Given the depth vs. clock time function y = f(t) = .02 t² + -2.58 t + 99, with depth in cm when clock time is in seconds, find the clock time t such that f(t) = 96.79501 cm and find f(t) when t = 26 cm. Find the clock time when water depth is 48.795 cm. Using the same function determine the depth at clock time t = 12 sec.
