A regular pentagon ABCDE is shown.
Work out the size of angle x.
D

B
Answers
The value of the angle x of the given pentagon is: x = 36°
How to find the angle in the polygon?The formula to find the interior angle of a regular polygon is:
θ = 180(n - 2)/n
where n is number of sides of polygon
In this case we have a pentagon which has 5 sides. Thus:
θ = 180(5 - 2)/5
θ = 540/5
θ = 108°
Now, the sides of the pentagon are equal and as such the triangle formed ΔBDC is an Isosceles triangle where:
∠BDC = ∠DBC
Thus:
x = (180 - 108)/2
x = 72/2
x = 36°

2. Indicate whether the following statement is sometimes true, always true or never true. Justify you response. "If f(x) is defined for all × ≤R, then f'(x) is also defined for all × = R." (2 mark
Answers
The statement "If f(x) is defined for all x ≤ R, then derivative f'(x) is also defined for all x = R" is sometimes true.
The first part states that "f(x) is defined for all x ≤ R." This means that the function f(x) is defined and exists for every value of x that is less than or equal to R. In other words, the function is defined in the interval (-∞, R].
The second part of the statement says that "f'(x) is also defined for all x = R." Here, f'(x) represents the derivative of the function f(x). It states that the derivative of f(x) exists and is defined at x = R.
The key point to consider is that the existence and differentiability of a function at a specific point are not dependent on the entire interval in which the function is defined. In other words, just because a function is defined for all x ≤ R does not necessarily mean that its derivative will be defined at x = R.
Therefore, it is possible for the statement to be true in some cases, where the derivative exists at x = R, but it is not always true. The truthfulness of the statement depends on the specific properties and behavior of the function f(x) and its derivative f'(x) in the vicinity of x = R.

I am confused how they were able to get the constraints in ch6
problem 10P
Answers
In Chapter 6, Problem 10P, the constraints are derived based on the given problem scenario and the objective of the optimization problem. Without specific details about Problem 10P in Chapter 6, it is challenging to provide a precise explanation.
However, I can provide a general understanding of how constraints are typically formulated in optimization problems. In optimization problems, constraints are used to represent the limitations or restrictions on the decision variables. These constraints can arise from various sources, such as physical constraints, resource constraints, budget constraints, or technical constraints. To derive the constraints, you need to carefully analyze the problem statement and identify the conditions or limitations that must be satisfied. These conditions are then translated into mathematical inequalities or equations that relate the decision variables. For example, if the problem involves allocating limited resources among different activities, the constraints would represent the availability of those resources and ensure that the total allocation does not exceed the available amount. Similarly, if the problem involves production planning, constraints might include demand requirements, capacity limitations, or inventory constraints. In general, the process of formulating constraints requires careful consideration of the problem's requirements, objectives, and limitations. It often involves translating real-world constraints into mathematical expressions to create a well-defined optimization problem that can be solved using appropriate techniques.

d) purposive
Answers
The variety of nonrandom sampling that takes proportions into consideration is: c) quota
Quota sampling is the variety of nonrandom sampling that takes proportions into consideration. In quota sampling, the researcher selects a specific number of participants from each subgroup of the population based on their proportion in the overall population. This ensures that the sample represents the different subgroups in the population proportionately.
In quota sampling, the researcher selects participants based on specific characteristics or proportions to ensure that the sample represents the target population accurately. The researcher sets quotas for different groups or segments based on known proportions or desired representation in the population.
For example, if a population consists of 60% males and 40% females, a quota sample might be designed to include the same proportions of males and females. The researcher would continue to select participants from each group until the quotas are met.

