By DeMoivre's theorem, you have

and converting back to Cartesian form, this number is equivalent to
Answer:
yes both are the distance of 99mm
Answer:
Solution given:
we have
y=5x-1
equating equation with y=mx+c
we get
slope [m]=5
we have
for parallel
slope are equal
So
<u>the</u><u> </u><u>required</u><u> </u><u>slope</u><u> </u><u>is</u><u> </u><u>5</u><u>.</u>
