I A music theorist associafes the fundamental frequency of a pitch \( f \) with a real number defined by \( p=69+12 \log _{2}\left(\frac{f}{440}\right) \). Complete parts a and b below. a. Standard concert pitch for an \( A \) is 440 cycles per second. Find the associated value of \( p \). \( p=\square \) (Round to the nearest whole number as needed.)

3. Sea \( A=\left(\begin{array}{lll}3 & k & 0 \\ 0 & 0 & 0 \\ 0 & 1 & 1\end{array}\right) \in \mathbb{R}^{3 \times 3} \). (a) Hallar todos \( \operatorname{los} k \in \mathbb{R} \) para que \( A \) sea diagonalizable. (b) Hallar todos los \( k \in \mathbb{R} \) para que \( (1,-1,1) \) sea autovector de \( A \).
