1. Solve the following first-order differential equation: y' - 3y = e3t
2. Suppose a baseball with a mass of 0.15 kilograms is thrown vertically upward with an
initial velocity of 35 m/s. Assume gravity is -10 m/s^2 and air resistance is b = 0.03.
How high does the baseball go?
You can assume the initial height is 0 meters.
Use the formula: ma = mg - bv
[First, input the values given into the formula above. Second, DERIVE the equations for
the velocity, v(t) and the position, s(t). It is NOT enough to use the equations from
Nagle's book, thirdly, figure out how high the baseball goes!)
3. Solve the following second-order differential equation:
4y" – 4y' + 5y = 0, y(O)=1, y'(O)=-11/2
4. Consider the differential equation: y" + 2by' + y = 0 where b is a constant. Describe
how the solutions to the equation change as b varies. In other words, there are three
solutions depending on the value of the parameter b. Write these three possible
solutions.

SWK 547 FIU MDCRM Social Work Agency Proposal Business Plan
The business plan you will add to last weeks work will show skills of intervention, evaluation, policy recognition, business development, and theory application) from a community and organizational perspective. This assignment involves creating a Business Plan and explaining how the program will function and be monitored and evaluated throughout and into the Evaluation Plan. Full Program Proposal with all components are as followsIntro letter, Community and Culture; Population Assets and Needs; Host Agency and Program Proposal; Program Function and Management; Program Mission, Services and Community Benefit (including goals, objectives and projected outcome); Evaluation; Timeline; and Summary. The components are the subsections of the Program Proposal. The total document must be less than 15 pages; yet a minimum of 10 pages. You cannot explain all the aspects of community, the need within, the plan to resolve the need, how the plan is orchestrated, managed, conducted and evaluated in pages fewer than 10. A good explanation takes careful thought and time. Be prepared for a consuming project.

Your selected news article or website should provide enough information to allow you to fully answer each of the questions below.For your post, identify your selected news article or website using correct APA formatting followed by your fully developed answers to each of the following:Describe the role of statistics in the news article or report.What was the population of the study?What was the sample?Do you believe the statistical results are believable and meaningful?Use the guidelines mentioned in Chapter 5C to explain why the results are believable and meaningful (or why not).What sorts of statistics (e.g., graphical, non-graphical, hypotheses, correlation, averages, etc.) were used in the report?How was the data distributed?How are distribution and variation important in any statistical study?Was any margin of error mentioned in the report?If no margin of error was mentioned, then assume that it is 2%. Interpret the margin of error in terms of 95% confidence interval.The actual group discussion will function the same as any other discussion. You will only be able to participate and discuss with those peers assigned to your same group.Your initial post should be at least 250 words in length. It should show all the required math work and explain all the steps. Also include a simple reference for any used resource.
