Midterm Exam Hello everyone, Please respond to both questions correctly. Please remember to take time to go over your materials and respond accordingly. Your midterm will be worth 20 points and it will be 2 questions and it is open book: this means that you’ll be able to use your textbook, Ebook, calculators (except online calculators), notes, note cards, formula sheets, and scratch paper. Question 1. In 2008, as financial crisis began to unfold the U.S. the FDIC raised the limit on insured losses to bank depositors from $100,000 per account to $250,000 per account. How would this help stabilize the financial system? Question 2. If interest rates decline, which would you rather be holding, long-term bonds or short-term bonds? Why? Which type of bond has the greater interest-rate risk?

Texts: part 4 of 7 Answer part 4 of the question? y + 196y = 0. y = cos14x. y = sin14x What step should you take for each given function to verify that it is a solution to the given differential equation? A. Substitute the function into the differential equation B. Integrate the function and substitute into the differential equation C. Determine the first and second derivatives of the function and substitute into the differential equation D. Differentiate the function and substitute into the differential equation A. The indefinite integral of is ydx B. The first derivative is y' = 14cos14x and the second derivative is y'' = -196sin14x C. The first derivative is y' = -14sin14x and the second derivative is y'' = -196cos14x D. Substitute the appropriate expressions into the differential equation: 196cos14x + 196sin14x = 0 (Type the terms of your expression in the same order as they appear in the original expression) How can this result be used to verify that y = cos14x is a solution of y + 196y = 0? A. Differentiating the resulting equation with respect to x gives 0 = 0, so it is a solution to the differential equation. B. Solving this equation gives x = 0, which means y = cos14(0) = 1, so it is a solution to the differential equation.
