Question

find the magnitude of wx for w(-3,5,4) and x(9,5,3)
i think its sqrt145

Answer 1

That looks right, but I'm not for sure. Sorry

Answer 2

thanks anyways

Answer 3

multiply

Answer 4

wx = (9-(-3), 5-5, 3-4)
wx = (12, 0, -1)

|wx| = sqrt(12^2 + 0^2 + (-1)^2)
|wx| = sqrt(145)


so you have the right answer

Answer 5

thanks
