Answer:
B
Step-by-step explanation:
First, note that the figure is a parallelogram.
The area of a parallelogram is given by:
[tex]A=bh[/tex]
Where b is the base length and h is the vertical height.
The base length is 5+2 or 7, and the vertical height is 2.
Thus:
[tex]A=7(2)\\A=14\text{ in}^2[/tex]
The answer is B.

12x+6=10x+10
12X-10X=10-6
2X=4
X=4÷2=2
Answer:
x = 2
Step-by-step explanation:
Basic proportionality theorem,
[tex]\frac{AB}{BD}=\frac{CB}{BE}\\[/tex]
AB = AD + DB = 4+6 = 10
CB = CE + EB = x + x +1 = 2x +1
[tex]\frac{10}{6}=\frac{2x+1}{x+1}[/tex]
Cross multiply
10*(x+1) = 6*(2x+ 1)
10*x + 10*x = 6*2x + 6*1
10x + 10 = 12x + 6
Subtract 10x from both sides
10x + 10 - 10x = 12x + 6 - 10x
10 = 2x + 6
Subtract 6 form both sides
10 - 6 = 2x + 6 - 6
4 = 2x
Divide both sides by 2
4/2 = 2x/2
2 = x
x = 2

There are 4 chocolate chip cookies and 12 oatmeal cookies in a jar. If you reach in and randomly choose 2 cookies without replacing the first, what is the probability that both will be chocolate chip? 6
Answers
Answer:
A
Step-by-step explanation:
So there are 4 chocolate chips and 12 oatmeal. In total, there are 16 cookies.
The probability of selecting a chocolate chip when you reach in for the first time will be 4/16 or 1/4.
The second time, you reach in, however, there would be one less chocolate chip cookie because you would've pulled one out previously. Thus, the probability is now 3/15 or 1/5.
So, the probability of pulling a chocolate chip cookie consecutively is:
[tex]\frac{1}{4}\cdot\frac{1}{5}=\frac{1}{20}[/tex]

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:
3a - 2b = 9

What is the DOMAIN of the following relation? {(-5,4), (-4,2), (0,2), (1,3), (2,4)}
Answers
Answer:
{-5, -4, 0, 1, 2}
Step-by-step explanation:
The domain is the inputs or the x values
{-5, -4, 0, 1, 2}
Answer:
See below.
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:
{(-5,4), (-4,2), (0,2), (1,3), (2,4)}
So, our domain is:
[tex]\{-5, -4, 0, 1, 2\}[/tex]
Note that the domain is in ascending order.

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.

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]

A students pays of 18 an hour is 4 more than twice the amount of the student earns per hour at an internship enter an solve an equation to find the hourly pay of the intership
Answers
Answer:
the hourly pay fro the internship is $7/hr
Step-by-step explanation:
The statement can be written mathematically as below
[tex]18 = 4 + 2x[/tex]
the hourly rate of the internship is [tex]x[/tex]
solving the equation, we have
[tex]18 = 4 + 2x[/tex]
subtract 4 from both sides of the equation
[tex]18 - 4 = 4 +2x -4[/tex]
[tex]14 = 2x[/tex]
[tex]x = 14/2[/tex]
[tex]x = 7[/tex]
the hourly pay fro the internship is $7/hr
Answer: $7
Step-by-step explanation:
According to the question , we have
$18=4+2 (amount of the student earns per hour at an internship)
Let x be the amount of the student earns per hour at an internship, then the equations will be
18 = 4+2x
Subtract 4 from both sides , we get
14 = 2x
Divide both sides by 2, we get
7 = x
Hence, the hourly pay of the intership was $7 .
Given that \tan\theta =\frac{12}{35}tanθ= 35 12 and that angle \thetaθ terminates in quadrant \text{III}III, then what is the value of \cos\thetacosθ?
Answers
Answer:
[tex]cos\theta = -\frac{12}{37}[/tex]
Step-by-step explanation:
Given
[tex]tan\theta = \frac{35}{12}[/tex]
Quadrant: 3rd
Required
Determine [tex]cos\theta[/tex]
This question will be solved using the Pythagoras theorem
[tex]Hyp^2 = Adj^2 + Opp^2[/tex]
The tangent of an angle is calculated as thus;
[tex]tan\theta = \frac{Opp}{Adj}[/tex]
Comparing
[tex]tan\theta = \frac{35}{12}[/tex] to [tex]tan\theta = \frac{Opp}{Adj}[/tex]
We can conclude that
[tex]Opp = 35[/tex] [tex]Adj = 12[/tex]
Substitute these values in the Pythagoras formula
[tex]Hyp^2 = 35^2 + 12^2[/tex]
[tex]Hyp^2 = 1225 + 144[/tex]
[tex]Hyp^2 = 1369[/tex]
Square root of both sides
[tex]Hyp = \sqrt{1369}[/tex]
[tex]Hyp = 37[/tex]
SInce [tex]\theta[/tex] is in the 3rd quadrant, then
[tex]cos\theta = -\frac{Adj}{Hyp}[/tex]
Where [tex]Adj = 12[/tex] and [tex]Hyp = 37[/tex]
[tex]cos\theta = -\frac{12}{37}[/tex]
