Answer:

C

Step-by-step explanation

The mapping diagram which shows the inverse of R(x) is Option (C).

A function is a special type of relation in which each element of the domain is paired with exactly one element in the range . A mapping diagram shows how the elements are paired. Its like a flow chart for a function, showing the input and output values. A mapping diagram consists of two parallel columns.

To identify the mapping diagram for inverse of a function, we simply just change the values of first set of columns into the second set of columns.

This is because if [tex]f(x) = y[/tex] , then  [tex]f^{-1}(y) = x[/tex]

For the given function R(x) , values are 6,7,8,9 in first column and 9,10,11,12 in the second column . Thus for the inverse function,  6,7,8,9  will be in the second column and 9,10,11,12 will be in the first column.

From the given Options, Option (C) is the correct mapping of inverse of R(x).

Thus, the mapping diagram which shows the inverse of R(x) is Option (C).

EXPLANATION

The base angles of an isosceles triangle are equal.

This implies that:

8y-7=73°

Add 7 to both sides:

8y=73+7

8y=80°

y=10°

Interior angles of a triangle sums up to 180°

73+73+6x+4=180

150+6x=180

6x=180-150

6x=30

Divide both sides by 6

x=5

The equation y = 11x + 1 is a linear equation. All three ordered pairs, (0, 1), (1, 12), and (-1, -10), satisfy this equation.

The equation y = 11x + 1 represents a linear equation. To determine which ordered pairs satisfy this equation, we substitute the x and y values into the equation and check if the equation holds true. Let's check each option:

Based on the calculations, we can see that all three ordered pairs are valid solutions for y = 11x + 1.

Answer: This is some information I have gathered to help you since I cannot answer this directly sin θ + (cot θ)(cos θ)  

= sin θ + (cos θ / sin θ)(cos θ)  

= sin θ + cos² θ / sin θ  

Since cos² θ = 1 - sin² θ,

Answer:

the answer on e2020 is 12.

The required answer is,

f(x) + f(x) + f(x) = 3ax² + 3bx + 3c

3f(x) = 3ax² + 3bx + 3c

3f(2) = 12a  + 6b + 3c

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Now let the function be,

f(x) = ax² + bx + c

To find,

f(x) + f(x) + f(x)

we have,

f(x) + f(x) + f(x) = (ax² + bx + c) +  (ax² + bx + c) +  (ax² + bx + c)

⇒ f(x) + f(x) + f(x) = 3(ax² + bx + c)

or, f(x) + f(x) + f(x) = 3ax² + 3bx + 3c

Similarly,

3f(x) = 3(ax² + bx + c)

or, 3f(x) = 3ax² + 3bx + 3c

now to find f(2), put x =  2 in f(x). we get,

f(2) = a2² + b2 + c

or, f(2) = 4a + 2b + c

Therefore,

3f(2) = 3(4a + 2b + c)

or, 3f(2) = 12a  + 6b + 3c

hence, the required answer is,

f(x) + f(x) + f(x) = 3ax² + 3bx + 3c

3f(x) = 3ax² + 3bx + 3c

3f(2) = 12a  + 6b + 3c

I'd say C Sets 2 and 3 contain outliers.

Step-by-step explanation:

Set 2 has an outlier of 90, while set 3 has an outlier of 40. 40 isn't as much of an outlier as 90 is, so I'm not absolutely sure. Cmakes the most sense though.

Answer: Third option.

Step-by-step explanation:

The standard deviation increases as we have more values that are far away from the mean.

For example, in data set 2, we can see that most of hour points are between 38 and 49, but we also have a point with a value of 90, so we may expect that this data set has a big standard deviation.

The data set 3 is similar, most of our points are between 24 and 31, and we have a value that is on 40, so again we have an outlier that increases the value of the standard deviation.

Noticing it we can conclude that data set 2 and data set 3 have a greater standard deviation than set 1.

The correct option is the third option.

