By using the property of angle, it can be calculated that \(\angle EBA \cong \angle ECD\)
What are angles?
Angles are a way of measuring the amount of turn between two lines or three or more planes. An angle is formed when two lines intersect or when two planes meet. It is measured in degrees, with a full circle being 360 degrees. The angle is measured in terms of the amount of turn between the two lines or planes. Angles are typically used to describe the orientation of objects in space, such as the corners of a triangle, the angle of a flight path, or the angle of the sun’s rays. Angles are also used to measure the size of an angle and the distance between two points. Angles are important in mathematics because they help to analyze the size and shape of objects, and also to help solve problems.
Here,
It is given that
\(\angle EBC \cong \angle ECB\)

Answers
The statements supported by the data in the table are:
The mean number of cars sold in a month is the same at both dealerships.
The total number of cars sold is the same at both dealerships.
The data for Admiral Autos shows greater variability.
To determine which statements are supported by the data in the table, let's analyze the given information:
The mean number of cars sold in a month is the same at both dealerships.
To calculate the mean, we need to find the average number of cars sold each month at each dealership.
For Admiral Autos:
(4 + 19 + 15 + 10 + 17) / 5 = 65 / 5 = 13
For Countywide Cars:
(9 + 17 + 14 + 10 + 15) / 5 = 65 / 5 = 13
Since both dealerships have an average of 13 cars sold per month, the statement is supported.
The median number of cars sold in a month is the same at both dealerships.
To find the median, we arrange the numbers in ascending order and select the middle value.
For Admiral Autos: 4, 10, 15, 17, 19
Median = 15
For Countywide Cars: 9, 10, 14, 15, 17
Median = 14
Since the medians are different (15 for Admiral Autos and 14 for Countywide Cars), the statement is not supported.
The total number of cars sold is the same at both dealerships.
To find the total number of cars sold, we sum up the values for each dealership.
For Admiral Autos: 4 + 19 + 15 + 10 + 17 = 65
For Countywide Cars: 9 + 17 + 14 + 10 + 15 = 65
Since both dealerships sold a total of 65 cars, the statement is supported.
The range of the number of cars sold is the same for both dealerships.
The range is determined by subtracting the lowest value from the highest value.
For Admiral Autos: 19 - 4 = 15
For Countywide Cars: 17 - 9 = 8
Since the ranges are different (15 for Admiral Autos and 8 for Countywide Cars), the statement is not supported.
The data for Admiral Autos shows greater variability.
To determine the variability, we can look at the range or consider the differences between each data point and the mean.
As we saw earlier, the range for Admiral Autos is 15, while for Countywide Cars, it is 8. Additionally, the data points for Admiral Autos are more spread out, with larger differences from the mean compared to Countywide Cars. Therefore, the statement is supported.
Based on the analysis, the statements supported by the data are:
The mean number of cars sold in a month is the same at both dealerships.
The total number of cars sold is the same at both dealerships.
The data for Admiral Autos shows greater variability.

For a curve to be a density curve, it must meet certain conditions such as it should be non-negative, and the area under the curve should equal 1. Furthermore, the curve should be continuous and smooth, and there should be no values outside the range of the data.
Let's see how the height would need to be for this curve to be a density curve.A density curve is a statistical representation of the distribution of a dataset or population. Density curves are used to describe the distribution of continuous data and provide a visual representation of the likelihood of an event occurring within a specific range of values. It helps to determine the proportion of data that falls within a given range of values. A density curve is used to provide a graphical representation of data without showing the individual data points.To be a density curve, a curve must have the following properties:The curve should be non-negative.The area under the curve should be equal to 1.The curve should be smooth and continuous.There should be no values outside the range of the data.From the above properties, we can conclude that the height required for a curve to be a density curve depends on the data that the curve represents. As long as the curve meets the above conditions, it can be considered a density curve. So, there is no specific height required for a curve to be a density curve. The height of the curve can vary depending on the range of the data and the distribution of the data.For such more question on properties

