Question

The length of a string in yards is a function f(n) of the length n in inches. Write a function rule for this situation.
A) f(n) = 36n
B) f(n) = n/12
C) f(n) = 12n
D) f(n) = 1/36n

Answer 1

The foot is a unit of length used in the stately and U.S. usual dimension systems, signifying 1/3 of a yard, and is divided into twelve inches. Then, when we convert 1 yard to inches, it will be 36 inches. So therefore, the answer is the right function rule is f (n) = 1/36n.

Answer 2

Answer: D

Explanation:

F(n)= 1/36n
