Consider a radiograph that was produced using 100 kVp, 5 mAs, a 60 in. SID, and no grid. If the resulting radiograph is overexposed, what technique changes will reduce the exposure by half?

A radiograph is acquired using 120 kVp, a 16:1 grid, 72 in. SID, 500 mA, and AEC. How could these settings be changed to increase the radiographic contrast?

Use the Nernst equation to calculate the cell potential for the following cell: Sc|Sc3+, 0.0010M||Sn2+, 1.0M|Sn Sc3++ 3e−⟶Sc   Eo= −2.09V Sn2++2e−⟶Sn    Eo=  −0.1375V To receive full credit (2 pts for answer and 2 pts for showing work), submit a picture of your work to the Final Exam Required Work & Partial Credit  assignment AFTER SUBMITTING COMPLETED FINAL

A 29-year-old man is evaluated in the emergency department following a high-speed motor vehicle collision. He sustained multiple fractures and suffered significant blood loss. Temperature is 38.7°C (101.7°F), heart rate is 110/min, blood pressure is 85/50 mmHg, respiratory rate is 24/min, and oxygen saturation is 90% on room air. He receives 2 units of O-negative packed red blood cells. Two hours after the transfusion, he develops dyspnea, hypoxemia, and a non-productive cough. On examination, he appears anxious, tachypneic, and is using accessory muscles of respiration. There are no rashes. The trachea is midline. There is no jugular vein distension. Pulmonary auscultation reveals bilateral rales. There is no lower extremity edema. The patient is intubated and mechanically ventilated. PaO2/FiO2 is equal to 230. Chest X-ray is shown below. Which of the following is the most likely diagnosis?

A 58-year-old man is undergoing a red blood cell transfusion. Thirty minutes into the transfusion, he suddenly develops dyspnea, cough, and chest tightness. Past medical history is significant for hypertension and type 2 diabetes mellitus. Temperature is 38.7°C (101.7°F), heart rate is 110/min, respiratory rate is 28/min, blood pressure is 90/50 mmHg, and oxygen saturation is 88% on room air. On physical examination, he appears anxious and tachypneic. There is no rash or urticaria. Auscultation of the lungs reveals bilateral rales without wheezing. There is no lower extremity edema. Which of the following is the best next step in management?  

When announcing the reciprocal tariffs, President Trump and his administration provided a uniform explanation that these tariffs would remain in place over the long term and were not simply a negotiating tactic to get countries to enter trade negotiations with the United States.

Now you are going to create a scenario analysis in your Echolab solution, so first copy your initial valuation to a new sheet and name it “Scenario”. You will create a table to model the following scenarios to the right of the model inputs: United States:  Sales Year 1 of $28 million, Variable Costs of 27.5%, initial Revenue Growth of 14%, and SG&A of $500,000, $550,000 and $600,000  Slovakia:  Sales year 1 of $25 million, Variable Costs of 25%, Initial Revenue Growth of 15%, and SG&A of $300,000, $325,000, and $350,000 France:  Sales year 1 of $32 million, Variable Costs of 30%, Initial Revenue Growth of 12%, and SG&A of $400,000, $450,000, and $500,000 Make sure to have a dropdown menu for your audience to choose the different scenarios.  You should use each of the following at least once each in your model:  match, index, offset, and lookup. Which scenario would you tell the company to choose?

EchoLab is world-renowned for its sonar and radar equipment.  Its R&D team has been working tirelessly to create a new form of sonar to detect natural gas leaks from up to 5 miles away.  The company has spent $5 million on this research and to trademark the name “Sonarific”.  It is now ready to begin manufacturing. The company is considering building a new facility to manufacture this equipment.  It will build the new facility on a piece of land it purchased 3 years ago for $15 million.  The company ordered an appraisal on this land that cost the company $10,000 that values the land today at $16.25 million. EN will build a plant for $150 million on this land.  The plant has a useful life of 39 years and will be fully depreciated using straight-line depreciation.  The project will last for 10 years.  At the end of the 10 years, the company’s land and plant is expected to have a combined market value of $105 million. EN estimates that the first year Revenue will be $30 million, and that revenue will grow at 12.5% in year 2 with growth declining 1% per year thereafter (12.5%, 11.5%, 10.5%, etc.).  The variable costs are expected to be 28% of Revenues.  The accounting department will allocate $350,000 in overhead to the project, but none of this is new cost to the company (administration and executive salaries). SG&A for this project is expected to be $500,000 up to $30 million in Revenues, $550,000 for Revenues up to $40 million, and $600,000 thereafter (do not just hardcode the amounts; they need to update as the model changes). The company anticipates purchasing $5,000,000 in raw materials that will be partially financed with $2,000,000 in Accounts Payable.  Thereafter, the company anticipates it will need to have a balance in NWC of 12.5% of the year’s sales at the beginning of each year. The company has a cost of capital of 12.0% and faces a tax rate of 25%. Calculate the Free Cash Flows, IRR, NPV and Payback for this project.  Make sure these all update with any changes to the model. What is the NPV of this project.
