The possible rotation that transforms the image obtained from the reflection of the square ABCD on the line x = -1, with two vertices of the square remaining invariant is as presented as follows;
A rotation of the image of ABCD 270° counterclockwise, about the point (-2, -1) What is a rotation transformation?A rotation transformation is a transformation in which the preimage coordinate points are turned (in a circular manner) about a point.
The vertices of the square ABCD are; A(1, 4), B(3, 4), C(3, 2), D(1, 2)
The coordinates of the square following the reflection across the line x = -1 are; A'(-3, 4), B'(-5, 4), C'(-5, 2), and D'(-3, 2)
The rotation transformation of the image such that two vertices of the square are invariant (such that they remain the same) can be found as follows;
The rotation of a vertices of the image about the point (-2, -1) indicates the relative points are;
A'(-1, 5), B'(-3, 5), C'(-3, 3), and D'(-1, 3)
The image following a rotation of 270° are;
A''(5, 1), B'(5, 3), C'(3, 3), and D'(3, 1)
The above points relative to the origin are;
A''(5 + (-2), 1 - 1) = (3, 0), B''(5 - 2, -1 + 3) = (3, 2), C';(3 - 2, 3 - 1) = (1, 2), and D''(3 - 2, 1 - 1) = (1, 0)
A''(3, 0), B''(3, 2), C''(3, 4), and D''(1, 4)
The points (1, 2), and (3, 2) are therefore, the same as the points in the preimage and are therefore, invariant

Round the decimal number to the nearest tenth: 285.429 can you show steps?
Answers
"To round the decimal number 285.429 to the nearest tenth, we need to look at the digit in the hundredths place, which is 2.
If the digit in the hundredths place is 5 or greater, we round up the digit in the tenths place. If it is less than 5, we leave the digit in the tenths place as it is.
In this case, the digit in the hundredths place is 2, which is less than 5. Therefore, we leave the digit in the tenths place as it is, which is 2.
So, rounding 285.429 to the nearest tenth gives us:
285.4

Question 1
Find the unpaid balance, new interest, and purchasing power on the credit card after the minimum monthly payment is made. The interest charge for unpaid balances is 18% per year.
Credit Card Balance = $5000
Credit Limit = $5000
Minimum Payment = $125.00
Answers
Assuming that there are no other transactions or fees on the credit card, here's how to calculate the unpaid balance, new interest, and purchasing power on the credit card after the minimum monthly payment is made:
1.) Unpaid Balance: The unpaid balance is the amount of the credit card balance that remains after making the minimum monthly payment. In this case, the minimum monthly payment is $125, so the unpaid balance would be:
$5000 - $125 = $4875
2.) Interest Charge: The interest charge for unpaid balances is 18% per year. To calculate the monthly interest rate, divide the annual rate by 12:
18% / 12 = 1.5%
3.) To calculate the interest charge for the month, multiply the unpaid balance by the monthly interest rate:
$4875 x 1.5% = $73.13
So the new interest charge for the month is $73.13.
4.) Purchasing Power: Purchasing power refers to the amount of credit that is available on the credit card after making the minimum monthly payment and accounting for any interest charges. To calculate the purchasing power, subtract the unpaid balance and interest charge from the credit limit:
$5000 - $4875 - $73.13 = $51.87
So the purchasing power on the credit card after the minimum monthly payment is made is $51.87.

Answers
Answer:

[tex]\textsf{Zeroes:}\quad -6, 2, 5, 8[/tex]

