Problem 7

Recall that the diameter of the Ferris wheel used in Chapters 2 and 3 is \(250\) feet and it rotates through one complete revolution every \(20\) minutes. Make a table that shows the riderÃ¢â‚¬â„¢s height \(H\) above the ground for each of the nine values of \(t\) shown in Figure 7. Then graph the ordered pairs indicated by the table. Finally, use the graph to find an equation that gives \(H\) as a function of \(t\).
