The volume of air in a certain runner\'s lungs (in cubiccentimeters) is modeled

Question

The volume of air in a certain runner's lungs (in cubiccentimeters) is modeled by the equation: V= 350 sin (66t) + 1000 where t is the time inminutes. Find the maximum volume of air in the runner's lungs, and howdetermine how many breaths teh runner takes per minute. The maximum volume is --------- cm3 The volume of air in a certain runner's lungs (in cubiccentimeters) is modeled by the equation: V= 350 sin (66t) + 1000 where t is the time inminutes.

Explanation / Answer

The period of a Sine function in the form ofAsin(Bx+C) is 2/B, which in this case is 66giving you 1/33 as your period,

P=1/F gives you the frequency of 33.
