What is conjugate axis length for hyperbola \((\frac{x}{9})^2-(\frac{y}{16})^2\)=1?(a) 5 units(b) 4 units(c) 8 units(d) 10 unitsI have been asked this question in exam.This question is from Conic Sections in division Conic Sections of Mathematics – Class 11

Answer»

Right choice is (c) 8 UNITS

Easy explanation: COMPARING the equation with \((\frac{x}{a})^2-(\frac{y}{b})^2\)=1, we get a=3 and b=4.

Conjugate AXIS length = 2b = 2*4 =8 units.
