Q. A hyperbola centered at the origin has vertices at (±45,0) and foci at (±70,0).Write the equation of this hyperbola.
Identify Equation Form: Identify the standard form of the equation for a hyperbola centered at the origin with horizontal transverse axis.Standard form of equation for a hyperbola with horizontal transverse axis: (a2x2)−(b2y2)=1
Determine a and a2: Determine the values of a and a2. The vertices are at (±45,0), so a=45 and a2=45.
Determine c and c2: Determine the values of c and c2. The foci are at (±70,0), so c=70 and c2=70.
Find b2: Use the relationship c2=a2+b2 to find b2. Substitute the known values of a2 and c2 into the equation. 70=45+b2b2=70−45b2=25
Write Standard Form Equation: Write the equation of the hyperbola in standard form using the values of a2 and b2. Substitute a2=45 and b2=25 into the standard form equation (x2/a2)−(y2/b2)=1. (x2/45)−(y2/25)=1
