Cuál sería la respuesta a esto? La señora María obtuvo un préstamo de 5 millones otorgado por un banco, para devolver el préstam

Lubov Fominskaja [6]

Answer:

La señora María debe pagar 463.635 guaraníes por concepto de intereses,

Step-by-step explanation:

Se recomienda utilizar el modelo de interés compuesto puesto que la tasa de interés es constante y periódico, dado que se conoce el monto a pedir prestado, la tasa de interés y el número de anualidades, se obtiene el monto final. La cantidad de dinero a pagar es la diferencia entre ese resultado y el monto a ser prestado.

El modelo de interés compuesto es representado por la siguiente fórmula:

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

Donde:

$C_{o}$ - Cantidad de dinero a prestar, medida en guaraníes.

$r$ - Razón de interés interanual, adimensional.

$t$ - Anualidad, medida en años.

$C(t)$ - Cantidad de dinero asociada a la anualidad actual, medida en guaraníes.

Si sabemos que $C_{o} = 5.000.000$ , $r = 0.03$ y $t = 3$ , entonces la cantidad de dinero asociada al término del período de préstamo es:

$C(3) = 5.000.000\cdot (1+0.03)^{3}$

$C(3) = 5.463.635$

Finalmente, la cantidad de dinero a pagar por concepto de intereses es:

$\Delta C = 5.463.635-5.000.000$

$\Delta C = 463.635$

La señora María debe pagar 463.635 guaraníes por concepto de intereses,

Which of the following are valid (necessarily true) sentences? a. (∃x x = x) ⇒ (∀ y ∃z y = z). b. ∀ x P(x) ∨ ¬P(x). c. ∀ x Smart

Phantasy [73]

Answer:

b; ∀x P(x) ∨ ¬P(x)

Step-by-step explanation:

Suppose that we have a proposition p

Such that p can be true or false.

We can define the negation of p as:

¬p

Such that, if p is false, then ¬p is true

if p is true, then ¬p is false.

Also remember that a proposition like:

p ∨ q

is true when, at least one, p or q, is true.

Then if we write:

p ∨ ¬p

Always one of these will be true (and the other false)

Then the statement is true.

And if the statement depends on some variable, then we will have that:

p(x) ∨ ¬p(x)

is true for all the allowed values of x.

from this, we can conclude that the statement that is always true is:

b; ∀x P(x) ∨ ¬P(x)

Where here we have:

For all the values of x, P(x) ∨ ¬P(x)

There are approximately 3.2 x 10^7 mosquitoes near each backyard pool. How many total mosquitoes are thre in a city with 6.7 x 1

dexar [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

There are approximately $3.2 \times 10^7$ mosquitoes near each backyard pool.

The city has total number of pools $6.7 \times 10^{12}$ .

So the total mosquitoes will be : $3.2 \times10^7 \times6.7\times 10^{12}$

So the total mosquitoes will be : $21.44 \times 10^{19}$

So the total mosquitoes will be : $2.144 \times 10^{20}$ : Answer

Hope it will help :)

A particular style of sunglasses costs the retailer $70 $⁢70 per pair. At what price should the retailer mark them so he can sel

Alexxx [7]

After the 10% discount on marked price (P), the selling price is ...

... P×(100% -10%) = 0.90P

After a markup off 35% on cost, the value is

... $70×(100% +35%) = 1.35×$70 = $94.50

The retailer wants these two values to be equal:

... 0.90P = $94.50

... P = $94.50/0.90 = $105.00 . . . . . divide by the coefficient of P

The marked price should be $105.00.
