- 6. A Ferris wheel is 200 ft in diameter with its lowest point 3 ft off the ground. Once all the passengers have been loaded, the wheel makes one full rotation counterclockwise in 3 min. Suppose that a couple is seated at the lowest point on the wheel and are the last passengers to be loaded. a. Write a model representing the couple's horizontal position x (in feet) relative to the center of the Ferris wheel, t minutes after the ride starts. b. Write a model representing the couple's height y (in feet) above ground level, t minutes after the ride starts. c. Give the coordinates of the couple's position 2 min into the ride and tell if they are going up or down. Round to the nearest tenth of a foot.arrow_forwardHw 1) By uing the of 3 deurv ahve 3x° at %3D X=2 .arrow_forwardQuestion 3b.)arrow_forward
- 1. The propeller of a boat at dock in the ocean will rise and fall with the waves. On a particularly wavy night, the propeller leaves its resting position and reaches a height of 2.5 m on the peaks of the waves and -2.5 m in the troughs. The time between the peak and the trough is approximately 2 seconds. Determine the equation of a sinusoidal function that would model this situation assuming that at t = 0, the propeller is at its resting position and headed towards the peak of the next wave.

True O False A Moving to another question will save this response. ASUSarrow_forwardQuestion 3 Sheep's Wool Length: For sheep maintained at high environmental temperatures, respiratory rate, r(per minute), increases as wool length, /(in centimetres), decreases. Suppose sheep with a wool length of 2 cm have an (average) respiratory rate of 160, and those with a wool length of 4 cm have a respiratory rate of 125. Assume that r and / are linearly related. a) Find an equation that gives r in terms of /. b) Find the respiratory rate of sheep with a wool length of 1 cm.arrow_forward
