Number of intersecting points of the conics \(4 x^{2}+9 y^{2}=1\) and \(4 x^{2}+y^{2}=4\) is
- A 1
- B 2
- C 3
- D 0
Answer & Solution
Correct Answer
(D) 0
Step-by-step Solution
Detailed explanation
For curve I. \(4 x^{2}+9 y^{2}=1 \Rightarrow \frac{x^{2}}{\left(\frac{1}{2}\right)^{2}}+\frac{y^{2}}{\left(\frac{1}{3}\right)^{2}}=1\) which is an equation of ellipee with \(a=\frac{1}{2}\) and \(b=\frac{1}{3}\) For curve \(I I, 4 x^{2}+y^{2}=4\)…
