Question

É URGENTE!!! A RESPOSTA COM O CÁLCULO!!! construir a matriz a = [ aij ] 4x3 , tal que aij = i – j + 5

Answer 1

Explicação passo-a-passo:

$A=\left[\begin{array}{ccc}a_{11} &a_{12}&a_{13}\\a_{21} &a_{22}&a_{23}\\a_{31} &a_{32}&a_{33}\\a_{41} &a_{42}&a_{43}\end{array}\right]$

Temos que$a_{ij} =i-j+5$

$a_{11} =1-1+5=5\\a_{12} =1-2+5=4\\a_{13} =1-3+5=3\\a_{21} =2-1+5=6\\a_{22} =2-2+5=5\\a_{23} =2-3+5=4\\a_{31} =3-1+5=7\\a_{32} =3-2+5=6\\a_{33} =3-3+5=5\\a_{41} =4-1+5=8\\a_{42} =4-2+5=7\\a_{43} =4-3+5=6$

$A=\left[\begin{array}{ccc}5&4&3\\6&5&4\\7&6&5\\8&7&6\end{array}\right]$
