Solve for the roots in the equation below. In your final answer, include each of the necessary steps and calculations.

Nostrana [21]

$x^3-27i=0$
$x^3=27i$
$x^3=27e^{i\pi/2}$
$x=\left(27e^{i\pi/2}\right)^{1/3}$
$x=3e^{i(\pi/2+2\pi k)/3}$
$x=3e^{i\pi(4k+1)/6}$

where $k\in\{0,1,2\}$ . This means you have

$x=3e^{i\pi/6}=\dfrac32(\sqrt3+i)$
$x=3e^{i5\pi/6}=\dfrac32(-\sqrt3+i)$
$x=3e^{i9\pi/6}=-3i$

as the solutions to the original equation.

Igoryamba

Answer: 41/75 or 54.67%

Step-by-step explanation:

Buttons --- yes, zips --- yes = 45 (compute as 150 - 37 - 45 - 23)

Buttons --- yes, zips --- no = 37

Buttons --- no, zips --- yes = 45

Buttons --- no, zips --- no = 23

Therefore, 82 out of 150 bags have buttons so probability = 82/150 = 41/75

The acceptable length of the rod that has the standard length of 30.5 cm and can only from the ideal length by at most 0.015 cm is from 30.485 cm to 30.515 cm. This is computed by deducting and adding 0.015 cm to the standard length.
