Sea levels follow a periodic pattern of rise and fall called the tides. The sea level at a certain beach, in feet, is given by the function f, left bracket, t, right bracket, equals, 1, point, 9, 2f(t)=1.92 cosleft bracket, start fraction, pi, divided by, 6, end fraction, left bracket, t, minus, 5, point, 5, right bracket, right bracket, plus, 1, point, 9, 6( 6 (t5.5))+1.96, where time tt is measured in hours after 12:00 a.m. (midnight). What is the maximum and what does it represent in this context
