1. Pia drew a circle with a circumference of C and a diameter of 14 in. Pia knows that C = id, and she wrote the following equation to represent the value of n.
14
C
(a) There is an error in Pia's equation. Write an equation to correctly represent the value of it. Show
=
your work
(b) Write an equation and find the circumference of the circle.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

thus, the first answer choice, y = sec x, is the correct one
