Atown has a population of 8000 in groves at 4.5% every year to the nearest year how long will it be until the population will reach 22,500

It takes 10 years approximately for the population to reach 22,500

Step-by-step explanation:

Given:

Initial population  =  8000

Population growth rate  4.5 %

Future population = 22500

To Find:

Time taken to reach a population of  22500

Solution:

The population growth can be identified by using

where

N is  future popluation

is the initial population

t is the time taken

r is the rate of the growth

Here we have to find the time t, rephrasing the formula

Substituting the values we get,

t = 9.97

t=10(approx)

  105 m

Step-by-step explanation:

  distance/time = (63 m)/(3 s) = d/(5 s)

Multiplying by (5 s) gives the distance d as ...

  d = (5 s)(63 m)/(3 s) = 105 m

An ostrich can run 105 m in 5 seconds.
