Questions
a
(x−2)2+(y−3)2=4
b
(x+1)2+(y−2)2=4
c
(x−3)2+(y−2)2=4
d
(3x+2)2+(3y−2)2=400
detailed solution
Correct option is D
Given point A(1,−1) and B lies on x2+y2=16 . Let point B be (x,y) and point P be (h,k) . ∴ (x,y)=3h+25,3k−25 Now B lies on x2+y2=16∴ 3h+252+3k−252=16∴ (3x+2)2+(3y−2)2=400, which is required locus.Talk to our academic expert!
