Given the depth vs. clock time function y = f(t) = .02 t² + -2.15 t + 93, with depth in cm when clock time is in seconds, find the clock time when water depth is 41.21874 cm. Using the same function determine the depth at clock time t = 10 sec. Find t such that f(t) = 91.21874. Find f(t) when t = 24.
