the heart rate of a person can be modeled by he function R(a) is heartbeats per minute the life span in minutes of a person is modeled by the function S(a) =525600a

explain what (r*s)(a)
Responses
the heart rate of a person who is a years old

the total number of heartbeats in a lifetime of a person who is a years old

the total number of heartbeats in a lifetime of a person who is a minutes old

the heart rate of a person who is a minutes old

The correct response is:

the total number of heartbeats in a lifetime of a person who is a years old

To calculate (r*s)(a), you would multiply the heart rate function R(a) by the lifespan function S(a), which gives you the total number of heartbeats in the lifetime of a person who is a years old.
