Find the equation of the circle of radius 5 units and concentric with the circles x2 + y2 - 6x + 4y + 12 = 0.

Step-by-step explanation:

x² + y² - 6x + 4y + 12 = 0

(x - 3)² + (y + 2)² = 1

Hence the equation of the concentric circle is (x - 3)² + (y + 2)² = 25.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
