Question

A population of birds that had gone extinct on a tiny island was reintroduced to that island. The generation time of these birds is 1 year. 20 birds were re-introduced to the island in 2010. In the first year after the population was re-introduced, r was 0.1. How many birds will be on the island in 2200?

Answer 1

Answer: There are 1464334099 birds in 2200.

Explanation:

Since we have given that

Number of birds were reintroduced to the island in 2010 = 20

Rate of growth r = 0.1

We need to find the number of birds will be on the islands in 2200.

Number of years in between = 2200-2010 = 190

We need to find the number of birds would be

`A=20(1+0.1)^(190)\\\\A=20(1.1)^(190)\\\\A=1464334099`

Hence, there are 1464334099 birds in 2200.
