PLZ HELP GRADE DEPENDS ON THIS(40pts.) The Cobscook Bay tides vary between 4 feet and 20 feet. The tide is at its lowest point when time (t) is 0 and completes a full cycle in 18 hours. What is the amplitude, period, and midline of a function that would model this periodic phenomenon?

Amplitude = 16 feet; period = 9 hours; midline: y = 8
Amplitude = 16 feet; period = 18 hours; midline: y = 12
Amplitude = 8 feet; period = 9 hours; midline: y = 8
Amplitude = 8 feet; period = 18 hours; midline: y = 12
