You used three methods of analysis to find the acceleration of the cart on the track: a two-point difference from v(t), an average of a(t) that was itself calculated by a succession of first differences of the v(t) data, and a line fit to v(t). some criteria to help you consider which method is best are part a in which type of graph(s) is it easiest to see whether the acceleration was constant?


Answered by answersmine AT 22/10/2019 – 02:29 AM

The best way to find that you want is the line fit. When acceleration is constant the speed(v) changes smoothly every moment, so the v line must be straight. Differently, the accelaration changes.

A company is setting its direct materials and direct labor standards for its leading product. Direct material costs from the supplier are​ $7 per square​ foot, net of purchase discount.​ Freight-in amounts to​ $0.10 per square foot. Basic wages of the assembly line personnel are​ $19 per hour. Payroll taxes are approximately​ 25% of wages. How much is the direct labor cost standard per​ hour


The formula for calculating the direct labor standard is:

Direct labor standard = Basic wages + Payroll tax

or

Direct labor standard = Basic wages + 25% of Basic wages

 

Substituting the given values into the equation:

Direct labor standard = $19 + 0.25 * $19

Direct labor standard = $23.75

The data set shown below represents the number of times some families went out for dinner the previous week. 4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1 Create a dot plot to represent the data. What can you conclude about the dot plot of the data set? Check all that apply. The range of the number line should be 0 to 7 to represent the frequency. Four families said they ate out twice the previous week. One family said they ate out 5 times the previous week. The data set is symmetrical. The median best represents the data set.


Answer:

The correct options are:

  • Four families said they ate out twice the previous week.
  • One family said they ate out 5 times the previous week.
  • The median best represents the data set.

Step-by-step explanation:

We are given a data set as:

4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1

On arranging this data set in the frequency table we get:

Number of times they went for dinner    Number of families  

           0                                                          2

           1                                                           3

           2                                                          4

           3                                                           1

           4                                                           2

           5                                                           1

           6                                                            1

  • Hence, the range of the number line is between 0 to 6.
  • Also there are 4 dots above 2.

    Hence,  Four families said they ate out twice the previous week.

  • Also there is one dot above 5.

        Hence,  One family said they ate out 5 times the previous week.

  • The data set is not symmetrical since the median is 2 and the data points to the left and to the right do not have symmetry.

Hence, the data set is not symmetrical.

  • Also we know that the median of the data is the central tendency of the data and always best represents the data.

Hence, The median best represents the data set.

Given 3 non-collinear points, which of the following statements are not true? There is only 1 plane that contains all 3 points. They will be contained in the same line. Any of the 3 points can be the intersection of 2 planes. Any 2 of the points defines a line entirely within the plane.


Non-collinear points are points which do not form a
straight line. Three non-collinear points create a plane therefore they are
always coplanar. Therefore the statements which are not true are:

They will be contained in the same line. 


Any of the 3 points can be the intersection of 2 planes.

Identify both the x- and y-intercepts of the linear equation graphed on the coordinate plane above. Use the intercepts to write an equation of the line in point-slope form, slope-intercept form, and general form of a linear equation.Complete your work in the space provided or upload a file that can display math symbols if your work requires it. In your work, be sure to include the coordinates for both intercepts and the equations of the line in all three formats.


The x int (where the line crosses the x axis) is (-2,0)
the y int (where the line crosses the y axis) is (0,-2)

(-2,0)(0,-2)
slope = (-2 – 0) / (0 – (-2) = -2/2 = -1

y = mx + b
slope(m) = -1
use either of ur points (-2,0)…x = -2 and y = 0
sub and find b
0 = -1(-2) + b
0 = 2 + b
-2 = b

so ur equation in slope intercept form is : y = -x – 2

y = -x – 2
x + y = -2
x + y + 2 = 0 <== general form

there can be 2 answer for point slope form…
y – y1 = m(x – x1)
slope(m) = -1
(-2,0)…x1 = -2 and y1 = 0
sub
y – 0 = – (x – (-2)
y – 0 = -(x + 2) <=== point slope form

y – y1 = m(x – x1)
slope(m) = -1
(0,-2)…x1 = 0 and y1 = -2
sub
y – (-2) = – (x – 0)
y + 2 = – (x – 0) <== point slope form

