Question 907494: Hello,
It's been awhile since I asked this question. I have not gotten any response yet.
If a paper plane is thrown from the top of an 147ft cliff into water,the height of the plane at any given time can be determined by h = -3t^2 + 147, where h is the height of plane at t seconds. After how many seconds will the plane be at height of 20.25ft?
I have h = 3t^2 + 147
h(t) = 3^2 + 147 - 20.25ft
147 = 3t^2 = 6t = 147
0 = 3t^2 + 6t
