ROCKETS The height h of a model rocket
launched from ground level into the air
after I seconds can be modeled by the
equation h=-1612 + 160r. The
equation is graphed on the coordinate grid.

AWhere does the graph intersect the x-axis? What do these points represent?
The x-intercepts are Select Choice and Select Choice. The x-intercepts represents

Select Choice
BHow long does it take the rocket to reach its maximum height? Explain your reasoning.
It takes Select Choice seconds for the rocket to reach its maximum height.
The maximum of the graph appears to be Select Choice feet. Substitute that value into the equation and solve
fort. So, the maximum height occurs at Select Choice seconds.
