U= {1, 2, 3, ... ,6}
A = {1, 3, 4, 6}
B={1, 2, 3)
C = {2, 3, 4, 5, 6}
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
OA. (AUBUC)' = {}
(Use a comma to separate answers as needed. Use ascending order.)
B. (A UBUC)' is the empty set.
Answer:
Step-by-step explanation:
A. (AUBUC)' = {}
B. (A UBUC)' is the empty set.
Both options A and B express that the complement of the union of the sets A, B, and C is the empty set. The complement of a set is the set of all elements that are not in that set. The union of sets is the set of all elements that are in at least one of the sets.
When taking the union of A, B, and C all the elements in U are included, so there is no element that is not in the set, making the complement of the union of A,B,C is an empty set.

As lengths of two sides XYZ are 23 and 48 inches
The range of the third side can be computed when we already know the two sides of the triangle.
If subtracting 48 - 23, the 3rd side would have to be more than 25. Else 3rd side can not be made as two smaller legs will not meet.
and If adding 48 + 23 , the 3rd side would have to be less than 61. Else 3rd side will reach further than the other two sides could reach.

The evaluation of the velocity function, v(t) = cos((π/6)·t) for the interval 0 ≤ t ≤ 12, th obtain the position and acceleration is as follows;
(a) The particle is moving to the left when 3 < t < 9

(c) a(t) ≈ -0.453

What is the acceleration of an object?Acceleration is the rate at which the velocity of the object changes.
The function for the velocity of the particle is presented as follows;
v(t) = cos((π/6)·t)
The position of the particle at time, t = 0 is x = -2
(a) When the particle is moving to the left, the velocity is negative
The value of cos(θ) is negative for π/2 < θ < 1.5·π
The range of values of θ = ((π/6)·t), for 0 ≤ t ≤ 2, are;
((π/6) × 0) ≤ θ ≤ ((π/6) × 12), from which we get;
0 ≤ θ ≤ (2·π)
When π/2 = (π/6)·t, we get;
t = (π/2)/(π/6) = 3
When 1.5·π = (π/6)·t, we get;
t = (1.5·π)/(π/6) = 9
The particle is moving to the left between time t = 3 and time t = 9, which can be expressed as follows;
The particle is moving to the left in the interval; 3 < t < 9(b) The total distance traveled by the particle from time t = 0 to time t = 6 is presented using the definite integral as follows;
Distance traveled = [tex]\int\limits^6_0 {cos(\frac{\pi}{6}\cdot t) } \, dt[/tex](c) Acceleration, a, is the rate of change of the velocity, therefore, the acceleration is the derivative of the velocity function, which can be obtained as follows;
[tex]a(t) =\frac{d}{dt} {cos(\frac{\pi}{6}\cdot t) } = -\frac{\pi}{6} \cdot sin(\frac{\pi}{6} \cdot t)[/tex]
[tex]a(t) = -\frac{\pi}{6} \cdot sin(\frac{\pi}{6} \cdot t)[/tex]
At time t = 4, we get;
[tex]a(4) = -\frac{\pi}{6} \cdot sin(\frac{\pi}{6} \times 4) = -\frac{\sqrt{3} \cdot \pi}{12}[/tex]
The acceleration of the particle at time t = 4 is; -(√3)·π/(12) ≈ -0.453(d) The position of the particle at time t = 4, can be obtained by adding the the position of the particle at time t = 4 to the total distance covered between time t = 0 and time t = 4 as follows;
[tex]\int\limits^4_0 {cos(\frac{\pi}{6}\cdot t) } \, dt =[ \frac{6}{\pi}\cdot {sin(\frac{\pi}{6}\cdot t) }]^4_0[/tex]

