ANSWER

$5{e}^{i \frac{5\pi}{3} }$

EXPLANATION

The exponential form of complex numbers is given by;

$z =r {e}^{i \theta}$

The given complex number in polar form is:

$5( \cos( \frac{5\pi}{3} + i \sin( \frac{5\pi}{3}) )$

We have r=5 from the question and

$\theta = \frac{5\pi}{3}$

We substitute these values to obtain the exponential form:

$z =5{e}^{i \frac{5\pi}{3} }$

The correct answer is C

Use the digits 1-7 to create a seven-digit number that can be rounded to 6,300,000.

Alla [95]

There are many ways to figure this out. One way is 6,275,431.
You just need to start the number with a 6, followed by a 2 and 5 or 7, then you can mix up the rest of the numbers any way you want.

Mary spent 3/4 of her money on a jacket. She spent 1/4 of the remainder on a shirt. The jacket cost $33 more than the shirt. How

Leviafan [203]

$49.50 the jacket costs this because her total amount was $66. to find total money I said 3/4x - 1/4x = $33 so 1/2x =$33 and x= $66. then multiply the total by 3/4 to get $49.50
