The functions are inverses if the reverse of every ordered pair on the f(x) list is on the g(x) list.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

f(x) = 3x - 5

Here, g(x) is not given clearly.

But we can identify the given function as an inverse of each other.

Let's suppose the ordered pairs are:

[x, f(x)] and [x, g(x)]

The functions are inverses if the reverse of every ordered pair on the f(x) list is on the g(x) list.

f(0) = -5 so for (0, -5) on the f(x) list then (-5,0) must be on the g(x) list

f(1) = -2 so for (1, -2) on the f(x) list then (-2, 1) must be on the g(x) list

f(2) = 1 so for (2, 1) on the f(x) list then (1, 2) must be on the g(x) list

Let's suppose:

g(x) = (x+5)/3

g(-5) = 0

g(-2) = 1

g(1) = 2

So the ordered pair (-5, 0), (-2, 1), and (1, 2) are in the list of g(x).

Thus, the functions are inverses if the reverse of every ordered pair on the f(x) list is on the g(x) list.

Step-by-step explanation:

Answer:

a) 23 °C

b) 5.81 m² (2 dp)

Step-by-step explanation:

This set of data is presented as a Dot Plot.

The frequency (how often a data value occurs) is represented by the number of dots above each data value.

For example, in this dot plot, there are 3 dots above the data value 21 °C and so this means that there are three of this particular data value in the set of data.

To find the mean, we need to multiply each data value by its frequency, add them up, then divide by the total frequency.

[tex]\begin{aligned}\textsf{mean}&=\dfrac{3 \times 21+1 \times 22+2\times 23+5\times 24+1\times 25}{3+1+2+5+1}\\\\ & = \dfrac{63+22+46+120+25}{12}\\\\& = \dfrac{276}{12}\\\\&=23^{\circ} \sf C\end{aligned}[/tex]

This set of data is presented as a stem and leaf diagram, where the units and tenths are split.  The units column is the 'stem' and the tenths become the 'leaf'.

Therefore, the first row of this stem and leaf diagram represents 2 data values: 4.3 and 4.8

To find the mean, sum the data values, then divide by the total frequency.

To find the total frequency, simply count the number of values in the leaf part of the diagram.

Data values = 4.3, 4.8, 5.1, 5.1, 5.2, 5.5, 5.7, 6.6, 6.9, 7.3, 7.4

Total frequency = 11

[tex]\begin{aligned}\textsf{mean} &=\dfrac{4.3 + 4.8 + 5.1+5.1+5.2+5.5+5.7+6.6+6.9+7.3+7.4}{11}\\ & = \dfrac{63.9}{11}\\\\& = 5.81\:\textsf{(2 dp)}\end{aligned}[/tex]

[tex]k - 3 = - 8[/tex]

[tex]k = - 5[/tex]

Answer:

45.35

Step-by-step explanation:

Because there are 3 numbers to the right of the decimal point, this number has 3 decimal places. This question wants you to alter the number so that it has only 2 numbers to the right of the decimal. You can't just totally ignore the numbers you want to eliminate, so rounding rules need to be applied.

First, identify the number in the second decimal place position. If the number to the right of this position (the third decimal position) is in the range of 5 - 9, you must add 1 to the second decimal place value. Then, you can drop the numbers after the second decimal place. If the number to the right is 0 - 4, you can simply drop it the value and all the other values to the right.

In this case, the second decimal place has a value of 4. The number to the right is 8. Because 8 is within the 5 - 9 range, add 1 to 4 to get a new decimal value of 5. Finally, drop all the numbers to the right of the new second decimal place value. This leaves you with your answer: 45.35.

The polynomial is a quadratic function, and the completely factored expression of 2x^2 - 9x + 7 is (2x -7)(x - 1)

The polynomial expression is given as:

2x^2 - 9x + 7

Expand

2x^2 - 9x + 7 = 2x^2- 2x - 7x + 7

Factorize the above expansion

2x^2 - 9x + 7 = 2x(x - 1) - 7(x - 1)

Factor out x - 1

2x^2 - 9x + 7 = (2x -7)(x - 1)

Hence, the completely factored expression of 2x^2 - 9x + 7 is (2x -7)(x - 1)

Step-by-step explanation:

if the same equation equals 2 different numbers then therefore there is no solution.

