Given the depth vs. clock time function y = f(t) = .02 t2 + -2.07 t + 63, with depth in cm when clock time is in seconds, find the clock time when water depth is 31.43875 cm. Using the same function determine the depth at clock time t = 10 sec. Find t such that f(t) = 59.43875. Find f(t) when t = 24.
