a) The Linear function will be:
b) After 50 months, the length will be 40 inches.
Step-by-step explanation:
In this question we need to find the linear function to model length L(t). We are given:
Length of hair to donate = 15 in
Growth of hair per month = 1/2 in
The Linear function will be:
- Now, determining the time t when her hair length reaches 40 inches.
Length of hair L(t) = 40
We need to find t in the above linear function
Subtracting 15 from both sides
Multiplying 2 on both sides
So, After 50 months, the length will be 40 inches.
