Below given are the steps to copy the original triangle using only two of its sides and the included angle.
What is triangle?It is a fundamental geometric shape in mathematics and has many applications in science, engineering, and everyday life. They can be classified based on the lengths of their sides and the measures of their angles.
Using point E as the center, draw a circle with a radius equal to the length of n×CA that was calculated in part B.
Using point E as the vertex, draw a ray DE in the direction of one of the sides of the angle to be copied (in this case, ∠BCA).
Create an angle at point E that is equal to the measure of ∠BCA. To do this, place the point of a compass at point E and adjust the compass to the length of segment CA. Then, draw an arc that intersects both sides of the ray DE. Without changing the width of the compass, place the compass at point C and draw an arc that intersects the previous arc. Draw a line connecting point E to the intersection of the two arcs to create an angle that is equal to ∠BCA.
Draw ray ED' from point E through the intersection of the two arcs.
Locate the intersection of ray ED' and the circle drawn in step 1. Label this point F.
Draw a polygon through points D, E, and F to complete the copied triangle, which is ΔDEF.
The resulting triangle ΔDEF will be a copy of the original triangle, with side EF corresponding to the included angle and sides DE and DF corresponding to the sides used to construct the copy.

He measures the angle of elevation from his hand to the kite to be 28 degrees. If the string from the kite to his hand is 105 feet long, how many feet is the kite above the ground? Round your answer to the nearest hundredth of a foot if necessary.
Please help!
Answer: The height of Nasim's kite above the ground is 51.79 feet
Step-by-step explanation
Let h represent the height from Nasim hand to the kite, hence:
sin(28) = h / 105
h = 49.29
Kite height above the ground = 2.5 + 49.29 = 51.79 feet
The height of Nasim's kite above the ground is 51.79 feet
Answer:
The height of Nasim kite above the ground is 51.79 feet
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height from Nasim hand to the kite, hence:

willka can cover 13.5 m^2 with 3L of paint
Willka would need 6 liters of paint to cover an area of 27 square meters according to the ratio.
What is ratio?A ratio is a comparison of two or more values or quantities. It is a way of expressing the relationship between two or more quantities in a mathematical form. A ratio is typically expressed in the form of "a:b" or "a to b", where a and b are two values being compared.
According to question:
To find the coverage per liter of paint, we can divide the total area covered by the amount of paint used.
In this case, we can divide 13.5 m² by 3 L:
Coverage per liter = 13.5 m² / 3 L = 4.5 m²/L
This means that with 1 liter of paint, Willka can cover an area of 4.5 square meters.
If we know the area to be painted, we can use this ratio to determine how much paint is needed.
For example, if we want to paint an area of 27 square meters, we can calculate:
Paint needed = area to be painted / coverage per liter = 27 m² / 4.5 m²/L = 6 L
So Willka would need 6 liters of paint to cover an area of 27 square meters.

Ryan wishes to purchase a new boat and can afford monthly payments of up to $500 per month. Finance is available, and the terms are that the loan lasts for 10 years and the annual interest rate is 13%. What is the maximum price for a boat that Ryan's budget can afford? Round your answer to the nearest hundred dollars.
Answer:
First, we need to calculate the total number of payments Ryan will make over 10 years, which is 10 years x 12 months/year = 120 months.
Next, we can use the formula for the present value of an annuity to calculate the maximum price of the boat:
PV = PMT x [1 - (1 + r/n)^(-nt)] / (r/n)
where PV is the present value, PMT is the monthly payment, r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years.
Plugging in the values we have:
PMT = $500
r = 0.13
n = 12 (since the loan is monthly)
t = 10
PV = $500 x [1 - (1 + 0.13/12)^(-12x10)] / (0.13/12)
PV = $44,484.72
Therefore, the maximum price for a boat that Ryan's budget can afford, rounded to the nearest hundred dollars, is $44,500.

Answer:
-1, -6, 13, 20 is an arithmetic sequence
d = 7
5, 12, 19, 26 is arithmetic sequence
d = 7
-3 - 9, -27, -81 is not an arithmetic sequence
Step-by-step explanation:
Common difference is the difference between successive terms and must be the same for all terms
-1, -6, 13, 20 is an arithmetic sequence with common difference:
6 - (-1) = 13 - 6 = 20 - 13 = 7
5, 12, 19, 26 is arithmetic sequence with common difference
12- 5 = 19 - 12 = 26 - 19 = 7
-3 - 9, -27, -81 is not an arithmetic sequence
The difference between successive terms is not the same
-9 - (-3) = -9 + 3= -6
but
-27 - (-9) = -27 + 9 = -18
In fact it is a geometric sequence where each term = x previous term
-9 = 3 x -3

