Precalculus 1, select one of the answers below if necessary. Thank you! 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 = 0.85 sinwhere t is the time (in seconds). (Inhalation occurs when v > 0, and exhalation occurs when v < 0.)(a) Find the time for one full respiratory cycle.sec(b) Find the number of cycles per minute.cycles/min(c) Sketch the graph of the velocity function.
