Given the depth vs. clock time function y = f(t) = .016 t² + -2.18 t + 93, with depth in cm when clock time is in seconds, find the clock time t such that f(t) = 56.74375 cm and find f(t) when t = 37 cm. Find the clock time when water depth is 25.74375 cm. Using the same function determine the depth at clock time t = 13 sec.
