cuanto dinero se debe invertir a un interes de 14% compuesto continuamente para tener $500,000 en 35 años?
Alja [10]

Answer:

Se necesita depositar un capital inicial de $ 5096.83 pesos para lograr $ 500000 pesos a un interés compuesto de 14 % anual luego de 35 años.

Step-by-step explanation:

La cantidad ahorrada bajo interés compuesto está definida por la siguiente fórmula:

C(t) = C_{o}\cdot (1+r)^{t} (1)

Donde:

C_{o} - Capital inicial, medido en pesos.

C(t) - Capital actual, medido en pesos.

r - Tasa de interés, sin unidad.

t - Anualidad, medida en años.

Asumiendo que la tasa de interés compuesto es anual y si C(t) = 500000, r = 0.14 y t = 35, entonces el capital inicial es:

C_{o} = \frac{C(t)}{(1+r)^{t}}

C_{o} = \frac{500000}{(1+0.14)^{35}}

C_{o} = 5096.83

Se necesita depositar un capital inicial de $ 5096.83 pesos para lograr $ 500000 pesos a un interés compuesto de 14 % anual luego de 35 años.

The fastest race horse ran 1/4 mile in 1/3 of a minute. What was the horse's running speed?
bagirrra123 [75]

Answer:

3/4 miles per minute

Step-by-step explanation:

To get speed in miles per minute, just divide distance/time

1/4 mile / 1/3 minute = 3/4 miles per minute

If you want miles per hour, you'll have to convert minutes to hours.

3/4 miles/minute * 60 minutes/hour = 45 miles/hour

When y=-2, what kind of line does it have horizontal or vertical
Rashid [163]

Answer: Horizontal

Step-by-step explanation: The equation <em>y = -2</em> can be thought of as y = 0x - 2. So our line has a slope of 0 and a y-intercept of -2.

To graph it, we start with the y-intercept, down 2 units on the y-axis. Now, if the slope of a line is 0, then the line must be flat or horizontal.

So we just draw a horizontal line through the y-intercept of -2.

In fact, when the equation of any line reads y = a number, it's graph will always be a horizontal line. For example, y = 3, y = -10, y = -8 and so on.
