Question

Greetings, I need help finding the correct answer for the followingproblem: Problem: Aaron is in his tree house 12ft.above the ground. He asked his mother to throw his baseball up tohim. The equation h(t) = -18t2 + 27t + 3 represents theheight h of the baseball t sec. after it has beenthrown. If Aaron does not catch the ball, what is the total time theball is in the air? Justify your answer. Thanks! Greetings, I need help finding the correct answer for the followingproblem: Problem: Aaron is in his tree house 12ft.above the ground.

Explanation / Answer

To find the total time the ball is in the air, you need to find thetimes when h(t) is equal to zero (there will be two) and take thedifference between those two t-values. Plug the quadratic into thequadratic equation.
