A model rocket is launched from the top of a building 160 feet from the ground. The relationship between the time in seconds, x, and the vertical height in feet, y, is represented by this equation.
y=-40x^2 + 120x+ 160

A. Rewrite the equation in a form that shows the time it takes the rocket to land on the ground. Use the equation to find the time. Explain your work.

B. Rewrite the original equation, y= -40x^2 + 120x +160, in a form that shows the maximum height of the rocket. Use the equation to determine the maximum height. Explain your work.

C. Write an equation that increases the maximum height reached by the rocket but doesn't change the time it takes for the rocket to land on the ground. Explain your answer.
