Question 1062728: When seated, and average adult breathes in and out every 4 seconds. The average minimum amount of air in the lungs is 80ml, and average maximum amount of air in the lungs is 800ml
a. Assuming that the lungs are at a minimum at t= 0, sketch the graph that represents the average amount of air in the lungs over time for at least 2 cycles
b. Determine the amplitude and vertical displacement, period and k value
c. Determine a possible value for the phase shift and justify your choice
d. Determine an equation that will model the given situation

When seated, and average adult breathes in and out every 4 seconds. The average minimum amount of air in the lungs is 80ml,
and average maximum amount of air in the lungs is 800ml
a. Assuming that the lungs are at a minimum at t= 0, sketch the graph that represents the average amount of air
in the lungs over time for at least 2 cycles
b. Determine the amplitude and vertical displacement, period and k value
c. Determine a possible value for the phase shift and justify your choice
d. Determine an equation that will model the given situation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
d.  V(T) = 440 - 360*cos((2pi*t)/4)


a.  Plot:





Plot  V(T) = 440 - 360*cos((2pi*t)/4)



b.  Amplitude = %28800-80%29%2F2 = 360 mL


    Average value = %28800%2B80%29%2F2 = 440 mL


    Period = 4 seconds.
