What Ln(z) is answer????!!

dimaraw [331]

Write <em>z</em> in exponential form:

$z=1-i=\sqrt2 e^{-i\frac\pi4}$

Then taking the logarithm, we get

$\mathrm{Ln}(z)=\ln(\sqrt2) + \ln e^{-i\frac\pi4} = \boxed{\ln(\sqrt2)-\dfrac\pi4i}$

so a is the correct answer.

what is a rational number that is between 5.2 and 5.5. what is a irrational number that is between 5.2 and 5.5.

Katyanochek1 [597]

5.2 < x < 5.5
square
5.2² < x² < 5.5²
27.04 < x² < 30.25
Pick any number for between 27.04 and 30.25 for x², as long as it's not a perfect square. So you could pick 30.

x² = 30

x = √30 → irrational number between 5.2 and 5.5

5. What is the solution to the equation -2.5(x-4)=-3x+4?

lana66690 [7]

Answer:

x = -12

Step-by-step explanation:

-2.5(x-4)=-3x+4

Distribute

-2.5x +10 = -3x +4

Add 3x to each side

-2.5x+10 +3x = -3x+4+3x

.5x +10 = 4

Subtract 10 from each side

.5x+10-10=4-10

.5x = -6

Divide by .5

.5x/.5 = -6/.5

x = -12
