Answer:

A'(5,3)

Step-by-step explanation:

First, you must understand that A(5,3) is the pre-image and that A' is what we are looking for which is the image.

With that in mind, you translate the preimage by adding or subtracting from the x and y values.

(x+4, y-3)

To find the x value of the pre-image, you will add 4 to the preimages' x value

Pre-image: A(1,6)

To find the y value, you subtract the preimages' y value by 3.

Hope this helps!

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.
