Exponential Growth: How Random Acts of Kindness Spread

The video tutorial explains how random acts of kindness can spread using an exponential growth model. It begins with an introduction to the concept, followed by an explanation of exponential growth using bacteria as an example. The tutorial then applies this model to a kindness experiment, where each person compliments three others, leading to rapid growth in the number of compliments. Finally, it discusses predicting future growth using exponential formulas, emphasizing the importance of each participant continuing the chain for sustained growth.

What is the initial action taken in the random acts of kindness experiment?

• Each person compliments four others.

• Each person compliments three others.

• Each person compliments two others.

• Each person compliments one other.

Which of the following is an example of exponential growth?

• A person saving a fixed amount of money monthly.

• A population doubling every year.

• A plant growing at a constant rate.

• A car accelerating at a steady speed.

What is the equal factor used in tripling?

• 3

• 5

• 2

• 4

How many people are complimented on day 4 in the kindness experiment?

• 54

• 27

• 81

• 108

What happens if one person does not continue the compliment chain?

• The growth rate remains the same.

• The growth rate increases.

• The growth rate doubles.

• The growth rate slows down.