The following graph shows the demand curve for a group of consumers in the U.S. market (blue line) for Blu-ray players. The market price of a Blu-ray player is shown by the black horizontal line at $150. Each rectangle you can place on the following graph corresponds to a particular buyer in this market: orange (square symbols) for Antonio, green (triangle symbols) for Caroline, purple (diamond symbols) for Dmitri, tan (dash symbols) for Frances, and blue (circle symbols) for Jake. Use the rectangles to shade the areas representing consumer surplus for each person who is willing and able to purchase a Blu-ray player at a market price of $150. (Note: If a person will not purchase a Blu-ray player at the market price, indicate this by leaving his or her rectangle in its original position on the palette.

On December 15, 1791, the Bill of Rights (the first ten amendments to the United States Constitution) were ratified by the states.

The Bill of Rights were added to the Constitution to address fears raised by the Anti-Federalists during the ratification of the Constitution that the Constitution did not provide sufficient protection against abuses of power by the federal government. 

James Madison, the Father of the Constitution, originally did not think a Bill of Rights was necessary. He thought the Constitution gave no power to the federal government that would allow for a violation of the rights of the people.

Madison later changed his position, persuaded mainly by Thomas Jefferson, and, with the help of others, drafted twenty amendments that were proposed to the first United States Congress in 1789.

Twelve of the proposed amendments were accepted by Congress and were then sent to the states for ratification. Only ten were ratified.

These ten amendments list our basic rights and place limits on the federal government. They include the freedoms of speech and religion, the right to bear arms, the right to be free from unreasonable searches and seizures, and an assurance that the powers not delegated to the federal government in the Constitution are reserved to the states and the people. Many of these provisions were based upon similar protections provided by state constitutions that limited the power of state and local government authorities.

Of the remaining amendments that were not ratified in 1791, one was later adopted in 1992 as the twenty-seventh amendment to the Constitution. That amendment prevents changes in the compensation for senators and representatives until after a subsequent election of representatives. The other proposed amendment has never been adopted.

The Bill of Rights illustrates that our Founders understood that for personal freedoms to be broad, the power of the federal government must be limited.

Our nation, however, has moved away from its founding principles, especially during recent decades. Our ever-growing federal government is intervening into more and more aspects of our lives, especially through bureaucratic regulations, and is reducing our personal freedoms in the process.

Government at all levels is doing more and more things that were once left to private individuals and groups, and the federal government is doing more and more things that were once the province of state and local governments, where greater accountability to the public is often possible.

One need only look at the HHS mandate—forcing employers to violate their religious beliefs, under pain of penalty, by paying for and providing abortion pill insurance coverage—to see the harm caused by an overreaching government.

The preservation of our liberties is a daily battle, something our Founders understood. The process of scaling back the size and role of government and returning limits to it is a long one. But, since the federal government is supposed to be our servant and not our master, no one should doubt the importance of this endeavor.

Which line from act 1 of the importance of being earnest is an epigram? A. “There is no good offering a large reward now that the thing is found.” B. “… you have no right whatsoever to read what is written inside.” C. “More than half of modern culture depends on what one shouldn’t read.” D. “Well, if you want to know, Cecily happens to be my aunt.”


“More than half of modern culture depends on what one shouldn’t read.”

An epigram is a clever or witty saying that expresses an idea. This line epitomizes how Wilde feels about the ideals of morality during his time period. A strict set of rules that most people don’t follow. This also fits with the title as Ernest turns out not to be very earnest. The other lines are simply statements from the characters.

You do not have a multiple choice for the answer, but an equation for a line that includes that point starts off by using y=M(X)+b. So the equation can be anything but an example is y=-2(X)+2. To prove this equation works substitute the x and y values. 6=-2(-2)+2 —->   6=4+2 —–>6=6
