A bird species in danger of extinction has a population that is decreasing exponentially

Five years ago the population was at 1400 and today only 1000 of the birds are alive. Once the population drops below 100, the situation will be irreversible. When will this happen?

The population of birds vary as

Given that population of brds fell from 1400 to 1000,we are asked how much time it will ake forthe population to fall below 100 when t=5

we can write the following equation

we need to find x,such that

in (14)=kx

It will take 39 years for the population f birds to fall below 100
