Question 1196066
Given the vector [-5,12], find the following vectors:
(a) Same direction, twice as long<pre>
Multiply each component by 2</pre>
(b) Same direction, length 1 unit<pre>
Divide each component of original vector by {{{sqrt((-5)^2+(12)^2)}}}</pre>
(c) Opposite direction, length 10<pre>
Multiply each component of the answer to (b) by -10.  The negative is
to make it the opposite direction.</pre>
(d) Opposite direction, length c<pre>
Multiply each component of the answer to (b) by -c.  The negative is
to make it the opposite direction.
