Warren is an investor who started investing in the market a year ago. He invested $100,000 in XYZ stock, ABC stock for $300,000, and deposited $100,000 in a bank account. It has been a year and since then, the price of stock XYZ has appreciated by 10% and the return of stock ABC is 7%. The bank account has an annual interest rate of 4%. What is the return of his entire portfolio? Let's use two methods to calculate the portfolio return. Method 1: Using the definition of return. The portfolio ending value is $ . The return is % Please enter your answer on return as a percentage. Round your answer to two decimal places. For example, if your answer is that the portfolio return is 5.25%, please enter 5.25. Do not add the percentage symbol %. Method 2: Using the weighted-average method. The portfolio weights are , , Please remove all the trailing zeros. The return is %.

Let \{u_1(x) = 9, u_2(x) = -12x, u_3(x) = -8x^2\} be a basis for a subspace of $P_2$. Use the Gram-Schmidt process to find an orthogonal basis under the integration inner product $(f, g) = \int_0^1 f(x)g(x) dx$ on $C[0, 1]$. Orthogonal basis: \{v_1(x) = 9, v_2(x) = -12x + a, v_3(x) = -8x^2 + bx + c\} a = b = c =

In order for documentation to provide benefits to your company, you must know which form of documentation to use. Which of the following best defines documenting processes and systems? Documenting processes and systems captures the people who work there or the state of its operations and internal controls. Documenting processes and systems creates programs used for moving data into and out of the database. Documenting processes and systems creates documentation that captures both the movement of data within the system and how data is stored in its database. Documenting processes and systems can be documented with a narrative description or a more complex flowchart, which can be costly to build and maintain.
