The fractional part vanishes when the argument is an integer; in this case, for
[tex]\left\{\dfrac1{1-xy}\right\} = 0 \iff \dfrac1{1-xy} = n \iff xy = \dfrac{n-1}n[/tex]
which are hyperbolas in the [tex](x,y)[/tex]-plane.
Observe that between neighboring hyperbolas, we have
[tex]\dfrac{n-1}n < xy < \dfrac n{n+1} \\\\ ~~~~ \implies \dfrac1{n+1} < 1-xy < \dfrac1n \\\\ ~~~~ \implies n < \dfrac1{1-xy} < n+1 \\\\ ~~~~ \implies \left\{\dfrac1{1-xy}\right\} = \dfrac1{1-xy} - \left\lfloor\dfrac1{1-xy}\right\rfloor = \dfrac1{1-xy} - n[/tex]
Split up the integral over [tex][0,1)^2[/tex] along the curves [tex]xy=\frac{n-1}n[/tex]. The subregions somewhat resemble the layers or scales of an onion (see attached plot with the first 5 "scales").
Let [tex]S_n[/tex] denote the [tex]n[/tex]-th ([tex]n\in\Bbb N[/tex]) "scale", starting from the blue region closest to the origin and counting diagonally upward in the direction of (1, 1).
In Cartesian coordinates, the integral over [tex]n[/tex]-th "scale" is
[tex]\displaystyle \iint_{S_n} x \left(\frac1{1-xy} - n\right) \, dy \, dx \\\\\\ ~~~~~~~~= \int_{(n-1)/n}^{n/(n+1)} \int_{(n-1)/(nx)}^1 x \left(\frac1{1-xy} - n\right) \, dy dx \\\\\\ ~~~~~~~~~~~~~ + \int_{n/(n+1)}^1 \int_{(n-1)/(nx)}^{n/((n+1)x)} x \left(\frac1{1-xy} - n\right) \, dx[/tex]
(see attached plot of the 2nd "scale" for reference)
The integral is trivial, so I'll leave it to you to confirm that it drastically reduces to
[tex]\displaystyle \iint_{S_n} x \left(\frac1{1-xy} - n\right) \, dy \, dx = \frac1{2n (n+1)^2} = \frac12 \left(\frac1n - \frac1{n+1} - \frac1{(n+1)^2}\right)[/tex]
Now we recover the original integral by summing over [tex]\Bbb N[/tex].
[tex]\displaystyle \int_0^1 \int_0^1 x \left\{\frac1{1-xy}\right\} \, dy \, dx = \frac12 \sum_{n=1}^\infty \left(\frac1n - \frac1{n+1} - \frac1{(n+1)^2}\right) \\\\ ~~~~~~~~ = \frac12 \left(\left(1-\frac12\right)+\left(\frac12-\frac13\right)+\left(\frac13-\frac14\right)+\cdots\right) - \frac12 \sum_{n=2}^\infty \frac1{n^2} \\\\ ~~~~~~~~ = \frac12 - \frac12 \left(\sum_{n=1}^\infty \frac1{n^2} - 1\right) \\\\ ~~~~~~~~ = \frac12 - \frac12 \left(\frac{\pi^2}6 - 1\right) = \boxed{1 - \frac{\pi^2}{12}}[/tex]

convert each of the following base-ten numberals in the indicated bases
456 in base 5
Answers
Answer:
3311
Step-by-step explanation:
The steps are as follows
1. Divide 456 by 5. This gives a quotient of 91 with a remainder of 1. This remainder becomes the least significant digit of the new base number. This would be the right most digit. So the number is _ _ _ 1
2. Take the quotient, 91, divide by 5 again. This gives a quotient of 18 with a remainder of 1. Put this remainder to the immediate left of the previous value. So we have the number as _ _ 1 1
3. Take the previous quotient, 18, divide by 5 again. 18/5 gives quotient of 3 with a remainder of 3. Put this to the immediate left of the previous number giving the number as _ 3 1 1
4. Repeat the division of the new quotient by 5. 3/5 gives a quotient of 0 with remainder of 3 so we stop
Number = 3 3 1 1

If it is asking you for the whole triangle then 180, all triangles equal 180 degrees
Answer:
angle A=125 angle B= 114 angle C= 121
Step-by-step explanation:
first you have to find x so that you can find each angle
the interior angles of a triangle is equal to 360
add the angles together x+x+7+x+11=360
combine like terms 3x+18=360
subtract 18 on both sides 3x=342
divide by 3 on both sides x=114
to find angles:
plug in X to each side
(114)+7 = angle C
(114)+11= angle A
114= angle B

