.
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 = = 360 mL
Average value = = 440 mL
Period = 4 seconds.
