An archer releases an arrow with an initial velocity of 30 feet per second at a height of 3 feet. The patff the arrow takes can be modeled using the function f (x) = -16x2 + 30x + 3, where f(x) represents the height, in feet, of the arrow and x represents the time the arrow travels in seconds. How many seconds until the arrow hits the ground? Round your answer to the nearest hundredth if necessary. Do not include units in your answer.
