When two factors equal 0 what does that tell you about the factors?
Solve using the Zero Product Property:
The height of a football after it has been kicked from the top of a hill can be modeled by the equation h = 2 (-2 -4t) (2t - 5) , where h is the height of the football in feet and t is the time in seconds. How long is the football in the air?
Solve using the Zero Product Property:
The depth of a scuba diver can be modeled by the equation d = 0.5t(3.5t - 28.25) , where d is the depth in meters of the diver and t is the time in minutes. Find the time it takes for the diver to reach the surface. Give your answer to the nearest minute.
Solve using the Zero Product Property:
The height of a flare fired from a platform can be modeled by the equation
h=8t( -2t + 10)+4(-2t + 10), where h is the height of the flare in feet and t is the time in seconds. Find the time it takes for the flare to reach the ground.
