Q. Asymptotes y=±45x one vertex is (0,3) what is equation of hyperbola
Identify Conic Section: Identify the type of conic section based on the given asymptotes and vertex. The asymptotes y=±45x suggest a hyperbola centered at the origin, and the vertex at (0,3) indicates a vertical hyperbola.
Standard Form: Use the standard form of a vertical hyperbola centered at the origin, which is y−k)2/a2−(x−h)2/b2=1where$h,k is the center and 'a' is the distance from the center to each vertex along the y-axis.
Center and 'a': Since the vertex given is (0,3), and it's a vertical hyperbola, the center is at (0,0) and 'a' is 3. This is because the vertex is 3 units away from the center along the y-axis.
Solve for 'b': The slopes of the asymptotes for a vertical hyperbola are given by ±ba. We know the slopes are ±45, so setting ba=45 and knowing a=3, solve for 'b'. ba=45b3=45b=3×54b=512 or 2.4
Plug Values into Equation: Plug the values of a and b into the standard form equation of the hyperbola. (y−0)2/32−(x−0)2/(12/5)2=1y2/9−x2/(2.88)=1