-schools

-governmental departments (EPA, Department of Homeland Security, etc)

-government employee paychecks

And SOMETIMES:

Taxes are used to fund government services, reduce income inequalities, and support state and local government activities.

Taxes are used for a variety of purposes. They are primarily used to fund government services such as military, police, education, infrastructure, and social security. Taxes are also used to reduce income and wealth inequalities by transferring income to lower income groups. Additionally, taxes are used to support state and local government activities and services.

For example, in the United States, the federal government raises revenue through income taxes, corporate earnings taxes, and sales taxes on goods such as gasoline, alcohol, and tobacco. State and local governments also collect taxes, including income, property, and sales taxes, which fund activities like maintaining public parks and providing a police force.

Overall, taxes play a crucial role in financing government operations and essential public services that benefit communities.

(C) d=1

EXPLANATION

The given equation is

[tex] \frac{ - 3d}{ {d}^{2} - 2d - 8} + \frac{3}{d - 4} = \frac{ - 2}{d + 2} [/tex]

Factor the first fraction to get,

[tex] \frac{ - 3d}{(d + 2)(d - 4)} + \frac{3}{d - 4} = \frac{ - 2}{d + 2} [/tex]

Multiply through by (d+2)(d-4)

[tex] - 3d + 3(d + 2) = - 2(d - 4)[/tex]

Expand:

[tex] - 3d + 3d + 6 = - 2d + 8[/tex]

[tex] 6 = - 2d + 8[/tex]

[tex]6 - 8= - 2d[/tex]

[tex] - 2 = - 2d[/tex]

divide both sides by -2

[tex]d = 1[/tex]

The correct answer is (B) [tex]\( d = -2 \)[/tex] and [tex]\( d = 4 \)[/tex].

To find the solution to the given quadratic equation, we can factor it or use the quadratic formula. The equation is not provided in the conversation, but based on the options given, it seems that the equation could be in the form [tex]\( (d - a)(d - b) = 0 \)[/tex], where [tex]a[/tex] and [tex]b[/tex]are the roots of the equation.

The quadratic equation can be written as [tex]\( d^2 - (a+b)d + ab = 0 \)[/tex]. To have the sum of the roots [tex]\( a + b \)[/tex] equal to 0 and the product of the roots [tex]\( ab \)[/tex] equal to -8, we can set up the following system of equations:

1. [tex]\( a + b = 0 \)[/tex]

2. [tex]\( ab = -8 \)[/tex]

From equation 1, we can express [tex]\( b \)[/tex] in terms of [tex]\( a \): \( b = -a \).[/tex]

Substituting [tex]\( b \)[/tex] into equation 2, we get:

[tex]\( a(-a) = -8 \)[/tex]

[tex]\( -a^2 = -8 \)[/tex]

[tex]\( a^2 = 8 \)[/tex]

Taking the square root of both sides, we find:

[tex]\( a = \pm\sqrt{8} \)[/tex]

[tex]\( a = \pm2\sqrt{2} \)[/tex]

Since [tex]\( b = -a \),[/tex] we have:

[tex]\( a = 2\sqrt{2} \) and \( b = -2\sqrt{2} \)[/tex]

[tex]\( a = -2\sqrt{2} \) and \( b = 2\sqrt{2} \)[/tex]

However, these are not the exact values given in the options. We need to find the exact integer values for [tex]a[/tex] and [tex]b[/tex]. Since the product [tex]\( ab \)[/tex] is -8, we can look for two numbers that multiply to -8 and add up to 0. These numbers are -2 and 4.

Therefore, the solutions to the equation are [tex]\( d = -2 \)[/tex] and [tex]\( d = 4 \)[/tex], which corresponds to option (B).

Answer:

a) 3,6,9,12,15,..

b) Common Ratio is 3

c) Recursive Formula : aₙ= aₙ₋₁ + d where a₁=3 and d= 3

Step-by-step explanation:

a) Create your own arithmetic sequence. Write out the first 3 terms.

