Use the following formulas to answer the questions below: T(M,R)=R+0.6(M-R) M(x)= 220-x where R= resting heart rate, M= maximum heart rate, and x= age Recall our discussion of heart rate and composition of functions from the end of the section?

Question

T(M)for a person with a resting heart rate of 60 beats per minute, then find the following.
a).Find the maximum heart rate function, M(x) for a person x years of age.
M(x)=
b). What is the maximum heart rate for a 29-year-old person?
The max heart rate for a 29−year-old person is _ beats per minute.
c). What is the training heart rate for a 29-year-old person with a resting heart rate of 60 beats per minute?
The training heart rate for a 29-year-old person with a resting heart rate of 60 beats per minute is _ beats per minute.
d).What is the training heart rate for a 36-year-old person with a resting heart rate of 60 beats per minute?

a) M(x)=220-x
x = your age

b) x=29
220-29=191

c) R=60
60+0.6(191-60)=138.6

d) x=36, R=60
T=60+.6(220-36-60)=134.4

Commas are important. :-)
T(M,R)=R+0.6(M-R); M(x)= 220-x
T=R+.6(220-x-R)
