I need help one those 3 questions. Please, help me, and thank you so much!

On numbers 1,2 the choice is parallel, neither or perpendicular.

1.

(1 point) Suppose u = (-1, -1, 0). Then (-1.5, -1.5, 0) is ? V to U (5, -5, -4) is ? to u (1, 4, 3) is ? to u (2, 2, 0) is ? to uPrevious Problem Problem List Next Problem (1 point) Determine whether the given vectors are orthogonal, parallel, or neither. choose one 1. v = (1, 2, -1) and w = (-10, -20, 10). Choose one ~ 2. v = (5, 10, 14) and w - (10, 5, 0) choose one v 3. V = (10, 20, -30) and w = (-30, 20, 10)(1 point) Suppose u = (4, 0, -1). Then (3, -5, 2) makes ? with u (2, 0, 8) makes ? with u (2, 2, -5) makes ? with u (-5, 2, 5) makes ? with u
