Answer 1

could you solve the system and get the values of x and y?

Answer 2

ok i'll brb with x, y

Answer 3

the x,y is 6, 3

Answer 4

so, the magnitude of v = 6i + 3j
would be ??

\(||v| = \sqrt{x^2+y^2} = .. \\ \arctan(\dfrac{y}{x}) = ..?\)

Answer 5

Ok, the magnitude is 7 (6.708)
But the angle looks like it's supposed to be 30 just going off of co ordinates but I don't think it is.

Answer 6

yes, the options does not seem to be correct..
angle i got is 26.57 degrees.

Answer 7

I'll have to ask my teacher about this. But I still learned something, so thank you!

Answer 8

welcome ^_^