Answer:

24 cubes

Step-by-step explanation:

You can figure this a couple of ways.

I usually find it easiest to figure in terms of the number of cubes each dimension represents. The vertical dimension (3/2 cm) is the length of 3 cubes; the front-back dimension (2 cm) is the length of 4 cubes, and the width (1 cm) is the length of 2 cubes.

The total number of cubes required is the product of the dimensions in cube-lengths: 3×4×2 = 24 cubes.

Answer:

Step-by-step explanation:

Your after-tax income is the gross pay less the amount that is paid to taxes. The monthly income is 1/12 of the annual amount.

__

The tax is the taxed amount multiplied by the tax rate.

  taxes = $45,000 × 15% = $6,750

The after-tax income is the income less the taxes:

  after-tax income = $45,000 -6,750 = $38,250

The monthly income is 1/12 of this amount:

  monthly income = annual income/12 = $38,250/12 = $3,187.50

[tex]f^{-1}(13) = 2[/tex].

Step-by-step explanation:

For function [tex]f[/tex], the notation [tex]f(2) = 13[/tex] means that when the input to the function is [tex]2[/tex], the output would be [tex]13[/tex].

The inverse function of a one-to-one function [tex]f[/tex] is commonly denoted as [tex]\!f^{-1}[/tex].

The inverse function undoes the action of the original function. In this question, [tex]f[/tex] maps [tex]2[/tex] to [tex]13[/tex]. Thus, [tex]f^{-1}[/tex] would need to map [tex]13\![/tex] back to [tex]2\![/tex]. Therefore, [tex]f^{-1}(13) = 2[/tex] should be the corresponding input and output values.

It's about 962.89 cm^2

Answer:

962.89cm^2

Step-by-step explanation:

So, in this question, you have to find the radius of the circle because the area of a circle = πr^2. So first, you find r^2, and to do that, you divide 110 by π and you get 35.0140874802, now divide that by two and you get 17.5070437401 and that is your radius. Now, you do 17.5070437401 to the power of 2 (17.5070437401^2) and you get 306.496580518. Now multiply that by π and you get 962.89.

Explanation:

If the employee has worked there for 20 years and for every year its 50 dollars. That would mean its 50x20 which eqauls 1000.

The monthly income in the first year after retirement is $1000.

Average monthly income is the amount you earn each month. Depending on your source of income, you can subtract insurance payments, rent allowances and other costs, such as federal and state taxes, from your total income every month. Net worth is your debt subtracted from your total assets.

Given that, Janet is retiring after working for a major department store for 20 years. The company offered her a flat retirement benefit of $50 per year for each year of service.

After working for 20 years, Janet has decided to retire from her job at a major department store.

The company has offered her a flat monthly retirement benefit of $50 for each year of service, which means that her monthly income in the first year after retirement would be $50 multiplied by 20, which is equal to $1000.

Hence, the monthly income in the first year after retirement is $1000.

Step-by-step explanation:

You can rewrite the given log expressions to express them in terms of ln(a), ln(b), and ln(c). Then substituting the given values will produce the value of the expression.

Or, you can define the variables 'a', 'b', and 'c' and let your calculator compute these directly.

  [tex]\ln\left(\dfrac{a^4}{b^4c^{-2}}\right)=4\ln(a)-(4\ln(b)-2\ln(c))=4\cdot2-4\cdot3+2\cdot5=\boxed{6}[/tex]

  [tex]\ln\left(\sqrt{b^{-2}c^4a^2}\right)=\dfrac{1}{2}\left(-2\ln(b)+4\ln(c)+2\ln(a)\right)=\ln(a)-\ln(b)+2\ln(c)\\\\=2-3+2\cdot5=\boxed{9}[/tex]

  [tex]\dfrac{\ln(a^1b^2)}{\ln(bc)^2}=\dfrac{\ln(a)+2\ln(b)}{(\ln(b)+\ln(c))^2}=\dfrac{2+2\cdot3}{(3+5)^2}=\dfrac{8}{64}=\boxed{\dfrac{1}{8}}[/tex]
