Exponential Growth and Constant Ratios

The video tutorial explores different types of relationships in mathematics, starting with constant difference, moving to constant product, and finally focusing on constant ratio. It explains how constant ratio is used to model exponential growth, such as population increase and compound interest. The tutorial concludes with a practical exercise from a textbook to reinforce understanding.

What is the first type of relationship discussed in the video?

• Constant difference

• Constant ratio

• Exponential growth

• Constant product

How do you determine if a relationship has a constant difference?

• By dividing the values

• By multiplying the values

• By subtracting the values

• By adding the values

What is the limitation of using a constant product in relationships?

• It is only applicable to small numbers

• It cannot be used with years

• It requires division

• It always results in zero

What is the next step if constant difference and constant product do not work?

• Try a constant sum

• Try a constant subtraction

• Try a constant division

• Try a constant ratio

How is a constant ratio calculated?

• By adding two values

• By dividing two values

• By subtracting two values

• By multiplying two values

What percentage increase does a constant ratio of 1.015 represent?

• 1.05%

• 0.15%

• 15%

• 1.5%

What type of growth does a constant ratio relationship represent?

• Linear growth

• Exponential growth

• Logarithmic growth

• Quadratic growth

How does the graph of exponential growth differ from a straight line?

• It is a straight line

• It is a horizontal line

• It is a curve

• It is a zigzag

What is another application of constant ratio besides population growth?

• Compound interest

• Linear regression

• Simple interest

• Arithmetic progression

In compound interest, what happens after increasing the value by a percentage?

• The value is added to the original

• The value is ignored

• The value is subtracted

• The value is divided
