To state: The life span of a cat with a heart rate of
The table shows about how the life span s of a mammal relates to its heart rate r .
Mammal | Heart rate (beats/min) | Life span (min) |
Mouse | 634 | 1,576,800 |
Rabbit | 158 | 6,307,200 |
Lion | 76 | 13140,000 |
The life span of a cat is about 15.2 years.
Given information:
The given table is:
Mammal | Heart rate (beats/min) | Life span (min) |
Mouse | 634 | 1,576,800 |
Rabbit | 158 | 6,307,200 |
Lion | 76 | 13140,000 |
Explanation:
The data can be modeled by an equation:
Now consider the product of the variables
Mouse:
Rabbit:
Lion:
Thus,
Therefore, the constant in inverse variation is
Now find the life span of a cat with heart rate of
