If three consecutive term of an AP are x+4,2x+8 and 12. Find the value of x

Answers

Answer 1

Since the series is an Arithmetic progression, the difference between the consecutive terms is constant,

Therefore,

(2x+8) - (x+4) = 12 - (2x+8)

⇒ 2x + 8 - x - 4 = 12 - 2x - 8

⇒x + 4 = 4 - 2x

⇒ 3x = 0

x = 0

The value of x is 0,

So, the Arithmetic Progression is 4, 8, 12.......

What is an Arithmetic Progression?A numerical series in which the difference between the succeeding terms is constant is known as an arithmetic progression (AP). The number sequence 5, 7, 9, 11, 13, 15... is an example of an arithmetic progression with a common difference of 2.The term "finite arithmetic progression" or "arithmetic progression" refers to a finite segment of an arithmetic progression. An arithmetic series is the total of a finite arithmetic progression.There is a chance to come up with a formula for the nth term in an arithmetic progression. As an illustration, the number sequence 2, 6, 10, 14... is an example of an arithmetic progression (AP) since it follows a pattern in which each number is created by adding 4 to its preceding term. The nth word in this progression equals 4n-2.

Answer: 11.2

Step-by-step explanation: In order to find the length of n, you can use the given angle measure and base length as well as a trig ratio. Since 6.2 is adjacent to angle N, you can use tangent (opposite/ adjacent).

tan (61) = n/6.2

(multiply by 6.2 on both sides to isolate n)

• 6.2 • 6.2

tan (61) • 6.2 = n

11.185 = n

What is the circumference of a circle?

The radius squared times pi equals the area of a circle (A = r2). Find out how to apply this formula to determine a circle's area given its diameter.As a result, the circumference of a circle is pi times the diameter or 2 pi times the radius, which is how pi is typically defined as the ratio of a circle's circumference to its diameter. This provides a geometric reason that a circle's surface area is indeed equal to "pi r squared."

 A = πr²

differentiate both sides with respect to 't'

dA/dt = πr² dr/dt

Functions W and Z are both linear functions of x. Which statement comparing the functions is true? Select all that apply. A. The slope of Function W is less than the slope of Function Z. B. The slope of Function W is equal to the slope of Function Z. C. The slope of Function W is greater than the slope of Function Z. D. The y-intercept of Function W is less than the y-intercept of Function Z. E. The y-intercept of Function W is equal to the y-intercept of Function Z. F. The y-intercept of Function W is greater than the y-intercept of Function Z

Answers

The correct options are:

B. The slope of Function W is greater than the slope of Function Z.

F. The y-intercept of Function W is greater than the y-intercept of Function Z.

Let's find the slope (m) and y-intercept (b) of each function to see which one compares the two functions accurately.

Function W:

The slope of Function B, using two points on the line, (0, -1) and (2, 0):

m = ( y₂ - y₁ )/ (x₂ - x₁ )

m = [ 0 - (- 1 )]/( 2- 0 ) = 0.5

The y-intercept will be when x = 0. Therefore, from the graph, the y-intercept is b = -1.

For Function Z:

The slope of Function Z, using two pairs of values from the table of values for function Z, ( 0, - 2 ) and ( 2, - 1.5 ):

m = ( y₂ - y₁ )/ (x₂ - x₁ )

m = ( - 1.5 - ( -2 ) )/( 2 - 0 )

m = 0.5/2 = 0.25

The y-intercept is the value of y when x = 0.

From the table when x = 0, y = - 2. Therefore, the y-intercept is b = - 2.

Thus, the following statements that compare both functions are TRUE:

B. The slope of Function W is greater than the slope of Function Z.

This is TRUE because 0.5 is greater than 0.25.

F. The y-intercept of Function W is greater than the y-intercept of Function Z.

This is TRUE because -1 is greater than -2.

The sequence's 61st term is -972.

The sequence is -12 , -28 , -44.

Solution:

The following arithmetic sequence is: -12, -28, -44, ..

Find the common difference between the succeeding and preceding terms.

         c.d = first term - second term

-28 - (-12) = -28 + 12 = -16

-44 - (-28) = -44 + 28 = -16

As a result, the distinction between the terms remains constant.

This is a mathematical sequence.

The formula for the nth term of an arithmetic sequence is:

an = a1 + (n - 1 ) d

Where,

an is the sequence's nth term.

a1 is the sequence's first term.

The common difference between terms is denoted by d.

-12, -28, -44 are the numbers in the given sequence.

By changing the values in the formula,

a1 = -12

d = -16

Substituting values,

an = -12 + (n - 1 )(-16)

an = -12 - 16n + 16

an = 4 - 16n

Substitute n = 61 to find the 61st term.

a61 = 4 - 16 x 61

a61 = 4 - 976

a61 = -972

How to estimate total cost?

Given: While Verizon has a basic rate of only $10 per month but charges $0.10 for long-distance calls, T-Mobile has a base fee of $15 per month plus $0.05 for each minute you are on the phone.

We have to estimate how long would you need to call for them to charge the same amount.

Let the equation be 15 + 0.05 x = 0.10 x

⇒ 0.05 x - 0.10 x = -15

simplifying the above equation, we get

⇒ -0.05 x = -15

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length.

Perimeter of Triangle = side1 + base + side2

Let, the shortest side of the triangle = x

The other side length is = 2x

and, the length of third side is = x + 16

given perimeter = 156 feet

We know, perimeter of triangle = a + b +c

where, 'a' and 'c' stands for sides of triangle

and, b stands for base

hence, the expression will be according to formula,

x + 2x + x + 16 = 156

solve for 'x'

4x + 16 = 156

4x = 156 - 16

x = 140/4

x = 35

2x = 2 * 35 = 70