[tex]\textsf{Factors\;with\;multiplicity:}\quad (x + 6)^3(x - 2)(x - 5)(x - 8)[/tex]
[tex]\textsf{Equation\;of\;function:}\quad f(x)=\dfrac{1}{3456}(x+6)^3(x-2)(x-5)(x-8)[/tex]
Step-by-step explanation:
ZeroesThe zeroes are the x-values of the points where the function crosses the x-axis, so the x-values when f(x) = 0.
Therefore, the zeroes of the given function are:
x = -6x = 2x = 5x = 8[tex]\hrulefill[/tex]
FactorsAccording to the factor theorem, if f(x) is a polynomial, and f(a) = 0, then (x - a) is a factor of f(x). Therefore, the factors of the function are the x-values that satisfy f(x) = 0.
Therefore, the factors of the given function are:
(x + 6)(x - 2)(x - 5)(x - 8)[tex]\hrulefill[/tex]
MultiplicitiesThe multiplicity of a factor is the number of times the factor appears in the factored form of the equation of the polynomial.
If the behaviour of the x-intercept is like that of a line, i.e. the curve passes directly through the intercept, its multiplicity is one.
Therefore, the factors (x - 2), (x - 5) and (x - 8) have multiplicity one.
The behaviour of the x-intercept at x = -6 is like that of a cubic function (S-shape). There, this zero has multiplicity 3: (x + 6)³.
[tex]\hrulefill[/tex]
DegreeSo far we have found the zeros, factors and their multiplicities, so we can write a factored form of the function:
[tex]\implies f(x)=a(x+6)^3(x-2)(x-5)(x-8)[/tex]
The degree of the function is the highest exponent value of the variables in the polynomial. Therefore, to find the degree of the function, simply sum the exponents of the factors:
[tex]\implies \textsf{Degree}=3 + 1 + 1 + 1 = 6[/tex]
Therefore, the degree of the function is 6.
[tex]\hrulefill[/tex]
Leading CoefficientFrom inspection of the given graph, the y-intercept is (0, -5).
Therefore, to find the leading coefficient (value of a), substitute (0, -5) into the equation and solve for a:
[tex]\begin{aligned}\implies f(0)=a(0+6)^3(0-2)(0-5)(0-8)&=-5\\a(216)(-2)(-5)(-8)&=-5\\-17280a&=-5\\a&=\dfrac{1}{3456}\end{aligned}[/tex]
Therefore, the leading coefficient of the function is 1/3456.
[tex]\hrulefill[/tex]
Equation of the functionPutting everything together, the function in factored form is:
[tex]f(x)=\dfrac{1}{3456}(x+6)^3(x-2)(x-5)(x-8)[/tex]
In standard form:
[tex]f(x)=\dfrac{1}{3456}x^6+\dfrac{1}{1152}x^5-\dfrac{1}{36}x^4-\dfrac{37}{432}x^3+\dfrac{17}{24}x^2+\dfrac{13}{8}x-5[/tex]

Using square process method, we can get the values of x to be 12 and 6.
Define square process?The formula a (x + m)2 + n = a (x + m)2 + n is the simplest to remember while learning how to complete the square technique.
The following formulas can be used to compute m and n in this situation: m = b/2a and n = c - (b2/4a).
From the question,
x² - 18x + 72= 0
⇒ x² - 18x = -72
Complete the square by adding the half of the square of the coefficient of x to both sides of the expression as shown:
⇒ x² - 18x + (18/2) ² = -72 + (18/2) ²
⇒ x² - 18x + 9² = -72 + 81
⇒ (x-9) ² = 9
⇒ x-9 = ± 3
So, values of x are:
x = 3 + 9
= 12
x = -3 + 9
= 6
Therefore, the values of x are 12 and 6.

Answers
Answer:
80
Step-by-step explanation:
The variable "n" is not defined, but rather "k" is used in the summation. Assuming that "n" was meant to be "k", the expression should be:
s4 = ∑ k=1 to 4 of 2(3^(k-1))
To evaluate this expression, we need to substitute each value of k from 1 to 4 into the expression 2(3^(k-1)), and then sum up the results.
Starting with k = 1:
2(3^(1-1)) = 2(3^0) = 2(1) = 2
Moving on to k = 2:
2(3^(2-1)) = 2(3^1) = 2(3) = 6
Next, k = 3:
2(3^(3-1)) = 2(3^2) = 2(9) = 18
Finally, k = 4:
2(3^(4-1)) = 2(3^3) = 2(27) = 54
Now we add up these four results:
s4 = 2 + 6 + 18 + 54 = 80
Therefore, the value of s4 is 80.

