The equivalent complex expression of [tex](\frac{1}{2}(cos(\frac{\pi}{5} )+i~sin(\frac{\pi}{5} )) )^5[/tex] is

[tex]\frac{1}{32} (cos(\pi)+i~sin(\pi))[/tex]

The correct answer is an option (b)

"The number of the form a + ib, where a, b are real numbers and [tex]i=\sqrt{-1}[/tex]"

"This theorem gives a formula for computing powers of complex numbers.

[tex](r(cos\theta+i~sin\theta))^n=r^n~(cos(n\theta)+i~sin(n\theta))[/tex] "

For given question,

We have been given a complex expression [tex](\frac{1}{2}(cos(\frac{\pi}{5} )+i~sin(\frac{\pi}{5} )) )^5[/tex]

Using the DeMoivre's theorem,

[tex](\frac{1}{2}(cos(\frac{\pi}{5} )+i~sin(\frac{\pi}{5} )) )^5\\\\=(\frac{1}{2})^5~((cos(\frac{\pi}{5} )+i~sin(\frac{\pi}{5} )) )^5\\\\=\frac{1}{32} (cos(\frac{5\pi}{5} )+i~sin(\frac{5\pi}{5} )) )\\\\= \frac{1}{32} (cos(\pi)+i~sin(\pi))[/tex]

Therefore, the equivalent complex expression of [tex](\frac{1}{2}(cos(\frac{\pi}{5} )+i~sin(\frac{\pi}{5} )) )^5[/tex] is

[tex]\frac{1}{32} (cos(\pi)+i~sin(\pi))[/tex]

Step-by-step explanation:

6.14-(9+8)2

6.14-17(2)

6.14-34=

-27.86

Hope this helped!

The required simplified value of the 6.14-(9+8)2 is -27.86.

Given that,
An expression  is given, 6.14-(9+8)2
A simplified value is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
= 6.14-(9+8)2
Using the PEMDAS rule,
Using distributive property in order to solve the parenthesis first.
= 6.14 - 17 * 2
Following PEMDAS solve 17 * 2 first.
= 6.14 - 34
Now, subtraction
= -27.86

Thus, the required simplified value of the 6.14-(9+8)2 is -27.86.

Step-by-step explanation:

Answer:

65º

Step-by-step explanation:

(the sum of the angles of a triangle) 180- 65= 115

65= 30+ 35

180- 115=65

Answer:

I'm pretty sure the answer is 65

Step-by-step explanation:

30+35=65

180-65=115

So the 3rd angle in the triangle is 115°

Then you subtract 115 from 180 and get 65°

So S equals 65°

Answer:

14

Step-by-step explanation:

Answer:

one: 9

Two: D

Step-by-step explanation:

One

The symbol used is x≥8 so 8 is included in the function part. That would mean that F(x) = 9

Two

The value you need to use is -4x + 3. That's because -2≤x and the symbol ≤ makes - 2 inclusive.

-4(-2) + 3 = 8 + 3 = 11

3a

The function is decreasing over -4x + 3

It goes from 11 to -29 roughly. That means it's going from a positive to negative number. Definitely decreasing

3b

The function is a constant when x≥8. The value of the function is 9 no matter what x is.

3c

The function is increasing from - 2x to 8 which is going from -9 to 11

Answer:

  x = 6

Step-by-step explanation:

The angle bisector divides the triangle proportionally. Here, the top segment on each half is double the length of the bottom one, (8 = 2·4), so ...

  x = 2·3

  x = 6

_____

If you like, you can write that as a proportion:

  x/3 = 8/4

  x = 3(8/4) = 3·2 . . . . . multiply by 3 to get x by itself

  x = 6

Answer:

x+2y=13

Step 1: Add -2y to both sides.

x+2y+−2y=13+−2y

x=−2y+13

Answer:

x=−2y+13

Step 1: Add 5y to both sides.

3x−5y+5y=6+5y

3x=5y+6

Step 2: Divide both sides by 3.

Answer:

7

Step-by-step explanation:

This is a Poisson distribution problem with the formula;

P(x;μ) = (e^(-μ)) × (μ^(x))/x!

We are told that the grocer sells three of a certain article per week. Thus;

μ = 3

Now, we want to find out How many of these should he have in stock so that the chance of his running out within a week is less than 0.01.

This means;

P(X > k) < 0.01

This can be rewritten as;

P(X ≤ k) < 0.99

Let's try x = 8

P(8;3) = (e^(-3)) × (3^(8))/8!

P(8;3) = 0.008

But; P(X ≤ 8) = 1 - 0.008 = 0.992

This is more than 0.99 and thus is not the answer

Let's try x = 7

P(7;3) = (e^(-3)) × (3^(7))/7!

P(7;3) = 0.022

But; P(X ≤ 7) = 1 - 0.022 = 0.978

Thus is less than 0.99.

Thus, stock should be 7

Answer:

Plane RTS

Step-by-step explanation:

Answer: Choice D) Plane PQY

==========================================================

Explanation:

By definition, a plane is formed by 3 non-collinear points. The three points cannot all be on the same line. If you had 3 points on the same line, then infinitely many planes are possible. Imagine the plane spins around the line as a sort of fan blade.

Choice A can be ruled out because points R, T, and S are all on the same line. They are collinear points. Using these three points is not enough to properly identity/label this plane, since infinitely many other planes could result.

Choices B and C can also be ruled out for similar reasons.

Choice D is correct because points P, Q, and Y are all in plane M, and also because they are not all on the same line.

Side note: another way to phrase "a plane is formed by 3 non-collinear points" is to say "a plane is formed by 3 points that form a triangle".

Answer:

The simplified value is 1/12.

Step-by-step explanation:

Since we need to multiply these fractions, we can just multiply the numerators and denominators together in order to find the answer.

2/3 x 1/8 =

2/24 =

1/12

Therefore, the simplified value is 1/12.
