Since the function is linear, we know that it is a line.
Let's use points (2,1) and (4,4) to calculate the slope:
\(m=\frac{4-1}{4-2}\rightarrow m=\frac{3}{2}\)We can use this slope, point (2,1) and the slope-intercept form to find an equation, as following:
\(\begin{gathered} y-1=\frac{3}{2}(x-2) \\ \\ y-1=\frac{3}{2}x-3 \\ \\ \Rightarrow y=\frac{3}{2}x-2 \end{gathered}\)Thereby, our function would be:
\(f(x)=\frac{3}{2}x-2\)To fill the table,
\(\begin{gathered} -2=\frac{3}{2}x-2 \\ \rightarrow0=\frac{3}{2}x \\ \\ \Rightarrow x=0 \end{gathered}\)\(\begin{gathered} f(x)=\frac{3}{2}(-2)-2 \\ \Rightarrow f(x)=-5 \end{gathered}\)The complete table would be:

The data below shows the money Paritosh spends on a weekend. What will be the central angles of each of these categories?with the numbers 40 100 50 50
The central angles for the categories with the numbers 40, 100, 50, and 50 are 60 degrees, 150 degrees, 75 degrees, and 75 degrees, respectively.
To calculate the central angles for each category based on the given numbers 40, 100, 50, and 50, we need to find the proportion of each value to the total sum of all the values. Let's proceed with the following steps:
Step 1: Calculate the total sum of the given numbers: 40 + 100 + 50 + 50 = 240.
Step 2: Find the proportion of each value by dividing it by the total sum and multiplying it by 360 (since a full circle has 360 degrees).
Central angle for the first category: (40/240) * 360 = 60 degrees.
Central angle for the second category: (100/240) * 360 = 150 degrees.
Central angle for the third category: (50/240) * 360 = 75 degrees.
Central angle for the fourth category: (50/240) * 360 = 75 degrees.
The central angles for each category based on the given numbers are 60 degrees, 150 degrees, 75 degrees, and 75 degrees, respectively.
These central angles represent the relative proportions of each category's spending in relation to the total spending. They can be used to create a pie chart or visualize the distribution of expenses in a circular graph.

The angle between 0 and 2pi in radians that is coterminal with the angle 34/7pi in radians is
.
The angle between 0 and 2pi in radians that is co-terminal with the angle 34/7pi in radians is 20/7π.
To find the angle between 0 and 2π in radians that is co-terminal with the angle 34/7π in radians, we need to first understand what co-terminal angles are.
Co-terminal angles are angles that share the same initial and terminal sides, but differ by a multiple of 360°. In radians, they differ by a multiple of 2π.
To find the co-terminal angle, we need to add or subtract a multiple of 2π from the given angle until we get an angle between 0 and 2π. We can do this using the following formula:
Co-terminal angle = θ ± 2nπ Where θ is the given angle and n is an integer that represents the number of full rotations (360° or 2π radians) we add or subtract.
To find the co-terminal angle with 34/7π, we need to subtract 2π until we get an angle between 0 and 2π:
34/7π - 2π = (34/7 - 14/7)π = 20/7π.
Now, we have an angle of 20/7π that is co-terminal with 34/7π and is between 0 and 2π radians.
Therefore, the answer is 20/7π.

Using the z-distribution, the 95% confidence interval of the population mean is: (17.5, 24.5).
What is a z-distribution confidence interval?The confidence interval is:
\(\overline{x} \pm z\frac{\sigma}{\sqrt{n}}\)
In which:
\(\overline{x}\) is the sample mean.z is the critical value.n is the sample size.\(\sigma\) is the standard deviation for the population.In this problem, we have a 95% confidence level, hence\(\alpha = 0.95\), z is the value of Z that has a p-value of \(\frac{1+0.95}{2} = 0.975\), so the critical value is z = 1.96.
For this problem, the other parameters are:
\(\overline{x} = 21, \sigma = 26.8, n = 225\)
Hence the bounds of the interval are:
\(\overline{x} - z\frac{\sigma}{\sqrt{n}} = 21 - 1.96\frac{26.8}{\sqrt{225}} = 17.5\)
\(\overline{x} + z\frac{\sigma}{\sqrt{n}} = 21 + 1.96\frac{26.8}{\sqrt{225}} = 24.5\)

