Answer
a) 3v; b) 2u; c) -3u; d) -2u; e) v
Work Step by Step
a) $\overrightarrow{OA}$ has the same direction as $v$ and the magnitude 3 times as $v$, therefore
$\overrightarrow{OA}=3v$.
b) $\overrightarrow{OD}$ has the same direction as $u$ and the magnitude 2 times as $u$, therefore
$\overrightarrow{OD}=2u$.
c) $\overrightarrow{OH}$ has the same direction as $-u$ and the magnitude 3 times as $u$, therefore
$\overrightarrow{OH}=-3u$.
d) $\overrightarrow{AG}$ has the same direction as $-u$ and the magnitude 2 times as $u$, therefore
$\overrightarrow{AG}=-2u$.
e) $\overrightarrow{CE}$ has the same direction as $v$ and the magnitude as $v$, therefore
$\overrightarrow{CE}=v$.
