  1. A \(\left( { - 6 , 2\sqrt {10} } \right)\)
  2. B \(\left( {2\sqrt 6 , 5} \right)\)
  3. C \(\left( { 4 , \sqrt {15} } \right)\)
  4. D \(\left( { 6 , 5\sqrt {2} } \right)\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(\left( { 6 , 5\sqrt {2} } \right)\)

Step-by-step Solution

Detailed explanation

equation of hyperbola is \(\frac{{{x^2}}}{4} - \frac{{{y^2}}}{{{b^2}}} = 1\) and \(ae = 3\) We know that \({a^2}{e^2} = {a^2} + {b^2}\) \(9 = 4 + {b^2} \Rightarrow {b^2} = 5\) Hence equation of hyperbola is \(\frac{{{x^2}}}{4} - \frac{{{y^2}}}{5} = 1\,\) Hence…
