Transforming the function f(x) = 2x by compression of a factor of 1/4 gives g(x) = 1/2x

Transformation of functions means that the curve representing the graph either "moves to left/right/up/down" or "it expands or compresses" or "it reflects". For example, the graph of the function f(x) = x2 + 3 is obtained by just moving the graph of g(x) = x2 by 3 units up. Function transformations are very helpful in graphing the functions just by moving/expanding/compressing/reflecting the curve without actually needing to graph it from scratch.

In the given function;

f(x)= 2x;

After a compression by a factor of 1/4, the function becomes

g(x) = 2x * 1/4 = 1/2x

The compressed function g(x) is 1/2x

Step-by-step explanation:

The two positive numbers are 71 and 48

We shall apply algebra in finding the unknown numbers as follows;

Let us represent the two numbers with the letters x and y

so that;

x - y = 23...(1)

xy = 3408...(2)

from equation (1),

x = 23 + y {adding y to both sides}

putting the value 23 + y for x in equation (2) we get;

(23 + y)y = 3408 {by expansion}

23y + y² = 3408

y² + 23y - 3408 = 0 {we rearrange to get a quadratic equation}

we factorize as follows;

y² + 48y - 71y - 3408 = 0

y(y + 48) - 71(y + 48) = 0

(y + 48)(y - 71) = 0

so by factorization; y = -48 or y = 71

the numbers are positive hence we take y = 71

putting the value 71 for y in equation (2) we get;

x71 = 3408 {divide through by 71}

x = 3408/71

x = 48

Thus; 71 - 48 = 23 and 71 × 48 = 3408, and we can say that the two positive numbers are 71 and 23.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given,

The scatter plot shows the daily oil production in the United States in the years since 1994.

The equation y=-168x+6,750 is the trend line for the data.

According to the equation of the trend line, we need to find how many thousands of barrels of oil will be produced daily in the United States 6 years from 1994

The advantages and disadvantages of bases other than ten are shown below.

The base-10 system is a way to give numbers a place value. As the position of the decimal point determines a number's mathematical value, it is often referred to as the place value number system or the decimal system.

In software systems, number systems with a base of 16 are frequently used. They have the fundamental benefit of being quickly convertible to binary systems.

The advantage of using number bases on 60 is that 60 may be divided by 2, 3, 4, and 6.  Its downside is that it is cumbersome.

Number systems based on 12 provide advantages comparable to those of number systems based on 60, but they give up the advantage of being divisible by 5 for the benefit of a less cumbersome system.

Therefore, base-10 number systems are not the best.

The polygons that are congruent are those whose vertices and sides line up perfectly. The 4 triangle congruence theorems that help in finding if the triangles are congruent or not are SSS, SAS, ASA, AAS, and RHS.

The polygons that are congruent are those whose vertices and sides line up perfectly. Congruent polygons are polygons having the same size and shape, even if they can be rotations, translations, or mirror reflections of one another. This is another way to conceive of the idea.

A triangle's congruence can be established using the triangle congruence theorem or triangle congruence criterion. The definition of congruent is "absolutely equivalent in shape and size regardless of rotation, flipping, or turning." Congruent figures are described in geometry as shapes that are superimposed on one another, such as triangles and quadrilaterals.

The following are the triangle congruence criteria that aid in demonstrating triangle congruence.

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangles be ΔRST and ΔQRT

Now , from the figure

∠S = 90° in the triangle ΔRST

And RS = 2/√3

∠T = 60° in the triangle ΔRST

Now ,

sin 60° = opposite / hypotenuse

           = RS / RT

           = ( 2/√3 ) / RT

We know , sin 60° = √3 / 2

Substituting the value of  sin 60° in the equation , we get

√3 / 2 = ( 2 / √3 ) / RT

Multiply by RT on both sides , we get

RT x ( √3 / 2  ) =  ( 2 / √3 )

Divide by ( √3 / 2  ) on both sides , we get

RT = ( 2 / √3 ) x ( 2 / √3 )

RT = 4 / 3

Therefore , the value of RT = 4/3

Now , from the figure

∠R = 90° in the triangle ΔQRT

and ∠T = 45° in the triangle ΔQRT

So ,

tan 45° = opposite / adjacent

We know tan 45° = 1

Substituting the value for tan 45° = 1 in the equation , we get

1 = opposite / adjacent

1 = x / RT

Multiply by RT on both sides , we get

x = RT

So , x = 4/3

Hence , The value of x is 4/3

What is inequality ?

Inequality of wealth in major cities Economic inequality comes in many forms, but two stand out above the rest: wealth inequality as measured by the distribution of wealth and income inequality as measured by the distribution of income.

The idea of inequality, which is the state of not being equal, especially in terms of status, rights, and opportunities1, is at the core of social justice theories. However, because it frequently has diverse meanings to different people, it is prone to misunderstanding in public discourse. However, some distinctions are universal.

Plan A: flat rate $8 per month and $3 per video viewed

Plan B: $5 per video viewed

The number of viewing videos is n

∵ The number of viewing videos is n

→ Plan A

∵ The cost per viewing is $3

∵ Cost per month is $8

∴ The cost = 8 + 3 n

→ Plan B

∵ The cost per viewing is $5

∴ The cost = 5 n

We need the cost of viewing n videos using  Plan A is less than the

cost of viewing n videos using Plan B

→ Cost Plan A < Cost Plan B

∵ Cost Plan A is 8 + 3 n

∵ Cost Plan B is 5 n

∴ 8 + 3 n < 5 n

* The inequality is 8 + 3 n < 5 n

∵ 8 + 3 n < 5 n

Subtract 3 n from both sides

∴ 8 < 2 n

Divide both sides by 2

∴ 4 < n

∴ n > 4

* Plane A is less expensive when n > 4

The inequality is 8 + 3 n < 5 n. Plane A is less expensive when n > 4

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

number of men given by y=3.9x+441 ​,

Now, Let us find the coordinates of the point of intersection of both lines by equating our both equations as:

3.9x+ 441 = 14.3x + 312

14.3x - 3.9x = 441 - 312