How many gallons of a 50% antifreeze solution must be mixed with 70 gallons of 10% antifreeze to get a mixture that is 40% antifreeze?
Answers
Answer: 180 gallons needed
Step-by-step explanation:
Zykeith,
Assume x gallons of 50% antifreeze is needed
Final mixture is x + 60 gallons
Amount of antifreeze in mixture is 0.4*(x+60)
Amount of antifreeze added is .5x + .1*60 = .5x + 6
so .5x + 6 = .4(x + 60)
.5x -.4x = 24 -6
.1x = 18
x = 180
Let x be the number of gallons of the 50% antifreeze solution needed. We know that the resulting mixture will be 70 + x gallons. To get a 40% antifreeze mixture, we can set up the following equation:
\({\implies 0.5x + 0.1(70) = 0.4(70 + x)}\)
Simplifying the equation:
\(\qquad\implies 0.5x + 7 = 28 + 0.4x\)
\(\qquad\quad\implies 0.1x = 21\)
\(\qquad\qquad\implies \bold{x = 210}\)
\(\therefore\) We need 210 gallons of the 50% antifreeze solution to mix with 70 gallons of 10% antifreeze to get a mixture that is 40% antifreeze.

Give an example of a function F(x) that is an antiderivative of f(x) = 9 cos(9x)+ 3x^2
Answers
We are integrating f(x) = 9cos(9x) + 3x²: \(\int\ {9cos(9x)+3x^{2} } \, dx\)
a) Apply the sum rule
\(\int\9cos(9x)} \, dx +\int\ 3x^{2} } \, dx\)
b) Calculate each antiderivative
First integral
\(\int\ {9cos(9x)} \, dx\)
1. Take out the constant
\(9\int\ {cos(9x)} \, dx\)
2. Apply u-substitution, where u is 9x
\(9\int\ {cos(u)\frac{1}{9} } du\)
3. Take out the constant (again)
\(9*\frac{1}{9} \int{cos(u)} du\)
4. Take the common integral of cos, which is sin
\(9*\frac{1}{9}sin(u)}\)
5. Substitute the original function back in for u and simplify\(9*\frac{1}{9} sin(9x) = sin(9x)\)
6. Always remember to add an arbitrary constant, C, at the end
\(sin(9x) + C\)
Second integral
\(\int3x^{2} } \, dx\)
1. Take out the constant
\(3\int{x^{2} } \, dx\)
2. Apply the power rule, \(\int{x}^{a} \, dx =\frac{x^{a+1} }{a+1}\), where a is your exponent
⇒ \(3*\frac{x^{2+1} }{2+1} = x^{3}\)
3. Add the arbitrary constant
\(x^{3} + C\)
c) Add the integrals
sin(9x) + C + x³ + C = sin(9x) + x³ + C
Notice the two arbitrary constants. Since we do not know what either constant is, we can combine them into one arbitrary constant.
Answer:F(x) = sin(9x) + x³ + C
Answer:
\(g(x)=sin(9x)+x^3+C\), choose a constant that is any number you want for C
Step-by-step explanation:
So we have a function, \(f(x)=9cos(9x)+3x^2\) An antiderivative is also called an integral, so to find the antiderivative of f(x) we find the integralso we will say g(x) is equal to the integral (antiderivative) of f(x)Then \(g(x)=\int\ {(9cos(9x)+3x^{2}) } \, dx\) Which can be written as \(g(x)=\int\ {9cos(9x)} \, dx +\int\ {3x^{2} } \, dx\) So let's do the first part integral \(\int\ {9cos(9x)} \, dx\) which can be written as \(9*\int\ {cos(9x)} \, dx\) Then we use u substitution integration, and \(u=9x,\frac{du}{dx} =9,dx=\frac{1}{9}*du\) so we replace dx and 9x so that \(9*\int\ {cos(9x)} \, dx =9*\int\ {\frac{1}{9}cos(u) } \, du=9*\frac{1}{9}*\int\ {cos(u)} \, du\) Leaving \(\int\ {cos(u)} \, du=sin(u)+C\) then replace u with 9x, so \(sin(9x)+C\)Now for the second part integration\(\int\ {3x^2} \, dx =3 *\int\ {x^2} \, dx=3*\frac{x^{2+1}}{2+1}+C=3*\frac{x^{3}}{3}+C=x^3+C\) so \(g(x)=sin(9x)+C+x^3+C=sin(9x)+x^3+C\) so \(g(x)=sin(9x)+x^3+C\) is a general solution antiderivative to f(x)Simplify the expression: 2/3 (6e+9f-21g)

