Question

what is a doubling time? suppose a population has a doubling time of 30 years. by what factor will it grow in 120 years?

choose the correct definition of a doubling time below.
a. the time required for each doubling in exponential growth.
b. the time required for each halving in exponential growth.
c. the time required for each doubling in linear growth.
d. the time required for each halving in linear growth.

by what factor will population grow in 120 years?
(type exponential notation with positive exponents.)

Explanation:

Define doubling time

Using the Doubling Time and Exponential Growth knowledge points

$$ \text{Doubling time is the time required for each doubling in exponential growth.} $$

Answer:

Question 1

• A. The time required for each doubling in exponential growth. (Correct answer)
• B. The time required for each halving in exponential growth.
• C. The time required for each doubling in linear growth.
• D. The time required for each halving in linear growth.

Question 2
