Question 1026872: A model rocket is launched from a roof into a large field. The path of the rocket can be modeled by the equation
y equals negative 0.04x squared plus 8.3x plus 4.3, 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? Round your answer to the nearest hundredth meter. (1 point)
208.02 m
416.03 m
0.52 m
208.19 m

A model rocket is launched from a roof into a large field. The path of the rocket can be modeled by the equation
y equals negative 0.04x squared plus 8.3x plus 4.3, 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? Round your answer to the nearest hundredth meter.
-------
y = -0.04x^2 + 8.3x + 4.3
The "rocket" lands when y = 0
-0.04x^2 + 8.3x + 4.3 = 0
-0.04,8.3,4.3

Ignore the negative solution
x =~ 208.02 meters
