During exercise, the recommended maximum heart rate in beats per minute is modeled by the formula m = 176 − 0.8a, where m is the maximum heart rate and a is the person’s age. solve the formula for a. at what age would you have a recommended maximum heart rate in beats per minute of 135? 25 years 39 years 51 years 53 years

51 years

Step-by-step explanation:

Given : During exercise, the recommended maximum heart rate in beats per minute is modeled by the formula :

, where M is the maximum heart rate and A is the person’s age.

To solve  the formula for A , add 0.8A and subtract M on both sides , we get

Divide 0.8 on both sides , we get

i.e. Formula for A :

Put M=  135, we get

Hence, at the age of 51 years you would have a recommended maximum heart rate in beats per minute of 135.
