Steady states If a function f represents a system that varies in time, the existence of lim t → ∞ f ( t ) means that the system reaches a steady state (or equilibrium). For the following systems, determine whether a steady slate exists and give the steady -state value . 75. The amplitude of an oscillator is given by a ( t ) = 2 ( t + sin t t ) .

3. The average temperature in Detroit, Michigan on any given day of the year can be modeled
by T(t) = 27 sin(0.0172(t- 115) + 50, where T is the temperature in degrees Fahrenheit and
t is the number of days elapsed since January 1st.
(a) State the period (in days), the amplitude, the vertical shift, and the phase shift. Interpret all four
of these in the context of the real-world situation being modeled.
The temperature in Gavin's oven is a sinusoidal function of time. Gavin sets his oven so that it has a maximum temperature of 300°F and a minimum temperature of 240°. Once the temperature hits 300°, it takes 20 minutes before it is 300° again. Gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 290°. He puts the cake into the oven when it is at 270° and rising. How long will Gavin need to leave the cake in the oven? (Round your answer to the nearest minute.)
The answer to this question has to be the time in minutes rounded to the nearest integer in which the cake should be in the oven.
The San Francisco Bay tides vary between 1 foot and 7 feet. The tide is at its lowest point when time (t) is 0 and completes a full cycle in 8 hours. What is the amplitude, period, and midline of a function that would model this periodic phenomenon?
A. Amplitude = 6 feet; period = 8 hours; midline: y = 4
B. Amplitude = 6 feet; period = 4 hours; midline: y = 3
C. Amplitude = 3 feet; period = 8 hours; midline: y = 4
D. Amplitude = 3 feet; period = 4 hours; midline: y = 3