What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Division = divide any two numbers or variable called division.
Let's consider a division problem.
5/2 → 2 + 1
Here 5 is called the dividend,2 is the divisor,2 is the quotient, and 1 is the remainder.
Now,
2 × 2 + 1 = 5
Therefore,divisor × quotient + remainder = dividend
So,
Let's suppose the divisor in the given case is x
Now,
52x + 18 ≥ 1000
52x ≥ 982
x ≥ 18.86

Three adults and four children must pay $116
Two adults and three children must pay $82
Find the price of the adult's ticket and the price of a child's ticket.
Answers
The price of the adult's ticket is $20 and the price of a child's ticket is $14.
How to calculate the valuesLet adults = a
Let children = c
The appropriate equation will be:
3a + 4c = 116
2a + 3c = 82
Multiply equation I by 2
Multiply equation ii by 3
6a + 8c = 232
6a + 9c = 246
Subtract
c = 14
Price for children = 14
Since 2a + 3c = 82
2a + 3(14) = 82
2a + 42 = 82
2a = 82 - 42
2a = 40.
a = 40/2
a = 20
Therefore, the price of the adult's ticket is $20 and the price of a child's ticket is $14.

The times associated with each speed are:
20 h10 h6.667 h5 h4 hIt is always true that the speed is inversely proportional to time.
How to analyze the motion of a bicycle at constant speed
In this case we find the situation of bicycle moving at constant speed, where the traveled distance (s), in miles, is equal to the following expression:
s = v · t (1)
Where:
v - Speed, in miles per hour.t - Time, in hourNow we proceed to calculate time needed for each speed:
t = s / v
Case 1
t = 100 mi / 5 mi / h
t = 20 h
Case 2
t = 100 mi / 10 mi / h
t = 10 h
Case 3
t = 100 mi / 15 mi / h
t = 6.667 h
Case 4
t = 100 mi / 20 mi / h
t = 5 h

Consider a set of data in which the sample mean is 30.9 and the sample standard deviation is 7.7. Calculate the z-score given that x = 31.1. Round your answer to
two decimal places.
Answers
The value of the z-score is calculated as 0.259.
What is descried as normal distribution?The standard normal distribution is the variable of a normal distribution to mean 0 and variance 1. The normal distribution follows a bell curve. The z-table aids in determining the area beneath the curve.
The normal distribution is also known as the Gaussian distribution, after just a German mathematician.The t-distribution is another distribution that may be described as having a bell shape. It differs as from normal distribution in that the tails are thicker. It is commonly employed in the analysis of small sample size datasets.Now, as per the given question;
The formula for the z-score is;
z = (x - μ)/σ
x = sample size
σ = standard deviation
μ = mean of the sample
For the given values in the question;
x = 31.1
σ = 7.7
μ = 30.9
Substitute the given values in the formula to fine z-score;
z-score = (31.1 - 30.9)/7.7
z-score = 0.259
Therefore, the value of the z-score is computed as 0.259.

If angle YXZ measures 90 degrees, which statement is true?
(answers are below)
segment XZ is perpendicular to segment WY
WX =XY
segment XZ is a perpendicular bisector of segment WY
X is the midpoint of segment WY
Answers
The true statement about the given diagram is: A. segment XZ is perpendicular to segment WY.
What are Perpendicular Segments?Perpendicular segments are line segments that intersect at a point to form right angles which is equal to 90 degrees. The point where perpendicular segments meet have an angle measure of 90 degrees.
In the given diagram, we are told that angle YXZ is equal to 90 degrees. This means that at the point where segment XZ and segment WY meet have an angle measure of 90 degrees.
This means they are perpendicular segments.
Therefore, the true statement about the given diagram is: A. segment XZ is perpendicular to segment WY.

Answers
Car A consumes 11.9 gallons.
Car B consumes 13 gallons
Car A consumes 16.3 gallons
Car B consumes 11.6 gallons
How many gallons would be used?In order to determine the required values, the mathematical operation that would be used is division. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.
Gallons that would be consumed when driving 300 mi of city driving plus 100 mi of highway driving:
For Car A = (300 / 36) + (100 / 28) = 11.9 gallons
For Car B: (300 / 29) + (100 / 37) = 13 gallons
Gallons that would be consumed when driving 100 mi of city driving plus 300 mi of highway driving:
For Car A = (100 / 36) + (300 / 28) = 16.3 gallons
For Car B: (100 / 29) + (300 / 37) = 11.6 gallons
