a ferris wheel has a radius of 70 feet and makes a revolution every 60 seconds, the center of the wheel is 90 feet above the ground. the ferris wheel goes counter clockwise. write an equation to model the height of a rider who starts the ride at the 3:00 position? also what is the amplitude, vertical translation and the period

Write an exponential function - I set a 16 1b. block of ice out in the sun on a hot day. 2 hours later I came back and weighed the remaining ice. it weighs 9 lbs. if I know that ice melts at an exponential rate, write an equation that can be used to model the weight of the ice (w) after a given number of hours (h) use your equation to predict the weight of the ice at 5 hours.
