Ex 10.4 Class 11 Maths Question 7.

Vertices (±2, 0), foci (±3, 0)

Solution:
The vertices are (±2, 0) which lie on x-axis. So, the equation of the hyperbola in standard form is:

Ex 10.4 Class 11 Maths Question 8.

Vertices (0, ±5), foci (0, ±8)

Solution:
The vertices are (0, ±5) which lie on x-axis. So, the equation of the hyperbola in standard form is:

Ex 10.4 Class 11 Maths Question 9.

Vertices (0, ±3), foci (0, ±5)

Solution:
The vertices are (0, ±3) which lie on x-axis. So, the equation of the hyperbola in standard form is:

Ex 10.4 Class 11 Maths Question 10.

Foci (±5, 0), the transverse axis is of length 8.

Solution:
Here, the foci are (±5, 0) which lie on x-axis. So, the equation of the hyperbola in standard form is:

Ex 10.4 Class 11 Maths Question 11.

Foci (0, ±13), the conjugate axis is of length 24.

Solution:
Here, the foci are (0, ±13) which lie on y-axis. So, the equation of the hyperbola in standard form is:

Ex 10.4 Class 11 Maths Question 12.

Foci (±3√5, 0), the latus rectum is of length 8.

Solution:
Here, the foci are (±3√5, 0) which lie on x-axis. So, the equation of the hyperbola in standard form is:

Ex 10.4 Class 11 Maths Question 13.

Foci (±4, 0), the latus rectum is of length 12.

Solution:
Here, the foci are (±4, 0) which lie on x-axis. So, the equation of the hyperbola in standard form is:

Ex 10.4 Class 11 Maths Question 14.

Vertices (±7, 0), e = 4/3.

Solution:
Here, the vertices are (±7, 0) which lie on x-axis. So, the equation of the hyperbola in standard form is:

Ex 10.4 Class 11 Maths Question 15.

Foci (0, ±√10), passing through (2, 3).

Solution:
Here, the foci are (0, ±√10) which lie on y-axis. So, the equation of the hyperbola in standard form is:
