what is the length(magnitude) of the vector (6,-3)? a.3 sqrt 5 b.sqrt 2 c.3 d.sqrt 53

TheSmartOne (thesmartone):

Magnitude of the vector <a, b> is \(\sqrt{a^2 + b^2}\)

OpenStudy (sneha):

oh so would it be 6.7

OpenStudy (sneha):

Is that right?

TheSmartOne (thesmartone):

don't plug in whatever you under the sqrt in a calc, you need to simplify it to get your final answer :)
