Find the sum of each pair of vectors and match it with the magnitude of the resultant vector.
magnitude 3.5 m/s, direction angle 35
magnitude 4 m/s, direction angle 150
magnitude 4.5 m/s, direction angle 55
magnitude 3 m/s, direction angle 135
magnitude 3 m/s, direction angle 70
magnitude 5 m/s, direction angle 210°
magnitude 6 m/s, direction angle 120
magnitude 2 m/s, direction angle 240
5.83 m/s
4.05 m/s
5.29 m/s
3.32 m/s

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
