Aroller coaster moves along an inclined linear path before it reaches its maximum height. the car moves at a constant speed and gains 4 meters in height every 3 seconds.
the slope of the line that represents the height of the car in meters in terms of time in seconds is .
if the car takes 54 seconds to reach the maximum height, then the maximum height above the ground is meters.

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?
