Question

IMPORTANT! PLEASE HELP!

Kay was walking along the bridge above the river. She accidentally lost her grip on her camera when she was trying to get it out to photograph massive bird nests in the trees. The height of the camera above the water can be modeled by the equation

y = -16t^2 + 400, where t represents the seconds after the camera is dropped. How long will it take (in seconds) before Kay sees the splash from the camera hitting the water.

Answer 1

Answer: In 5 seconds Kay will see the splash before the camera hits the water

Explanation:

Answer 2

y=-16t²+400
add -16t² to both sides
-16t²=-400
divide both sides by 16
t²=-25
t=√25
t=5

So in 5 seconds the camera will hit the water.
