13. [P] Particle 1 starts at point (3, 1, 1) and particle 2 starts at point (10,5,-4); at t = 0, both particles begin to move along linear paths. After 1 second, particle 1 is at point (4, 3, 4) and particle 2 is at (8, 6, 3). (a) Do the paths of the particles intersect? (b) Will the particles collide?

2.3(2)   Determines, if possible, the point(s) of intersection of each line and each plan defined by the equations.

7. The function of f(y) is a "sideways" parabola with a standard equation of f(y) =ay²+by+c. f(y) has the focus located at (2,6) and a directrix at x = -15. Determine the equation of the "sideways" parabola in standard form. ©-000 f(y) =!
