i hope this !
option b. 215.56 is the right answer.
path of the rocket can be modeled by the equation y = -0.04x²+8.6x+4.8
here y represents the vertical height of the rocket and x represents the horizontal distance in meters.
we have to calculate the horizontal distance covered by the rocket.
now we can say when rocket is landing y = 0 or vertical distance of the rocket will be zero.
then equation will be
-.04x²+8.6x+4.8 = 0
hello : 4xy (2x +3y)
8x²y +12xy² = 4xy (2x +3y)
