5. magnitude = √10 or appr 3.16 , ok
6. magnitude = √(4+9) = √13 or appr 3.61 , ok
22. ok
23. 5i - 12j , (5+7 used to 12 , not 13 !! )
Could someone check these?
I'm finding the magnitude for 5 and 6.
5. v=3i+j
My magnitude is 3.16
6. v=2i+3j
My magnitude is 3.61
For 22 and 23 I'm finding each specified vector or scalar.
u=2i-5j, v=-3i+7j, w=-i-6j
22. v+w
answer: -4i+j
23. u-v
answer: 5i-13j
