Can you answer these vector questions

[From: ] [author: ] [Date: 13-01-21] [Hit: ]
a) (4,5) and (3,b) (6,7) and (9,c) (3,7) and (-2,......
1. Can you put these vectors into pairs that are parallel?
a) r+s b) t-v c) 3t-3v d) 5r+5s e) 3r+2s f) 2t-3v g) 4s+6r h) 6v-4t

2. Calculate the length of the vector given between the given co-ordinates (answers to 1 d.p.)
a) (4,5) and (3,6)
b) (6,7) and (9,5)
c) (3,7) and (-2,5)
d) (-2,-6) and (0,-2)

Please help I really need this!

1.The paired vectors are exactly the same letters and signs, just with a greater magnitude. e.g. r + s is parallel to 5r + 5s because 5r + 5s = 5*(r+s)

a and d, b and c, e and g, f and h

2. The length of a vector, given two points is like this:
(x1,y1) and (x2,y2)

length = sqrt((x2-x1)2 + (y2-y1)2)

to explain another way, the square root of the( (square of the difference between the x values) + (the square of the difference between the y values))
a) 1.4
b) 3.6
c) 5.4
d)4.5
