## anonymous one year ago Write the equation of a hyperbola with vertices at (-3, 0) and (3, 0) and co-vertices (0, 5) and (0, -5).

hint: the vertices of a hyperbola are these points: |dw:1439650842685:dw|

2. anonymous

okay but where do the co vertices come from?

3. Michele_Laino

the co-vertices are these points: |dw:1439650986535:dw|

4. anonymous

ohh! okay

5. Michele_Laino

in other words, our hyperbola can be represented by the subsequent equation: $\Large \frac{{{x^2}}}{{{a^2}}} - \frac{{{y^2}}}{{{b^2}}} = 1$ where: $\Large a = 3,\quad b = 5$

x2/9-y2/25 is the awnser?

7. Michele_Laino

correct!
