HELP PLEASE
THE POPULATOPM OF A SUBURB IS 4000 PEOPLE.THE POPULATION OF THE SUBURB IS EXPECTED TO DOUBLE EACH DECADE.THE EXPRESSION 4000 * 2^d models the population of the suburb after each decade d.Evaluate the expression for d=-2.Describe what the value of the expression represents in this situation

Answer 1

The equation \[4000 \times 2^{2}\]
would represent the population 20 years from now, so the equation
\[4000 \times 2^{-2}\] would represent the population 20 years /ago/.

thus, you are dividing the population in half, twice.

Answer 2

SO THE ANSWER IS 1000?

Answer 3

Yes
