1. Find an ordered pair that represents 6 vector v  5 vector w if vector v =(9,5) and vector w = (6,9).
2. Find an ordered triple that represents 6 vector y + 4 vector z if vector y = (2,6,8) and vector z = (7,2,6)
3. Find the magnitude of vector WX for W(3, –3, 1) and X(8, –3, –6).
4. Vectors A and B have the same direction. Vector A has a magnitude of 8, and Vector B has a magnitude of 5. What must be true about vectors A and B ? (1 point)
They are opposites and parallel.
They are parallel, but not equal.
They are equal, but not parallel.

6v5w = 6(9,5)5(6,9) = (54,30)(30,45) = (24,15)
do #2 the same way
WX = √(5^2+0^2+7^2) = √74
#4: ║ but ≠
#5: ~║ ~opposites ≠
