Domain: [tex]\{x|x\in\mathbb{R}\}[/tex]
Range: [tex]\{y|y\in\mathbb{R},y\leq -2\}[/tex]
Step-by-step explanation:
The domain is the span of x-values the graph covers.
The range is the span of y-values the graph covers.
The given graph is a quadratic. We can see that the x-values will extend infinitely in both directions.
Thus, the domain is all real numbers.
In set notation, this is:
[tex]\{x|x\in\mathbb{R}\}[/tex]
From the graph, we can see that the maximum value is y=-2. The graph won't ever go above this.
So, the range is all real numbers less than or equal to -2.
In interval notation, this is:
[tex]\{y|y\in\mathbb{R},y\leq -2\}[/tex]
And we are done :)

Step-by-step explanation:
The domain of a relation is all of the x-coordinates.
So we have the relation:
{(-5,4), (-4,2), (0,2), (1,3), (2,4)}
This means that the domain will be the following values:

Find the number of ways of arranging the letters of the word MOSHOESHOE, if the letter M must always begin a word
Answers
Answer:
7560.
Step-by-step explanation:
There are 9 letters after the M consisting of 3 O's, 2 H's, 2 H's and 2 E's.
So the number of ways is 9! / (3!*2!*2!*2!)
= 362880 / (6*2*2*2)
= 362880 / 48
= 7560.
The number of ways the word MOSHOESHOE can be rearranged, if the letter M must always begin a word is 75,600 ways
Given:
MOSHOESHOE
n = total number of letters = 10
a = number of times O appears = 3
b = number of times S appears = 2
c = number of times E appears = 2
d = number of times H appears = 2
number of ways the word can be rearranged if M must always begin a word
= n! / (a! b! c! d!)
= 10! / (3!, 2!, 2!, 2!)
= (10 × 9 × 8 × 7 × 6 × 5 × 4× 3 × 2 × 1) / (3 × 2 × 1, 2 × 1, 2 × 1, 2 × 1)
= 3,628,800 / (6 × 2 × 2 × 2)
= 3,628,800 / 48
= 75,600 ways
Therefore, the number of ways the word can be rearranged if M must always begin a word is 75,600 ways

a. Write an equation for y in terms of x.
Answers

Step-by-step explanation:
If x represents the number of pages typed, 5x will represent how much money he earns from typing them, since he gets $5 per page.

What subset of real numbers does 18.5 inches belong to?
Answers
Answer:
The correct answer is rational.
Step-by-step explanation:
The diameter of the tree belongs to the subset of rational numbers.
Natural numbers are the numbers 1, 2, 3 4, etc. Since 18.5 has a fractional/decimal component, it is not considered a natural number. Whole numbers include all of the natural numbers, as well as 0; therefore, 18.5 is not a whole number either.
Integers include all whole numbers as well as negative numbers, but the integer category still does not encompass numbers with a decimal component. For this reason, 18.5 is not an integer either.
Therefore, the only subset of numbers that 18.5 can fall under is rational numbers. A rational number is a number that can be represented as a fraction. 18.5 can be represented as 37/2 and is thus a rational number.
You can also refer to the infographic given in the question for further clarity on which subsets of numbers are more inclusive than others.

Explain the difference between f(2) and f(x) = 2. Use a verbal explanation and create examples to make it very clear. Please help me out
Answers
Let x be a variable, and f(x) a function of that variable.
f(2) is a number ; it's the value of the function f(x) when x = 2, assuming that value exists.
f(x) = 2 is a statement ; it says there is some value of x for which the function returns a value of 2. Because it's a statement, it can be true or false.
Here's an example:
Define f(x) = sin(x). Then f(2) = sin(2) ≈ 0.909297.
If x is a real number, then the statement sin(x) = 2 is false, because -1 ≤ sin(x) ≤ 1 for all real x.
If we replace 2 with 1, on the other hand, we get
f(1) = sin(1) ≈ 0.84147
and
sin(x) = 1 ==> x = π/2 + 2nπ
where n is any integer. (So we're talking about numbers like π/2, -3π/2, 5π/2, -7π/2, and so on.) We're saying here that any real number x of the above form satisfies the equation and makes the statement true.

