Find the common ratio of the geometric sequence.

Kay [80]

Answer:

The common ratio is $\frac{1}{x^4}$

Step-by-step explanation:

Geometric sequence:A geometric sequence is a sequence in which the ratio of any term to the preceding term of that term is always constant.

Common ratio: The ratio of any term to the preceding term of that term.

The $n^{th}$ term of a geometric sequence is represented by $a_n=ar^{n-1}$ .

The $1^{st}$ term of the sequence = a.

The sum of first n term is

$S_n=\frac{a(1-r^n)}{1-r}$

The common ratio = r.

Given geometric sequence,

$\frac{1}{x^{10}}$ , $\frac{1}{x^{14}}$ , $\frac{1}{x^{18}}$ , $\frac{1}{x^{22}}$ ........

The common ratio is

$=\frac{\textrm{second term}}{\textrm{first term}}$

$=\frac{\frac{1}{x^{14}}}{\frac{1}{x^{10}}}$

$=\frac{x^{10}}{x^{14}}$

$=\frac{1}{x^4}$

Solve tor r.<br> *a(5 – x) = bz - 8

Mars2501 [29]

Answer:

See explanation

Step-by-step explanation:

Assuming the given equation is

$a(5 - r) = bz - 8$

To solve for r, we first divide both sides by a.

$5 - r = \frac{ bz - 8}{a}$

We now subtract 5 from both sides:

$- r = \frac{ bz - 8}{a} - 5$

We now divide through by - 1 to get:

$r = 5 - \frac{ bz - 8}{a}$

$r = \frac{5a - bz + 8}{a} \: \: where \: a \ne0$

I need to help to ring the area of the base plz help me

Nataly [62]

Answer: 6

Step-by-step explanation:

the area of the base is the triangle base

the area of a triangle is bh/2

that looks like a perpendicular sign in the top left so b = 3 and h = 4

so area = 3*4/2 = 6
