To find: Population of bats one year ago.
Answer to Problem 112RE
Population of species of bat one year ago was
Explanation of Solution
Given:
Exponential decay model
Consider an exponential decay model
Where B is the number of species of bat at present,
Before 5 years
Implies
Hence
Before 2 years
Implies
Hence
Divide equation (2) by equation (1)
Applying natural logarithm on both sides
Substituting the value of k in equation (1)
Therefore, the model is
Hence, one year ago
Hence, population of species of bat one year ago was
