Find the solution of Z^5=32 whose argument is strictly between 0 and 90 degrees

tigry1 [53]

Answer:

$\|r\| = 32$ , $\theta = 0\,rad$

Step-by-step explanation:

This complex expression is computed from the De Moivre expression:

$z^{5} = 32\cdot (\cos 5x + i \cdot \sin 5x)$

Given that resultant expression is entirely real, the expression is simplified into this form:

$32 = 32\cdot \cos 5x$

$\cos 5x = 1$

The angle is 0 radians.

I will give brainliest to whoever answers first

2(3x - 4) = 2x + 12

6x - 8 = 2x + 12

4x = 20

x = 5

AB = 3(5) - 4 = 11

AC = 2(5) + 12 = 22

BC = 7(5) - 2 = 35 - 2 = 33

AC:BC = 22:33 = 2:3

Which of the following expressions are equivalent to - ( -5/3)

rewona [7]

There aren’t any following equations, so I’m not sure if this is there. It would be 5/3 if 5/3 is there. This is because two negatives next to each other becomes positive. Hope this helped
