On a vacation to puerto rico rose jumped off a cliff into a river in elion forest preserve her height as a function of time to be modeled by the function hft equal 16 t squared +16 t +480 where t is the time after jumping in seconds and h is the height in feet how many seconds it take rose to hit the water round your answer to the nearest hundredth

To solve for t, you will use the equation given: -16t^2 + 16t + 480 = 0. First, simplify the equation by dividing everything by 16: -t^2 + t + 30 = 0. Then complete reverse FOIL: (-t + 6)(t + 5) = 0. Next, set each of these equations to 0 separately, and solve for t. You will get t = 6, and t = -5. Since time can't be negative (Rose can't have hit the water after a negative number of seconds), the answer is 6.
