Find the eccentricity of the hyperbola x²/16 − y²/9 = 1.
Answer and explanation
Correct answer: D.
- Step 1: For a hyperbola c² = a² + b² = 16 + 9 = 25, so c = 5. Step 2. e = c/a = 5/4. **Answer: . Why not the others:** is what you get if you invert e. is what you get if you use c/b. is what you get if you use b/a.
