Question
![Suppose \( Q \) is the quadratic form below:
\[
Q = \mathbf{x}^T A \mathbf{x}, \quad A = \begin{pmatrix} 5 & 2 & 1 \\ 2 & 8 & 2 \\ 1 & 2 & 5 \end{pmatrix}
\]
The minimum value of \( Q \) subject to \( \mathbf{x}^T \mathbf{x} = 1 \) is \( Q = 4 \). An eigenvector of \( A \) associated with eigenvalue \( \lambda = 4 \) is
\[
\mathbf{v} = \begin{pmatrix} 0 \\ 1 \\ c \end{pmatrix}
\]
What is \( c \) equal to? \[ \boxed{-2} \]
An eigenvector associated with eigenvalue \( \lambda = 4 \) is \( \mathbf{v} = (0, 1, -2)^T \). The minimum value of \( Q \), subject to \( \mathbf{x}^T \mathbf{x} = 1 \), is obtained at \( \mathbf{x}_0 \), where:
\[
\mathbf{x}_0 = \begin{pmatrix} 0 \\ k_0 \\ k_1 \end{pmatrix}
\]
If \( \mathbf{v} \) is parallel to \( \mathbf{x}_0 \) and \( k_0 > 0 \), what must \( k_1 \) be equal to? (answer must contain at least 3 decimal places)
\[ \boxed{-2} \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8b609ed5-0879-4e23-8eee-4515e84ef2b9%2Fe73538ee-0266-4617-bedb-c1d817e31345%2Fi46gifj_processed.png&w=3840&q=75)
