Question

Standard form of the circle with a center is (9, 1) tangent to the x-axis

Answer 1

Answer:

(x-9)²+(y-1)²=1

Step-by-step explanation:

Standard equation of a circle with center at (h, k) and radius r

(x-h)²+(y-k)²=r²

(x-9)²+(y-1)²=r², for the center of the circle at (9,1)

(x-9)²+(y-1)²=1², because the radius must be 1 since the circle needs to tangent to the x-axis

(x-9)²+(y-1)²=1
