The Saginaw Bay tides vary between 2 feet and 8 feet. The tide is at its lowest point when time (t) is 0 and completes a full cycle in 16 hours. What is the amplitude, period, and midline of a function that would model this periodic phenomenon?

Best ResponseYou've already chosen the best response.1the tide has a low of 2ft and high of 8 fft the amplitude is half the distance between the low and high tides

Best ResponseYou've already chosen the best response.0Ohh so it's either A or B.

Best ResponseYou've already chosen the best response.1the midline is found by taking the low tide and adding the amplitude
