In steinhatchee in july, high tide is at noon. the water level is 5 feet at high tide and 1 foot at low tide. assuming the next high tide is exactly 12 hours later and the height of the water can be modeled by a cosine curve, find an equation for steinhatchee's water level in july as a function of time (t). a) f(t) = 6 cos pi over 2 t + 2 b) f(t) = 2 cos pi over 2 t + 3 c) f(t) = 2 cos pi over 6 t + 3 d) f(t) = 6 cos pi over 6 t + 2
