The chesapeake bay tides vary between 4 feet and 6 feet. the tide is at its lowest point when time (t) is 0 and completes a full cycle in 12 hours. what is the amplitude, period, and midline of a function that would model this periodic phenomenon? amplitude = 1 foot; period = 12 hours; midline: y = 5 amplitude = 2 feet; period = 6 hours; midline: y = 1 amplitude = 2 feet; period = 12 hours; midline: y = 5

The correct option is 1.

Step-by-step explanation:

The general cosine function is

where, A is amplitude, is period, C is phase shift and D is midline.

It is given that the Chesapeake Bay tides vary between 4 feet and 6 feet. it means the minimum value is 4 and maximum value is 6.

Amplitude of the function is

Therefore the amplitude of the function is y=5.

Midline of the function is

Therefore the midline of the function is y=5.

It completes a full cycle in 12 hours.

hours

Period of the function is 12 hours. Therefore the correct option is 1.

tube or goog would be a great resource to with that question

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
