Using a geometric growth model to predict population growth, a population of 10 individuals at time zero with a finite growth ra
Grace [21]

Answer: Option E, in 12 years.

Explanation:

A geometric growth model is characterized by its finite growth rate, known as lambda. The size of the population after a unit of time has passed can be calculated using the last known size and lamba as:

N_{t+1} = \lambda * N_t

Starting from the initial value of population, the next one will be calculated multiplying by 1.4, and the next one multiplying again by 1.4, thus we can define a function that relates the time passed in year to the size of the population:

N(t) = \lambda^{t} *N_0

Substituting our values we get the function that defines the growth of our poupulation:

N(t) = 1.4^{t} *10

Then, we just have to clear the t that gives a population of 500:

500 =  1.4^t*10, divide\ both\ sides\ by\ 10\\50 = 1.4^t, apply\ log_{1.4}(x)\ to\ both\ sides\\log_{1.4}(50)=t\\11.63=t

Thus, at 12 years, the population will be greater than 500.
