Algebra 2 2nd Quarter Extra Credit:
Last chance for extra credit before the semester is over. Use the following equation for the height of the water to solve the following problem.

For a bathtub with a rectangular base, the height of the water in the tub h, t seconds after it begins draining is given above. Suppose you fill a tub completely full, the tub is 72 inches long by 28 inches wide by 28 inches high. The drain has a 2 inch diameter. a) Find the time it takes for the tub to go from full to half-full. b) Find the time it takes for the tub to go from half-full to completely empty.
