Answer:

-16 sqrt(3) +16i

Step-by-step explanation:

z = 2 cis (pi/6)

z^5 = 2^5 cis (5*pi/6)

z^5 = 32 cis (5pi/6)

 z^5 = 32 cos (5pi/6) + 32 i sin (5pi/6)

        = 32 * (-sqrt(3)/2) + 32i (1/2)

        = -16 sqrt(3) +16i

What's the radius of a circle with an area of 64 square feet?
Nady [450]
Area = \pi r ^{2}
64 = \pi r ^{2}
\frac{64}{ \pi } =r^2
r= \frac{ \sqrt{64} }{ \sqrt{ \pi } } = \frac{8}{ \sqrt{ \pi } }

If you want the denominator rationalized, the answer is \frac{8 \sqrt{ \pi } }{ \pi }

How does 8 4/3 = 9 1/3?​
irga5000 [103]

You're question asks why the given mixed numbers are equal.

In fact, they're equal.

Lets make it easier for you to understand:

8 4/3 has a improper fraction "4/3", that fraction is over 1 whole.

You could look at 8 4/3 as:

8 + 3/3 + 1/3

The 3/3 turns into 1:

8 + 1 + 1/3

9 + 1/3

9 1/3

You would see that it turns into 9 1/3, therefore they are equal.
