OLUTION: a fountain shoots out water that follows a parabolic curve. water comes ... and goes in another port on the ground as well. if the ports are 15 feet away a ... if the axis of symmetry of the parabola is at x = 0, then the vertex will be at (0,12). ... equation of y = a * (x^2 - 56.25) becomes y = -16/75 * (x^2 - 56.25) which ...

(by cross multiplication)

16(x+1)=15(x+1)

16x+16=15x-15

16x-15x=-15-16

x= -31

hope it helps.........^_^
