Question

Which model would best describe the population of a city if it increases in size by a factor of two every 29 years?

A)doubling time growth model

B) learning curve model

C) logistic curve model

D) half-life decay model

Answer 1

A) doubling time growth model

Explanation:

Doubling time growth model can be defined as the total or overall number of time it takes for a specific quantity to increase by doubling in value or size at a constant growth rate.

Mathematically, the doubling time growth model is given by the rule of 70;

`dt = (70)/(r)`

Where,

dt represents the doubling time.

r is the growth rate.

Hence, a doubling time growth model would best describe the population of a city if it increases in size by a factor of two every 29 years. The doubling time growth model is typically used to study or model the human population growth.
