**Problem:**

Find the equation of a parabola that has its vertex at the origin and satisfies the following conditions:

(a) Focus: F(5, 0)

(b) Directrix: y = -5

(c) Directrix has x-intercept 5

**Explanation:**

This problem asks for the equation of a parabola with specific characteristics. The vertex is at the origin (0,0), and the focus is at point F(5,0), indicating the parabola opens horizontally. The directrix is given as y = -5; however, the mention of an x-intercept being 5 suggests checking for consistency in problem constraints.

**Additional Notes:**

- The typical equation format for a parabola with a horizontal axis of symmetry (opening right or left) is \( x = ay^2 + by + c \).
- Focus and directrix properties can be used to find the correct value of the parameter(s) determining the parabola's opening and orientation.
