-5i can be written as 0 + (-5)i
It is in the form a+bi where a = 0 and b =-5
So the point (a,b) is (0,-5)
The distance from the origin to this point is 5 units, therefore r = 5. This is the magnitude.
The angle is 270 degrees as shown in the attached image. You start on the positive x axis and rotate until you reach the point (0,-5)
This is why the
answer is choice A) 5(cos(270) + i*sin(270))
In order to do this we need to make them both fractions, or both decimals. It's much easier to make them both decimals, as you can get
into decimal form by simply dividing 1 by 5.
If 1/5 = .20, then 1/5 is greater than .15!
B and D if you multiply 13 by z it would be 13z and you can add 5 and 8 because they have the same variable equaling 13z
