The sum of two vectors is (- 0.5, 10.1)
<u>Explanation:
</u>
To add two vectors, add the corresponding components.
Let u =⟨u1,u2⟩ and v =⟨v1,v2⟩ be two vectors.
Then, the sum of u and v is the vector
u +v =⟨u1+v1, u2+v2⟩
(b)
Two vectors = ( 3, 4 )
angle 2π/3 = 120°
In x axis, the vector is = 7 cos 120°

In y axis, the vector is = 7 sin 120°
= 7 X 0.866
= 6.062
The second vectors are ( -3.5, 6.062)
Sum of two vectors = [( 3 + (-3.5) ), (4 + 6.062)]
= (- 0.5, 10.1)
First plug in the numbers 5 x 8 = 40
40-4y+6x8=48
40-4y+48
24 + 11 = 35 + 11 = 46 + 11 = 57 + 11 = 68 +11 = 79 + 11 = 90 + 11 = 101
17 + 12 = 29 + 12 = 41 + 12 = 53 + 12 = 65 + 12 = 77 + 12 = 89 + 12 = 101
