Questão de porcentagem - variações percentuais
Ao entrar no período seco, o volume do reservatório de uma hidrelétrica é reduzido a 20% ao mês, em relação ao mês anterior.
b) Se no início do período seco o reservatório apresenta 50% de sua capacidade, quando chegará a 20% de sua capacidade? (Use log2=0,30\log 2 = 0,30)
Gabarito: Após 4 meses
Me digam, por que não posso fazer isso abaixo?
estou me sentindo assim: Isso simplesmente não é possível (youtube.com)

b) Se no início do período seco o reservatório apresenta 50% de sua capacidade, quando chegará a 20% de sua capacidade? (Use log2=0,30\log 2 = 0,30)
Gabarito: Após 4 meses
Me digam, por que não posso fazer isso abaixo?
estou me sentindo assim: Isso simplesmente não é possível (youtube.com)

Re: Questão de porcentagem - variações percentuais
Mostre o passo-a-passo completo da sua solução, para poder ser analisada.
Eis a solução correta:
V = Vo.(1 - i/100)t ---> 0,20 = 0,50.(1 - 20/100)t ---> 0,4 = 0,8t ---> Aplicando log:
log0,4 = log0,8t ---> log(4/10) = t.log(8/10) --> log4 - log 10 = t.(log8 - log10) --->
2.log2 - 1 = t .(3.log2 - 1) ---> 2.0,3 - 1 = t.(3.0,3 - 1) --> - 0,4 = t.(-0,1) ---> t = 4
