Hello,

Please help me with my AP Calculus math class work. If possible, please show me the last few steps to

the problem so I can learn from it. Not necessary but it would help! Thanks!

Let f ( t ) be the piecewise linear function with domain ! = = = & shown in the graph below ( which is determined byconnecting the dots ) . Define a function A(x ) with domain D = * = 8 byA ( * ) == ( $ ( D ) ` .Notice that ALE) is the net area under the function f(t ) for D = = = X . If you click on the graph below , a full – size picture ofthe graph will open in another window .*- 1/4 – — I- 5^Graph of * = f(t)

As usual, I don’t understand the following questions: (Remake)

1.How are the coordinates of the

new point found if it is rotated 90° counterclockwise? How many degrees is that equivalent to if the rotation is clockwise? 

2.How are the coordinates of the new point found if it is rotated 180° counterclockwise? How many degrees is that equivalent to if the rotation is clockwise? 

3.How would you describe what a rotation is. 

4.A triangle has coordinates A (1, 5), B (-2, 1) and C (0, -4). What are the new coordinates if the triangle is dilated with a scale factor of 1/5? 

5.A line segment has endpoints P (3, 6) and Q (12, 18) and is dilated so that its new endpoints are P’ (2, 4) and Q’ (8, 12). What is the scale factor? If the length of PQ is 15, what is the length of P’Q’? 

6.A triangle has coordinates A (1, 5), B (-2, 1) and C (0, -4). What are the new coordinates if the triangle is rotated 90° clockwise around the origin? 

7.How are the coordinates of the new point found if it is rotated 270° counterclockwise? How many degrees is that equivalent to if the rotation is clockwise? 

8.How are the coordinates of the new point found if it is dilated with a scale factor of 3?  

9.How would you describe what exactly a dilation is (geometry)

Individual Introductory lab to be submitted under this item through Canvas..

This is your first lab to explore how to use SAS and you are free to explore. The SAS website is an excellent resource. Once you are all set and you practice how to access and work with SAS, you will be assigned a group project and a final  project using large data collected from real sources ( Government sites, WHO, Financial data, world Bank, Engineering firms..) to study a topic of interest to you.

Math Homework Help. For this assessment, you will identify a published research article either in the print literature or online in the Capella University Library. Your article must be based on empirical (data-based) res

For this assessment, you will identify a published research article either in the print literature or online in the Capella University Library. Your article must be based on empirical (data-based) research; qualitative or purely descriptive research is not appropriate. Select a journal article in your career specialization that reports a correlation, a t test, a one-way ANOVA, or some combination of these test statistics. The library guides listed in the Resources area can help you to locate appropriate articles.

The intent of this assessment is to:

  • Expose you to professional literature in your discipline.
  • Provide practice in the interpretation of statistical results contained in an empirical (data-based) journal article.
  • Provide practice in writing and thinking in a concise and economical manner that is typical of scientific discourse.

You will summarize the article in a maximum of 600 words using the DAA Template located in the Resources area under the Required Resources heading. Specific instructions for completing each section of the DAA Template are listed below.

You may use some of the author’s own words to summarize the article with proper citation, but avoid lengthy direct quotes (such as copying multiple sentences or paragraphs verbatim). You should not exceed the limit of 600 words. This is a situation where less is better.

Step 1: Write Section 1 of the DAA

  • Provide a brief summary of the journal article.
  • Include a definition of the specified variables (predictor, outcome) and corresponding scales of measurement (nominal, continuous).
  • Specify the sample size of the data set.
  • Discuss why the journal article is relevant to your career specialization.

Step 2: Write Section 2 of the DAA

  • Discuss the assumptions of the statistical test used in the journal article.     
    • If possible, identify information in the article about how these assumptions were tested.
    • If no information on assumptions is provided, consider this as a limitation of the reported study.

Step 3: Write Section 3 of the DAA

  • Specify the research question from the journal article.
  • Articulate the null hypothesis and alternative hypothesis.

Step 4: Write Section 4 of the DAA

  • Report the results of the statistical test using proper APA guidelines. This includes:     
    • The statistical notation (such as r, t, or F).
    • The degrees of freedom.
    • The statistical value of r, t, or F, and the p value.
  • Report the effect size and interpretation if one is provided.
  • Interpret the test statistic with regard to the null hypothesis.

Step 5: Write Section 5 of the DAA

  • Discuss the conclusions of the statistical test as it relates to the research question.
  • Conclude with an analysis of the strengths and limitations of the study reported in the journal article

I need help 

Triangle ABC has coordinates A (-4, 4), B (4, 8), and C (4, 0). 

a. Find

the coordinates of the vertices of triangle A’B’C after a dilation using a scale factor of 0.75. 

b. Find the coordinates of the vertices of triangle A’B’C after a dilation of triangle A’B’C using a scale factor of 4. 

c. Use the scale factors given in parts (a) and (b) to find the scale factor you could use to dilate triangle ABC to its final image in one step. Explain.

2) If a figure has at least one vertex in every quadrant, will its dilation have at least one vertex in every quadrant? Explain.

3) The length of one side of an original figure is 110 units. The length of the corresponding side of the image figure is 11 units. What is the scale factor of the dilation?

4) You have $45 to buy noisemakers and hats for a party you are hosting. Each noisemaker costs $1 and each hat costs $3.

142* (*use SPSS to create a histogram and a Q-Q Plot of the data. Write a paragraph (or brief description) describing the histogram and write a separate paragraph describing the Q-Q Plot. In general, for both graphs you should describe if the data appear to come from a normal and justify. Be careful, you need to justify how you visually look at the separate graphs and come to your conclusions. These graphs will look very different and yet both will answer the same question about whether the data appear to come from a normal or not.)

Supplemental Homework Problems:

Supplement-1

Several large observational studies suggested that women who take hormones such as estrogen after menopause have a lower risk of a heart attack than women who do not take hormones. Hormone replacement became popular. But in 2002, several careful experiments showed that hormone replacement does not reduce heart attacks. The National Institutes of Health, after reviewing the evidence, concluded that the observational studies were wrong. Taking hormones after menopause quickly fell out of favor.

a) Explain the difference between an observational study and an experiment to compare women who do and don’t take hormones after menopause.

b) Suggest some characteristics of women who choose to take hormones that might affect the rate of heart attacks. In an observational study, these characteristics are confounded with taking

Supplement-2

State whether each of the two boldfaced numbers is a parameter or a statistic.

A study of voting chose 663 registered voters at random shortly after an election. Of these, 72% said they had voted in the election. Election records show that only 56% of registered voters voted in the election.
