Question

A stunt diver jumps from the top of a 40-meter platform. The diver's height above the water is modeled by h = -5t2 + 10t + 40, where h is the height in meters and t, is the time in seconds. What is the height of the stunt diver at 3 seconds?

Answer 1

Given

h = -5t2 + 10t + 40

h is the height in meters and t, is the time in seconds

What is the height of the stunt diver at 3 seconds?

Procedure

`\begin{gathered} h(t)=-5t^2+10t+40 \\ h(3)=-5(3)^2+10(3)+40 \\ h(3)=-45+30+40 \\ h(3)=25 \end{gathered}`

the answer is 25 meters
