A group of participants has just completed a series of problems involving water jars. In each problem, the participants needed to fill the largest jar, pour from it once into the middle-sized jar, and then pour from the largest jar twice into the smallest jar. The participants are now given a new problem, which cannot be solved via this procedure. We would expect that the participants will

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?
