Solve <br> 2z = modulus of z + 2i

Marta_Voda [28]

I assume the equation is

$2z=|z|+2i$

then let $z=x+iy$ .

$2x+2iy=\sqrt{x^2+y^2}+2i$

$2x+2i(y-1)=\sqrt{x^2+y^2}$

The right side is real-valued and positive, and only on the left side do we have an imaginary term, which tells us

$2(y-1)=0\implies y=1$

Then

$2x=\sqrt{x^2+1}$

$4x^2=x^2+1$

$3x^2=1$

$x=\pm\dfrac1{\sqrt3}$

but again we omit the negative solution, so that

$\boxed{z=\dfrac1{\sqrt3}+i}$

5 1/3 + (-4 1/6)+ (-2 1/2)

nlexa [21]

Answer:

$-\frac{4}{3}$

Step-by-step explanation:

We are given that

$5\frac{1}{3}+(-4\frac{1}{6})+(-2\frac{1}{2})$

We have to find the value of given expression

$\frac{5(3)+1}{3}-(\frac{4(6)+1}{6})-(\frac{2(2)+1}{2})$

$=\frac{15+1}{3}-\frac{24+1}{6}-\frac{4+1}{2}$

$=\frac{16}{3}-\frac{25}{6}-\frac{5}{2}$

LCM(2,3,6)=6

$=\frac{32-25-15}{6}$

$=\frac{32-40}{6}$

$=\frac{-8}{6}$

$=-\frac{4}{3}$
