Question 2, 16.6.7 Part 1 of 2 HW Score: 0%, 0 of 15 points Points: 0 of 1 Save Use the given value of determinant A and the properties of determinants to evaluate determinant B. Determinant A $\begin{vmatrix} 8 & -8 & 7 \ -7 & 6 & 3 \ 6 & -1 & -2 \end{vmatrix} = -307$ Determinant B $\begin{vmatrix} 8 & 7 & -8 \ -7 & 3 & 6 \ 6 & -2 & -1 \end{vmatrix}$ What property (or properties) must be used in order to simplify the determinant? Select all that apply. A. If each element above or below the principal diagonal of a determinant is zero, then the product of the elements of the principal diagonal is the value of the determinant. B. If all elements of a column (or row) are multiplied by the same number $k$, the value of the determinant is multiplied by $k$. C. If two columns (or rows) of a determinant are identical, the value of the determinant is zero. D. If all elements of any column (or row) are multiplied by the same number $k$, and the resulting numbers are added to the corresponding elements of another column (or row), the value of the determinant is unchanged. E. If all corresponding rows and columns of a determinant are interchanged, the value of the determinant is unchanged. F. If two columns (or rows) of a determinant are interchanged, the value of the determinant is changed in sign.

Question 1 4 pts Given the network in Fig. P8.52, determine the magnitude of the $V_o$ phasor if $V_s = 14V$, $R1 = 3 \Omega$, and $R2 = 2 \Omega$. $V_s$ $R1$ $j2 \Omega$ $+ + $+ $-j1 \Omega$ $V_1$ $R2$ $V_o$ $- Note: The $V_o$ phasor will also have a phase angle, but this problem is only asking for the magnitude of the phasor, not the phase angle. • Provide your answer in Volts to the nearest tenth of a Volt • Do not include any units in your answer • Ex. If the magnitude is 5.12V, your submitted answer would be 5.1
