g(x) = |14x + 3| is a function whose graph represents a horizontal stretch by a factor of 4 of the graph of f(x)=|x+3|.
How do we find the function that was used to create the graph?A graph contains information about which input corresponds to which output.An examination of this leads to the relationships that were used to create it.If a function's graph rises after a certain value of x, the function must have an increased output for inputs greater than that value of x.If we know that the function crosses the x axis at some point, we can use those as polynomial roots for some functions.So, we must write a function g whose graph represents a horizontal stretch of f(x)=|x+3| by a factor of 4.
f(x) = |x+3|Now perform horizontal stretch 4:
g(x) = |¼x + 3|Therefore, g(x) = |14x + 3| is a function whose graph represents a horizontal stretch by a factor of 4 of the graph of f(x)=|x+3|.

A stop sign in the shape of a regular octagon is inscribed in a circle. Find following measure.
m < LSR
The shape of a stop sign is the shape of a regular octagon. Each interior angle of the regular octagonal, m < LSR = 135.
What is the area of a regular octagon inscribed in a circle?
A regular octagon's area is inscribed in a circle with a radius of one unit. Divide the octagon into eight congruent triangles. The area of one triangle and multiply it by 8 to get the area of the entire octagon.
Because of its eight connected vertices, an octagon has eight sides. As a result, when we assign circle = 1, it has only one side, which is a curve, whereas when we assign octagon = 8, it has eight sides, so we assign it the value 8.
The shape of a stop sign is the shape of a regular octagon.
Each exterior angle of the regular octagonal sign is 360/8 = 45.
So, each interior = 180 – 45 = 135.
m < LSR = 135.
Therefore, the interior angle of the regular octagonal, m < LSR = 135.

The population of China is about 1.4 x 109
people, while the population of South Korea is
approximately 50,000,000 people. How many
times greater is the population of China than
the population of South Korea?
The population of China is 28 times greater than that of South Korea, calculated using solving of basic linear equation.
As per the question statement, the population of China is about (1.4 × 10⁹) people, while that of South Korea is approximately 50,000,000 people.
We are required to calculate that, by how many times is the is the population of China greater than that of South Korea.
To solve this question, let us assume that, the population of China is "x" times greater than that of South Korea. Hence, we will form a linear equation of single variable (x) and solving for "x", we will obtain our desired answer.
Since the population of China is assumed to be "x" times greater than that of South Korea,
[tex](50000000*x)=1.4*10^{9}\\ or,5*10^{7}*x=1.4*10^{9}\\or,5x=\frac{1.4*10^{9}}{10^{7}} \\or, 5x=1.4*10^{2}\\ or,5x=1.4*100\\or,5x=140\\or,x=\frac{140}{5}\\ or,x=28[/tex]
That is, The population of China is 28 times greater than that of South Korea.

Traveling carnivals usually shut down for the winter months. Suppose a traveling carnival decided to instead remain open for business indefinitely in its last stop of the season. Assume its usual revenue projections hold($15,000 on the first nigh, and each night's revenue after the first night will be about 75% of the previous night revenue). To the nearest dollar, what is the maximum amount of revenue the carnival can expect in the town?
The maximum amount of revenue the carnival can expect in the town in the 5th night is; $4746.093.
How to solve Geometric Progression?A geometric progression is defined as a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
We are told that Revenue in the first night = $15000
Now revenue of new night is 75% of the previous night. Thus;
2nd night = 15000 × 75/100 = $11250
3rd night = $11250 × 75/100 = 8437.5
Therefore, the given geometric sequence is ;
15000, 11250, 8437.5 ...
First term; a = $15000
Common ratio (r) = 11250/15000 = 0.75
The formula for the nth term of a GP is given by ;
aₙ = arⁿ ⁻ ¹
Thus, revenue for the 5th night is;
a₅ = ar⁵⁻¹
a₅ = 15000(0.75)⁴
a₅ = 4746.093
We conclude that the revenue in the 5th night in two will be $4746.093.

