The volume v, in liters, of air in the lungs during a four-second respiratory cycle is approximated by the model v = 0.1729t + 0.1522t2 − 0.0374t3, where t is the time in seconds. approximate the average volume of air in the lungs during one cycle. (round your answer to four decimal places.)

0.7296 liters

Step-by-step explanation:

The volume of air in the lungs during a four seconds respiratory cycle is approximated by the model by

V = 0.172 (4) + 0.1522 (4)² - 0.0374 (4)³

  =  0.688 + 2.4352 - 2.3936

  = 0.7296 liters

Therefore, average volume of the air in the  lungs in one cycle is 0.7296 liters.
