Answer

Question

Marque a alternativa que apresenta a matriz \(A=(a_{ij})_{2\times 4}\), sabendo que \(a_{ij}=3i+j\).

Answer

\(A=\left( \begin{array}{rrrr} 4 & 5 & 6 & 7 \\ 7 & 8 & 9 & 10 \end{array}\right)\)
\(A=\left( \begin{array}{rrrr} -4 & 2 & 6 & 7 \\ 7 & 3 & 9 & 1 \end{array}\right)\)
\(A=\left( \begin{array}{rrrr} -4 & 2 & 6 & 17 \\ 7 & 13 & -9 & 1 \end{array}\right)\)
\(A=\left( \begin{array}{rrrr} 0 & 2 & 6 & 7 \\ 1 & 3 & 5 & 1 \end{array}\right)\)

Question

Dada a matriz \(A=\left( \begin{array}{rrr} 2 & 0 & -5 \\ 4 & -3 & 1 \\ 2 & 1 & 5 \end{array}\right)\), Calcule \(a_{11} + a_{12} + a_{13}\)
