Answers

Answer:

1) We know that e is an irrational number, so we usually can find it by computational methods.

[tex]e = \lim_{n \to \infty} (1 + \frac{1}{n})^n[/tex]

and we know that e accurate to 10 decimal points is:

e = 2.7182818285

2) Now we want to write the properties of the exponential and logarithmic functions.

We will write first the exponential property, and then the correspondent one for the logarithmic function.

(e^a)*(e^b) = e^(a + b)

The equivalent Ln property is:

Ln(a) + Ln(b) = Ln(a*b)

(e^a)/(e^b) = e^(a - b)

The eqivalent Ln property is:

Ln(a) - Ln(b) = Ln(a/b)

(e^a)^b = e^(a*b)

The equivalent Ln property is:

Ln(a^b) = b*Ln(a)

Kevin went to a store that offers a 20% discount. He bought a jacket and saved $11.20 after using the coupon. What is the original price of the jacket?

Answers

Answer: $56

Step-by-step explanation:

Let the original price of the jacket be x.

Since Kevin went to a store that offers a 20% discount and bought a jacket and saved $11.20 after using the coupon.

The original price of the jacket goes thus:

20% × x = $11.20

0.2 × x = 11.20

0.2x = 11.20

x = 11.20 / 0.2

x = 56

The original price of the jacket will then be $56

Step-by-step explanation:

By the right triangle geometric mean theorem, we have;

The altitude of a right triangle, 'h', which intersects with the hypotenuse side of the right triangle at a point such that it creates two segments, 'a' and 'b' on the hypotenuse side , then we have;

h = √(a·b)

Therefore, we have;

the angles given are corresponding angles meaning that they are congruent

so we set up an equation

step 1 subtract each side by 5

5-5 cancels out

-5-5=-10

now we have

23x-10=21x

step 2 subtract each side by 23x

21x-23x=-2x

now we have

-2x=-10

step 3 divide each side by 2

-10/-2=5

so we can conclude that

Un barril de petróleo equivale a 159 litros entonces si un pozo de petróleo produce 374 barriles por minuto. ¿Cuántos litros son? * 10 puntos A) 2.35 B) 4.80 C) 59 466 D) 128 345

Answers

Answer:

374 barriles equivalen a 59466 litros de petróleo.

Step-by-step explanation:

La regla de tres simple es una forma de resolver problemas de proporcionalidad entre tres valores conocidos y un valor desconocido, estableciendo una relación de proporcionalidad entre todos ellos. Es decir, lo que se pretende es encontrar el cuarto término de una proporción conociendo los otros tres. Recuerde que la proporcionalidad es una relación o razón constante entre diferentes magnitudes.

Si la relación entre las magnitudes es directa, es decir, cuando una magnitud aumenta, también lo hace la otra (o cuando una magnitud disminuye, también lo hace la otra), se debe aplicar la regla directa de tres. Para resolver una regla directa de tres, se debe aplicar:

a ⇒ b

c ⇒ x

donde a, b y c son valores conocidos, mientras x es el valor que se desea conocer. Entonces: [tex]x=\frac{c*b}{a}[/tex]

En este caso, la regla de tres se aplica de la siguiente manera: si 1 barril de petróleo equivale a 159 litros, 374 barriles a cuántos litros equivale?

1 barril ⇒ 159 litros

374 barriles ⇒ x litros

[tex]cantidad de litros =\frac{374 barriles*159 litros}{1 barril}[/tex]

cantidad de litros= 59466 litros

374 barriles equivalen a 59466 litros de petróleo.

B. {2, 3, 4, 5}
D. {0, 1, 3, 5}

Answers

Answer:

A. {0, 1, 3, 4}

Step-by-step explanation:

For a relation with elements (x, y)

The domain is the set of the x-values, that are the input values.

Here we have the relation:

{(4, -1), (3, 2), (0, -3), (1, 4)}

Here we can see that the inputs are:

4, 3, 0, and 1.

Then the domain is:

{4, 3, 0, 1}

Now let's write this in the correct order:

{0, 1, 3, 4}

The domain of the relation is: {0, 1, 3, 4}

Then the correct option is A.
