Residential power consumption has shown certain trends over recent years. Based on date reflecting average usage, engineers at the power company have modeled a town's rate of energy consumption by the function r(t) = 4 + sin(0.263t +4.7) + cos(0.526t+ 9.4) Here, t measures time in hours after midnight on a typical weekday, and r is the rate of consumption in megawatts at time t. a) Using a graphing calculator (or equivalent), sketch a carefully labelled graph of r(t) on the interval [0,24].

The kinetic energy E of an object varies jointly with the object’s mass m and the square of the object’s velocity v . An object with a mass of 50 kilograms traveling at 16 meters per second has a kinetic energy of 6400 joules. What is the kinetic energy of an object with a mass of 70 kilograms traveling at 20 meters per second?
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?

Suppose that you are on the beach on December 25th and notice high tide occurs at 1:00 pm with a depth of 1.6 meters. You then return at 8:00 in the evening and notice it is low tide at 0.2 meters. Find the cosine function that represents the depth as a function of time in hours that have elapsed since 12:00 midnight at the beginning of December 25th. Assume that the depth varies sinusoidally with time. Draw the graph to represent this situation. Remember, t=0 represents midnight. Clear All Draw: Determine the following characteristics of the sinusoidal function: Amplitude Period Hours Sinusoidal axis: y Write the cosine function that models the following problem.