The required graph is attached.
What is a graph?An organized representation of the data is all that the graph is. It facilitates our understanding of the facts. Data is the term used to describe the numerical information obtained through observation.
The modification looks like this.
Combining two transformations results in the transformation of
h(x) to -h(x) -4.
1. An X-axis-centered reflection. Every point (x, y) in h(x) is transformed into (x', y'), where x' = x and y' = -y. Hence, (x, y) (x, -y)
2. A 4-unit translation of each reflected point, where the x value remains constant, but the y value is translated downward to become y'-4 = -y -4
Every coordinate (x, y) in h(x) will be transformed to the following as a result of both transformations: (x, -y -4)
Given that the graph is made up of two straight lines that intersect at the origin, all we need to do is select any three points in h(x), determine their transformed coordinates, and then connect them using straight lines: h(x0 -h(X) - 4 (-2, 4) (-2, -4-4) =(-2, -8) (0, 0) (0, -0 - 4) =(0, -4) (4, 2) (4, (4, -6)

Let's choose two points on the original line:
Point 1: (0, -4)
Point 2: (1, -2)
Now we apply the transformation rule to each of these points:
Point 1 image: (-0, -(-4)) = (0, 4)
Point 2 image: (-1, -(-2)) = (1, 2)
The images of these two points lie on the line y = -2x + 4. The slope of this line is -2.

Tο determine the expected frequencies, we need tο assume that the null hypοthesis is true. Since there are fοur seasοns, each seasοn is expected tο have 1/4 οf the tοtal number οf resignatiοns. Therefοre, the expected frequency fοr each seasοn is 60/4 = 15.
Calculate the test statistic:
The test statistic fοr the chi-squared gοοdness οf fit test is calculated using the fοrmula:

Dirk and Steve both plan to run to a spot on the school board in their city. They must each collect a certain number of signatures to get their name on the ballot. So far, Dirk has 20 signatures, but Steve just started and doesn't have any yet. Kirk is collecting signatures at an average rate of 6 per hour, while Steve can get 10 signatures every hour. Assuming that their rate of collection stays the same, eventually the two will have collected the same number of signatures. How many hours will have gone by?
Answer: 2.5 hours
Step-by-step explanation:
Let's call the number of signatures that Steve needs to collect "x". We know that Dirk has 20 signatures, so he needs to collect "x - 20" more signatures to have the same number as Steve.
We can set up an equation to represent this:
6h + 20 = 10h + x - 20
Simplifying this equation, we get:
x = 4h + 40
So, Steve needs to collect 4 signatures more per hour than Dirk to eventually collect the same number of signatures. We can solve for "h", the number of hours it will take for them to have the same number of signatures:
6h + 20 = 10h + (4h + 40)
6h + 20 = 14h + 40
8h = 20
h = 2.5
So, it will take 2.5 hours for Dirk and Steve to have collected the same number of signatures.

A line through the points (2, 8) and (-2, k) has a slope of ¾. What is the value of k?
A line passing through the coordinates (2, 8) & (-2, k) does have a 34 slope. As a result, k has a value of 5.
A slope is what?The slope of a line governs its steepness. Rise over fall is a mathematical formula that describes slope.
We can construct an equation & solve for k using the slope formula:
if (x1, y1) & (x2, y2) are indeed the provided locations, slope is defined as (y2 – y1)/(x2 - x1).
Inputting the specified values results in:
¾ = (k - 8)/(-2 - 2) (-2 - 2)
By condensing this equation, we obtain:
3/4 = (k - 8)/(-4) (-4)
The result of multiplying all sides by -4 is:

Note that one of the x-values is negative. Find Σ [ x • P(x)]
Using the expected value of probability formula, the value of Σ[x•P(x)] is -0.65
What is the value of Σ[x•P(x)]The expected value of a probability distribution is a measure of the central tendency of the distribution. It is also known as the mean or the average value of the distribution.
To calculate the expected value, we multiply each possible outcome by its corresponding probability and then sum up the products. Symbolically, if X is a random variable with possible outcomes x1, x2, ..., xn and probabilities p1, p2, ..., pn, then the expected value of X, denoted E(X), is given by:
[tex]E(X) = \sum_{i=1}^{n} x_i p_i[/tex]
To find Σ[x•P(x)] we need to multiply each x-value by its corresponding probability and then sum up the products.
So we have:
Σ[x•P(x)] = (-1)(0.999) + (349)(0.001)
Σ[x•P(x)] = -0.999 + 0.349
Σ[x•P(x)] = -0.65
Therefore, Σ[x•P(x)] is equal to -0.65.