Any method of repositioning a figure in which the relative positions of the figure's points and vertices remain unchanged and the relative distance between them stays the same.
What does the mathematical meaning of congruence mean?
If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent, or to be in the relation of congruence.
Rigid motion satisfies these requirements because it is rigid, which means that everything that moves remains unchanged except from the location of the overall figure.

Write the equation of the line through each point. Use slope-intercept form.
(-7,10) ; parallel to 2x - 3y = -3 .
The equation of the line in slope-intercept form passing through the point (-7 , 10) and parallel to 2x - 3y = -3 is y = (2/3)x + 44/3.
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The slope-intercept form of the equation of a line is given by the formula:
y = mx + b
where m is the slope of the line
b is the y- intercept
If the line is parallel to 2x - 3y = -3, then their slopes are equal. First, express the equation in slope-intercept form y = mx + b to get the slope, m.
2x - 3y = -3
-3y = -2x - 3
y = -2/-3 x - 3/-3
y = 2/3 x + 1
m = 2/3
Substitute the values of the slope and the point to solve for the y-intercept, b.
y = mx + b
10 = 2/3(-7) + b
b = 44/3

Answer: The number 8,000 represents the change in height necessary to dodge the storm.
The integer representing the altitude after passing the storm is 30,000
Use appropriate tools, draw a number line to represent the airplanes changed altitude = 34000
Step-by-step explanation:
In the picture that is attached, the diagram for this query is displayed.
We are informed that the aircraft's starting height was 30,000 feet.
A. What integer represents the airplane's change in altitude to avoid the storm.?
During the storm:
The plane flew at at altitude of 38,000 feet
We will deduct the end altitude from the starting altitude to obtain the change in altitude.
change of altitude = final altitude - initial altitude
change of altitude = 38,000 - 30,000
= 8,000 ft
Therefore, the integer representing the change of altitude to avoid the storm is 8,000
B. What integer represents the airplanes change in altitude immediately after passing the storm?

Answer:
remainder: 3/4
Step-by-step explanation:
You want to divide the polynomial (2x^4-9x^3-x^2+2) by (2x-1).
Polynomial long divisionThe attachment shows the division worked out.
Your work has a sign error in the second product: (-4x²)(2x-1) should be (-8x³+4x²).
Factor theoremThe factor theorem tells you that if division by (2x-1) gives a remainder of 0, then (2x-1) is a factor of the dividend polynomial. Alas, here, the remainder is not zero, so 2x-1 is not a factor.
Remainder theoremThe remainder theorem tells you that the remainder of p(x) divided by (x-a) is p(a). We can evaluate the polynomial for x=1/2, the value that makes the divisor zero:
f(1/2) = ((2(1/2) -9)(1/2) -1)(1/2)^2+2 = ((-8)(1/2) -1)(1/4) +2 =(-5)(1/4) +2 = 3/4
The remainder from division by (2x -1) is 3/4.

20. The difference between the compound interest and the simple interest on a certain
Sum at 9% per annum for 2 years is 324. Find the sum.
The sum is 40,000.
The difference between compound interest and simple interest is 324 on a certain sum at 9% for 2 years.
So,
Compound interest - Simple interest = 324
C.I - SI = 324
The formula for compound interest is given as:
C.I = P( 1 + r/100 )ⁿ - P
Where P is the principal amount, r is the rate and n is the time in years.
Therefore,
C.I = P( 1 + 9/100)² - P
C.I = P( 1 + 0.09)² - P
C.I = P(1.09)² - P
C.I = 1.1881P - P
C.I = 0.1881P
Now, the formula for simple interest is given as:
S.I = ( P × R × T / 100 )
Where P is the principal amount, R is the rate and T is time in years.
Therefore,
S.I = ( P × 9 × 2 / 100 )
S.I = 18P / 100
S.I = 0.18P
Now,
C.I - S.I = 324
0.1881P - 0.18P 324
0.0081P = 324
P = 324 / 0.0081
P = 324 × 10000 / 81
P = 4 × 10000
P = 40000
Hence, the principal amount is 40,000.
