Type the expression that results from the following series of steps:
Start with x, times by 6, then add y.​

Answer:

C

Step-by-step explanation:

Step-by-step explanation:

Given

sin(α+β) cos(α-β) +cos(α+β) sin(α -β)

We can see it is in the formula of

sin(A + B) = sinA cosB + cosA sinB

So now

Sin ( α + β + α - β)

= sin 2α

Or we can write sin2α as

= 2 sin α * cos α

Hope it will help :)❤

Complete Question:

Find the coordinates of the point after the described reflection. Give the distance between the point and its reflection. R(-5, 8) is reflected across the x-axis _____________.

Answer:

[tex](a)[/tex] [tex]R' = (-5,-8)[/tex]

[tex](b)[/tex] The distance is 16 units

Step-by-step explanation:

Given

[tex]R = (-5,8)[/tex]

Solving (a): Reflection across x-axis

The rule is:

[tex]R(x,y) ==> R(x,-y)[/tex]

So, the reflection of [tex]R = (-5,8)[/tex] is:

[tex]R' = (-5,-8)[/tex]

Solving (b): The distance between R and R'

Distance (d) is calculated as:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

Where:

[tex]R = (-5,8)[/tex] ---- [tex](x_1,y_1)[/tex]

[tex]R' = (-5,-8)[/tex] --- [tex](x_2,y_2)[/tex]

This gives:

[tex]d = \sqrt{(-5- -5)^2 + (-8- 8)^2}[/tex]

[tex]d = \sqrt{(0)^2 + (-16)^2}[/tex]

[tex]d = \sqrt{256}[/tex]

[tex]d = 16[/tex]

The distance is 16 units

Answer:

1.230 euros

Step-by-step explanation:

De la pregunta anterior se nos dice que:

Yolanda compró un coche por 8.200 euros. Lo ha pagado en tres partes.

Paso 1

Sea el porcentaje de la suma total de dinero = 100%

Primero pagó el 60% del valor del auto, luego el 25% y finalmente el resto.

Dejemos que el resto esté representado por x

Por eso;

Primera parte + Segunda parte + Tercera parte = 100%

60% + 25% + x = 100%

x = 100% - (60% + 25%)

x = 100% - 85%

x = 15%

Paso 2

¿Cuánto pagó Yolanda la última vez?

La última vez = Tercera parte y esto se calcula como:

15% de 8.200 euros

= 15/100 × 8.200 euros

= 1.230 euros

Yolanda pagó 1.230 euros la última vez.

Answer:

11 feet

Step-by-step explanation:

All the sides of a square are equal

the area of a square = length²

121 ft² = length²

to determine the length find the square root of the area, 121

√121 = 11 feet

Answer:

[tex]Column\ 1: 4y^2[/tex]

[tex]Column\ 2: 6x^3+4xy+3y[/tex]

Step-by-step explanation:

Given

[tex]24x^3y^2+16xy^3+12y^3[/tex]

Required

Determine the product from the given column

[tex]24x^3y^2+16xy^3+12y^3[/tex]

Factor our [tex]y^2[/tex]

[tex]24x^3y^2+16xy^3+12y^3 = y^2(24x^3 + 16xy + 12y)[/tex]

Factor out 4

[tex]24x^3y^2+16xy^3+12y^3 = 4y^2(6x^3 + 4xy + 3y)[/tex]

So: the factors are:

[tex]4y^2[/tex] and [tex]6x^3 + 4xy + 3y[/tex]

This gives:

[tex]Column\ 1: 4y^2[/tex]

[tex]Column\ 2: 6x^3+4xy+3y[/tex]

Answer:

4 1/6 inches

Step-by-step explanation:

A triangle has sides of LaTeX: 1\frac{1}{6}1 1 6 inches, LaTeX: 1\frac{1}{3}1 1 3 inches, and LaTeX: 1\frac{2}{3}1 2 3 inches. What is the perimeter of the triangle? Make sure your answer is in simplest form.

Perimeter of Triangle = Side a + Side b + Side c

Perimeter of the Triangle =

( 1 1/6 + 1 1/3 + 1 2/3) inches

Lowest common denominator = 6

= 1 + 1 + 1 +(1/6 + 1/3 + 2/3)

= 3 + (1 + 2 + 4/6)

= 3 + 7/6

= 3 + 1 1/6

= 4 1/6 inches

Answer:

90 miles

Step-by-step explanation:

There's more than one way in which to do this.  I have chosen to convert '180 minutes' to '3 hours.'

Since distance = rate times time, we have here:

distance traveled in 180 minutes = (30 mph)(3 hr) = 90 miles

Answer:

answer is c 15904.48

Step-by-step explanation:

y=a(l-r )   Y=18000(1 - .06) = 15904.48

Answer:25$

Step-by-step explanation:

Answer: x=50°

Step-by-step explanation:

For this question, you have to first find out whether you are using Sin, Cos or Tan.

To help you find out which one you are using you can use SOH CAH TOA to help you:

SOH-the 'S' is for Sin then the 'O' and the 'H' is for Opposite over Hypotenuse.

CAH-the 'C' is for Cos and then the 'A' and the 'H' is for Adjacent over Hypotenuse.

TOA-the 'T' is for Tan then the 'O' and the 'A' is for Opposite over Adjacent.

In this, because you have the Hypotenuse (the length opposite the right angle) and the Adjacent (the length next to the angle you are finding) you would be using Cos.

So first you would write:

Cos x=59/91

But then because you want x on it's own you would do the inverse. So, instead of multiplying x by cos you would have to do cos-1 (the inverse of cos). This would be written as:

x=cos-1 59/91

To get the answer you would have to put this in your calculator.

So x=50°

Hope this helps :)

The most frequent value = mode

The middle value = median

The average = mean

The difference between the lowest and highest value = range

Answer:

Mode is the most frequent value

Mean is the average

Median Is the middle value

Range is the difference between etc...

Because 19 is being divided, you have to do the opposite. What's the opposite of division? Multiplication. So multiply 19 to -7, then get rid of the 19 on the x's side(cuz it was cancelled out). Now you should have x<-133. In case you don't know, positive times negative equals negative, but negative times negative equals positive.

Answer:

Fred needs 3 cups of sugar to make 4 batches

Fred needs 3/8 cups of sugar to make 1/2 batches

Step-by-step explanation:

1 batch of cookies = 3/4 cups of sugar

how many cups of sugar does Fred need to make 4 batches

Let x = cups of sugar needed

Batches : Cups of sugar

1 : 3/4 = 4 : x

1 ÷ 3/4 = 4/x

1 * 4/3 = 4/x

4/3 = 4/x

Cross product

4 * x = 3 * 4

4x = 12

x = 12/4

x = 3 cups of sugar

Fred needs 3 cups of sugar to make 4 batches

how many cups of sugar does Fred need to make 1/2 batches?

Let x = cups of sugar needed

Batches : Cups of sugar

1 : 3/4 = 1/2 : x

1 ÷ 3/4 = 1/2 ÷ x

1 * 4/3 = 1/2 * 1/x

4/3 = 1/2x

Cross product

4 * 2x = 3 * 1

8x = 3

x = 3/8 cups of sugar

Fred needs 3/8 cups of sugar to make 1/2 batches