Answers
Answer:
First question:
We can start by setting up the formula that relates the volume V, temperature T, and pressure P:
V = k * (T/P)
where k is a constant of proportionality. We can solve for k by plugging in the given values for V, T, and P:
70 = k * (420/18)
Simplifying the right side of the equation, we get:
70 = k * 23.3333
Dividing both sides by 23.3333, we get:
k = 3
Now we can use this value of k to find the temperature T when V is 60 cm and P is 7:
60 = 3 * (T/7)
Simplifying the equation, we get:
T/7 = 20
Multiplying both sides by 7, we get:
T = 140
Therefore, the temperature when V is 60 cm and P is 7 is 140 kelvin.
Second question: We can start by using the formula that relates the time (T), distance (D), and speed (S):
D = S * T
Since the distance between the two cities is constant, we can set the distances for the two cars to be equal:
35 * 9 = 21 * T
Simplifying the right side of the equation, we get:
315 = 21T
Dividing both sides by 21, we get:
T = 15
Therefore, the trip takes 15 hours for a car moving at 21 mph.

Krish used to take thirty minutes to walk to his office. Recently, he bought a new cycle. Now he takes only seven-tenths of the time he used to take to reach office. How many minutes does he save by cycling to the office?
Answers
Answer:
Krish saves 9 minutes by cycling to his office.
Step-by-step explanation:
Krish used to take 30 minutes to walk to his office. After he bought a new cycle, he takes only 7/10 of the time he used to take to reach the office. Let's call the new time he takes to reach the office "t" (in minutes).
We can set up a proportion to find the value of t:
30 / 1 = t / (7/10)
To solve for t, we can cross-multiply:
30 * 7/10 = t
21 = t
So, Krish now takes 21 minutes to reach his office by cycle.
To find how many minutes he saves by cycling, we can subtract the new time from the old time:
30 - 21 = 9
Krish saves 9 minutes by cycling to his office.

What is a fraction?A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
To solve for which type of book covers the most space, we need to first convert 25% from a percentage to a fraction.
What is a percentage?A percentage is a ratio, or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.
If percentages are fractions of 100, then 25% as a fraction would look like this:
25% = [tex]\frac{25}{100}[/tex]We can do the same to 0.3, although it isn't a percentage.
0.3 = 0.30 = [tex]\frac{30}{100}[/tex]Now, we need to convert the fractions ([tex]\frac{25}{100}[/tex], [tex]\frac{30}{100}[/tex], [tex]\frac{7}{20}[/tex]) to have a common denominator.
What is a common denominator?A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.
To make [tex]\frac{7}{20}[/tex] have a denominator of 100, we can multiply the 20 by 5 to get 100.
7 × 5 = 4520 × 5 = 100Now the fraction is [tex]\frac{35}{100}[/tex].

In a quadrilateral ABCD, AB is parallel to DC, and AD is parallel to BC. Find the perimeter of △COD if the diagonals of the quadrilateral intersect each other at point O and AC=40 in, BD=50 in, AB=25in.
Answers
Answer:
Step-by-step explanation:
In quadrilateral ABCD, we have:
AB is parallel to DC
AD is parallel to BC
AC = 40 in (given)
BD = 50 in (given)
AB = 25 in (given)
We can use the fact that opposite sides of a parallelogram are equal in length to find the length of CD:
CD = AB = 25 in
Next, we can use the fact that the diagonals of a quadrilateral bisect each other to find the length of AO and OC:
AO = BO = BD/2 = 50/2 = 25 in
OC = OD = AC/2 = 40/2 = 20 in
Now we can use the triangle inequality to find the perimeter of triangle COD:
CO + OD + CD > OC
CO + 20 + 25 > 20
CO + 45 > 20
CO > -25
CO + OC > CO
CO + 20 > 0
CO > -20
CO + CD > OD
CO + 25 > 20
CO > -5
Therefore, the possible range of values for CO is:
-20 < CO < -5
However, since lengths cannot be negative, we can take the absolute value of CO to get:
5 < CO < 20
So the perimeter of triangle COD is:
CO + OD + CD = CO + 20 + 25 = CO + 45
Substituting the possible range of values for CO, we get:
5 + 45 < CO + 45 < 20 + 45
50 < CO + 45 < 65
So the perimeter of triangle COD is between 50 in and 65 in.
Therefore, the perimeter of triangle COD is between 50 in and 65 in, but the exact value depends on the length of CO, which is between 5 in and 20 in.

