Write -6 - 8i in polar form<br> Appreciate any help thank you so much!

Temka [501]

-6 = r cos α and -8 = r sin α

r = sqrt( 6^2 + 8^2) = sqrt 100 = 10

α = arctan ( -8/-6) = arctan (4/3) = 53.13 degrees

polar firm = r ( cos α + i sin α)
= 10(cos 53.18 + i sin 53.18)

its been a long time but ui think thats correct

Answer:

5x -3y = 44

Step-by-step explanation:

We choose to start with the form ...

(Δy)x -(Δx)y = (Δy)(x1) -(Δx)(y1) . . . . . where Δy = y2 -y1 and Δx = x2 -x1

For this purpose, it is convenient to choose y2 > y1, so we have ...

Δy = -3 -(-8) = 5

Δx = 7 -4 = 3

5x -3y = 5(4) -3(-8)

5x -3y = 44
