a ferris wheel of diameter 18.5m rotates at a rate of 0.2rad/s. if passengers board the lowest car at a height of 3m above the ground, determine a sin function that models the height \, h, in meters, of the car relative to the ground as a function of the time, t, in seconds.

The change in water level of a lake is modeled by a polynomial function, w(x). described how to find the x-intercepts of w(x) and how to construct a rough graph of w(x) so that the parks department can predict when there will be no chage in the water level. you may create a sample polynomial of degree 3 or higher to use in your explanations.
