In the standard equation (x−h)2a2−(y−k)2b2=1\(\frac{(x-h)^2}{a^2}\)-\(\frac{(y-k)^2}{b^2}\)=1, what point is the center of the hyperbola?
A hyperbola is centered at the origin, opens left and right, has vertices at (±4,0)(±4, 0), and its fundamental rectangle reaches y=±3y = ±3. What is its equation?
A researcher selects two points on the same hyperbola and measures their distances to the two foci. For the first point, the distances are 1313 and 55. For the second point, the distances are 2020 and 1212. What is the best conclusion?
