Given equation of hyperbola is49y2 – 16x2 = 784
In each of the Exercises 7 to 15, find the equations of the hyperbola satisfying the given conditions.
Ex 11.4 Class 11 Maths Question 7.
Vertices (±2,0), foci (±3,0)
Solution:
Vertices are (±2, 0) which lie on x-axis. So the equation of hyperbola in standard form
Ex 11.4 Class 11 Maths Question 8.
Vertices (0, ±5), foci (0, ±8)
Solution:
Vertices are (0, ±5) which lie on x-axis. So the equation of hyperbola in standard form
Ex 11.4 Class 11 Maths Question 9.
Vertices (0, ±3), foci (0, ±5)
Solution:
Vertices are (0, ±3) which lie on x-axis. So the equation of hyperbola in standard form
Ex 11.4 Class 11 Maths Question 10.
Foci (±5, 0), the transverse axis is of length 8.
Solution:
Here foci are (±5, 0) which lie on x-axis. So the equation of the hyperbola in standard
Ex 11.4 Class 11 Maths Question 11.
Foci (0, ±13), the conjugate axis is of length 24.
Solution:
Here foci are (0, ±13) which lie on y-axis.
So the equation of hyperbola in standard
Ex 11.4 Class 11 Maths Question 12.
Foci (\(\pm 3\sqrt { 5 } \),0) , the latus rectum is of length 8.
Solution:
Here foci are (\(\pm 3\sqrt { 5 } \), 0) which lie on x-axis.
So the equation of the hyperbola in standard
Ex 11.4 Class 11 Maths Question 13.
Foci (±4, 0), the latus rectum is of length 12.
Solution:
Here foci are (±4, 0) which lie on x-axis.
So the equation of the hyperbola in standard
Ex 11.4 Class 11 Maths Question 14.
Vertices (+7, 0), e = \(\frac { 4 }{ 3 } \)
Solution:
Here vertices are (±7, 0) which lie on x-axis.
So, the equation of hyperbola in standard
Ex 11.4 Class 11 Maths Question 15.
Foci (0, \(\pm \sqrt { 10 } \)), passing through (2, 3).
Solution:
Here foci are (0, \(\pm \sqrt { 10 } \)) which lie on y-axis.
So the equation of hyperbola in standard form
