work out the inverse function

y=x-2

Answers

Answer 1

Answer:

x + 2

Step-by-step explanation:

Replace the x with y.

Making is x = y -2

Solve for x=y-2

and you get x+2

Answer 2

Answer:

x+2

Step-by-step explanation:

When doing inverse functions, you switch the x and y.

x = y-2

Then you solve for y (add the 2 to the other side to get "y" by itself)

y = x+2

Answers

Answer: 55%

1. 279 - 180 = 99

2. 99 divided by 180 = 0.55

55 is the percentage

If you were to do the solution to this correctly you would end off with a 55% chance of increasing to ur total.

The coordinates of three vertices of a square are (1, –1), (6, –1), and (6, 4). Fill in each blank to make the statement true. What is the area of the square?

Answers

Answer:

25units²

Step-by-step explanation:

Given the coordinates of three vertices of a square as A(1, –1), B(6, –1), and C(6, 4). The area of the square is expressed as;

A = L² where;

L is the one of the side length of the square.

Note that all the sides of a square are equal;

To get one of the side length, we will find the distance between any two of the coordinates points. Using the coordinates A(1, –1), B(6, –1)

L = AB = √(x2-x1)²+(y2-y1)²

L = √(6-1)²+(-1-(-1))²

L = √5²+0²

L = √25

L = 5

Area of the square = 5²

Area of the square = 25units²

Hence the area of the square is 25units²

Sasha sells T-shirts. Each day she earns a set amount, plus a commission.



Assume Sasha sells 24 T-Shirts in one day. How much would she earn that day?

Answers

Answer:

137$

Step-by-step explanation:

Let the slope of the equation be

[tex]m=\dfrac{\Delta y}{\Delta x}[/tex]

where y = Total pay

x = T-shirts sold

Take any two values of x and corresponding y value

[tex]m=\dfrac{71-68}{2-1}\\\Rightarrow m=3[/tex]

The equation will be

[tex]y=mx+b[/tex]

Finding b

[tex]68=3\times 1+b\\\Rightarrow b=68-3\\\Rightarrow b=65[/tex]

The equation is

[tex]y=3x+65[/tex]

Now sasha sells 24 shirts [tex]x=24[/tex]

[tex]y=3\times 24+65\\\Rightarrow y=137[/tex]

Sasha would earn 137$ on that day.

The ratio of the areas of similar polygons is 64: 16. What is the ratio of their sides

Answers

Answer:

8:4

Step-by-step explanation:

Given that,

The ratio of the areas of similar polygons is 64: 16, A₁:A₂=64: 16

We need to find the ratio of their sides. For similar polygons, the ratio of  the area is proportional to the square of the ratio of their corresponding sides.

Let sides are x₁ and x₂. So,

[tex]\dfrac{A_1}{A_2}=(\dfrac{x_1}{x_2})^2\\\\\dfrac{x_1}{x_2}=\sqrt{\dfrac{A_1}{A_2}} \\\\=\sqrt{\dfrac{64}{16}}\\\\=\dfrac{8}{4}[/tex]

So, the required ratio is 8:4.

La distancia que se recorre por carretera para llegar de Guadalajara a Puerto Vallarta, es de aproximadamente 306 km. Si se viaja a una velocidad promedio de 75km/h ¿cuánto tiempo se hará en ese trayecto?

Answers

Responder:

4.08 horas

Explicación paso a paso:

Velocidad = Distancia / Tiempo

Dado

Distancia = 306km

Velocidad = 75 km / h

Necesario

Hora

De la fórmula;

Tiempo = Distancia / velocidad

Sustituye el parámetro dado y obtén el tiempo;

Tiempo = 306 km / 75 km / h

Tiempo = 4.08 horas

Por lo tanto, utilizará 4.08 horas en ese viaje.

A recent survey by the alumni of a major university indicated that the average salary of 10,000 of its 300,000 graduates was $125,000. What is the Population?

Answers

Answer:

The population is the total number of the universities  graduates  i.e [tex]N = 300,000[/tex]

Step-by-step explanation:

From the question we are told that

  The number of students that are consider is  n = 10,000

   The total number of graduates is  [tex]N = 300,000[/tex]

  The mean is [tex]\= x = \$125 , 000[/tex]

Here the population is The total number of graduates with value  [tex]N = 300,000[/tex], this is because a population is the pool from with a sample is drawn and in this case the pool is [tex]N = 300,000[/tex] while the sample with is drawn is  n = 10,000

The question is, "Find the volume of the bodies given in the figures below, which have a hole along their entire length." How do I measure it the volume in this case?

As you can see, height is 9cm, length is 12, and width is 18 . ​

Answers

Answer:

1782 cm³

Step-by-step explanation:

First, you measure the volume of the cuboid as a whole which is length x breadth x height, 9 x 12 x 18 = 1944 cm³. Then measure the volume occupied by the space, 3 x 3 x 18 since the hole runs along the entire length = 162 cm³.

Then you subtract the volume occupied by the hole from the volume of the cuboid in total, 1944 - 162 = 1782 cm³

Answer:

a. sine StartFraction pi Over 3 EndFraction = StartFraction opposite Over hypotenuse EndFractionEquals StartFraction opposite Over 1 EndFraction  Equals opposite

The length opposite the angle is the vertical distance from the x-axis on the graph.

Step-by-step explanation:

sin (π/3) = opposite/hypotenuse = opposite/1; The length opposite the angle is the vertical distance from the x-axis on the graph.

What is the trigonometric ratio of unit circle?

Unit circle is a circle centered at the origin, (0,0) with radius(r) i.,e r= 1.

The angle π/3 forms an arc of length S and the x-axis and y-axis divide the coordinate plane and the unit circle as it is centered at (0.0).

Also, the terminal side intersect the circle at (x, y). Thus;

sin (π/3) = opposite/hypotenuse = opposite/1

Thus;

sin (π/3) = opposite

Also, the length opposite the angle is the vertical distance from the x-axis on the graph.

Hello!!!

Your answer would in fact Be 24 the steps are super simple what may confuse you is the v it is quite confusing but v is basically a variable that signifies multiplication as it is together with the 4 but this here is an expression because it has nothing equal to it so we have no answer to define what the v is! Also a tip is whenever a number has parenthesis and a number is outside of the parentheses without any sign that signifies multiplication :)!! So as of now if your not learning how to find variable answers then you can basically pretend the v is not needed but have a nice day and I really hope this has helped you!!

The cell cycle is highly regulated and involves many steps to ensure that a cell is ready to divide. For this reason, cells cycle between interphase and mitosis. Suppose a cell culture of 1,000 cells is grown, in which the cells cycle every 24 hours. For a single cell, it takes about two hours from the formation of the dissolution of the nuclear envelope to the separation of two daughter cells.Which of the following best describes the approximate number of cells in the culture that are in interphase, as well as the consequence of the severe disruption of interphase in mitotic division of cells within a tissue?A) There are approximately 917 cells in interphase. Disruption of interphase will have no effect on mitosis because they are two completely independent processes.B) There are approximately 83 cells in interphase. Disruption of interphase will lead to a faster and more efficient mitotic cycle, which will result in increased cell division and tissue growth.C) There are approximately 917 cells in interphase. Disruption of interphase will trigger the cell to switch to a mitotic phase and repeatedly divide, which will result in the massive proliferation of the cells and heightened tissue growth.D) There are approximately 83 cells in interphase. Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide.
