A) One point
B) Three points
C) Two points
D) Four points
Correct Answer: D
Solution :
A = Set of all values (x, y) : \[{{x}^{2}}+{{y}^{2}}=25={{5}^{2}}\] B = \[\frac{{{x}^{2}}}{144}+\frac{{{y}^{2}}}{16}=1\] i.e., \[\frac{{{x}^{2}}}{{{(12)}^{2}}}\] + \[\frac{{{y}^{2}}}{{{(4)}^{2}}}=1\]. Clearly, A Ç B consists of four points.You need to login to perform this action.
