Options
- A19 3
- B13 19
- C19 3
- D13 19
Correct answer
A. 19 3
Step-by-step solution
Equation: 16 x²-3 y²-32 x-12 y-444=0 16 (x²-2 x )-3 (y²-4 y )=44 array l 16(x+1)²-3(y-2)²=48 (x+1)² 3 - (y-2)² 16 =1 array Centre (1,-2) bength of ransuene axis =2 a aligned Length y con jugateaxis &=2 b=2 3 e &= 1+b² a² = 1+ ( 4 3 )² = 1+16 3 e &= 19 3 aligned
