Solve the problem using the quadratic formula.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(x) = 0.0005x2 - 0.17x + 8, where x is the time (sec) and h is the height (cm). Use the quadratic formula to estimate the earliest time when the height is 3 cm. Round your answer to the nearest second.

A. 40 sec
B. 39 sec
C. 33 sec
D. 37 sec
