Acrane lifts a load by means of a pulley. the wheel of the pulley has a diameter of 42 cm . the load is pulled up at a uniform. rate of 0.8 m/s and takes two minutes to reach the desired level . calculate the number of complete revolutions. the wheel makes to raise the load.

Me find the value of x each figure.

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?
