Answer:
The average volume of air in the lungs during one cycle is 0.53176 liters.
Step-by-step explanation:
Given : The volume V, in liters, of air in the lungs during a five-second respiratory cycle is approximated by the model , where t is the time in seconds.
To find : The average volume of air in the lungs during one cycle ?
Solution :
The volume V of air in the lungs during a five-second respiratory cycle is
Then the average volume of air in the lungs during one cycle [0,5] is
The average volume of air in the lungs during one cycle is 0.53176 liters.
