Q. A hyperbola centered at the origin has vertices at (0,±54) and foci at (0,±89).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 given at (0,±54), so a=54.
Calculating a2: Calculate the value of a2.a2=(54)2=54.
Finding the semi-minor axis: Find the value of the semi-minor axis b. The relationship between the semi-major axis a, the semi-minor axis b, and the distance to the foci c for a hyperbola is c2=a2+b2.
Calculating c: Calculate the value of c using the coordinates of the foci. The foci are given at (0,±89), so c=89.
Calculating c2: Calculate the value of c2.c2=(89)2=89.
Using c2 to find b2: Use the relationship c2=a2+b2 to find b2. Substitute the known values of a2 and c2 into the equation. 89=54+b2b2=89−54b2=35
Writing the equation in standard form: Write the equation of the hyperbola in standard form after substituting the values of h, k, a2, and b2. Substitute h=0, k=0, a2=54, and b2=35 into (y−k)2/a2−(x−h)2/b2=1. (y−0)2/54−(x−0)2/35=1k0
