Write an equation to calculate population density at time t+1 .

How is population density calculated?

The population of a town increases at a rate proportional to the population at that time . If the population increases from 40 thousands to 60 thousands in 40 years, What will be the population in another 20 years ? = [ Given: sqrt(3/2) = 1.2247 ]

Write definitions of the following: Population Density

The rate of growth of the population of a city at any time t is proportional to the size of the population. For a certain city it is found that the constant of proportionality is 0.04. Find the population of the city after 25 years if the initial population is 10,000. [take, e =2.7182] .

A TV tower has a height of 200 M. How much population is covered by TV transmission if the average population density around the tower is 1000//km^2 ?

Write a short note on population interaction .

Write one solution of the equation 2x-y+1=0 .
