Using the concept of rotational symmetry, the angle of rotation about the center that results in an image that matches the original figure is; Option A: 90
What is rotational symmetry?Rotational symmetry is defined as a process that requires the rotation of a given object about a reference point to produce its image which has the same characteristics. This tells us that its dimensions, measure of internal angles and size do not change except its orientation. The orientation depicts the way in which the object is positioned.
here, we have,
The sum of an angle formed at a point is 360 degrees.
Thus turning a given object about a point implies its rotation with respect to a measured angle.
Thus in the diagram given in the question, the pattern shown divides the angle at the centered point into four equal parts.
Thus;
Angle of rotation = 360/4 = 90 degrees

a. a polynomial that represents the area οf the picture including the frame [tex]\mathrm{A = (x + 2w) \times (x + 2w) = (x + 2w)^2}[/tex]
b. The area οf the picture including the frame when the width οf the frame is 2 inches is [tex](x + 4)\²[/tex]
Why is it referred to as a polynomial?The English wοrd "polynomial" is derived from the Greek words "poly" and "nominal," which together denote "many sentences". The number of terms a polynomial can have is unbοunded.
a. Let x be the width οf the picture. Then the length of the picture is alsο x. Let w be the width οf the frame. The total width of the picture including the frame is (x + 2w), and the tοtal length of the picture including the frame is (x + 2w). Therefοre, the area of the picture including the frame is:
[tex]\mathrm{A = (x + 2w) \times (x + 2w) = (x + 2w)^2}[/tex]
b. If the width οf the frame is 2 inches, then w = 2. Substituting w = 2 into the polynomial above gives:
[tex]\mathrm{A = (x + 2w) \times (x + 2(2)) = (x + 4)^2}[/tex]

Imagine the country is made up of 100 households. The federal government needs to collect $800,000 in income taxes to be able to function. The population consists of 6 groups: Group A: 20 households that earn $12,000 each Group B: 20 households that earn $29,000 each Group C: 20 households that earn $50,000 each Group D: 20 households that earn $79,000 each Group E: 15 households that earn $129,000 each Group F: 5 households that earn $295,000 each This scenario is roughly proportional to the actual United States population and tax needs. We are going to determine new income tax rates. The first proposal we’ll consider is a flat tax – one where every income group is taxed at the same percentage tax rate. 1) Determine the total income for the population (all 100 people together)
The total income for the 100 households in the country, where the federal government needs to collect $800,000 in income taxes, is $6,810,000.
How is the total income determined?The total number for the 100 households is computed using the mathematical operations of multiplication and addition.
Multiplication operation involves multiplying the number of households in each group by the income earned by the group.
Addition operation involves summing the groups' household total income.
The population of the imagined country = 100 households
The expected revenue in income taxes = $800,000
The number of groups in the population = 6
Group Number of Households Income Total Income
Group A 20 $12,000 $240,000 (20 x $12,000)
Group B 20 $29,000 $580,000 (20 x $29,000)
Group C 20 $50,000 $1,000,000 (20 x $50,000)
Group D 20 $79,000 $1,580,000 (20 x $79,000)
Group E 15 $129,000 $1,935,000 (15 x $129,000)
Group F 5 $295,000 $1,475,000 (5 x $295,000)
Total income = 100 $6,810,000
Thus, using mathematical operations, the total income for the 6 groups of 100 households in the country is $6,810,000.

What is w, m, and n? please show your work and/or explain
Answer:
w = 102
m = 78
n = 58
Step-by-step explanation:
∠m is an exterior angle of the triangle on the left
exterior angle = sum of alternate interior angles
m° = 36° + 42°
m = 78
m and w are supplementary angles
m + w = 180
78 + w = 180
w = 180 - 78
w = 102
w is an exterior angle of the triangle on the right
w = n + 44
102 = n + 44
102-44 = n
n = 58

To pay for an 18,800 motorcycle, Salma made a down payment of 3500 and took out a loan for the rest. On the loan, she paid monthly payments of for 5 years.
Salma borrowed $15,300 and paid $295.24 per month for 5 years to pay off the loan.
What is loan?
In a loan, a certain quantity of money is given to another person in exchange for the value or main amount being repaid at a later date. In many circumstances, the lender increases the principal value by adding interest or finance charges, which the borrower must pay in addition to the principal sum.
To find out how much Salma borrowed, we can subtract her down payment from the cost of the motorcycle -
Loan amount = Cost of motorcycle - Down payment
Loan amount = 18,800 - 3,500
Loan amount = 15,300
Salma paid monthly payments for 5 years, which is equivalent to 60 months.
To calculate the monthly payments, we need to use the loan amount, the interest rate, and the loan term.
Let's assume the interest rate is 6%, which is a common rate for motorcycle loans.
We can use a loan calculator to find out the monthly payments -
Loan amount = 15,300
Interest rate = 6%
Loan term = 60 months
Using a loan calculator, we get a monthly payment of $295.24.
Therefore, Salma borrowed $15,300 and paid $295.24 per month.

