landon is standing in a hole that is 6.5 m deep he throws a rock and it goes up into the air, out of the hole and then lands on the ground above. The path of the rock can be modeled by the equation y=-0.05x^2+4.5x-6.5, where x is the horizontal distance of the rock, in meters, from Landon and y is the height in meters, of the rock above ground. How far horizontally from Landon will the rock land? Round the answer to the nearest hundredth of a meter.

Answer 1

it lands when the height is zero, so just solve
-0.05x^2+4.5x-6.5 = 0
