(1 point) Consider the initial value problem my′′+cy′+ky=F(t), y(0)=0, y′(0)=0 modeling the motion of a spring-mass-dashpot system initially at rest and subjected to an applied force F(t), where the unit of force is the Newton (N). Assume that m=2 kilograms, c=8 kilograms per second, k=80 Newtons per meter, and F(t)=80cos(8t) Newtons. Solve the initial value problem. y(t)= Determine the long-term behavior of the system. Is limt→∞y(t)=0? If it is, enter zero. If not, enter a function that approximates y(t) for very large positive values of t. For very large positive values of t, y(t)≈

create a c++ proram to accept a positive number in the main program. Create and call the following functions 1.

1. OddorEven -to determine if the number is an odd or even number ( do not use $ or modul opeartor) and will return " even number " or " odd number ".

2. Factorial - to compute the factorial of N.

3. Power - to compute the power of N without using pow function.

display the result in the main function.

An environmentalist wants to find out the fraction of oil tankers that have spills each month.

Step 2 of 2:

Suppose a sample of 356 tankers is drawn. Of these ships, 246 did not have spills. Using the data, construct the 90% confidence interval for the population proportion of oil tankers that have spills each month. Round your answers to three decimal places.

• Question #2 Write a program that prints a nicely formatted table of the product of every pair of numbers in a given set of integer numbers. Your program reads two integer numbers x and y that represent the lower and upper bounds of the set, (?≤?x≤y), respectively. Then, for every pair of numbers in this set {?,?+1,?+2,…,?}{x,x+1,x+2,…,y}, your program should compute the product of the two numbers.

• Please note the following:
  1. Your program should read each input (lower bound and the upper bound) one at a time, and should make sure that each input is an integer. If not, it should prompt the user to re-enter a valid input.
  2. Once the two numbers are read, your program should validate that the lower bound is less than or equal to the upper bound. Otherwise, the input should be read again, starting from the lower bound.

Write 4-6 professional-level paragraphs on ANY movie of your choice that contains a leadership lesson (even FROZEN has a ton of leadership lessons - you just have to look for them.) Write up a summary of what leadership lessons you've learned. Be specific. I want to know what leadership styles you saw. Add what events showed you what kind of leader someone was. What situations were most impactful to you (as you as a developing leader yourself) as you watched the movie. What lessons will you takeaway into your own leadership and why?

Case 6: Project Resource Management
Several people working on the Healthy You Intranet Project are confused about their responsibilities for the testing portion of the project. Recall that the team members include you, a programmer/analyst and junior/assistant project manager; Ivan, a network specialist; Helen, a business analyst; and Bonnie, another programmer/analyst. Paul Sparks is the project manager, and he has been working closely with managers in other departments to make sure everyone knows what’s going on with the project.
The main tasks for testing include writing a test plan, unit testing and integration testing for each of the main system modules (registration, tracking, and incentives), system testing, and user acceptance testing.
In addition to the project team members, a team of user representatives is available to help with testing, and Paul has also hired an outside consulting firm ABC Digital to help as needed.
One of the issues Paul identified is the ability to work effectively with the user group during testing. According to MBTI classifications, Paul knows that several of his project team members are very introverted and strong thinking types, while several members of the user group are very extroverted and strong feeling types.

Prepare a responsibility assignment matrix (RAM) based on the information from this case.
3. Prepare a RACI chart (use the template) to help clarify roles and responsibilities for these testing tasks. Document key assumptions you make in preparing the chart.

Digital Access Inc. needs $323,640 in funds for a project. (Assume the loan term is one year.) a. With a compensating balance requirement of 7 percent, how much will the firm need to borrow? (Do not round intermediate calculations.) Amount to be borrowed $ b. Given your answer to part a and a stated interest rate of 17 percent on the total amount borrowed, what is the effective rate on the $323,640 actually being used? (Input your answer as a percent rounded to 2 decimal places.) Effective rate of interest %
