Question 721975
Find the standard form of the equation of the hyperbola with vertices (4,1),(4,9) and foci (4,0),(4,10)
**
Given data shows hyperbola has a vertical transverse axis (y-coordinates change but x-coordinates do not)
Its standard form of equation: {{{(y-k)^2/a^2-(x-h)^2/b^2=1}}}, (h,k)=(x,y) coordinates of the center.
x-coordinate of center=4
y-coordinate of center=5 (midpoint of vertices and foci)
center: (4,5)
length of vertical transverse axis=8 (1 to 9)=2a
a=4
a^2=16
Foci:
2c=10 (0 to 10)
c=5
c^2=25
c^2=a^2+b^2
b^2=c^2-a^2=25-16=9
Equation of given hyperbola:
{{{(y-5)^2/16-(x-4)^2/9=1}}}
