Find the length of transverse axis of the hyperbola 
.
Choices:
A. y = 0
B. y = 5
C. x = 0
D. x = 2
Correct Answer: D
Solution:
Step 1: 
[Equation of hyperbola.]
Step 2: 
[Divide both sides by 100.]
Step 3: This is in the standard form 
of a hyperbola whose transverse axis is y - axis, where 
= 4 and 
= 25.
Step 4: a = 2 and b = 5 [Solve for a, b.]
Step 5: So, the length of the transverse axis of the hyperbola is 2a = 2(2) = 4.
