Question

A group of engineering students construct a potato cannon. The height, h in meters, of a
potato t seconds after it is shot from the cannon that is on the roof of a building is modeled by
the equation h = - (t - 7)2 + 45.
a) How high is the potato after 4 seconds?
b) When does the potato reach it maximum height? Explain your answer.
c) What is the maximum height? Explain your answer.

Answer 1

So we have \[-(t-7)^2+45\] plug in 4 as t, and you'll get A
For Part B, an easy way to do it is graph it on Desmos, and the x value of the maximum point will be your answer
For Part C, the y value of the maximum point would be your answer o-O

Answer 2

thank you!