When an object is weighed on a scale, the number displayed may vary from the object’s actual weight by at most 0.4 pounds. The scale says the object weighs 125.8 pounds. Part A: Write an absolute value inequality that describes the range of the actual weight of the object. Use the variable w to represent the actual weight of the object. Part B: Solve the absolute value inequality for w. Express your answer as a compound inequality.
The compound inequality that represents the range of the actual weight of the object is 125.4 ≤ w ≤ 126.2.
Part A: The absolute value inequality that describes the range of the actual weight of the object is:
|w - 125.8| ≤ 0.4
Part B: To solve the absolute value inequality, we can break it down into two separate inequalities:
w - 125.8 ≤ 0.4 and - (w - 125.8) ≤ 0.4
Solving the first inequality:
w - 125.8 ≤ 0.4
Add 125.8 to both sides:
w ≤ 126.2
Solving the second inequality:
-(w - 125.8) ≤ 0.4
Multiply by -1 and distribute the negative sign:
-w + 125.8 ≤ 0.4
Subtract 125.8 from both sides:
-w ≤ -125.4
Divide by -1 (note that the inequality direction flips):
w ≥ 125.4
Combining the solutions, we have:
125.4 ≤ w ≤ 126.2
The object is 125.4 ≤ w ≤ 126.2.

Write f(x)= -x3+4x2 into the factor form given the zeros 0 (multiplicity of 2) and 4 (multiplicity of 1).
The equivalent polynomial function is f(x) = -x^3 + 4x^2 = x^2(x - 4)(x^2)
Determining the polynomial given the multiplicity and zeros.To find the factor form of the given polynomial function f(x) = -x^3 + 4x^2, we need to use the zeros given as inputs. We know that the zeros of a function are the values of x that make the function equal to zero.
We are given two zeros: x = 0 with a multiplicity of 2, and x = 4 with a multiplicity of 1. This means that (x - 0) is a factor of multiplicity 2, and (x - 4) is a factor of multiplicity 1.
To find the other factor, we can use polynomial long division or synthetic division. Since (x - 0) is a factor of multiplicity 2, we will divide f(x) by (x - 0)^2 or (x - 0)(x - 0).
Using polynomial long division or synthetic division, we get:
-x + 4
____________
x^2 | -x^3 + 4x^2 + 0x + 0
-(-x^3)
_______
0x^2
0x^2
______
4x^2
-4x^2
______

Therefore, we get:
f(x) = -x^3 + 4x^2 = x^2(x - 4)
So the factor form of the given polynomial function is:
f(x) = -x^3 + 4x^2 = x^2(x - 4)(x - 0) = x^2(x - 4)^1(x - 0)^2

2. Increasing the minimum wage has not traditionally caused massive unemployment though traditional economists have argued that it should. Why have changes to minimum wage not affected unemployment too much?
3. The US has one of the lowest federal minimum wages compared to other developed nations. Can you think of reasons why this might be?
4. The real minimum wage has fallen over time with the rise of inflation. This represents less purchasing power for minimum wage workers. Are you ok with that? Why or why not? How many people actually earn at or near minimum wage?
Despite traditional economic theory suggesting that an increase in the minimum wage should lead to unemployment, the actual impact on employment has been more nuanced. Empirical evidence suggests that moderate increases in the minimum wage have not led to massive job losses, but rather have resulted in small increases in labor costs that are offset by increased productivity and reduced employee turnover. Additionally, higher wages can increase consumer spending, leading to an increase in demand for goods and services, which can ultimately create more jobs.
There are several reasons why the federal minimum wage in the US is lower than in other developed countries. One reason is the political climate in the US, where there is often resistance to government intervention in the labor market. Additionally, many US states have their own minimum wage laws, which can be higher than the federal minimum wage. Finally, the US has a large low-skilled immigrant workforce, which can put downward pressure on wages.
I am not okay with the real minimum wage falling over time with the rise of inflation. Inflation erodes the purchasing power of workers, making it difficult for them to make ends meet. This can lead to increased financial hardship, which can have negative effects on individuals and families. Furthermore, the minimum wage was originally designed to ensure that workers earn a living wage, which is a basic necessity for a decent standard of living. As such, it is important that the minimum wage keep pace with inflation.
According to the Bureau of Labor Statistics, in 2021, about 1.9 million workers in the US earned at or below the federal minimum wage of $7.25 per hour. However, many more workers earn slightly above the minimum wage, and an increase in the minimum wage could potentially raise wages for those workers as well. Additionally, many states have higher minimum wage rates than the federal minimum wage, which means that the number of workers affected by changes to the minimum wage will vary depending on the state.
