The LU factors of a matrix \( A \) are \[ \left[\begin{array}{ll} 1 & 0 \\ 2 & 1 \end{array}\right] \text { and }\left[\begin{array}{ll} 1 & 1 \\ 0 & 3 \end{array}\right] \] Use the LU factors to find the solution \( \boldsymbol{x} \) of \( \boldsymbol{A x}=\boldsymbol{b} \) for \[ \boldsymbol{b}=\left[\begin{array}{c} 9 \\ 33 \end{array}\right] \] The components of \( \boldsymbol{x}=\left[\begin{array}{l}x_{1} \\ x_{2}\end{array}\right] \) are \[ x_{1}=\text { Number } \] \( \square \) \[ x_{2}=\text { Number } \] \( \square \)
the voltage source delivers 75 W. If Vs = 15v, find I and R

Using Parseval's theorem, show that $\int_{-\infty}^{+\infty} \frac{1}{(a^2 + s^2)(b^2 + s^2)} ds = \frac{\pi}{ab(a+b)}$, where $a, b > 0$ are constants. You may use the fact that $\mathcal{F}[f_a](s) = \sqrt{\frac{2}{\pi}} \frac{a}{s^2 + a^2}$, where $f_a(x) = e^{-a|x|}$ and $a > 0$ is a constant.
the points (0,3), (1,4), and (2,3). Finally, sketch the graph of the function. Texts: The square root of 25 is 5.
Which of the following statements is NOT correct? ? The accountant obtains information about wages subject to payroll taxes from the payroll register. ? Most commercial banks are authorized to accept the employee's tax deposits for federal income taxes withheld and the employer's and employees' shares of social security taxes. ? Payroll tax deposits can be made electronically or using a Federal Tax Deposit Coupon, Form 8109. ? The \"lookback period\", in regard to payroll taxes, is defined as the previous month.
3. Determine whether x^4 + 10x + 1 is irreducible in Q[x]. If it is reducible then factor it as a product of irreducibles.
c) Using the functions for parts a) and b), solve for their second derivatives, but instead, use $O(\Delta x^4)$ accurate schemes for all points. This will require you to derive your own difference formulas near the boundaries. Always use the nearest available points. (Hint: This will require you to derive 4 methods for first and second derivatives). Save your results on HW5_7.dat and HW5_8.dat
