Answer:

Her daughters age: 1/2x

Step-by-step explanation:

Let's say Rani's present age is x. Her age is twice the age of her daughter.

So if Rani's age is 20, her daughters age would be 10, because Rani is twice the age of 10; so 10 times 2 would be 20.

1/2(20)=daughter's age

so if you substitute x into 20 because we don't actually know Rani's age, it would be 1/2(x)=daughter's age.

hope this helped :-) <3

A geometric sequence is defined by the equation an = (3)3 − n.

Delvig [45]

PART A

The geometric sequence is defined by the equation

$a_{n}=3^{3-n}$

To find the first three terms, we put n=1,2,3

When n=1,

$a_{1}=3^{3-1}$

$a_{1}=3^{2}$

$a_{1}=9$
When n=2,

$a_{2}=3^{3-2}$
$a_{2}=3^{1}$

$a_{2}=3$

When n=3

$a_{3}=3^{3-3}$

$a_{3}=3^{0}$
$a_{1}=1$
The first three terms are,

$9,3,1$

PART B

The common ratio can be found using any two consecutive terms.

The common ratio is given by,
$r= \frac{a_{2}}{a_{1}}$
$r = \frac{3}{9}$

$r = \frac{1}{3}$

PART C

To find
$a_{11}$

We substitute n=11 into the equation of the geometric sequence.

$a_{11} = {3}^{3 - 11}$

This implies that,

$a_{11} = {3}^{ - 8}$

$a_{11} = \frac{1}{ {3}^{8} }$

$a_{11}=\frac{1}{6561}$

PLSS HELPP WILL GIVE BRAINLIEST PLS ANSWER ALL 3

podryga [215]

Answer:

$\large \boxed{\sf non \ linear, \ non \ linear, \ linear, \ linear}$

Step-by-step explanation:

Write the equations in the form y = mx + b

If the equation contains exponents then it is non-linear, if not then it is linear.

2xy = 3

This graph forms a curve so it is non-linear

y = 1x³ + 5

This equation is non-linear because it contains an exponent

y = x/3

y = 1/3x + 0

This equation is linear ( no exponent(s) )

2y = 1/2x

y = 1/4x + 0

This equation is linear ( no exponent(s) )

The reciprocal of 7/2 is 2/7. What does that mean?

RoseWind [281]

Answer:2/7

Step-by-step explanation: A reciprocal is the "mirror image" of a fraction so the reciprocal is the fraction upside down.
