Vector u has its initial point at (-7, 2) and its terminal point at (11, -5). vector v has a direction opposite that of vector u, and its magnitude is three times the magnitude of u. what is the component form of vector v?
Answers: 1
![\bf u\implies \begin{cases} (-7,2)\\ (11,5) \end{cases}\implies [11-(-7)]~,~[5-2]\implies (11+7)~,~(5-2) \\\\\\ \stackrel{\textit{component form}}{\ \textless \ 18~,~3\ \textgreater \ }\\\\ -------------------------------\\\\ ||u||=\sqrt{18^2+3^2}\implies ||u||=\sqrt{333}\implies ||u||=\sqrt{9\cdot 37} \\\\\\ ||u||=\sqrt{3^2\cdot 37}\implies ||u||=3\sqrt{37}\\\\ -------------------------------](/tpl/images/0057/0659/c92ac.png)
