The initial population of a town is 2600, and it grows with a doubling time of 10 years. Determine how long it will take for the population to quadruple. It will take the population years to quadruple.
(Round to the nearest whole number as needed.)

It will take the 20 years for the population to quadruple.

Step-by-step explanation:

Exponential population growth:

An exponential model for population growth has the following model:

In which P(0) is the initial population and r is the growth rate, as a decimal.

It grows with a doubling time of 10 years.

This means that . We use this to find r. So

So

Determine how long it will take for the population to quadruple.

This is t for which P(t) = 4P(0). So

It will take the 20 years for the population to quadruple.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

you already gave the answer