Consider the sequence: 3,6,9,12,15,..

a₁ = 3

a₂ = 6

a₃ = 9

b) What is the common difference of your sequence?

6-3 = 3

9-6 = 3

12 -9 =3

So, common difference is 3

c) Write the recursive formula representing your sequence.

a₁ = 3

a₂ = aₙ₋₁ + d

   = a₁ + d

   = 3+ 3 = 6

a₃ = aₙ₋₁ + d

    = a₂ + d

   = 6+3 = 9

so, recursive formula is aₙ = aₙ₋₁ + d where a₁ = 3 and d= 3

An example of an arithmetic sequence can be created with a starting value (a1) of 2 and a common difference (d) of 3. The sequence's terms would be 2, 5, 8, etc. Its recursive formula would be a1 = 2; a_n = a_(n–1) + 3.

Let's create an arithmetic sequence, starting with the first term (a1) of 2 and a common difference (d) of 3. So, the first three terms of the sequence would be 2, 2+3=5, and 5+3=8.

The common difference of this arithmetic sequence is 3 as each term is 3 greater than the previous term.

The recursive formula for this sequence is a1 = 2; a_n = a_(n–1) + 3. What this formula means is that the first term is 2, and each subsequent term (an) is the previous term (an-1) added to the common difference (3).

To find the correct answers, we need to find a equation that meet the following charactheristics:

From the graph we can se that the function:

- Has a negative slope (is decreasing)

- Pass throught the points: (-1,5) and (3,2)

Now, discarding from the given options, we have:

[tex]y-2=-0.75(x-3)[/tex]

We have that the coefficient of the linear term is negative (-0.75), so, the slope is negative (the function is decreasing).

Evaluating the points, we have:

Evaluating (-1,5)

[tex]5-2=-0.75(-1-3)[/tex]

Evaluating (3,2):

[tex]2-2=-0.75(3-3)[/tex]

[tex]0=-0.75(0)[/tex]

[tex]0=0[/tex]

We have that the equation is satisfied, so,  the line pass  through the given points.

Hence, we have that the equation A is an equation of the line shown.

[tex]y-5=-0.75(x-1)[/tex]

We have that the coefficient of the linear term is negative (-0.75), so, the slope is negative (the function is decreasing).

Evaluating the points, we have:

Evaluating (-1,5)

[tex]5-5=-0.75(-1-1)[/tex]

[tex]0=-3.5[/tex]

Hence, we have that since the equation is not satisfied, the line shown is not passing  through the point (-1,5) meaning that the equation is not an equation of the line shown.

So,  we have that the equation B is not equation of the line shown.

[tex]y-3=-0.75(x-2)[/tex]

We have that the coefficient of the linear term is negative (-0.75), so, the slope is negative (the function is decreasing).

Evaluating the points, we have:

Evaluating (-1,5)

[tex]5-3=-0.75(-1-2)[/tex]

[tex]2=-0.75(-3)[/tex]

[tex]2=2.25[/tex]

Hence, we have that since the equation is not satisfied, the line shown is not passing  through the point (-1,5) meaning that the equation is not an equation of the line shown.

So, we have that the equation B is not equation of the line shown.

(assuming you committed a mistake writing the options and the equality sign is missing)

[tex]y-5=-0.75(x+1)[/tex]

We have that the coefficient of the linear term is negative (-0.75), so, the slope is negative (the function is decreasing).

Evaluating the points, we have:

Evaluating (-1,5)

[tex]5-5=-0.75(-1+1)[/tex]

[tex]0=-0.75(0)[/tex]

[tex]0=0[/tex]

Evaluating (3,2)

[tex]2-5=-0.75(3+1)[/tex]

[tex]-3=-0.75(4)[/tex]

[tex]-3=-3[/tex]

We have that the equation is satisfied, so,  the line pass  through the given points.

Hence, we have that the equation B is an equation of the line shown.

Finally, we have that the correct options are:
