The path of water from a hose on a fire tugboat can be approximated by the equation

y = −0.0055x2 + 1.2x + 10,
where y is the height, in feet, of the water above the ocean when the water is x feet from the tugboat. When the water from the hose is 3 feet above the ocean, at what distance from the tugboat is it?

1 answer

just solve for x in

−0.0055x2 + 1.2x + 10 = 3
