It is known that the eccentricity of hyperbola x2a2-y2b2 = 1 is 2, and the focus is the same as that of ellipse X225 + Y29 = 1, then the focus coordinates and asymptote equations of hyperbola are () A. (±4,0),y=±33xB. (±4,0),y=±3xC. (±2,0),y=±33xD. (±2,0),y=±3x

The focus of ∵ ellipse X225 + Y29 = 1 is (4, 0) (- 4, 0), so the eccentricity of C = 4, ∵ hyperbola x2a2-y2b2 = 1 is 2, ∵ CA = 2, ∵ a = 2, ∵ B = C2 − A2 = 23, ∵ asymptote equation of hyperbola is y = ± Bax, that is y = ± 3x
