Given the complex number z=6(cos120+isin120), find z3
Answer:
B
Step-by-step explanation:
We are given the complex number:
[tex]\displaystyle z = 6(\cos 120^\circ + i\sin 120^\circ)[/tex]
And we want to find z³.
Recall that:
[tex]\displaystyle z^n = r^n(\cos(n\theta) + i\sin (n\theta))[/tex]
In this case, n = 3. Hence:
[tex]\displaystyle z ^3 = (6)^3 (\cos (3(120^\circ)) + i\sin (3(120^\circ))[/tex]
Simplify:
[tex]\displaystyle z^3 = 216(\cos 360^\circ + i\sin 360^\circ)[/tex]
Evaluate:
[tex]\displaysyle z^3 = 216( 1 + i(0)) = 216[/tex]
In conclusion, our answer is B.

the sum of twice a number and 13 is 75
•
but in an algebraic equation
DONT SOLVE
Answer:
I won't solve it, because you asked me to.
Step-by-step explanation:
The first question we should ask ourselves is "what are we looking to solve?"
We are looking for some sort of value that satisfies that equation. We'll call it x
Reading from left to right:
The sum of twice a number and 13 is 75
+ 2 x 13 = 75
2x + 13 = 75
In the diagram, what is mAngleVSR?
2 lines intersect. A horizontal line has points R, S, U and intersects a line with points V, S, T at point S. Angle V S U is 100 degrees.
mVSR =
The measure of m∠VSR if the horizontal line has points R, S, U and intersects a line with points V, S, T at point S is 80degrees
The point where two lines intersect is known as an angle.
Find the diagram to the question attached below.
From the diagram shown, we can see that the angle m∠VSR and m∠VSU lie on the line RSU which shows that the sum of these angles is supplementary. Hence:
m∠VSU + ∠VSR = 180
Given that m∠VSU = 100 degrees
∠VSR = 180 - ∠VSU
∠VSR = 180 - 100
∠VSR = 80degrees
Hence the measure of m∠VSR if the horizontal line has points R, S, U and intersects a line with points V, S, T at point S is 80degrees

If there are 95 male students for every 100 female students at Northwest Vista College, to the nearest
0.1%, what percent of the students are female?
Answer:
51.3%
Step-by-step explanation:
You must divide 100 by 195. In order to find the equivalent ratio you must multiply the number you are dividing by, by 100. So it will become 100/195.

A piece of work takes 20 labourers to complete in 10 days. how many labourers will complete the same job in 25 days if they work at the same rate?
Step-by-step explanation:
If 20 labourers=10 days
x labourers = 25 days
10x= 25×20
[tex] \frac{10x}{10} = \frac{25 \times 20}{10}[/tex]
Cancelling out by 10 on both sides
[tex]x = \frac{25 \times 2}{1} \\ x = 50 [/tex]
Therefore, it takes 50 labourers to complete the work at the same rate in 25 days.

The perimeter of a rectangle is 92 cm. If the length is 22 cm, how wide is the rectangle?
A) First write an equation you can use to answer this question. Use w as your variable in the equation.
Answer:
W = 24cm
Step-by-step explanation:
p of a rectangle = 92
L = 22cm and W = ?
p = 2(L+W)
92 = 2(22+W)
92 = 44 + 2W
2W = 92 - 44
2W = 48
W = 48/2
W = 24cm

Rewrite 0.580 80 repeating decimal
Step-by-step explanation:
first off, we'll move the non-repeating part in the decimal to the left-side, by doing a division by a power of 10.
then we'll equate the value to some variable, and move the repeating part over to the left as well.
anyhow, the idea being, we can just use that variable, say "x" for the repeating bit, let's proceed,
\begin{gathered}\bf 0.580\overline{80}\implies \boxed{\cfrac{5.80\overline{80}}{10}}\qquad \textit{now, let's say }x= 5.80\overline{80}\\\\ -------------------------------\end{gathered}

thus

h(t) = 3t2 + 4t
g(t) = t - 1
Find h(g(t))
3t2 - 2t - 1
4+3 - 12t + 1
3t2 + 4t - 1
3t2 - 4t - 1
Answer:
first we need to substitute g(t) value in h(t) value and then evaluate the expression as follows :
h(g(t))=3(t-1)²+4(t-1).
by solving
h(g(t))=3(t²+1-2t)+4t-4
h(g(t))=3t²-2t-1 will.be the final answer
