Answer:
option B

Step-by-step explanation:
Given in the question a complex fraction
<h3>Step1</h3>
To divide complex numbers, you must multiply by the conjugate. To find the conjugate of a complex number all you have to do is change the sign between the two terms in the denominator.

<h3>Step2</h3>
Distribute (or FOIL) in both the numerator and denominator to remove the parenthesis.

<h3>Step3</h3>
Simplify the powers of i, specifically remember that i² = –1.

<h3>Step4</h3>

<h3>Step5</h3>
simply

Answer:
-0.89 (i think)
Step-by-step explanation:
Since the graph seems to be going downwards from the right, it has a negative correlation. And since the data seems to be pretty close together, the correlation must be strong. That narrows the answer down to -0.89
If its wrong then i'm not a smart person, and it's -0.15
9(2x-1)=3(x+2)+3x
18x-9=3x+6+3x
18x-9=6x+6
18x-6x=6+9
12x=15
x=15/12
x=5/4
Answer:
n= 13.8 years
Step-by-step explanation:
<u>First, we need to determine the daily interest rate:</u>
Daily interest rate= 0.03 / 365
Daily interest rate= 0.000082
<u>Now, using the following formula we can determine the number of days and years:</u>
n= ln(FV/PV) / ln(1+i)
n= ln(13,000 / 8,600) / ln(1.000082)
n= 5,039 days
<u>In years:</u>
n= 5,039/365
n= 13.8 years
if you add them all its 340 and the square number is 9
