Kristen boards a Ferris wheel at the 3-o'clock position and rides the Ferris wheel for multiple rotations. The Ferris wheel radius is 15 meters long and the center of the Ferris wheel is 20 meters above the ground. Imagine an angle with its vertex at the Ferris wheel's center that subtends the path Jane has traveled. The Ferris wheel rotates at a constant rate so that the angle sweeps out 7 radians per minute. How long does it take for Kristen to complete one full rotation around the Ferris wheel? a. 6/14 ~ 0.429 minutes.
b. 6/2 pi ~ 0.955 minutes.
c. 2 pi .14/6 ~ 14.661 minutes.
d. 2 pi/6 ~ 1.047 minutes.
e. 14/6 ~ 2.333 minutes.

Hye ryung is the president of the local chapter of the american medical students association (amsa). she is organizing local outreach and informational meetings. at her first meeting there are five people present (including herself). every month after that her group grows by 5 people. a. how many members are in the group after 6 months? b. the logistics of hosting and feeding her group at meetings was more complicated than expected. the cost of feeding 5 people at her first meeting was $30, for 10 people it was $35, for 15 it was $45, and after 6 months all of the costs had added up to $100. write a function to model the cost with the number of people attending meetings. c. what connections can you make between the linear growth of the group’s membership and the increasing costs of running meetings?
