This is exponential growth and decay

Given:

In 1999, the number of mosquitos = 2500

They tripled every year.

To find:

The model for this situation and find the number of mosquitos in 2005.

Solution:

The general exponential modal is

         ...(i)

Where, a is the initial value and 0<b<1 is decay factor and b>1 is growth factor.

In 1999, the number of mosquitos is 2500.

Initial value:

They tripled every year. So, growth factor is 3>1 and it is exponential growth.

Growth factor:

Putting and in (i), we get

          ...(ii)

Here, y is the population of mosquitos after x year of 1999.

Therefore, the required exponential growth modal is .

We know that,

Putting x=6 in (ii), we get

Therefore, the estimated number of mosquitos in 2005 is 1822500.

think about it deeply and passionately about this property

i am sorry

it would more likely be bald eagle because its has more in the box so about 75%.
