Q. A hyperbola centered at the origin has vertices at (0,±6) and foci at (0,±74).Write the equation of this hyperbola.
Standard Form of Hyperbola Equation: Identify the standard form of the equation for a hyperbola with a vertical transverse axis.Standard form of equation for a hyperbola with a vertical transverse axis: (y−k)2/a2−(x−h)2/b2=1
Determining the Center: Determine the center (h,k) of the hyperbola. Since the hyperbola is centered at the origin, h=0 and k=0.
Finding the Semi-Major Axis: Find the value of the semi-major axis a. The vertices are at (0,±6), so a=6.
Calculating the Distance to the Foci: Calculate the distance c between the center and the foci. The foci are at (0,±74), so c=74.
Using the Relationship between a, b, and c: Use the relationship c2=a2+b2 to find the value of b. Substitute the known values of a and c into the equation. c2=a2+b2742=62+b274=6+b2b2=74−6b2=68b=68
Writing the Equation in Standard Form: Write the equation of the hyperbola in standard form after substituting the values of h, k, a, and b. Substitute values of h, k, a, and b into (y−k)2/a2−(x−h)2/b2=1. (y−0)2/(6)2−(x−0)2/(68)2=1k0
