Calcule o montante obtido, através da capitalização composta, pela aplicação de R$2.000,00 por um ano e meio a uma taxa de juros

mel-nik [20]

Answer:

R$2.122,42

Step-by-step explanation:

Assumindo que a capitalização ocorre semestralmente, a fórmula que descreve o valor futuro (F) de um investimento (P) após 'n' semestres a uma taxa de juros 'i' é:

$F=P*(1+i)^n$

Aplicando P= R$2.000,00, n= 3 semestres e i = 0.02:

$F=2000*(1+0.02)^3\\F=R\$2.122,42$

O montante obtido é R$2.122,42.

Answer: No

Step-by-step explanation: proportional means corresponding in size or amount to something. However, the number of her sit-ups isn't consistent, so it isn't proportional to the time she spends doing them.
