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

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

Answer:
x = 3
Step-by-step explanation:
we are here given a figure in which we have to calculate the value of x . The given figure is made up of two right angled triangles , ∆RST and ∆QRT . So , firstly in ∆RST, we have ,
sinθ = p/h = RT/RS
sinθ = RT/2√3
and here θ = 60° , so that,
sin60° = RT/2√3
√3/2 = RT/2√3
RT = 2√3 * √3/2
RT = 3 . . . . . . . (1)
again in ∆RTQ , we have;
tanθ = p/b = RQ/RT
tanθ = x/3 ( from equation 1 )
and here , θ = 45° , so that ;
tan45° = x/3
1 = x/3
x = 3

Find two positive numbers whose difference is 23
23
and whose product is 3408
3408
The two positive numbers are 71 and 48
How to calculate for the two positive numbersWe 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.

What are the advantages and disadvantages of bases other than ten
The advantages and disadvantages of bases other than ten are shown below.
What is base ten?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.

Define congruent polygons.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.

Zoe rode her motorcycle down a straight freeway at 80kilometersperhour for a total of 4hours. There was a car behind her for one-half of that time. How far did Zoe ride while the car was behind her?
Write your answer as a whole number.
The distance that Zoe rode while the car was behind her was of:
160 kilometers.
How to obtain the distance?The relation between velocity, distance and time is that the velocity is the distance divided by time, hence the equation is presented as follows:
v = d/t.
The values of the parameters in this problem are given as follows:
Velocity of v = 80 km/h.Time of t = 4 h.(both of these measures are taken from the first sentence of the problem).

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