To find the cost equation, we can use the two data points given:
(100, 1400) and (400, 4100)
We can use the point-slope form of a linear equation, where the slope is the change in cost over the change in quantity:
slope = (4100 - 1400) / (400 - 100) = 2700 / 300 = 9
Using the point-slope form with the first data point:
y - 1400 = 9(x - 100)
y - 1400 = 9x - 900
y = 9x + 500
So the cost equation is y = 9x + 500.
To find the cost to manufacture 150 shoes, we can plug in x = 150 into the cost equation:
y = 9(150) + 500 = 1850
So the cost to manufacture 150 shoes is $1850.
To find the revenue function, we multiply the number of shoes sold by the price per shoe:
Revenue = price x quantity = 19x
To determine the number of items needed to break even, we need to find the quantity where revenue equals cost. Let C(x) be the cost function and R(x) be the revenue function. The break-even point occurs when:
C(x) = R(x)
9x + 500 = 19x
500 = 10x
x = 50
So the company needs to sell 50 designer shoes to break even.
Step-by-step explanation:
Answer:
Cost equation: y = 9x + 500
It costs $1,850 to manufacture 150 shoes.
Revenue function: R(x) = 19x
The number of items that need to be sold to break even is 50.
Step-by-step explanation:
Definition of variables
x is the number of designer shoes manufactured.y is the cost (in dollars) to manufacture the designer shoes.If it costs $1,400 to manufacture 100 designer shoes:
x = 100 when y = 1400.If it costs $4,100 to manufacture 400 designer shoes:
x = 400 when y = 4100.Assuming the relationship between the number of shoes and the cost to manufacture them is linear, the slope of the equation of the line the models the relationship can be found by dividing the change in y-values by the change in x-values of the two data points:
[tex]\implies \sf Slope\;(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4100-1400}{400-100}=9[/tex]
Substitute the found slope and one of the points into the point-slope form of a linear equation to create an equation that gives the total cost to manufacture the shoes in terms of the number of shoes (x):
[tex]\implies \sf y-y_1=m(x-x_1)[/tex]
[tex]\implies \sf y-1400=9(x-100)[/tex]
[tex]\implies \sf y-1400=9x-900[/tex]
[tex]\implies \sf y=9x+500[/tex]
Therefore, the cost equation is y = 9x + 500.
To calculate the cost to manufacture 150 shoes, substitute x = 150 into the cost equation:
[tex]\begin{aligned}\implies \sf y&=\sf 9(150)+500\\&= \sf 1350+500\\&= \sf 1850\end{aligned}[/tex]
Therefore, it costs $1,850 to manufacture 150 shoes.
The revenue is the income a company generates before any expenses are subtracted. Therefore, the revenue function is simply the selling price of the item multiplied by the number of items sold.
Given the product sells for $19 per item, the revenue function is:
[tex]\implies \sf R(x)=19x[/tex]
The break even point is the point at which the total revenue equals the total cost, so there is neither profit nor loss.
To determine the number of items that should be sold to break even, equate the cost equation and the revenue function and solve for x.
[tex]\begin{aligned}\sf R(x)&=\sf y\\\implies \sf19x&=\sf 9x+500\\\sf 10x&=500\\\sf x&=50\end{aligned}[/tex]
Therefore, the number of items that need to be sold to break even is 50.

