Question 444614
Maximum Heart Rate When exercising, people
often try to maintain target heart rates that are a percentage
of their maximum heart rate. Maximum heart
rate R is R=220-A  where A is the person’s age
and R is the heart rate in beats per minute.
------------------------
(a) Find R for a person 20 years old and R for 70 years old.
R(20) = 220-20 = 200
------------------------------------
(b) Sketch a graph of Assume that A
is between 20 and 70 and put A on the horizontal
axis of your graph.
{{{graph(400,300,20,70,-10,230,220-x)}}}
--------
(c) Interpret your graph.
I'll leave that to you.
