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

Amplitude = 1 foot; period = 12 hours; midline: y = 5

Step-by-step explanation:

The Chesapeake Bay tides vary between 4 feet and 6 feet.

This means the range is

The period is the length of the interval on which the function completes one full cycle.The tide is at its lowest point when time (t) is 0 and completes a full cycle in 12 hours.

The interval is [0,12] and its length is 12, hence the period is 12.

The midline

The amplitude is the distance from the midline to the peak.

The amplitude is |5-4|=|5-6|=1

The first choice is correct.

answer: two five pound bags one two pound

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
