alguém sabe responder?​

Answer 1

Resposta:

Explicação passo-a-passo:

2)    $a_{n} = a_{1} . q^{n-1}$

       $a_{4} = a_{1} . q^{n-1}\\375 = a_{1} . 5^{4-1}\\375 = a_{1} . 5^{3}\\375 = a_{1} . 125\\ a_{1} =\frac{375}{125} \\\\ a_{1} = 3$

3)  J = C. i. t

   J =  1200 2 . 14

                  100

 J = 12 . 2  . 14

J =  24 . 14

J =  R$ 336,00       Alternativa A

4) C + C.  i . t   = M

  500 + 500 . i . 6  = 560

                     100

5 . i . 6 = 560 - 500

30 i = 60

     i = 60

          30

    i = 2%  Alternativa A

5)

$A+ B = \left[\begin{array}{ccc}0&5\\1&4\end{array}\right] + \left[\begin{array}{ccc}2&2\\0&1\end{array}\right] = \left[\begin{array}{ccc}2&7\\1&5\end{array}\right]$

Alternativa B
