
Kindly check explanation
Step-by-step explanation:
Given the model equation:
h (t) = 3 + 70t - 16t²
h = height in feet
t = time in seconds
Average rate of change in h(t) between
t= 1 second and t = 3 second
At t = 1 second
h(1) = 3 + 70(1) - 16(1)^2 = 57
At t = 3 second
h(3) = 3 + 70(3) - 16(3)^2 = 69
Average rate of change = Δh / Δt
Δh / ΔT = [h(3) - h(1)] / (3 - 1)
= (69 - 57) / 2
= 12 / 2
= 6
Hence, it is the mean or average change in height h as time, t changes
