I need answer to number 4 please ASAP

Answer:

34 + 8n

Step-by-step explanation:

a₁ = 42

[tex]a_{n} = a_{n-1} + 8[/tex]

a₂ = a₁ + 8    = 42 + 8   = 50

a₃ = a₂ + 8   = 50 + 8 = 58

a₄ = a₃ + 8 =   58 + 8  = 66

Arithmetic sequence: 42, 50 , 58 , 66, ......

a₁ = 42 ; d = 8

[tex]a_{n}[/tex] = a₁ + d(n-1)

    = 42 + 8(n - 1)

    = 42 + 8n - 8

   = 34 + 8n

Answer:

[tex]a_{n}[/tex] = 8n + 34

Step-by-step explanation:

The explicit rule for an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given the recursive rule

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 8

where + 8 is the common difference d , then

[tex]a_{n}[/tex] = 42 + 8(n - 1) = 42 + 8n - 8 = 8n + 34

Explicit rule is

[tex]a_{n}[/tex] = 8n + 34

Answer:

g= -5

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    84-(4*(1-4*g))=0

 84 -  4 • (1 - 4g)  = 0

3.1     Pull out like factors :

  16g + 80  =   16 • (g + 5)

16 • (g + 5)  = 0

4.1      Solve :    16   =  0

This equation has no solution.

A a non-zero constant never equals zero.

4.2      Solve  :    g+5 = 0  

Subtract  5  from both sides of the equation :  

                     g = -5

Step-by-step explanation:

Step 1: Define equation

84 = 4(1 - 4g)

Step 2: Solve for g

Step 3: Check

Plug in g into the original equation to verify it's a solution.

Here we see that 84 does indeed equal 84.

∴ g = -5 is a solution of the equation.

The given inequality holds for the open interval (2.97,3.03)

It is given that

f(x)=6x+7

cL=25

c=3

ε=0.18

We have,

|f(x)−L| = |6x+7−25|

          = |6x−18|

          = |6(x−3)|

          = 6|x−3|

Now,

6|x−3| <0.18  then |x−3|<0.03 ----->−0.03<x-3<0.03---->2.97<x<3.03

Answer: x=180

Step-by-step explanation:

360/120=x/60

3=x/60

x=180

By the similarity of triangles the length of the side RS is 180 units.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know in similar triangles the ratio of their corresponding sides are equal.

Given, Are two triangles OPQ and ORS.

Therefore,

OP/PR = PQ/RS.

120/360 = 60/x.

120x = 21600.

12x = 2160.

x = 2160/12.

x = 180.

Step-by-step explanation:

The given linear equation can be simplified to:

15 = 40

Which means that the equation has no solutions.

Here we have the linear equation:

3*(2x + 5) - 6x = 40

And we want to see how many solutions does this equation has.

The solutions are the values of x such that the equation becomes true.

Then we can rewrite:

3*(2x + 5) - 6x = 40

Distributing the product we get:

3*2x + 3*5 -6x = 40

6x + 15 - 6x = 40

(6x - 6x) + 15 = 40

15 = 40

Notice that this equation does not depend of x, and it is false, (15 is not equal to 40)

So there are no value of x such that the equation is true, which means that the linear equation has no solutions.

The three main types of geography are physical, environmental and human geography. There are other sub-branches of geography such as political geography, historical geography and religious geography.

Physical geography deals with the study of Earth and its structure. The landforms, continents, oceans and tectonic movements are a part of physical geography. The formation of rocks, weathering, forces of erosion, winds, ocean currents and rivers are all studied as a part of physical geography. Environment geography deals specifically with the study of the interaction of plants and animals with Earth. Human geography focuses on how human societies flourish with the help of natural resources. It deals with the study of the evolution of cultures and religious beliefs. Economic, cultural and political geography are sub-branches of human geography.
