Determine the common ratio and find the next three terms of the geometric sequence 9,3sqrt3,3
Maru [420]

Answer:

Fourth term: a_4 = 9 * (\frac{\sqrt{3}}{3})^{(4 - 1)} = 9 * (\frac{\sqrt{3}}{3})^{3} = \sqrt{3}

Fifth term: a_5 = 9 * (\frac{\sqrt{3}}{3})^{(5 - 1)} = 9 * (\frac{\sqrt{3}}{3})^{4} = 1

Sixth term: a_6 = 9 * (\frac{\sqrt{3}}{3})^{(6 - 1)} = 9 * (\frac{\sqrt{3}}{3})^{5} =\frac{\sqrt{3}}{3}

Step-by-step explanation:

The geometric progression is:

9, 3 \sqrt{3}, 3...

The first term, a, is 9

To find the common ratio, r, all we have to do is divide a term by its preceding term.

Let us divide the second term by the first:

r = \frac{3\sqrt{3}}{9}\\ \\r = \frac{\sqrt{3}}{3}

That is the common ratio.

Geometric progression is given generally as:

a_n = ar^{(n - 1)}

where a = first term

r = common ratio

a_n = nth term

We need to find the 4th, 5th and 6th terms.

Fourth term: a_4 = 9 * (\frac{\sqrt{3}}{3})^{(4 - 1)} = 9 * (\frac{\sqrt{3}}{3})^{3} = \sqrt{3}

Fifth term: a_5 = 9 * (\frac{\sqrt{3}}{3})^{(5 - 1)} = 9 * (\frac{\sqrt{3}}{3})^{4} = 1

Sixth term: a_6 = 9 * (\frac{\sqrt{3}}{3})^{(6 - 1)} = 9 * (\frac{\sqrt{3}}{3})^{5} =\frac{\sqrt{3}}{3}

what is would be that answer when is Write an expression to describe the sequence below. Use n to represent the position of a te
aleksley [76]

Answer:

  an = n -27

Step-by-step explanation:

The general term (an) of an arithmetic sequence is given by the formula ...

  an = a1 + d(n -1)

where a1 is the first term and d is the common difference.

Your sequence has a first term of a1 = -26 and a common difference of d = 1. Putting these values into the formula gives ...

  an = -26 + 1(n -1)

This can be simplified to ...

  an = n - 27

Contesta si las siguientes proposiciones son falsas F o verdaderas V, colocando la letra que corresponda en el paréntesis. 1. La
AlexFokin [52]

Los valores de las proposiciones son:

  • 1) Falso
  • 2) Falso
  • 3) Verdadero
  • 4) Falso
  • 5) Verdadero
  • 6) Verdadero
  • 7) Falso
  • 8) Falso
  • 9) Falso
  • 10) Falso.

<h3>Analizemos las proposiciones.</h3>

Analizaremos cada proposicion para ver si esta falsa o verdadera.

1) "La recta está formada por un número finito de puntos."

Esto es falso, una recta esta formada por infinitos puntos. Si usaramos un numero finito de puntos, entonces tendriamos lugares donde la recta se corta.

2) " La magnitud de un ángulo depende de la longitud de sus lados."

Falso, el largo de los lados no tiene ninguna relación con la magnitud del angulo.

3) "Un rayo y una semirrecta son el mismo objeto geométrico."

Verdadero, ambos hacen referencia a una linea que tiene comienzo pero no tiene final.

4) "Un segmento tiene mayor longitud que un rayo"

Falso, un segmento tiene longitud finita y un rayo tiene longitud infinita.

5) "Por dos puntos solo se puede trazar una recta."

Verdadero, para cualquier par de puntos hay una sola recta que los conecta.

6) " La recta y el plano están formados por puntos."

Verdadero

7) "Por tres puntos cualesquiera, solo puede trazarse un plano."

Falso, segun cual par de puntos utilizemos para definir la recta, obtendremos un plano diferente.

8) "Por cuatro puntos cualesquiera solo puede trazarse un plano."

Falso, igual que antes.

9) "Si dos rectas se cruzan, forman 2 ángulos. "

Falso, si haces el dibujo, podras ver que se forman 4 angulos.

10) "La intersección de dos planos es un punto. ( )"

Falso, la intersección de dos planos es una linea.
