Rectangular form of z is z = 3 +  2i

Polar form of complex number is (r , \theta).

In general if z = x + iy

r =  \sqrt{x^2 + y^2}

\theta = tan^{-1} \frac{y}{x}

So in given complex number z = 3 + 2i

So r is
 r =  \sqrt{(3)^2 + (2)^2}
           =  \sqrt{9 + 4 } =  \sqrt{13}

\theta = tan^{-1} ( \frac{y}{x}) = tan^{-1} ( \frac{2}{3}}
                  = 33.703 degree.

So the rectangular form is ( \sqrt{13} , 33.703 degree ).

My answers have two options with sqr root of 13. Of the two which could it be?

z=sqr rt of 13(cos56 + i sin56)

z=sqr rt of 13(cos34 + i sin34)

Answer:

HI ≈ 12.22

Step-by-step explanation:

tan I = GH / HI

tan 42° = 11 / HI = 0.90

HI = 11/0.90 = 12.22

Plz explain how to do this!!!
cestrela7 [59]

Answer:

Step-by-step explanation:

You are trying to find the value of K, so to do that you need to get k by itself (example : K= 3-5 instead of K+5= 3)

So in 1a i would simplify 7k-3k= 4k

then 4k=11

now to get rid of the 4 and get the k alone- you DIVIDE 4k by 4 and divide 11 by 4 cause you need to do it on both sides of the equation, it should look like this.

4k= 11

-   =  -

4      4

(4k over 4 and 11 over four)

so the answer is k = 2.75  cause 11/4 = 2.75
