The distance between (x1,y1)(x_1,y_1)(x1,y1) and (x2,y2)(x_2,y_2)(x2,y2) is [...]\text{[...]}[...].
A
The distance between (x1,y1)(x_1,y_1)(x1,y1) and (x2,y2)(x_2,y_2)(x2,y2) is d=(x2−x1)2+(y2−y1)2\boxed{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}d=(x2−x1)2+(y2−y1)2.
B
(x−2)2+(y+3)2=100(x-2)^2+(y+3)^2=100(x−2)2+(y+3)2=100
C
x2+y2=49x^2+y^2=49x2+y2=49
D
CPCPCP is the radius, rrr.