Graph the function f(x)=1/2(2)^x on the coordinate plane.
The graph of [tex]f(x)=\frac{1}{2}(2^{x} )[/tex] on the coordinate plane is shown below.
Define a graph?A graph is a visual representation of a set of objects, typically represented as points or nodes, and the relationships between them, typically represented as lines or edges.
To graph the function [tex]f(x)=\frac{1}{2}(2^{x} )[/tex] on the coordinate plane, we can follow these steps:
Choose a range of x-values to plot. For this function, we can choose a range of x-values from -3 to 3.Calculate the corresponding y-values for each x-value. To do this, we can substitute each x-value into the equation [tex]f(x)=\frac{1}{2}(2^{x} )[/tex] and simplify. If x = 0, we get [tex]f(0)=\frac{1}{2}(2^{0} )[/tex] = 1/2. Similarly, If x = 1, we get [tex]f(1)=\frac{1}{2}(2^{1} )[/tex] = 1, and when x = -1, we have [tex]f(-1)=\frac{1}{2}(2^{-1} )[/tex] = 1/4.Plot the points (x, y) for each x-value and its corresponding y-value. For example, the point (0, 1/2) corresponds to the x-value 0 and y-value 1/2.Connect the points with a smooth curve to form the graph of the function.
The graph of [tex]f(x)=\frac{1}{2}(2^{x} )[/tex] on the coordinate plane is shown below.
Note that the graph of the function is an exponential curve that passes through the point (0, 1/2) and approaches the x-axis as x approaches negative infinity. As x approaches positive infinity, the function increases without bound.

Calculate (a) the weight of each type of coffee in 800 g of X: (b) the weights of type P coffee and type R coffee in 800 g of Y: (c) the ratio of the three types of coffee in a third standard blend Z. formed by mixing equal weights of X and Y: (d) the weight of type P coffee in 800 g of Z.
If two types of coffee. P and Q. are blended in the ratio 3: 13 by weight to form a standard blend X. The weight of type P coffee in 800g of X is 3x = 150g, and the weight of type Q coffee is 13x = 650g.
How to find the weight of type P coffee?(a) Let the weight of P coffee in 3 parts of X be 3x, and the weight of Q coffee in 13 parts of X be 13x. Then, the total weight of X is 16x.
We know that the ratio of P to Q coffee in X is 3:13, so the total weight of P coffee in X is 3x, and the total weight of Q coffee in X is 13x. Therefore, the weight of each type of coffee in 800 g of X is:
P coffee = (3/16) * 800 g = 150 g
Q coffee = (13/16) * 800 g = 650 g
(b) Let the weight of P coffee in blend Y be x, the weight of Q coffee be 7x, and the weight of R coffee be 12x.
We know that the ratio of P to Q to R coffee in Y is 1:7:12, so the total weight of P coffee in Y is x, the total weight of Q coffee in Y is 7x, and the total weight of R coffee in Y is 12x. Therefore, the weights of type P coffee and type R coffee in 800 g of Y are:
P coffee = (1/20) * 800 g = 40 g
R coffee = (12/20) * 800 g = 480 g
(c) To form blend Z, we mix equal weights of X and Y. Therefore, the total weight of Z is 800 g + 800 g = 1600 g.
The weight of P coffee in Z is (150 g + 40 g)/2 = 95 g.
The weight of Q coffee in Z is (650 g + 7/20 * 800 g)/2 = 465 g.
The weight of R coffee in Z is (12/20 * 800 g + 480 g)/2 = 480 g.
Therefore, the ratio of P to Q to R coffee in blend Z is 95: 465: 480.
(d) The weight of P coffee in 800 g of Z is (19/324) * 800 g = 47 g.

What is a bar graph?
A bar graph, also called a bar chart, is a kind of data visualization that uses rectangular bars to represent data. Each bar's height or length corresponds to the value it stands for. Bar graphs are frequently used to compare and present various data sets or to demonstrate how data has changed over time.
The vertical axis (y-axis) in a conventional bar graph indicates the values or quantities being measured, while the horizontal axis (x-axis) represents the categories or variables being compared. Each bar in the graph represents a separate category or variable, and they are arranged along the x-axis. Each bar's height or length denotes the value or amount related to that category or variable.
Depending on the volume and complexity of the data being presented, bar graphs can be simple or complex. They can be applied to emphasize patterns or trends in the data, demonstrate changes over time, or compare data across several groups or categories.

