Answer:

Tax amount: $7.36

Tax rate: 5.84%

Step-by-step explanation:

First, we have to find the tax amount by taking

$133.36 - $126 = $7.36

Tax amount: $7.36

To find the tax rate, we take

7.36 divided by 126, times 100 = 5.84%

Tax rate: 5.84%

So,

Tax amount: $7.36

Tax rate: 5.84%

The most accurate comment about the graph  data is: "China's steel production is increasing while its major competitors' production is declining."

Academics are using graphs to logically chart or graphically depict events or quantities. A graph point is a common way to depict how different things interact. The non-linear storage structure known as a graph is made up of nodes, also referred to as vertices, and lines. Glue ought to be used to connect the edges, also known as nodes , respectively.  (4.5).

Here,

The most accurate comment about the data is: "China's steel production is increasing while its major competitors' production is declining."

This is because the graph shows that China's steel production has been steadily increasing since the early 2000s, while the steel production of other major producers such as Japan, the United States, and Germany has been declining or stagnant. This trend is particularly evident after the global financial crisis of 2008-2009.

While it is true that Japan's steel production has increased and shows no signs of decreasing, this comment does not address the overall trend of declining steel production among major producers.

The other two comments are not accurate. The statement "By 2009, China’s tons of steel produced per US million ($) GDP was 50, about 10 tons less than Japan’s all-time high" is not supported by the graph, as there is no information about tons of steel produced per US million ($) GDP on the graph.

Using percentages we know that the rate of commission of the salesperson based on the net sales is 15.5%.

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and sometimes "pc" is also used, the percent symbol, "%," is frequently used to indicate it.

A % is a number without boundaries and without a standard measurement.

So, calculate as follows:

5880/100 * 11.5 = 676.2

Now,

5880 - 676.2 = 5,203.8

Now, calculate the percentage as follows:

806.59/5,203.8 * 100

15.5%

Therefore, using percentages we know that the rate of commission of the salesperson based on the net sales is 15.5%.

Answer:

p = 1

Step-by-step explanation:

since (p, 2p + 1) is a solution then it makes the equation true.

substitute x = p and y = 2p + 1 into the equation and solve for p

11p - 2(2p + 1) = 5 ← distribute parenthesis and simplify left side

11p - 4p - 2 = 5

7p - 2 = 5 ( add 2 to both sides )

7p = 7 ( divide both sides by 7 )

p = 1

Answer:

Below

Step-by-step explanation:

I suppose you are looking for a solution to the system of equations

  since both equations are equal to 'y' they are equal:

 2x+3  = -3x+3       add 2x to both sides of the equation

 5x + 3 = 3              subtract 3 from both sides

 5x = 0            so x = 0

  if x =0 then find y    y = 2(0) + 3 = 3

       the solution is (0,3)

Answer:

y = 4x - 3

Step-by-step explanation:

y = mx + b

The m is the slope and the b is the y-intercept.

The slope is 4.  If you start at the point (0,-3) and go up 4 units and then 1 unit to the right, you will be back on the line at point (2,4) The slope is the rise over the run.  The rise is 4 and the run is 1.  4/1 = 4.

The slope (m) is 4.

The y-intercept is where the line crosses the y axis.  It crosses at (0,-3)

The y-intercept (b) is -3

Plug 4 in for m and -3 in for b

y = mx + b

y = 4x -3

Answer:

[tex]y = 4x - 3[/tex]

Step-by-step explanation:

we need to find out the equation of the function that is graphed. From the given graph we can see that the line passes through points (0,-3) and (2,5) . So we can find out the slope of the line as ,

[tex]\implies m =\dfrac{y_2-y_2}{x_2-x_1}=\tan\theta\\[/tex]

[tex]\implies m =\dfrac{-3-5}{0-2} \\[/tex]

[tex]\implies m =\dfrac{-8}{-2} \\[/tex]

[tex]\implies \mathfrak{ m = 4 }\\[/tex]

Now we may use point slope form of the line to find out the equation of the line as,

[tex]\implies y - y_1 = m(x-x_1) \\[/tex]

[tex]\implies y -(-3) = 4(x-0) \\[/tex]

[tex]\implies y +3 = 4x\\[/tex]

[tex]\implies \underline{\underline{ y = 4x -3}} \\[/tex]

Therefore, we have proved that the value of the expression

(3/5x²-0.4cy-1.5y+1)-(y²-2/5xy+0.6x²) doesn't depend on x.

In mathematics, addition, multiplication, and division are necessary. They result in the following when combined: An equation, some data, and a mathematical function Values, parameters, and mathematical operations like additions, subtractions, multiplications, and divisions can all be found in a declaration of fact. Different phrases and words can be compared and evaluated.

Here,

To prove that the value of the expression doesn't depend on x, we need to show that the x-term disappears when we simplify the expression.

Starting with:

(3/5x² - 0.4cy - 1.5y + 1) - (y² - 2/5xy + 0.6x²)

Distributing the negative sign in the second set of parentheses:

3/5x² - 0.4cy - 1.5y + 1 - y² + 2/5xy - 0.6x²

Rearranging the terms by collecting like terms, we get:

(3/5 - 0.6)x² + (2/5y - 0.4c)y - y²- 1.5y + 1

Simplifying further, we get:

(-0.1)x² + (0.4y - 0.4c)y - (y² + 1.5y - 1)

Notice that there is no x-term in the final expression, which means that the value of the expression doesn't depend on x.

Therefore, we have proved that the value of the expression (3/5x²-0.4cy-1.5y+1)-(y²-2/5xy+0.6x²) doesn't depend on x.

E(-7, -5) → E' (-7/5, -1)

Resizing an item uses a transformation called dilation. Dilation is used to enlarge or shorten the structures. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. The initial form should be stretched or contracted during a dilatation.

Given:

Answer: To find the principal value of arctan(-1.44) to the nearest minute, we first need to find the value of arctan(-1.44) in radians.

We can use the arctan function in a mathematical software or calculator to find the result. The value of arctan(-1.44) in radians is approximately -0.8623.

Next, we convert the result from radians to minutes, by multiplying the radians by 180/π and then multiplying the result by 60.

-0.8623 * 180/π * 60 = -50.47 minutes

So the principal value of arctan(-1.44) to the nearest minute is approximately -50 minutes.
