Best ResponseYou've already chosen the best response.0\[2i+4j+2k=\sqrt{(2)^2+4^2+2^2}=2\sqrt{6}\] \[\vec{a}=\alpha(2i+4j+2k)\quad,\quad\alpha=\frac{6}{2\sqrt{6}}=\frac{\sqrt{6}}{2}\] \[vec{a}=\frac{\sqrt{6}}{2}(2i+4j+2k)=\sqrt{6}i+2\sqrt{6}j+\sqrt{6}k\]

Best ResponseYou've already chosen the best response.0(1,0,0) lies in x, (0,0,1) lies in z, so (0,1,0) will lie in y which is perpendicular to xz.

Best ResponseYou've already chosen the best response.0Yes, go into equation editor below, and there's a set of boxes to the right you can use. You can also type, sqrt{x} directly into the equation line to get\[\sqrt{x}\]
