Answer:
√1394
Step-by-step explanation:
The resultant vector is the specified sum of the component vectors.
v - 5u = <-7-5(-4), 5-5·8> = <13, -35>
The magnitude of the result is the root of the sum of the squares of the components.
║v -5u║ = √(13² +(-35)²) = √1394
Answer:
29
Step-by-step explanation:
If all the multiples are removed, you'll be left with prime numbers only
2, 3, 5, 7, 11, 13, 17, 19, 23, 29..
The tenth prime no. is 29
To figure this out i would just dived 2.8 by 3 then multiply by two. I do not know if you must keep it as a fraction but this is the easiest way for me to do it
