Answer:

[tex]a_{n}[/tex] = 10n

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 10 and d = a₂ - a₁ = 20 - 10 = 10 , then

[tex]a_{n}[/tex] = 10 + 10(n - 1) = 10 + 10n - 10 = 10n

The sequence can be seen to be an arithmetic sequence and the common difference of the sequence is 10.

Arithmetic sequences are an essential concept in mathematics and have applications in various fields, including algebra, physics, computer science, and finance. They are widely used to model patterns and relationships in real-world situations.

Looking at the sequence we can see that the common difference d can be obtained as;

d = S2 - S1

= 20 - 10

= 10

d = S3 - S2

= 30 - 20

= 10

Answer:

Approximately 13.41

Step-by-step explanation:

First do square root of each, which is finding what number multiplies by its self to get the number.

For example: The square root of 80 is approximately 8.94, and the square root of 20 is approximately 4.47.

So: 8.94 + 4.47 = 13.41 (Add normally, but remember to put the decimal in the right place).

Answer:

is this the full question?

Answer:

Step-by-step explanation:

k= 100- 4n

what is n if k is 99 ​

-------

99 = 100 - 4n

4n = 100 - 99

4n = 1

n = 1/4 or 0.25

--------------check

99 = 100 - 4 × 1/4

99 = 100 - 1

99 = 99

the answer is good

Answer:

y= 6/7

Step-by-step explanation:

0.5y + 7 = 5( 0.2 + 1.5y )

Get rid of the brackets first

0.5y + 7 = 1 + 7.5y

Move the like terms

0.5y + 7 - 7.5y = 1

0.5y - 7.5y = 1 - 7

Collect the like terms

-7y = -6

Divide both sides by -7 to get y on its own

y= -6/-7

A negative number divided by a negative number gives a positive number so

y = 6/7

Answer:

y=6/7  or 0.857 aprox.(0.86)

Step-by-step explanation:

[tex]0.5y+7=5(0.2+1.5y)[/tex]

[tex]0.5y+7=1+7.5y[/tex]

[tex]7.5y-0.5y=7-1[/tex]

[tex]7y=6[/tex]

[tex]y=6/7= 0.857[/tex]

It's the last option "24 + 49i + 15i^2"

Step-by-step explanation:

To solve you must do FOIL, (First, Outer, Inner, Last). To do this, you must do:

8 × 3 = 24 , 8 × 5i = 40i , 3i × 3 = 9i , and

3i × 5i = 15i^2 .

Don't forget to combine like terms.

Altogether: 24 + 49i + 15i^2 .

Answer:

A) 7.5 seconds

Step-by-step explanation:

Height of the ground is zero

-16t^2 + 120t = 0

Divide both sides by 16

-t^2 + 7.5t = 0

Factor out t

t(-t + 7.5) = 0

From the zero product rule

t = {0, 7.5}

0 would be time of launch

7.5 is time back to the ground

Hint: Use the Angle Addition Theorem and the fact that a line is made up of two opposite rays. Given: m∠1 = 62° and lines t and l intersect

Step-by-step explanation:

Step-by-step explanation:

Given: m∠1 = 62° and lines t and l intersect

Prove: m∠4 = 62°

Proof:

Statement                                        Reason

m∠1 = 62°                                         Given

m∠1 , m∠2 are supplementary       t is a straight line hence linear pair.

m∠4 , m∠2 are supplementary       r is a straight line hence linear pair.

Angle 2=180-62 = 118                      Definition of supplementary angles

Angle 4 = 180-118 =62                     -do-

Angle 1 = Angle 4                            Equality property

Hence proved
