Answer:
Maximum heart rate can be represented into a function as follows
let
x = age
y = Maximum heart rate
equation will be
y =220-x
for example if we take a person who is 50 years old then the maximum heart rate that person will have will be
y= 220 - 50
y = 170
This means that this is the average maximum number of times your heart should beat per minute while exercising.
Step-by-step explanation:
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
