Write an equation fo nth term of the given arithmetic sequence 7,13,19,25,...
Leya [2.2K]

Answer:

The nth term for the given sequence can be written as:

a_n=6\,n+1

Step-by-step explanation:

Notice that this arithmetic sequence is created by adding to each term a common difference of 6 units:

7 + 6 = 13

13 + 6 = 19

19 + 6 = 25

Then, using the general expression for the nth term of an arithmetic sequence of first term "a_1"  and common difference "<em>d</em>" we can write the nth term as:

a_n=a_1+(n-1)\,d

which in this case translates as:

a_n=a_1+(n-1)\,d= 7\,+(n-1)\,6=7+6\,n-6=6\,n+1

Select the equation of the line that passes through the point (5, 7) and is perpendicular to the line x = 4.
tresset_1 [31]

Solution:

Equation of line perpendicular to , x=4 is

y +k=0

As, keep in mind , the equation of line perpendicular to , ax + by +c=0 is b x - a y +c=0

As, given the line perpendicular to, x =4, passes through the point (5,7).  

So, y+k =0, passes through (5,7).

→ 7 +k=0

→ k= -7

So, line perpendicular to x=4, which passes through the point (5,7) is →y-7=0 that is y=7.

Option (C) →y=7

CONVERGENT AND DIVERGENT SERIES PLEASE HELP
drek231 [11]

Answer:

F.

Step-by-step explanation:

We are given a series

We can see that numerators are same

and denominators are

49 , 64 , 81 , .....

so,

7^2 , 8^2 , 9^2

We can write nth term

a_n=(n+7)^2

so, we can write as

\sum _{n=0}^{\infty }\:\frac{1}{\left(n+7\right)^2}

We can use p-series test

\frac{1}{n^p}

we can compare

and we get

p=2>1

So, this series is convergent

this is FALSE

-98 = 7t<br> What does t equal
pentagon [3]

Answer:

t = -14

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

-98 = 7t

<u>Step 2: Solve for </u><em><u>t</u></em>

  1. Divide 7 on both sides:                    -14 = t
  2. Rewrite:                                             t = -14

<u>Step 3: Check</u>

<em>Plug in t into the original equation to verify it's a solution.</em>

  1. Substitute in <em>t</em>:                     -98 = 7(-14)
  2. Multiply:                               -98 = -98

Here we see that -98 is equal to -98.

∴ t = -14 is the solution to the equation.

Solve the inequality.
AVprozaik [17]

Answer:

The answer to your question is the letter B.

Step-by-step explanation:

Data

         16(\frac{1}{4}x - \frac{1}{2}) > 24 - 2x

Expand

         \frac{16}{4}x - \frac{16}{2} > 24 - 2x

Add 2x in both sides

         \frac{16}{4}x - \frac{16}{2} + 2x > 24 - 2x + 2x

Simplify

         \frac{16}{4}x - \frac{16}{2} + 2x > 24

Add 8 in both sides

         4x - 8 + 8 + 2x > 24 + 8

Simplify

          6x > 32

Divide both sides by 6

           6x/6 > 32/6

Simplify

            x > 16/3
