  1. A \(9 x^2-4 y^2=36\)
  2. B \(2 x^2-3 y^2=7\)
  3. C \(x^2-y^2=16\)

Verified Solution

Answer & Solution

Correct Answer

(D) \(x^2-y^2=32\)

Step-by-step Solution

Detailed explanation

Let the equation of hyperbola be \(\frac{x^2}{a^2}-\frac{y^2}{b^2}=1\) We have, \(e=\sqrt{2} \text { and } 2 a e=16 \Rightarrow 2 a(\sqrt{2})=16\) \(\Rightarrow \quad a=\frac{16}{2 \sqrt{2}}=4 \sqrt{2}\) \(\therefore\) Equation of hyperbola is…
