State the domain for the following relation.{(4, -1), (3, 2), (0, -3), (1, 4)} *
A. {0, 1, 3, 4}
C. {0, 1, 2, 4}
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.

Find the angle of the least positive measure (in degrees, not equal to the given measure) that is coterminal with A.
A= -647°

Answers

9514 1404 393

Answer:

  73°

Step-by-step explanation:

A coterminal angle will be one that is this angle plus some multiple of 360°. We observe that the magnitude of the given value is between 360 and 720, so we can find the coterminal angle of interest by adding 720°.

  -647° +720° = 73°

The least positive measure angle coterminal with A is 73°.

Answers

Answer:17

Step-by-step explanation:

The time taken for her to reach the amount of $106,200 will be 17 years.

What is compound interest?

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

Given that:-

Alexa invested $54,000 in an account paying an interest rate of 4% compounded continuously.

The formula for calculating the compound interest continuously.

[tex]A \ = \ P e^ {rt}[/tex]

[tex]106200\ = \ 54000e^{0.04t}\\\\\\\dfrac{106200}{54000}=e^{0.04t}\\\\\\1.97\ = \ e^{0.04t}\\\\\\Ln(1.97)=Ln(e^{0.04t})[/tex]

Ln(1.97) = 0.04t

t  =   17 years.

Therefore the time taken for her to reach the amount of $106,200 will be 17 years.

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

Answer:

x = [tex]\frac{16}{3}[/tex]

Step-by-step explanation:

Since the triangles are similar then the corresponding sides are congruent.

EF and BC are corresponding sides , then

8x - 3 = 5x + 13 ( subtract 5x from both sides )

3x - 3 = 13 ( add 3 to both sides )

3x = 16 ( divide both sides by 3 )

x = [tex]\frac{16}{3}[/tex]

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.

E. Tram charges $14 per hour that she babysits.

D. Tram charges 7$ per hour that she babysits.

Answers

Answers:
A) Tran charges $140 when she babysits 10 hours

E) Tran charges $14 per hour that she babysits.

reasoning:

$70 divided by 5 hours to get how much she gets paid by the hour. 70 divided by 5 = $14; she charges $14/ hour. $14 times 10 hours = $140. these two statements are correct.

Answer:

A & E

Step-by-step explanation:

divide 70 by 5.

you get 14. meaning she charges $14 per hour

14 x 10 gives you 140.

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)