Philip and Laura want to build a pool in their backyard. The length and width of the pool can be represented by the equation f(x)=(x-3)(5x+2) feet. What is the area of Philip and Laura’s pool? You must show your work and include your units.
Answers
Answer:
5x^2 - 19x + 15
Step-by-step explanation:
We must multiply the pool's length and width to determine its area. We can factor the equation f(x)=(x-3)(5x+2) to determine the length and width:
f(x) = (x-3)(5x+2)
f(x) = 5x^2 - 13x - 6
One of the parameters is the pool's length (x-3), while the other is its breadth (5x+2). We multiply these two elements to determine the area:
Area is length times width (x-3)
(5x+2)
By extending this statement using FOIL (First, Outer, Inner, Last), we may make it simpler:
Area is equal to 5x^2 - 13x - 6x + 15
Area: 5x^2 - 19x + 15
The pool at Philip and Laura's home is therefore 5x^2 - 19x + 15 square feet in size. We are unable to establish the precise square footage of the pool because we were not given a specific figure for x.
Solve g−17≥17 . Graph the solution.

The inequality expression g - 17 ≥ 17 when solved has a solution of g ≥ 34
How to solve the given inequalityGiven the inequality expression
g - 17 ≥ 17
To solve the inequality g - 17 ≥ 17, we need to isolate the variable g on one side of the inequality.
We can do this by adding 17 to both sides of the inequality:
g - 17 + 17 ≥ 17 + 17
Simplifying, we get:
g ≥ 34
So the solution to the inequality is all values of g that are greater than or equal to 34.
We can graph this solution on a number line by placing a closed circle at 34 and shading to the right, to indicate that any value greater than or equal to 34 satisfies the inequality.

Answers
The correct option to determine the value of volume of solid figure is: B. 10 × 3 × 6 and 4 × 3 × 6.
Explain about the rectangular prisms?One of the three-dimensional shapes that can be created with six pairs with parallel lines is a rectangular prism. Three-dimensional shapes in this category include cubes and cuboids. Prisms come in a variety of classifications based on the base.
Volume of rectangular prism = length * width * height
rectangular prism A:
length = 10 in.
Width = 3 in.
height = 6 in.
rectangular prism B:
length = 4 in.
Width = 3 in.
height = 6 in.
Thus,
volume of the solid = volume of rectangular prism A + volume of rectangular prism A
volume of the solid = 10*3*6 + 4*3*6
Thus, the correct option to determine the value of volume of the solid figure is: B. 10 × 3 × 6 and 4 × 3 × 6.

Answers
Answer:
1 product
Step-by-step explanation:
Given the equation that shows how the time required to complete an online shopping transaction is related to the number of products being purchased as;
t = 24p + 27
t represents the time required to complete the transaction
p is the product purchased
If it takes 51 seconds to complete a transaction, to get the amount of product purchased, we will substitute t = 51 into the expression and find p as shown;
51 = 24p + 27
Substract 27 from both sides
51-27 = 24p + 27 - 27
24 = 24p
24p= 24
p = 24/24
p = 1
Hence only 1 product is being purchased

If sin 0 = -2/3which of the following are possible?
Answers
Is sin (θ) = - 2/ 3, the options that are possible include:
A) sec(θ) = -3/2 and tan(θ) = 2/√5C) cos(θ) = -(√5)/3 and tan(θ) = 2/√5How to find the possible expressions?Since sec(θ) is negative, cos(θ) is also negative (sec(θ) = 1/cos(θ)). This means θ is in the second or third quadrant, but since sin(θ) is negative, θ must be in the third quadrant. Now let's check if the given tan(θ) value is correct:
tan(θ) = sin(θ)/cos(θ)
Since we already know that cos(θ) is negative, we have cos(θ) = -(√5)/3.
Now calculate tan(θ):
tan(θ) = (-2/3) / (-(√5)/3) = 2/√5
The given values in option A are correct.
cos(θ) = -(√5)/3 and tan(θ) = 2/√5
These are the same as in option A. So, this option is also possible.
