Question

The tides around Cherokee Bay range between a low of one foot to a high of five feet. The tide is at its lowest point when time, t, is 0 and completes a full cycle over a 24 hour period. What is the amplitude, period, and midline of a function that would model this periodic phenomenon?

Answer 1

amplitude = 4 feet; period = 24 hours; midline: y = 3

amplitude = 2 feet; period = 12 hours; midline: y = 2

amplitude = 2 feet; period = 24 hours; midline: y = 3

amplitude = 4 feet; period = 24 hours; midline: y = 2

Answer 2

I am so stuck on this

Answer 3

how about this one then?
What is the amplitude, period, and phase shift of f(x) = −4 sin(2x + π) − 5?

Answer 4

amplitude = −4; period = 2π; phase shift: x = negative pi over two

amplitude = −4; period = π; phase shift: x = pi over two

amplitude = 4; period = π; phase shift: x = negative pi over two

amplitude = 4; period = 2π; phase shift: x = pi over two
