14. A model rocket is launched from a roof into a large field. The path of the rocket can be modeled by the equation y = 0.04x+ 8.3x + 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? (1 point)
208.02 m
416.03 m
0.52 m
208.19 m

my answer is C
is that correct?

Is it 0.004x^2?

anonymous · Answer

its 0.04^2

anonymous · Answer

y = 0.04x^2+ 8.3x + 4.3

btaylor · Answer

I tried it in the quadratic formula, solving for y=0, but it gave two negative numbers.

anonymous · Answer

i'm confused? is my answer incorrect or correct..

btaylor · Answer

I don't think the question is right.

anonymous · Answer

haha most likely your math is wrong.. Unless it's a type-O xD then I guess you'd be correct
