document.write( "Question 797747: 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 fraction. Assume that the height of the water in a particular metal can with a small hole can be modeled by h=0.0003x^2-0.16x+8, where x is the time (sec) and the h is the height (cm). Use the quadratic formula to estimate the time when the height is 7 cm. Round your answer to the nearest second.