Write the equation of a line perpendicular to y=-2x+1 that passes through the point (-4,3)
Answer:
A line that is perpendicular to the line y=-2x+1 will have a slope that is the negative reciprocal of -2, which is 1/2.
The equation of a line in point-slope form is:
y - y1 = m(x - x1)
Where m is the slope of the line, and (x1, y1) is a point on the line.
Given that the point (-4,3) lies on the line, we can substitute those values for x1 and y1:
y - 3 = 1/2(x + 4)
Which is the equation of a line that is perpendicular to y=-2x+1 that passes through the point (-4,3).
Alternatively, you can also write the equation of a line in slope-intercept form y = mx + b,
The slope of a line perpendicular to y=-2x+1 is 1/2, therefore m = 1/2
We can substitute the point (-4,3) in the equation y = mx + b,
3 = (1/2)(-4) + b
b = 3.5
Therefore the equation of the line is y = 1/2x + 3.5

What is define by Pythagoras theorem?Pythagoras theorem is a mathematical statement that states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the two other sides (the legs).
It can be expressed as a2 + b2 = c2, where a and b are the two legs of the triangle and c is the hypotenuse. The theorem is named after the ancient Greek mathematician Pythagoras, who is believed to have discovered it.
Pythagoras theorem is an important concept in geometry, and is used to calculate the length of the hypotenuse in a right triangle when the lengths of the other two sides are known.
It can also be used to determine the lengths of the other two sides when the length of the hypotenuse is known. In addition, it can be used to find the angles of a right triangle when the lengths of the sides are known.
Pythagoras theorem has many applications in everyday life. For example, it can be used to calculate the height of a building, or the distance between two points.
It can also be used in carpentry, engineering, and architecture to measure distances and angles. In addition, it can be used in trigonometry to find the values of trigonometric functions.
Finally, it can be used in navigation to calculate distances and angles.
Let c be the length of missing side,
According to Pythagoras theorem,
a² + b² = c²
36² + 15² = c²
c = √1521
c = 39
So, the length of missing side is 39.

The base radius and height of a circular cone are measured as 10cm
and 25cm respectively, with a possible error in measurement of as much as 0.1cm in
each. Using linear approximation, estimate the magnitude of maximum error in the
calculated volume of the cone.
The maximum error in the volume of the cone is approximately 20π cubic centimeters.
How to determine the magnitude of maximum error in the volume of the cone
In this problem we must estimate the maximum error in the volume of the cone, based on uncertainties in radius and height of a circular cone. The volume formula for a circular cone is:
V = (π / 3) · R² · h
Where:
R - Base radius, in centimeters. h - Height, in centimeters.V - Volume, in cubic centimeters.And the maximum error formula (ΔV), in cubic centimeters, is found by total differentials:
ΔV = (dV / dR) · ΔR + (dV / dh) · Δh
Where:
(dV / dR) - First derivative of function volume respect radius, in square centimeters.(dV / dh) - First derivative of function volume respect height, in square centimeters.ΔR - Maximum uncertainty for radius, in centimeters. Δh - Maximum uncertainty for height, in centimeters.All first derivatives are shown below:
dV / dR = (2π / 3) · R · h
dV / dh = (π / 3) · R²
If we know that R = 10 cm, h = 25 cm, ΔR = 0.1 cm and Δh = 0.1 cm, then the maximum error in volume of circular cylinder is:
dV / dR = (2π / 3) · (10 cm) · (25 cm)
dV / dR = 500π / 3 cm²
dV / dh = (π / 3) · (10 cm)²
dV / dh = 100π / 3 cm²
ΔV = (500π / 3 cm²) · (0.1 cm) + (100π / 3 cm²) · (0.1 cm)
ΔV = 20π cm³

solve for x in the logarithmic function f(x)= 3-4 In (x-2)
Answer: In order to solve for x, we will have to use the logarithmic properties to isolate x.
f(x) = 3 - 4 In (x-2)
To solve for x, we will have to get x alone on one side of the equation by using the logarithmic property that logb(a^c) = c*logb(a).
4 In (x-2) = 3
In (x-2) = 3/4
To find x, we will raise e to the power of both sides
x-2 = e^(3/4)
x = e^(3/4) + 2
So the solution of x is e^(3/4) + 2
It's important to notice that the natural logarithm (ln) and log base e (In) are same and the solution is valid for both.

