Question 22 (2 points)

What is the radius and the center of the circle?

(x - 3)2 + (y + 2)2 = 16

Radius = 4, Center = (3,-2)

Radius = 4, Center = (3, 2)

Radius = 8, Center = (3,-2)

Radius = 8, Center = (3, 2)

mm

Radius = 4, Center = (3,-2)

Step-by-step explanation:

The equation of a circle has the following format:

In which r is the radius(half the diameter) and the centre is the point

In this question, we have that:

So the center is (3,-2) and the radius is

So the correct answer is:

Radius = 4, Center = (3,-2)

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:

for future students the answer is b
