Question

For this discussion forum, please choose any country in the world (other than the USA) and research it's current population and it's population growth rate. Use this information and the exponential growth model discussed this week to predict the population of your country in the year 2050.

Also find one interesting fact about your country, and share your mathematics and interesting fact. The answer must be typed!

The formula we are using is

Exponential growth is any increase in a quantity P.

     P(t)= Poe^(kt)

Where Po is the initial quantity, t is time, k is a constant, P(t) is the quantity after time t, and e^x is the exponential function.

Answer 1

let's talk about India

The current population of India is P₀=1,376,937,200 as of Friday, April 10, 2020

and the current population growth rate is r=0.99% = 0.0099

P₀=1376937200

r=0.99% = 0.0099

to predict the population in the year 2050, take t=2050-2020 = 30

................population in 2050

and one interesting fact is:

Indian housewives hold 11% of the world's gold.

That is more than the reserves of the USA, the IMF, Switzerland, and Germany put together!
