You buy a car for 1000 every year it loses 40% of its value
VladimirAG [237]

Answer:

\displaystyle V_n=V_o\left(0.60\right)^n

<em>The car is worth 360 after two years</em>

Step-by-step explanation:

<u>Model For Depretiation</u>

Assume the situation of something that has an initial value Vo and loses its value by a x% every year. The first year it will lose

\displaystyle \frac{xV_o}{100}

and it will have a new value of

\displaystyle V_1=V_o-x\frac{V_o}{100}=V_o\left(\frac{100-x}{100}\right)

Next year it will have a value of

\displaystyle V_2=V_o\left(\frac{100-x}{100}\right)^2

Since x=40%, we can deduct the general formula

\displaystyle V_n=V_o\left(0.60\right)^n

For n=2

\displaystyle V_2=1000\left(0.60\right)^2

V_2=360

Si 2/3 partes de un capital producen $3.300 de interés en 7 meses y 10 días al 24%anual ¿Cuál es el valor del mencionado capital
miv72 [106K]

Respuesta:

33750

Explicación paso a paso:

Dejar :

Capital total = x

Principal = Inversión = 2 / 3x

Interés, = 3300

Periodo = 7 meses, 10 días = (7 * 30 + 10) = 220 días = 220/360

Tasa, r = 24% = 0. 24

Recordar :

Interés = principal * tasa * período

3300 = 2 / 3x * 0,24 * (220/360)

3300 = 0.0977777x

x = 3300 / 0,0977777

x = 33750

Help me find the answer
Charra [1.4K]
Since 1*7=7, 1 4/7= (7+4)/7=11/7. When dividing fractions, we switch the numerator and denominator for the bottom number, so in this case we'd have 
(11/7)*(6/5)=66/35=around 1.89
