An animal reserve 24,000 elk. The population is increasing at a rate of 13 percent per year. How long will it take for the population to reach 72,000?If necessary, round your answer to the nearest tenth. The population will reach 72,000 in approximately years

  9.0 years

Step-by-step explanation:

The exponential equation for the population can be written as ...

  population = (initial population)(1 +growth rate)^t

  p = 24000(1.13^t)

We want this to be 72000, so ...

  72000 = 24000(1.13^t)

Dividing by 24000 gives ...

  3 = 1.13^t

Taking logs, we have ...

  log(3) = t·log(1.13)

  log(3)/log(1.13) = t ≈ 8.98

It will take about 9.0 years for the elk population to reach 72,000.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
