Responder:

4n-1

Explicación paso a paso:

Dada la secuencia

3, 7, 11, 15, 19, 23 ..

El enésimo término si la secuencia se expresa como;

Tn = una + (n-1) d

a es el primer término = 3

n es el número de términos

d es la diferencia común = 7-3 = 11-7

d = 4

Sustituir

Tn = 3+ (n-1) (4)

Tn = 3 + 4n-4

Tn = 4n-1

Por lo tanto, el enésimo término de la secuencia es 4n-1

Answer:

The solution of the given trigonometric equation

                   x = \frac{\pi }{6}

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given  

                cos( 3x - \frac{\pi }{3} )  = \frac{\sqrt{3} }{2}

                  cos( 3x - \frac{\pi }{3} )  = cos (\frac{\pi }{6} )

                      3x - \frac{\pi }{3}  =  \frac{\pi }{6}

                      3x - \frac{\pi }{3  } + \frac{\pi }{3}   =  \frac{\pi }{6} + \frac{\pi }{3}

                      3x = \frac{2\pi +\pi }{6} = \frac{3\pi }{6} = \frac{\pi }{2}

                     x = \frac{\pi }{6}

<u><em>Step(ii)</em></u>:-

The solution of the given trigonometric equation

                   x = \frac{\pi }{6}

<u><em>verification </em></u>:-

      cos( 3x - \frac{\pi }{3} )  = \frac{\sqrt{3} }{2}

put  x = \frac{\pi }{6}

    cos( 3(\frac{\pi }{6})  - \frac{\pi }{3} )  = \frac{\sqrt{3} }{2}

    cos (\frac{\pi }{6} ) = \frac{\sqrt{3} }{2} \\\\\frac{\sqrt{3} }{2} =  \frac{\sqrt{3} }{2}

Both are equal

∴The solution of the given trigonometric equation

                   x = \frac{\pi }{6}

Sarah and her dad visit Yo Yo yogurt again this time the scale says that Sarah has 14 oz of vanilla yogurt in her cup her father
Ainat [17]

Answer:

1\frac{5}{16} pounds

Step-by-step explanation:

We are given,

Amount of yogurt in Sarah's cup = 14 oz

Amount of yogurt in her father's cup = \frac{14}{2} = 7 oz

Thus, we get,

Total amount of yogurt bought by them = 14 + 7 = 21 oz

Since, 1 oz = 0.0625 pounds.

So, 21 pounds = 1.3125 pounds = 1\frac{5}{16} pounds

Hence, they bought 1\frac{5}{16} pounds on this visit.

NO LINKS!!<br><br>Which type of comic does not have vertices or foci? ​
creativ13 [48]

Answer:

  b) Circle

Step-by-step explanation:

<em>All</em> of the conic sections have vertices and foci. These features are not usually talked about for a circle, so perhaps "circle" is the expected answer.

__

A circle is a special case of ellipse with eccentricity 0. Its foci are coincident at its center, and its vertices are the ends of any pair of perpendicular diameters.
