What is 39/3 as a mixed number?
likoan [24]
Converting to a mixed number is the same as dividing and leaving the remainder.
Say we had 5/2...we would divide 5 by 2 and end up with 2 r1, right?
So 5/2 = 2 1/2

As for 39/3...we divide 39 by 3...and get exactly 13! There's no remainder, so you don't even need any additional fractions.

2. David determines that 3 sqrt 2 cis(7pi/4) = -3+3i. When he considers the graphical representation of these numbers, he knows
fiasKO [112]

The correct rectangular equivalence of 3sqrt(2)·cis(7pi/4 ) is:

3sqrt(2)·cos( 7pi/4 ) + i·sqrt(2)·sin( 7pi/4 )  =  3 - 3i.

<h3>Where did David go wrong?</h3>

David mistakenly interchanged the Sin function and the Cos function when he was calculating the problem.

Hence the correct rectangular equivalence is:

3sqrt(2)·cos( 7pi/4 ) + i·sqrt(2)·sin( 7pi/4 )  =  3 - 3i.

<h3>What is rectangular equivalence?</h3>

An equation is rectangular in form when it is comprised of Variables like X and Y and can be represented on a Cartesian Plane.
