The height of a buoy on a lake is changing during a storm. The height's rate of change can be modeled by r(t) = 0.5 cos(0.2t) feet per second where t is measured in seconds. Is the buoy's height increasing or decreasing at time t = 10 seconds? Why?

In Figure 208, gear A is turning at 120 revolutions per minute and gear B is turning at 3.6 revolutions per second. Determine the ratio of the speed of gear A to the speed of gear B.
A driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.m. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 10.7 gallons. What is the average rate of flow of the gasoline into the gas tank?
For a person at rest, the velocity v (in liters per second) of airflow during a respiratory cycle (the time from the beginning of one breath to the beginning of the next) is modeled by v=0.85sint/3, where t is the time (in seconds). a Find the time for one full respiratory cycle. b Find the number of cycles per minute. c Sketch the graph of the velocity function. Use the graph to confirm your answer in part a by finding two times when new breaths begin. (Inhalation occurs when v0, and exhalation occurs when v0.)
Over a 24-hour period, the tide in a harbor can be modeled by one period of a sinusoidal function. The tide measures 5.15 ft at midnight, rises to a high of 10.2 ft, falls to a low of 0.1 ft, and then rises to 5.15 ft by the next midnight. What is the equation for the sine function f(x), where x represents time in hours since the beginning of the 24-hour period, that models the situation?

A hot air balloon rising upwards is noticed by an observer who is 4 miles from where it is released. At this exact moment, the angle between the observer's line of sight and the horizontal is pi/3 radians. The angle of elevation is changing at 0.3 radians per minute. How fast is the hot air balloon rising right now?
The Eiffel Tower, in Paris France, is approximately 324 meters tall. A camera is 85 meters from the base of the tower and is moving along the horizontal ground away from the tower while keeping the top of the tower in view. What is the camera's horizontal velocity when the angle of elevation (to the top of the tower) is decreasing at 0.11 radians per second? m/s You may round your final response to two decimal places.
The actual temperature inside an oven varies around the selected temperature. This variation can be modeled with a sine function. If the cook selected a temperature of 375°F, then the actual temperature T in the oven is given by T = 5 sin(57x) + 375, where it is the number of hours since the oven first hit the selected temperature of 375°F. What is the highest actual temperature in the oven? 'F What is the lowest actual temperature in the oven? What is the period of this function? Give your answer in minutes. minutes When is the first time the oven will hit the highest temperature? Give your answer in minutes. minutes
