The Colossus Ferris wheel debuted at the 1984 New Orleans World's Fair. The ride is 180 ft tall, and passengers board the ride at an initial height of 15 ft above the ground. The height above ground, h, of a passenger on the ride is a periodic function of time, t. The graph displays the height above ground of the last passenger to board over the course of the 15 min ride.

Draw a graph that pictures the following situation. Identify the independent and dependent variables. Determine the intervals on which the dependent variable is increasing, decreasing, or constant. A woman left her office at 7:30 to attend a meeting. After walking for 3 minutes, she realized she forgot her notes and returned to get them. She picked up her notes and resumed her walk to the meeting, arriving at 8:00. After 14 minutes, the meeting was over and the woman returned to her office. Assume that the woman walks from the place of the meeting back to her office at the same speed with which she walks from her office to the place of the meeting after picking up her notes. Draw a graph that pictures the given situation. Choose the correct graph below. OA. OB. Oc. OD. AD AC Identify the independent and dependent variables. O A. The independent variable is the time t and the dependent variable is the distance D. O B. The independent variable is the distance D and the dependent variable…