The length of z would be '8.89 cm'.
What is sine rule in triangle?
According to the law of sine, or sine law, the ratio of a triangle's side length to the sine of the opposing angle remains constant for all three sides.
Given that in ΔXYZ, x = 3.9 cm, ∠Y=68° and ∠Z=86°.
As we know sum of all angles of a triangle is 180.
∠X + ∠Y + ∠Z = 180°
∠X + 68° + 86° = 180°
∠X = 26°
Now by using sine law, we get
\(\frac{x}{sinX} = \frac{y}{sinY} = \frac{z}{sinZ}\)
\(\frac{x}{sinX} = \frac{z}{sinZ}\)
\(\frac{3.9}{sin26} = \frac{z}{sin86}\)
Simplifying this, we get
z = 3.9*0.99/0.438
z = 8.89

Answers
Answer:
The given function h has a domain of -3 ≤ x ≤ 11 and a range of 1 ≤ h(x) ≤ 25, and we also know that h(8) = 19 and h(-2) = 2.
Since we know the range of h(x) is 1 ≤ h(x) ≤ 25, statement B cannot be true because it suggests a value of h(x) outside of this range.
Statement A suggests that h(8) = 21, which is outside the given range for h(x). Therefore, statement A cannot be true.
Statement C suggests that h(2) = 16, but we do not have any information about the value of h(x) at x = 2. Therefore, statement C may or may not be true.
Statement D suggests that h(13) = 18, but 13 is outside the domain of h(x). Therefore, statement D cannot be true.

Fine Floors can install 15 square yards of carpeting in 4 hours 30 minutes. At this rate, how long would it take to install carpeting in a room that measures 11 feet 9 inches by 13 feet 4 inches?
Answers
Answer:
Step-by-step explanation:
To figure out how long it would take Fine Floors to install carpeting in a room that measures 11 feet 9 inches by 13 feet 4 inches, we first need to determine how many square yards of carpeting are needed for the room. We can start by converting the dimensions of the room from feet and inches to yards, since that's the unit of measurement we're working with.
To convert feet to yards, we divide by 3. For example, 11 feet is equal to 11/3 = 3.67 yards. To convert inches to yards, we divide by 36 (since there are 36 inches in a yard). For example, 9 inches is equal to 9/36 = 0.25 yards.
So the length of the room in yards is 3.67 + 0.25 = 3.92 yards, and the width of the room in yards is 13/3 + 4/36 = 4.33 + 0.11 = 4.44 yards.
To determine the total area of the room in square yards, we multiply the length and width: 3.92 * 4.44 = 17.38 square yards.
Now that we know how many square yards of carpeting are needed for the room, we can use that information to calculate how long it would take Fine Floors to install the carpeting. Since we know that Fine Floors can install 15 square yards of carpeting in 4 hours 30 minutes, we can use that as the ratio for our calculation.
To calculate how long it will take to install 17.38 square yards of carpeting, we use the proportion:
(15 sq. yards) / (4 hours 30 minutes) = (17.38 sq. yards) / (x hours)
Cross multiplying and solving for x, we find: x = (4 hours 30 minutes) * (17.38 sq. yards) / (15 sq. yards)
So it would take Fine Floors approximately 5 hours and 11 minutes to install carpeting in a room that measures 11 feet 9 inches by 13 feet 4 inches.
