Question

The population of a suburb is 4000 people. The population of the suburb

Answer 1

Answer:

1000

Step-by-step explanation:

The population of the suburb after each decade d is given by the equation as follows :

$P=4000\times 2^d$

We need to evaluate the expression for d = -2.

Put d = -2 in the above equation. So,

$P=4000\times 2^{-2}\\\\=4000\times \dfrac{1}{2^2}\\\\=4000\times \dfrac{1}{4}\\\\=1000$

So, if d = -2, then the population of the suburb is equal to 1000.
