Lauren dove into a swimming pool from a 15 foot high diving board with an initial upward velocity of 8 feet per second find the time it took one to enter the water use the equation h=-16t^2 + vt + s, where h is height in feet, t is time in seconds, v is the initial upward velocity in feet per second, and s is the initial height in feet.

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?
