Think About the Process Ajar contains only pennies, nickels, dimes, and quarters. There are 22 pennies, 23 dimes, and 16 quarters. The rest of the coins are nickels. There are 82 coins in all. How
many of the coins are not nickels? If n represents the number of nickels in the jar, what equation
could you use to find n?

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d. what is the height of the tide after 93 hours?
