Question

I really need help on this Please
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+9.6x+5.4 where x is the horizonal 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? Round your answer to the nearest hundredth.

1.4.30m
2.160.56m
3.160.23n
4.3.94m

Answer 1

If the rocket hits the ground, y will equal zero. Take advantage of this fact to write a quadratic equation in x set equal to zero. Then solve that quadratic equation in whichever way you find easiest (e. g., quadratic formula, factoring, completing the square, graphing, and so on).

Answer 2

ok this is what I got but don't know what to do with it from there
x=-0.5605
x= 160.5605

Answer 3

lol nevermind am brain dead

Answer 4

So you've obtained two tentative solutions (as expected). Discard the (-) one. Compare the remaining one to the answer options given.
