Solve the problem.When water runs out of a hole in a cylindrical container, the height of the water in the container can often be modeled by a quadratic function. Assume that the height of the water in a particular metal can with a small hole can be modeled by h = 0.0005x2 - 0.17x + 8, where x is the time (sec) and h is the height (cm). Use the quadratic formula to estimate the time when the height is 5 cm. Round your answer to the nearest second.
