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.

Jake leaned a 12-foot ladder against his house. If the Angle formed by the ladder and the ground is 68, how far from the base of
zhuklara [117]

Answer:

4.50\ ft

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle ABC

cos(A)=\frac{AC}{AB} -----> the cosine is the adjacent side to angle A divided by the hypotenuse

substitute the values and solve for x

cos(68\°)=\frac{x}{12}

x=12*cos(68\°)=4.50\ ft

SashulF [63]

Answer:

Step-by-step explanation:

It's 30 days by 9p. Take that total and convert it.

Hopefully this helps you.