Step-by-step explanation:
A pen in the shape of an isosceles right triangle with legs of length x feet and hypotenuse of length h feet is to be built. If fencing costs $5 per feet for the legs and $10 per feet for the hypotenuse, write the total cost C of construction as a function of h.
The total cost C of construction as a function of h is:
[tex]C = \frac{10 + 5\sqrt{2}~ h^2}{h}[/tex]
As the pen is in the shape of an isosceles right angle, one of the
angle must be 90 degrees.
Also, the two sides of the triangle are equal and the base angles
are equal.
Here, x represents the length of legs of isosceles right triangle
and h be the length of hypotenuse of isosceles right triangle
Using Pythagoras theorem,
x² + x² = h²
2x² = h²
x² = h² / 2
x = [tex]\sqrt{\frac{h^2}{2} }[/tex]
So, x = [tex]\frac{h}{\sqrt{2} }[/tex]
The fencing costs $5 per feet for the legs and $10 per feet for the hypotenuse.
So, the fencing cost for the legs would be,
= 5 × (2x)
= 10x
= [tex]10\times \frac{h}{\sqrt{2} }[/tex]
= [tex]5\sqrt{2}~ h[/tex]
And the fencing cost for the hypotenuse would be,
= 10/ h
So, the total cost of fencing C would be,
[tex]C = \frac{10}{h} + 5\sqrt{2}~ h\\\\C = \frac{10 + 5\sqrt{2}~ h^2}{h}[/tex]

What is Distance?Distance between two points or objects can sometimes be measured qualitatively and sometimes quantitatively.
In physics, the concept of distance can refer to a physical length or, more commonly, to an approximation based on several other considerations.
The term is frequently used metaphorically to denote a measure of the degree of separation or statistical distance between two similar objects (such as edit distance between strings of text or distance between probability distributions), given that spatial cognition is a rich source of probability metaphors in human thought (as exemplified by distance between people in a social network).
Most of these literal and figurative concepts of distance are defined in terms of a mathematical idea called a metric space.

report error suppose the ratio of lev's age to mina's age is $1 : 2$ and the ratio of mina's age to naomi's age is $3 : 4$. if the sum of all three ages is between $30$ and $50$, then how old is mina? note: all ages are calculated to the nearest whole year.
As per the given ratio Mina's age is 12 years old.
Ratio in math is defined as shows how many times one number contains another.
Here we have given ratio information as written as
=> Lev's age : Mina's age = 1 : 2
And the ratio between is written as
=> Mina's age : Naomi's age = 3 : 4
Here we have given the condition that the sum of all three ages is written as,
=> Lev + Mina + Naomi = 30 to 50
Here let us consider Lev's age as L, Mina's age as M and Naomi's age as N
Then the ratio is calculated as,
=> L = 1/2M
=> N = 4/3M
And the sum of all value is written as
=> L + M + N = 30 to 50
When we apply the values on it, then we get,
1/2M + M + 4/3M = 30 to 50
When we simplify it by multiply all by 6, then we get
=> 3M + 6M + 8M = 180 to 300
=> 17M = 180 to 300
Therefore, here we have to find a number between 180 and 300 that divisible by 17 and 6.
So let us consider that that number is 204.
Then the value of M is calculated as,
=> 17M = 204
=> M = 12
Complete question:
Let us consider that suppose the ratio of lev's age to mina's age is 1 : 2 and the ratio of mina's age to Naomi's age is 3 : 4. if the sum of all three ages is between 30 and 50, then how old is mina?

the graphs of f and g are given. use them to evaluate each limit, if it exists. (if an answer does not exist, enter dne.)
The limit will be ,lim x→2 [f(x) + g(x)] = 2 + 0 = 2
In Mathematics, a limit is defined as a value that a function approaches the output for the given input values. Limits are important in calculus and mathematical analysis and used to define integrals, derivatives, and continuity. It is used in the analysis process, and it always concerns about the behaviour of the function at a particular point. The limit of a sequence is further generalized in the concept of the limit of a topological net and related to the limit and direct limit in theory category. Generally, the integrals are classified into two types namely, definite and indefinite integrals. For definite integrals, the upper limit and lower limits are defined properly. Whereas in indefinite the integrals are expressed without limits, and it will have an arbitrary constant while integrating the function.
lim x→2 means what is the value of y as x approaches 2 from the left side and the right side - they must be the same value for the limit to exist. "Approaches" is the operative word - it does not have to exist at that y-value, as in example a. lim x→1 [g(x)] = DNE because (left side of 1) lim x→1- [g(x)] = 2 and (right side of 1) lim x→1+ [g(x)] = 1

