Trig: Which complex number's graph is shown?

Andrei [34K]

ANSWER

$2 \sqrt{2} ( \cos( \frac{7\pi}{4} + i \sin( \frac{7\pi}{4} ) )$

EXPLANATION

The complex number shown has coordinates (2,-2)

$z = 2 - 2i$

The modulus is

$|z| = \sqrt{ {2}^{2} + {( - 2)}^{2} }$

$|z| = \sqrt{ 8} = 2 \sqrt{2}$

The argument is

$\theta= \tan^{ - 1} ( \frac{ - 2}{2} )$

$\theta= \tan^{ - 1} ( -1) = \frac{7\pi}{4}$

The polar form is

$2 \sqrt{2} ( \cos( \frac{7\pi}{4} + i \sin( \frac{7\pi}{4} ) )$

The first option is correct.

Use the Venn diagram about students’ pets to solve. How many students do not have a cat or a dog?

Gennadij [26K]

There is no Venn diagram so how do we solve it. There is nothing to help us with this answer so right now there is no definite amount.

Savanna Smiles invested $5,000 for one year in a CD that earns interest at a rate of 3.5% compounded monthly. What is the intere

weeeeeb [17]

We are asked to solve for the interest during the year given that it is compounded monthly, we are given with the formula A = P(1+r)^n. The solution is shown below:
A = P (1+r)^n
A = $5,000 (1+ 3.5/12)^(12*1)
A = $5,000 (1.000292)^12
A = $5,177.84
