Question 1153740: Write an equation of a hyperbola with the given foci and vertices
Foci (+-5,0), vertices (+-3,0)

given:
foci (5,0), (5,0)
vertices (3,0), (-3,0)
We can tell that it is a horizontal hyperbola.
The center point is (0, 0).
To find a, we'll count from the center to either vertex.
a+=+3
To find c, we'll count from the center to either focus.
c+=+5
then use
c%5E2+=+a%5E2+%2B+b%5E2
b%5E2+=+c%5E2+-a%5E2
b%5E2+=+5%5E2+-3%5E2
b%5E2+=+25+-9
b%5E2+=+16
+b=4

We have all our information:+h+=+0, k+=+0, a+=+3, b+=+4. Since it's a horizontal hyperbola centered in origin, we'll choose that formula and substitute in our information.

x%5E2%2F9-y%5E2%2F16=1
