FLASHCARD QUESTION
Front

Exponential growth occurs when the increase in a quantity is proportional to its current value, leading to growth at an increasing rate. For example, if a population grows by 10% each year, it grows faster each year as the base number increases.

What is exponential decay?
Back
Exponential decay is the decrease in a quantity at a rate proportional to its current value, leading to a rapid decline. For example, radioactive substances decay at a rate proportional to their current amount.

FLASHCARD QUESTION
Front
What is the formula for exponential growth?
Back
The formula for exponential growth is A = P(1 + r)^t, where A is the amount after time t, P is the initial amount, r is the growth rate, and t is time.

What is the formula for exponential decay?
Back
The formula for exponential decay is A = P(1 - r)^t, where A is the amount after time t, P is the initial amount, r is the decay rate, and t is time.

FLASHCARD QUESTION
Front
How do you find the decay rate from a decay model?
Back
In a decay model of the form A = P(1 - r)^t, the decay rate r can be found by identifying the coefficient of the exponential term.

FLASHCARD QUESTION
Front
If a population of 1000 decreases by 20% each year, what is the population after 3 years?
Back
Using the formula A = P(1 - r)^t, A = 1000(1 - 0.20)^3 = 1000(0.8)^3 = 512.

FLASHCARD QUESTION
Front
What does a decay factor of 0.85 indicate?
Back
A decay factor of 0.85 indicates that the quantity retains 85% of its value after each time period, meaning it decreases by 15%.
