Which equation represents a circle that contains the point (–5, –3) and has a center at (–2, 1)? distance formula: (x – 1)2 + (y + 2)2 = 25 (x + 2)2 + (y – 1)2 = 5 (x + 2)2 + (y – 1)2 = 25 (x – 1)2 + (y + 2)2 = 5

Option 3 -  

Step-by-step explanation:

Given : A circle that contains the point (-5,-3) and a center at (-2,1).

To find : Which equation represents a circle ?

Solution :

The general equation of the circle in center radius form is

where, r is the radius

(h,k) is the center of the circle.

We know, the distance between the center and any point that lie on the circle is equal to the radius of the circle.

Now, the distance between two points is given by

Here, and

The radius of the circle is 5 units.

Substitute all the values in the general formula,

Therefore, Option 3 is correct.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