1. What’s the percentile of someone who earns $78 thousand dollars ?
2. How did you find the percentile ?
3. What does this value mean in the context of the problem ?
To find the percentile, we need to calculate what percentage of the data falls below the $78 thousand dollars wage.
What is percentile?
A percentile is a value that separates a data set into 100 equal parts.It represents the value below which a certain percentage of observations in a data set falls.For example, if a person's wage is in the 80th percentile, it means that 80% of the people in the data set earn less than that person, and 20% earn more.Percentiles can be used to summarize and describe the distribution of a set of data.They are often used in statistics and data analysis to compare values and measure the spread of data.
To find the percentile, we sort the data in ascending order and find the percentage of the data that falls below $78 thousand dollars. Here's one way to do this:
69 58 43 43 43 51 57 57 62 68 69 75 76 78 78 80 91 97 102 124 130 135 144 157 185 217
Out of 28 observations, 22 of them are below $78 thousand dollars. So, the percentile for someone who earns $78 thousand dollars is 22/28 * 100 = 78.5714.
In this context, the value of the percentile represents the percentage of the population of full-time employed people who hold at least a Bachelor's degree and earn less than $78 thousand dollars. So, someone who earns $78 thousand dollars is in the 78.5714th percentile of this population.

The domain is: a = -4, and b = 1 and the y = mx + b rule that makes the left (red) piece of the graph is given by y = -0.5x - 2.
What is domain and range?The range of values that can be plugged into a function is known as its domain. In a function like f, this set represents the x values (x).
The collection of values that a function can take on is known as its range. The values that the function outputs when we enter an x value are in this set. They are the values for y.
The domain of the left (red) graph is determined using the x-coordinates of the line. The x-coordinates give the input of the function of the graph, which forms the domain.
The domain is:
a = -4, and
b = 1
Hence, the domain of the function of the graph is: -4 < x <1.
The y = mx + b is the equation of the linear function where, m is the slope and b is the point where the line intersects the y-axis.
The value of m - slope is given by:
m = (y2 - y1) / (x2 - x1)
m = (-2.5 - 0) / (1 - (-4))
m = -2.5/ 5
m = - 0.5
The value of b from the graph is:
b= -2
Substituting the values of m and b in the equation we have:
y = mx + b
y = -0.5x - 2
Hence, the y = mx + b rule that makes the left (red) piece of the graph is given by y = -0.5x - 2.

The resistance y in ohms of 1000 feet of solid copper wire at 77°F can be approximated by the model y = 10770/x² - 0.37, 5 ≤ x ≤ 100 where x is the diameter of the wire in mils (0.001 in.). Use a graphing utility to graph the model. By about what factor is the resistance changed when the diameter of the wire is doubled?
The model's graph, y = 10770/x2 - 0.37, 5 x 100 demonstrates that the resistance will be about halved when the wire's diameter is doubled. This is brought on by the inverse square relationship between wire resistance and diameter.
1. Graph the model y = 10770/x² - 0.37, 5 ≤ x ≤ 100 using a graphing utility.
2. Find the resistance when x is 5.
y = 10770/5² - 0.37 = 2104.1 ohms
3. Find the resistance when x is 10.
y = 10770/10² - 0.37 = 526 ohms
4. Divide 2104.1 by 526 to find the factor by which the resistance is changed when the diameter of the wire is doubled.
2104.1/526 = 4
The graph of the model y = 10770/x² - 0.37, 5 ≤ x ≤ 100 shows that the resistance of the wire decreases as the diameter of the wire increases. Doubling the diameter of the wire will roughly halve the resistance, as can be seen by comparing the resistance when x is 5 (2104.1 ohms) to the resistance when x is 10 (526 ohms). Thus, the resistance is changed by a factor of 4 when the diameter of the wire is doubled.