Describe what [tex]P(x) = x^4 - x^3 - 11x^2 + 9x + 18[/tex]. the graph looks like and, in general, how to sketch the graph without using technology. Use complete sentences, and focus on the end behaviours of the graph and where the company will break even (where P(x) = 0)
Answer:
Step-by-step explanation:
To sketch the graph of the polynomial function P(x) = x^4 - x^3 - 11x^2 + 9x + 18 without using technology, we can follow the following steps:
1. Determine the end behaviors of the graph: As x approaches negative infinity, the dominant term of the polynomial is x^4, which is positive. As x approaches positive infinity, the dominant term of the polynomial is also x^4, which is positive. Therefore, the end behaviors of the graph are both upward, which means that the graph rises to positive infinity on both ends.
2. Find the x-intercepts: To find the x-intercepts, we need to solve the equation P(x) = 0. One way to do this is to use synthetic division or long division to factor the polynomial. However, since the degree of the polynomial is 4, it may be difficult to find the roots algebraically. Alternatively, we can use technology or a graphing calculator to find the approximate values of the x-intercepts. Using a graphing calculator, we find that the x-intercepts are approximately -2.23, -0.43, 1.19, and 3.47.
3. Find the y-intercept: To find the y-intercept, we can set x = 0 in the equation P(x) = x^4 - x^3 - 11x^2 + 9x + 18, which gives P(0) = 18. Therefore, the y-intercept is (0, 18).
4. Determine the location of the minimum point: To find the location of the minimum point, we can use calculus and take the derivative of P(x) with respect to x. Setting the derivative equal to zero and solving for x, we find that x = -0.5 or x = 1. Therefore, the minimum point occurs at either (-0.5, P(-0.5)) or (1, P(1)). Using a graphing calculator, we find that the minimum value of P(x) is approximately -8.09, which occurs at x = -0.5.
Based on these steps, we can sketch the graph of P(x) as follows:
* The end behaviors of the graph are both upward.
* The x-intercepts are approximately -2.23, -0.43, 1.19, and 3.47.
* The y-intercept is (0, 18).
* The minimum point occurs at approximately (-0.5, -8.09).
* The graph is symmetric about the vertical line x = 0, since P(-x) = P(x) for all x.
5. To find where the company will break even, we need to find the values of x such that P(x) = 0. Using a graphing calculator or technology, we find that the company will break even at approximately x = -2.23, -0.43, 1.19, and 3.47. These correspond to the x-intercepts of the graph. Therefore, the company will break even at these values of x.

given that -3/2 is one of the root of the equation 2y^2+6y+p=0, find the value of p
Answer:
p = [tex]\frac{9}{2}[/tex]
Step-by-step explanation:
given y = - [tex]\frac{3}{2}[/tex] is a root of the equation , then this value makes the equation true.
substitute y = - [tex]\frac{3}{2}[/tex] into the equation and solve for p
2( - [tex]\frac{3}{2}[/tex] )² + 6(- [tex]\frac{3}{2}[/tex] ) + p = 0
2( [tex]\frac{9}{4}[/tex]) - 9 + p = 0
[tex]\frac{9}{2}[/tex] - [tex]\frac{18}{2}[/tex] + p = 0
- [tex]\frac{9}{2}[/tex] + p = 0 ( add [tex]\frac{9}{2}[/tex] to both sides )
p = [tex]\frac{9}{2}[/tex]
For part b, both answers I got come up as incorrect so I need help figuring out what the correct answers are. Im not sure why they’re wrong, this is a Elementary Statistics homework problem
For the new height requirements, this branch of the military requires women's heights to be at least 2.52 in and at most 6.96in.
How to get the z scores?If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
If we have
[tex]X \sim N(\mu, \sigma)[/tex]
(X is following normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] )
then it can be converted to standard normal distribution as
[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]
(Know the fact that in continuous distribution, probability of a single point is 0, so we can write
[tex]P(Z \leq z) = P(Z < z) )[/tex]
Also, know that if we look for Z = z in z tables, the p value we get is
[tex]P(Z \leq z) = \rm p \: value[/tex]
We are given that;
Mean= 63.8 in
Standard deviation= 2.3 in
Requirement of women height= 58in - 80in.
Now,
To find the minimum and maximum height requirements for this branch of the military, we need to use the standard normal distribution formula, which converts any normal distribution to a standard normal distribution with a mean of 0 and a standard deviation of 1.
We can find the z-scores for the minimum and maximum heights as follows:
For the minimum height requirement:
z = (58 - 63.8) / 2.3 = -2.52
For the maximum height requirement:
z = (80 - 63.8) / 2.3 = 6.96
Using a standard normal distribution table or calculator, we can find the corresponding probabilities for these z-scores:
For a z-score of -2.52, the probability is 0.0059 or 0.59%
For a z-score of 6.96, the probability is very close to 1, or 100%
Therefore, the new height requirements for this branch of the military are:
At least 58 inches, which corresponds to a z-score of -2.52
At most 80 inches, which corresponds to a z-score of 6.96
