a model rocket is launched from a roof into a large field the path of the rocket can be modeled by the equation y = -0.06x^2 + 9.6 + 5.4 where x is the horizontal distance in meters from the starting point on the roof and y is the height in meters of the rocket above the ground how far horizontally from its starting point will the rocket land?

A: 4.30 m
B:160.56m
C:161.12m
D:13.94m

    did you use the quadratic formula?
    how did you do it?
