Question 739678: Write the standard equation for each Hyperbola.
1. x2 - 100y2 = 100
2. 4y2 - 25x2 = 100
3. vertices (-6, 0) ( 6, 0) and
focus (-8, 0) ( 8, 0)
4. vertices ( 0, -12) ( 0, 12) and
co-vertices (-11, 0) (11, 0)

You can put this solution on YOUR website! Write the standard equation for each Hyperbola.
1. x^2 - 100y^2 = 100
Equation: 
..
2. 4y^2 - 25x^2 = 100
Equation: 
..
3. vertices (-6, 0) ( 6, 0) and
focus (-8, 0) ( 8, 0)
center:(0,0)
a=6
a^2=36
c=8
c^2=64
b^2=c^2-a^2=64-36=28
Equation: 
..
4. vertices ( 0, -12) ( 0, 12) and
co-vertices (-11, 0) (11, 0)
center:(0,0)
a=12
a^2=144
b=11
b^2=121
Equation:
