Answer:

The correct option is C) 7.

Step-by-step explanation:

Consider the provided equation.

11.3x+7.2=86.3

We need to solve the provided equation for x.

Subtract 7.2 from both side.  

11.3x+7.2-7.2=86.3-7.2

11.3x=79.1

Divide both sides by 11.3.

\frac{11.3x}{11.3}=\frac{79.1}{11.3}

x=7

Hence, the value of the equation is x=7.

Thus the correct option is C) 7.

The interest rate on her account would be 38.4%.

If we use the simple interest formula I=PrT, the principle (P) would be 6000. Assuming that it is based on annual interest, the time (t) would be 1/12. Then, you multiply 6000 by 1/12 to get 500. Finally you divide 192/500 and then multiply by 100.


If the time is based on monthly payments, then do the same thing, except multiply 6000 by 1

What is the future value for a savings account that had $825 deposited in it for 10 years. The
Goshia [24]

Answer:

The answer is 2145$

Step-by-step explanation:

825×0.04=33

Once every quarter of a year means the number of years × 4 = 10×4=40

So

33×40 =1320$

1320+825=2145$

Use DeMoivre's Theorem to find (3cis*pi/6)^3
Sonbull [250]

The correct value of (3cis(pi/6))³ is 27i.

<h3>What is Complex Number?</h3>

Complex numbers are numbers that consist of two parts — a real number and an imaginary number. Complex numbers are the building blocks of more intricate math, such as algebra.

Given the complex number in polar coordinate expressed as

z = r(cos∅+isin∅)

zⁿ =  {r(cos∅+isin∅)}ⁿ

According to DeMoivre’s Theorem;

zⁿ =  rⁿ(cosn∅+isinn∅)

Given the complex number;

(3cis(pi/6))³

= {3(cosπ/6 + isinπ/6)}³

Using  DeMoivre’s Theorem;

= 3³(cos3π/6 + isin3π/6)

=  3³(cosπ/2 + isinπ/2)

= 3³(0 + i(1))

= 27i

Thus, the correct value of (3cis(pi/6))³ is 27i.

Could someone please help me figure out how to set up the equation for this problem? Thanks!
faust18 [17]

Answer:

12

Step-by-step explanation:


The sum of the measures of the interior angles is given by:


(n-2)*180\\


n:sides of the polygon


And in a convex polygon the sum of the exterior angles sums 360°


Then


(n-2)*180=5*(360)


You just solve it and the answer is 12.
