Write the equation of a circle with a center (10,7) and a radius of 2

(x - 10)^2 + (y - 7)^2 = 2^2

Step-by-step explanation:

Start with the standard equation of a circle with center (h, k) and radius r:

(x - h)^2 + (y - k)^2 = r^2

Substitute 10 for h, 7 for k and 2 for r, obtaining:

(x - 10)^2 + (y - 7)^2 = 2^2

Answer

x ^2 + y^2 - 20x + 14y + 145 = 0

Step-by-step explanation:

The formula for equation of a circle is (x- h) ^2 + (y + k) ^2 = r^2

(h,k) is the center

r is the radius

Inserting the values (10,7)

h -10

k - 7

Inserting into the above formula

( x - 10)^2 + ( y + 7)^2 = 2^2

(x - 10)(x - 10) + (y + 7)(y + 7) = 4

Opening the brackets

= (x ^2 - 20x + 100) + (y^2 + 14y + 49) = 4

x^2 - 20x + 100 + y^2 + 14y + 49 = 4

Rearranging algebrally,

x^2 + y^2 - 20x + 14y + 100 + 49 - 4 = 0

= x^2 + y^2 - 20x + 14y + 145 = 0

it is a reproduction.

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