Answers
Using logarithmic properties, the solution to the given logarithmic equation is y = 7
Solving Logarithmic equationsFrom the question, we are to determine the solution to the given equation
The given equation is
\(log_{11}(y+8) + log_{11}(4) = log_{11}(60)\)
Applying the product law of logarithms, we get
\(log_{11}(y+8) \times (4) = log_{11}(60)\)
This gives

the area of the shaded region is $78$ square inches. all angles are right angles and all measurements are given in inches. what is the perimeter of the non-shaded region?
Answers
The perimeter of the non-shaded region in the figure can be calculated to be 14 inches.
Given a figure.
The middle portion of the figure is not shaded.
It is required to find the perimeter of the non-shaded region.
It is given that:
The whole area of the shaded region = 78 inches²
The area of the small square which is situated at the bottom is:
Area of small square = 2 × 4
= 8 inches²
So, the area of the rest of the shaded area = 78 - 8
= 70 inches²
Now, the area of the whole region without the small square is:
Area = 10 × (10 - 2)
= 80 inches²
So, the area of the non-shaded region = 80 - 70
= 10 inches²
The width of the non-shaded rectangle is 2 inches.
So, length = 5 inches.
So, the perimeter is:
P = 2(5 + 2)
= 14 inches
Hence, the perimeter is 14 inches.

Answers
If n > N, we have |fn(xn) − f∗(x∗)| ≤ |fn(xn) − f∗(xn)| + |f∗(xn) − f∗(x∗)| + |f∗(x∗) − fn(x∗)| < ε/3 + ε/3 + ε/3 = ε.
Suppose that each fn: R → R is continuous on a set A, and (fn) converges to f∗ uniformly on A.
Let (xn) be a sequence in A converging to x∗ ∈ A. Show that (fn(xn)) converges to f∗(x∗).Solution: Let ε > 0 be arbitrary.
We must show that there exists an index N such that if n > N, then |fn(xn) − f∗(x∗)| < ε. We know that (fn) converges uniformly to f∗ on A.
Hence, there exists an index N1 such that if n > N1, then |fn(x) − f∗(x)| < ε/3 for all x ∈ A.
Also, by continuity of f∗ at x∗, there exists a δ > 0 such that if |x − x∗| < δ, then |f∗(x) − f∗(x∗)| < ε/3.
Since (xn) converges to x∗, there exists an index N2 such that if n > N2, then |xn − x∗| < δ.
Let N = max{N1, N2}. Then, if n > N, we have |fn(xn) − f∗(x∗)| ≤ |fn(xn) − f∗(xn)| + |f∗(xn) − f∗(x∗)| + |f∗(x∗) − fn(x∗)| < ε/3 + ε/3 + ε/3 = ε.

Answer:

Step-by-step explanation:
so O must be 0,0 and A is a midpoint of OB
This means B must be (14,12)
B is the midpoint of TS.
This means that the distance of SB is equal to the distance of BT.
This must mean that the coordinate of T must be (3,20)
O: (0,0) x coordinate increases by 7. y coordinate increases by 6.
A: (7,6)
B: (14,12)
S: (25,4) x coordinate decrease by 11. y coordinate increases by 8.
B: (14,12)
T: (3,20)
The coordinates of T are (3, 20).
What is Straight Line?A straight line is an endless one-dimensional figure that has no width.
From the figure, A is the midpoint of OB and B is the midpoint of TS
The coordinates of O are (0, 0) and Coordinates of A are (7,6)
We can find coordinate of B.
(7, 6)=(0+x/2, 0+y/2)
(7,6)=(x/2, y/2)
x/2=7 and y/2=6
x=14 y=12
So the coordinates of B are (14, 12)
Now we can find the coordinates of T.
(14, 12)=(X+25/2, Y+4/2)
X+25=28
x=3
Y+4=24
Y=20
So the coordinates of T are (3, 20)
Hence, the coordinates of T are (3, 20).

