¿En cuánto se convierte un capital de C=$8,000 después de n=5 años a una tasa de interés compuesto del i=10% anual?
slava [35]

Evaluando una ecuación exponencial, veremos que luego de 5 años el capital se convierte en $12,884.08

<h3>¿En cuánto se convierte el capital?</h3>

Esta situación se podra modelar con la ecuación exponencial:

f(n) = $8,000*(1 + 10%/100%)ⁿ

Donde n es el número de años.

Podemos simplificar la ecuación para obtener:

f(n) = $8,000*(1.1)ⁿ

Ahora queremos ver el valor que toma esto cuando n = 5, asi obtenemos:

f(n) = $8,000*(1.1)⁵ = $12,884.08

Así que luego de 5 años, el capital se convierte en $12,884.08.

Will mark brainliest Which table of ordered pairs represents a proportional relationship?
Flauer [41]

Answer:

2y = x, which is a proportional relationship.

Step-by-step explanation:

See the table attached.

The table gives the ordered pair represents a proportional relationship.

Take at least two pairs of the value of x and y.

Let they are (6,3) and (10,5).

Now, the equation for the straight line passing through the two points is given by  

\frac{y - 5}{5 - 3} = \frac{x - 10}{10 - 6}

⇒ 2(y - 5) = x - 10

⇒ 2y - 10 = x - 10

⇒ 2y = x

Hence, we can write x ∝ y and the constant of proportionality is 2. (Answer)
