Given the depth vs. clock time function y = f(t) = .02 t2 + -2.02 t + 54, with depth in cm when clock time is in seconds, find the clock time t such that f(t) = 39.995 cm and find f(t) when t = 22 cm. Find the clock time when water depth is 9.995 cm. Using the same function determine the depth at clock time t = 10 sec.
