What is the common ratio for the geometric sequence?<br><br> 18, 12, 8, 16/3,…

alex41 [277]

Answer:

2/3

Step-by-step explanation:

Given : A geometric sequence : 18, 12, 8, 16/3,…

Solution :

Each term is found by multiplying the previous term by a constant in a Geometric Sequence .

In a Geometric Sequence common ratio is denoted by r

$r = \frac{a_{n} }{a_{n-1} }$

for n = 2

$r = \frac{a_{2} }{a_{1} }$

⇒ $r = \frac{12 }{18 }$

⇒ $r = \frac{2 }{3 }$

for n = 3

$r = \frac{a_{3} }{a_{2} }$

⇒ $r = \frac{8 }{12 }$

⇒ $r = \frac{4 }{6 }$

⇒ $r = \frac{2}{3 }$

Thus the common ratio 'r' = 2/3

What is the domain and range of each relation?

LUCKY_DIMON [66]

Answer:

$\text{Domain of}R_1=\{-2,0,2,4\}$ and $\text{Range of}R_1=\{-3,-1,0\}$

$\text{Domain of}R_2=\{-3,-1,0,3\}$ and $\text{Range of}R_2=\{-1,0,1,2,3\}$

Step-by-step explanation:

Domain is the set of input values or x-values.

Range is the set of output values or y-values.

According to the relation mapping diagram, the relation is

$R_1=\{(-2,-3),(-2,-1),(0,0),(2,0),(4,-3)\}$

So,

$\text{Domain of}R_1=\{-2,0,2,4\}$

$\text{Range of}R_1=\{-3,-1,0\}$

In the graph 5 points are plotted. So, the relation is

$R_2=\{(-3,1),(-1,-1),(0,0),(3,2),(3,3)\}$

So,

$\text{Domain of}R_2=\{-3,-1,0,3\}$

$\text{Range of}R_2=\{-1,0,1,2,3\}$
