Best ResponseYou've already chosen the best response.1I'm not understanding the vector parts. Sorry about this, but unfortunately, I'm not an expert at these sorts of questions. Maybe you should ask someone else. @whpalmer4 are you good at these questions at all?

Best ResponseYou've already chosen the best response.0\[r(t) = (1t)<1,3,2> + t<2, 1, 3>\]You essentially treat it like distributing and collecting terms: \[r(t) = <1(1t),3(1t),2(1t)> + <2t,t,3t> = <1t+2t, 33tt,2+2t+3t> =\]\[= <1+t,34t,2+5t>\]
