solve for 0<x<360, the equation sin(x+30)=-1/2​

Answers

Answer 1

Answer:

Below the explanation and result.

Explanation:

1) divide in possible cases

sin(x+30)=1/2

2) isolate "x + 30" and simplify

sin(x+30)=1/2

sin (π-(x+30))=1/2

3) calculate and isolate π-x-30

x+30= arcsin (-1/2)

sin (π-x-30)=-1/2

4)add period and calculate

x+30= -(π/6)

π-x-30=arcsin(-1/2)

5) resolve the equation and add the period

x+30= -π/6 +2kπ, k∈Z

π - x - 30= -π/6

6) resolve the equation

x= -π/6 - 30 + 2kπ, k∈Z

π-x-30=π/6+2kπ,k∈Z

7) like -2kπ=2kπ, so k∈Z

x=-π/6-30+2kπ,k∈Z

x=7π/6-30-2kπ,k∈Z

8) Find the union

x=-π/6-30+2kπ,k∈Z

x=7π/6-30+2kπ,k∈Z

9) RESULT:

x=-30+7π/6+2kπ,k∈Z

x=-30+11π/6+2kπ,k∈Z

Which option spells out the number correctly?

cuarenta y cuatro diez mil cuarenta y seis
cuarenta y cuatro mil ciento cuarenta y seis
cuarenta y cuatro mil cuarenta y seis
cuarenta y cuatro mil cero cuarenta y seis

Answers

cuarenta y cuatro mil cuarenta y seis

Answer:

The correct answer is: cuarenta y cuatro mil cuarenta y seis.

Explanation:

40.000: cuarenta mil.

4.000: cuatro mil

Together: cuarenta y cuatro mil. the first word "thousand" is deleted so that only one remains.

Now we go to the second part:

40: cuarenta.

6: seis.

Together: cuarenta y seis. The corresponding unit number (three, four, five, six, etc.) is added to the corresponding ten (twenty, thirty, forty, etc.)

As the number of spectators has not reached the first hundred, a zero is set and the tens are still counted, until it reaches the first hundred. That is why the number is 40,046 and the "zero" is not counted when told.

Answers

Answer:

Apellido.

Explanation:

First and last names help us identify and differentiate ourselves from the rest. In the case of surnames, many consider it a legacy left by our parents and for which we are obliged to honor them, since it represents a whole family. However, there was a time when they did not exist and it was only enough to have a name.

 

In ancient times, human beings were organized in small villages, so they knew each other and it was not necessary to offer more than a name to refer to someone. In the Middle Ages, larger cities and towns with large populations began to form, so it became necessary to better differentiate people, at which time the surnames appear.

Initially, the surnames corresponded to the place of origin of the person, his trade or to distinctive physical characteristics. In the case of the nobles, they adopted the last name of their dynasty or could keep that of some conquered territory, as a way of showing domination.

El motivo de mi pedido, es que en días de sofocante calor, los alumnos deben permanecer con telas abrigadas y que no dejan respirar fácilmente la piel. Además, el uniforme es un poco costoso, dificultándose para la adquisición de personas con bajo poder adquisitivo y los días de intensa lluvia, es complicado que el mismo llegue a secarse para el horario de clase.

Desde ya, muchísimas gracias.

El verbo está en primera persona del plural porque el sujeto es "nosotros". En la tercera oración, el sujeto es "usted" (tú) y el verbo es "ven" (tú comes).

Explanation:

The near future is formed with the personal forms of the verb ir + the preposition followed by the infinitive of the main verb. It is a verbal periphrasis that allows us to express a statement with a sense of the future. This construction is often used in Spanish instead of the simple future in the spoken language to express a planned action or something that will happen promptly.
