During a competition, an archer fires an arrow at a
target on a hill. The arrow reaches a maximum
height of 127 feet 2.75 seconds after it was fired.
The arrow hits the target 5 seconds after the archer
releases it. If the arrow is released from a height of
6 feet, how far above the ground on which the
archer is standing is the target? Assume the
relationship between time and height is quadratic.