2x+2yequals 5, x-2y equals 3 find the solution set by using method elimination by substitution
Answers
The solution set of the given system of equations is {(8/3, -1/6)}.
We are given the following system of linear equations:
2x + 2y = 5 ...(1)
x - 2y = 3 ...(2)
We can use the method of elimination by substitution to solve this system. First, we solve equation (2) for x in terms of y:
x = 2y + 3
Substituting this value of x in equation (1), we get:
2(2y + 3) + 2y = 5
Simplifying the above expression, we get:
6y + 6 = 5
6y = -1
y = -1/6
Substituting this value of y in equation (2), we get:
x - 2(-1/6) = 3
x + 1/3 = 3
x = 8/3
Therefore, the solution set of the given system of equations is:

A single tractor-trailer driver is starting a new shift, intending to travel 450 miles from Charlotte, NC to Pittsburgh, PA. Estimating an average speed of 50 mph and abiding by the current HOS rules, what is the minimum number of clock hours (not driving hours) it will take him?
Answers
It will take a minimum of 10 clock hours (not driving hours) for the truck driver to travel 450 miles from Charlotte, NC to Pittsburgh, PA.
The current Hours of Service (HOS) rules for truck drivers stipulate that a truck driver cannot drive for more than 11 hours after 10 consecutive hours off duty.
Additionally, the driver is not allowed to drive beyond 14 hours after coming on duty.
The driver's shift includes both driving and non-driving time.
Therefore, it is necessary to consider the total amount of time spent on the job.
The truck driver will have to stop for rest breaks, refueling, or other reasons during the 450-mile journey to Pittsburgh, Pennsylvania. The driver is required to take a 30-minute break after eight hours of driving.
Therefore, the minimum number of clock hours (not driving hours) it will take the truck driver to travel the 450-mile distance from Charlotte, NC to Pittsburgh, PA is calculated as follows:
Time for the trip = (Distance ÷ Average Speed) + Breaks
Time for the trip = (450 ÷ 50) + (30 ÷ 60) × 2
Time for the trip = 9 + 1
Time for the trip = 10 clock hours
Therefore, it will take a minimum of 10 clock hours (not driving hours) for the truck driver to travel 450 miles from Charlotte, NC to Pittsburgh, PA.

There are three ways to name an angle--by its vertex, by the three points of the angle (the middle point must be the vertex), or by a letter or number written within the opening of the angle.
You can name a specific angle by using the vertex point, and three points on each of the angle's rays or by letter or number written. The name of the angle is simply the three letters representing those points, with the vertex point listed in the middle. You can also name angles by looking at their size. Right angles are 90 degrees. Acute angles are less than 90 degrees. Obtuse angles are greater than 90 degrees, but less than 180 degrees, which is a straight angle, or a straight line.

Find the indefinite integral: S(-7secxtanx - 5sec²x)dx
Answers
The value of the indefinite integral: S(-7secxtanx - 5sec²x)dx is -7ln|sec(x) + tan(x)| - 5x + 5ln|sec(x)| + C
To integrate the expression S(-7sec(x)tan(x) - 5sec²(x))dx, we first use the identity sec²(x) = 1 + tan²(x) to rewrite the second term as -5 - 5tan²(x). Then we can split the integral into two parts as follows: S(-7sec(x)tan(x) - 5sec²(x))dx = -7Ssec(x)tan(x)dx - 5S(1 + tan²(x))dx = -7sec(x)dx - 5x - 5tan(x)dx
Now we can integrate each part separately. The integral of sec(x) is ln|sec(x) + tan(x)| + C, and the integral of tan(x) is ln|sec(x)| + C. Therefore, S(-7sec(x)tan(x) - 5sec²(x))dx = -7ln|sec(x) + tan(x)| - 5x + 5ln|sec(x)| + C where C is the constant of integration.

Answers
The percent of scores are above 400 is 84.13 percent.
Given that, mean \((\bar{x})\)=500 and the standard deviation \((\sigma)\)=100.
Standard deviation is the positive square root of the variance. Standard deviation is one of the basic methods of statistical analysis. Standard deviation is commonly abbreviated as SD and denoted by 'σ’ and it tells about the value that how much it has deviated from the mean value.
Here, from the normalization curve the proportion of SAT scores above 400 is
\((50+\frac{68.26}{2})\%\)
\(= 84.13 \%\)
Therefore, the percent of scores are above 400 is 84.13 percent.
