In Exercises \(110-113,\) graph each pair of functions in the same viewing rectangle. Use your knowledge of the domain and range for the inverse trigonometric function to select an appropriate viewing rectangle. How is the graph of the second equation in each exercise related to the graph of the first equation? $$y=\sin ^{-1} x \text { and } y=\sin ^{-1} x+2$$
Define the sine of \(t\).
On a carousel, the outer row of animals is 20 feet from the center. The inner row of animals is 10 feet from the center. The carousel is rotating at 2.5 revolutions per minute. What is the difference, in feet per minute, in the linear speeds of the animals in the outer and inner rows? Round to the nearest foot per minute.
