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]

The correct answer is an option (b)

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

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

-17z - 12 + 15z = -12 - 2z

-2z - 12 = -2z - 12

-12 = -12

Since this statement is always true for all real values of z, there are infinitely many solutions.

Step-by-step explanation:

L = 2.5

W x 25/16 = 2.5

w = 2.5 x 16 / 25 = 1.6

LWH = V

H = V / LW = (12 3/4) / (2.5 x 1.6) = 3.19

Answer:

x+2y=13

Step 1: Add -2y to both sides.

x+2y+−2y=13+−2y

x=−2y+13

Step 1: Add 5y to both sides.

3x−5y+5y=6+5y

3x=5y+6

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:

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
