Answer:

Complex numbers

Step-by-step explanation:

Given

[tex](5 + i)[/tex] and [tex](5 - i)[/tex]

Required

Determine what both factors are called

From the list of given options. option "complex numbers" answer the question correctly

This is because when numbers are written in form [tex]a + bi[/tex] where [tex]b \neq 0[/tex] and [tex]i = \sqrt{-1}[/tex];  such a number are referred to as complex number

Some other examples are:

[tex]-7 + 3i[/tex]

[tex]2 - 7i[/tex]

[tex]4 + i[/tex]

And lots more

Answer:

27

Step-by-step explanation:

4^3 is 4*4*4 which is 64

3/4^3 is 3/4*3/4*3/4 which is 27/64

then divide 64 ÷ 27/64

you can cross cancel 64 and get 27.

Answer:

The 10th term of the GP is 2560.

Step-by-step explanation:

It is given that,

The first term of the GP, a = 5

Common ratio, r = 2

We need to find the 10th term of the GP. The nth term of a GP is given by :

[tex]T_n=ar^{n-1}[/tex]

Put n = 10

[tex]T_{10}=5\times 2^{10-1}\\\\T_{10}=2560[/tex]

So, the 10th term of the GP is 2560.

Answer:

1. Dave worked for 34 hours.

2. Perimeter of the rectangle is 172 cm.

Step-by-step explanation:

1. Determination of the hours Dave worked.

Let D represent Dave.

Let M represent Mike.

Let J represent John.

Tota time worked by Dave, Mike and John is 56 hours. This can be written as:

D + M + J = 56 ..... (1)

Dave worked 6 more than 4 times as many hours as Mike. This can written as:

D = 6 + 4M .....(2)

John worked 6 less than 3 times as many hours as Mike. This can be written as:

J = 3M – 6 ........ (3)

Substituting the value of F and J into equation 1, we have:

D + M + J = 56

D = 6 + 4M

J = 3M – 6

6 + 4M + M + 3M – 6 = 56

6 – 6 + 4M + M + 3M = 56

8M = 56

Divide both side by 8

M = 56/8

M = 7

Substitute the value of M into equation (2) to obtain the value of D.

D = 6 + 4M

M = 7

D = 6 + 4(7)

D = 6 + 28

D = 34

Therefore, Dave worked for 34 hours .

2. Determination of the perimeter.

Length (L) = 64 cm

Width (W) = 22 cm

Perimeter (P) =?

P = 2(L + W)

P = 2 (64 + 22)

P = 2 (86)

P = 172 cm

Therefore, the perimeter of the rectangle is 172 cm

Answer:

y + 8 = 2x + 2

Step-by-step explanation:

Use the points given to find the slope.  Divide the difference in y-values by the difference in x-values.

(-1) - (-7) = 6

5 - (-8) = 3

6/3 = 2

The slope is 2.

Now, pick one of the points to put in point-slope form.  It doesn't matter which.  You will get the right answer either way.  I will use (-1, -8).

y - y₁ = m(x - x₁)

y - (-8) = 2(x - (-1))

y + 8 = 2(x + 1)

y + 8 = 2x + 2

Answer:

7

Step-by-step explanation:

9x + 1 = 7x - 9 + 5x - 11

9x + 1 = 12x - 20

9x + 1 - 1 = 12x - 20 - 1

9x = 12x - 21

9x - 12x = 12x - 12x -21

-3x = -21

-3x/3 = -21/-3

x = 7

Answer:

152 (Answer A)

Step-by-step explanation:

The experimental probability of obtaining a head is 19/100, or 0.19.

If the coin is flipped 800 times, the expected number of heads will thus be:

0.19(800 flips) = 152  (Answer A)

(f+g)(x)=f(x)+g(x)=(2x-6)+(4x+7)=6x+1

(f-g)(x)=f(x)-g(x)=(2x-6)-(4x+7)=-2x-13

(fg)(x)=f(x)×g(x)=(2x-6)(4x+7)=8x^2-10x-42

(f+g)(-2)=f(-2)+g(-2)=(2(-2)-6)+(4(-2)+7)=-11

Answer:

Es posible diseñar 936 banderas.

Step-by-step explanation:

Para poder determinar la cantidad de banderas que es posible diseñar utilizando 1 animal, 1 color de fondo y 1 palabra representativa de un total de 8 colores, 13 animales y 9 palabras, se debe multiplicar la cantidad total de variables, y su resultado será la cantidad de banderas que se podrán diseñar.

Así, deben multiplicarse 8 x 13 x 9, es decir, el total de colores, animales y palabras. Esta multiplicación da como resultado 936, con lo cual es posible diseñar 936 banderas diferentes.

Answer:

Step-by-step explanation:

The easiest way to do any of these is to put the fraction into your  calculator and see what comes up.

So for 32/9 you get 3.5555555555 which is the same as 3.5 with a bar over it.

7/30 is the same as .23333333333 which is the same as 0.23 with a bar over the three.

5/3 = 1.6666666 which is 1.6 with a bar over the 6

4/9 is 0.4444444 which is the same as 0.4 with a bar over the 4.

Answer:

Option (A)

Step-by-step explanation:

There are 2 main branches of statistics. They are:

1. Descriptive Statistics

2. Inferential Statistics

Descriptive statistics describes the characteristics of observed subjects or items while Inferential statistics makes inferences, based on given or derived data.

Inferential Statistics allow you to decide whether a difference between the experimental group and control group is due to manipulation or chance.

The Experimental group is the group that an effect is tested on while the Control group is the group that is left untested or uninfluenced. Inferential statistics allow you to decide whether a difference between these 2 groups is due to

- manipulation or interference by any force (which may be the experimenter/researcher)

or

- probability which is chance.

Option a. manipulation; chance

Inferential statistics is a statistical method for estimating the characteristics of a larger population from a small but representative sample. In other words, it enables the researcher to make generalizations about a larger group based on a smaller subset of that group.

Inferential statistics allow you to decide whether a difference between the experimental and the control group is due to a. manipulation; chance
