Se deposita 4000 soles a una tasa de interés del 0,8% quincenas .¿Que interes producirá en cinco quincenas?

katen-ka-za [31]

Answer:

Interes= 162,58

Step-by-step explanation:

Dada la siguiente información:

Se deposita 4000 soles a una tasa de interés del 0,8% quincenas

Primero, debemos calcular el valor final de la inversión:

VF= [VP*( 1 + i)^n]

VF= 4.000*(1,008^5)

VF= 4.162,58

Para calcular el interés ganado en 5 quincenas, debemos usar la siguiente formula:

Interes= 4.162,58 - 4.000

Interes= 162,58

Answer:

See Explanation

Step-by-step explanation:

The question has unclear information.

So, I'll answer from scratch

Given

ABC = Right angled triangle

DB bisects ABC

Required

Prove that CBD = 45

From the question, we have that:

ABC is right angled at B

So, when DB bisects ABC, it means that DB divides ABC into two equal angles.

i.e.

$CBD = ABD$

and

$CBD + ABD = 90$

Substitute CBD for ABD in $CBD + ABD = 90$

$CBD + CBD = 90$

$2CBD = 90$

Divide both sides by 2

$\frac{2CBD}{2} = \frac{90}{2}$

$CBD = \frac{90}{2}$

$CBD = 45$

Hence, it is proved that $CBD = 45$

Follow the above explanation and use it to answer your question properly

Use Euler's method to obtain a four-decimal approximation of the indicated value. First use h = 0.1 and then use h = 0.05.

Juliette [100K]

Answer:

see below for the tables

Step-by-step explanation:

The differential equation is separable, so the solution is ...

$\displaystyle\dfrac{dy}{dx}=2xy\\\\\int{\dfrac{dy}{y}}=\int{2x}\,dx\\\\\ln{y}=x^2+C\\\\\text{Considering the initial condition, $C=-1$}\\\\\boxed{y=e^{x^2-1}}$

The values for yn are y+y'·h = y+2xyh. We take the "absolute error" to be the (signed) difference between the calculated yn and the actual value y(x).

If f(x) = 2x−5, then what is the value of f(2) + f(5)

DochEvi [55]

First of all f(2)=2(2)-5=-1 and f(5)=2(5)-5=5
so
f(2)+f(3)=-1+5=4

Answer:

5√2
16

Step-by-step explanation:

Use the property of 45 degree right triangles

c = a√2, where c- hypotenuse, a = legs

Top diagram

x = 5√2

Bottom diagram

x = 8√2(√2) = 16
