If (x+2)^2+(y-5)^2=25 is the equation of a circle, which statement describes the circle's graph?

a) the center of the circle is (2,5), and the circle's radius is 25.

b) the center of the circle is (-2,5), and the circle's radius is 5.

c) the center of the circle is (2,-5), and the circle's radius is 5.

d) the center of the circle is (-2,-5), and the circle's radius is 5.

B

Step-by-step explanation:

The standard form of a circle is

where h and k are the coordinates of the center of the circle and the radius is squared.  The radius is easy...take the square root of 25 to get that the radius is 5.  Since the pattern for the standard form is "x-" and "y-", if (x+2)^2 is the horizontal placement of the center, it actually was originally written as (x-(-2))^2, so the h coordinate is -2.  Same goes for the vertical movement of the center.  (y-(5))^2 means that the k coordinate is a positive 5.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
