Chapter 11.3, Problem 8E

The Ferris Wheel ride at a carnival sits 3 meters above the ground and sends riders to a maximum height of 33 meters in the air. The equation y = 15sin(x) + 18 models the height of a rider with respect to the rotation of the ride and is represented as a graph in the xy-coordinate plane below

In Exercises 11-20, use a polar coordinate system like the one shown for Exercises 1-10 to plot each point with the given polar coordinates. 11. (2,45°) 12. (1,45°) 13. (3.90°) (2) (-1=) (4) (-2-) 4 15. (3, 3 16. (3, 6. 14. (2,270°) 37 17. (-1, 7) 18. 19. 2 20. (-3, —я)

Plot the point that has the given polar coordinates. (-3,1) x/2 0 x/2 x/2 x/2 0 Give two other polar coordinate representations of the point, one with r 0. (r. 8) = ) (smaller /-value) X (r, 8) = ) (larger /-value) 0
