Question

4. Entomologists introduce 20 of one

variety of insect to a region and determine
that the population doubles every 6
hours.

part A Write an equation to model
this situation. Assume that the soulation
is continuously growing, and let t Represent
days.

part B What will the population be in 10 days?

part C How long will it take until the population reaches 100000?​

Answer 1

This number can be found using the Rule of 70, which describes the formula dt = 70 / r, where dt is the doubling time, and r is the annual rate of growth.

Explanation:

24/6 = 4

20 x 2 = 40 x 2 = 80 x 2 = 160 x 2 = 320

20 ---> 320 in the first day.

Keep doing this equation. Multiply each day's end result by 2 four times for 9 more days.
