Answer:
where R is the R-value and t is the thickness in inches.
Step-by-step explanation:
We are given the following in the question:
The R-value of fiberglass insulation and f its thickness have a linear relation.
Let R be the R-value and t be the thickness. Then, the equation can be written as:
where a and b are constants.
When t = 3.5, R = 11
When t = 6, R = 19
Solving the two equation, using the elimination method, we have,
Thus, the linear relationship is given by:
where R is the R-value and t is the thickness in inches.
