Q. Maya shaved her head and then began letting her hair grow. She represents the length ℓ of her hair, in centimeters, m months after she shaved her head using the equation ℓ=1.25m.What does 1.25 mean in this situation?Choose 1 answer:A) It has been 1.25 months since Maya shaved her head.(B) Maya's hair grows 1.25 centimeters per month.(C) Maya's hair takes 1.25 months to grow a centimeter longer.
Equation Explanation: The equation given is ℓ=1.25m, which shows the relationship between the length of Maya's hair (ℓ) and the time in months (m) since she shaved her head.
Unit Analysis: To understand what 1.25 means, we need to look at the units. Since ℓ is in centimeters and m is in months, 1.25 is the rate at which Maya's hair grows in centimeters per month.
Interpretation of Growth Rate: So, 1.25 is not the time since Maya shaved her head, and it's not the time it takes for her hair to grow a centimeter. It's the growth rate of her hair per month.
