Final answer:

The given hyperbola's foci are at approximately (±5.385, 0), vertices and endpoints of transverse axis at (±5, 0), and endpoints of conjugate axis at (0, ±2). The length of the latus rectum is 8/5, and the directrices are vertical lines at x ≈ ±4.618.

Step-by-step explanation:

The equation of the hyperbola (x²/25) - (y²/4) = 1 indicates that its center is at (0,0), with a² = 25 and b² = 4. The vertices are at (±5,0), and the foci are located at (±c,0) where c² = a² + b² = 29, hence c ≈ ±5.385. The endpoints of the transverse axis are the vertices, and those of the conjugate axis are at (0, ±2). Length of the latus rectum is 2b²/a = 8/5. The hyperbola opens sideways since is under . The directrices are vertical lines at x = ±a/e ≈ ±4.618, where e = c/a.