El operador de un elevador registro el numero de pisos que este subio y bajo en varias ocaciones para llegar a la planta baja hasta el piso 9 si en total se hicieron 5 movimientos 2 de bajada y 3 de subida que operacion podria indicar la cantidad de pisos que el elevador subio bajo en cada movimiento
Answers
Answer:
Supongo que en realidad dice
"... Para llegar de la planta baja hasta el piso 9..."
Ok, el elevador comienza en el piso 0, y llega hasta el piso 9 después de 5 movimientos.
De estos 5 movimientos, 3 suben (los podemos definir como positivos)
y 2 bajan (los escribimos como negativos).
Entonces, comienzo en 0.
0 + A + B + C - D - E = 9.
ahí dice que:
"desde el piso 0, tengo 3 subidas y dos bajadas de tal forma que el resultado final es el piso 9"
Una expresión algebraica matemática consta de variables y constantes junto con operaciones algebraicas. Al resolver problemas de palabras algebraicas, es necesario que los problemas se traduzcan con precisión en ecuaciones y se resuelvan correctamente.
Dado que:
Un operador quiere llegar al noveno piso superior desde la planta bajaEl número total de sus movimientos = 5 movimientosNúmero de movimientos hacia arriba = 3Número de movimientos hacia abajo = 2Para configurar una operación que indique el número de pisos que recorrió el ascensor con cada movimiento;
Vamos a considerar
el número de movimientos hacia arriba (es decir, elevado) será = (a)el número de movimientos hacia abajo (es decir, hacia abajo) para ser = (b)∴
Número de movimientos hacia arriba = 3 × a = 3aNúmero de movimientos hacia abajo = 2 × b = 2bAsí, la puesta a punto de la operación que indica el número de pisos que recorrió el ascensor con cada movimiento se puede deducir de la diferencia entre el movimiento de subida y bajada será igual a 9.
Por lo tanto, podemos concluir que la configuración de la operación es:

A map has a scale of 1:100,000 what is the map distance between two cities if the real distance was 20km
Answers
Step-by-step explanation:
I guess you mean 1cm:100000cm
Hence, for every 1 cm on the map 100000 cm is covered on the land.
Take the distance on the map for 20 km be x
Hence, 1:100000:: x: 2000000 cm
In order to solve this ratio, you must multiply the extremes and the moderates (nears).
Hence, 2000000×1=100000×x [1km=100000 cm]
Hence, 2000000= 100000x
Hence, x=2000000/100000 cm
Hence, x=20 cm
Hence, 20 cm on the map
Jeremy is painting his room over the
summer. Here are 4 different wall
colors and 3 different trim colors.
How many different ways can he
paint his room?
Answers
Answer:
Jeremy has 12 ways of painting his room.
He has 4 different wall colors and 3 different trim colors, so, if we want to know how many ways does he have to paint his room, we only need to multiply:
4 * 3 = 12
That's why he has 12 ways of painting his room. That's because for each of the 4 different wall colors, there are 3 trim colors he can use.
Answer: 12 different ways
Step-by-step explanation:
The question is asking for a combination of a wall color and a trim color because his room required one wall color and one trim color.
In this case, combination will be the number of first kind multiplies with the second kind. This is similar to sketching a tree diagram but instead, we will be using numerical method which will be quicker.
If you are still confused, I will provide some examples.
You have 5 kind of bread and 4 kind of toppings, there will be 20 different ways to buy a pair (5×4=20)You have 5 different shoes, 3 different laces, and 2 different tops, there will be 30 different ways to match (5×3×2=60)This also applies to your question. You have 4 different wall colors and 3 different trim colors.
4×3=12
You have 12 different ways to paint the room
