FLASHCARD QUESTION
Front
What is exponential decay?
Back
Exponential decay occurs when a quantity decreases by a constant percentage over time, leading to a rapid decrease. For example, if a population decreases by 5% each year, it will decline faster each subsequent year.

FLASHCARD QUESTION
Front
What is the general formula for exponential growth?
Back
The general formula for exponential growth is y = a(1 + r)^t, where 'a' is the initial amount, 'r' is the growth rate, and 't' is time.

What is the general formula for exponential decay?
Back
The general formula for exponential decay is y = a(1 - r)^t, where 'a' is the initial amount, 'r' is the decay rate, and 't' is time.

FLASHCARD QUESTION
Front
What is the effect of a 10% decay rate on a population of 1000 after 1 year?
Back
After 1 year, the population would be 1000(1 - 0.10) = 900.

FLASHCARD QUESTION
Front
If a population of 500 decreases by 4% each year, what will be the population after 3 years?
Back
Population after 3 years = 500(1 - 0.04)^3 ≈ 500(0.864) ≈ 432.
