Dog Age to Human Age Conversion

The video tutorial explains how to use the equation y = 16 * ln(x) + 31 to convert a dog's age to human years. It walks through the process of calculating the human age for a 4-year-old dog using a calculator, demonstrating each step and emphasizing the importance of rounding the result to the nearest tenth. The tutorial concludes by confirming that a 4-year-old dog is approximately 53.2 years old in human years.

What is the equation used to convert a dog's age to a human's age?

• y = 31 * ln(x) + 16

• y = 16 * x + 31

• y = 16 * ln(x) + 31

• y = ln(x) + 31
