Calculate the double integral.
∫ 4x / 1+xy
R dA, R=[0,4] × [0,1]
Answers
The double integral for this problem has the result given as follows:
[tex]\int_{0}^4 \int_0^1 \frac{4x}{1 + xy} dy dx = 20\ln{(5)} - 16[/tex]
How to calculate the double integral?Considering the variable y as the inner variable, the double integral is defined as follows:
[tex]\int_{0}^4 \int_0^1 \frac{4x}{1 + xy} dy dx[/tex]
We start calculating the inner integral, as follows:
[tex]I = \int_0^1 \frac{4x}{1 + xy} dy[/tex]
Using substitution, we have that:
u = 1 + xy
du = x dy.
dy = du/x
Hence:
[tex]I = \int \frac{4x}{u} \times \frac{du}{x}[/tex]
[tex]I = 4\int \frac{1}{u} du[/tex]
I = 4 ln(u).
Returning to x and y, we have that:
I = 4 ln(1 + xy), from y = 0 to y = 1.
Applying the Fundamental Theorem of Calculus for the definite integral, we have that:
I = 4 ln(1 + x) - 4 ln(1 + 0)
I = 4ln(1 + x).
Then the outer integral is given as follows:
[tex]O = \int_{0}^4 4 \ln{(1 + x)} dx[/tex]
Hence:
O = 4[ln(1 + x) + xln(1 + x) - 1 - x], from x = 0 to x = 4.
Applying the Fundamental Theorem again, now for the variable x, we have that:
O = 4[ln(5) + 4ln(5) - 1 - 4] - 4[ln(1) + 0ln(1) - 1 - 0]
O = 4[5ln(5) - 5] + 4
O = 20ln(5) - 20 + 4
O = 20ln(5) - 16.

Answers
The work done by a force [tex]$\overrightarrow{\mathrm{F}}=(\hat{\mathrm{i}}+2 \hat{\mathrm{j}}+3 \hat{\mathrm{k}}) \mathrm{N}$[/tex], to displace a body from position A to position B is 5j
What is force?A force in physics is an effect that has the power to alter an object's motion. A mass-containing object's velocity can vary, or accelerate, as a result of a force. Intuitively, a push or a pull can also be used to describe force. Being a vector quantity, a force has both magnitude and direction. The normal force operates in the opposite direction from how surfaces interact with one another. A force called friction prevents motion on surfaces. Other non-fundamental forces include the Coriolis force, the elastic force, tension, and frame-dependent forces like centrifugal force.Now basically here we, are talking about the work done by a body in the form of displacement.
This displacement is done due to the force that acted upon the body.
To calculate the work done we use the formula as,
W = F.ds
where F is the force acted on the body and the 'ds' is the displacement vector or the factor,
thus we calculate 'ds' as
AB vector = r2 - r1
AB = (2i + 2j +3k ) - ( i+3j+k)
so we get as,
AB = i -j +2k
now substituting in the formula we get as
W = (i + 2j + 3k ) .(i - j +2k)
W = 1 -2 +6
W = 5 joules
Work done = 5 J
The complete question is,
The work done by a force [tex]$\overrightarrow{\mathrm{F}}=(\hat{\mathrm{i}}+2 \hat{\mathrm{j}}+3 \hat{\mathrm{k}}) \mathrm{N}$[/tex], to displace a body from position A to position B is : [The position vector of A is [tex]$\overrightarrow{r_1}=(\hat{i}+3 \hat{\jmath}+\hat{k}) \mathrm{m}$[/tex] and the position vector of B is [tex]$\left.\overrightarrow{r_2}=(2 \hat{i}+2 \hat{j}+3 \hat{\mathbf{k}}) \mathrm{m}\right]$[/tex]

45. A blueprint for a house has a scale of 1:55. A wall in the blueprint is 6 in. What is the length of
the actual wall?
330 ft.
110 ft.
27.5 in.
027.5 ft.
Answers
Answer:
the correct answer is 27.5 feet
Step-by-step explanation:
The scale of a blueprint is a ratio that represents the relationship between the size of an object on the blueprint and the size of the actual object. In this case, the scale is 1:55, which means that for every 1 unit of length on the blueprint, the actual object is 55 units long.
If a wall on the blueprint is 6 inches long, then the actual wall is 55 times longer, or 6 inches * 55 = 330 inches. Since there are 12 inches in a foot, the actual wall is 330 inches / 12 inches/foot = 27.5 feet long. Therefore, the correct answer is 27.5 feet

105 oranges, 126 apples, and 147 pears are equally packed in fruit boxes so that no fruit is left. What is the largest possible number of fruit boxes needed?
Answers
Answer:
the LCM of 105, 126, and 147 is 18420.
Since the fruit boxes need to be equally packed and no fruit is left, the largest possible number of fruit boxes needed is 18420/105 = 176 fruit boxes.
Step-by-step explanation:
To find the largest number of fruit boxes needed, we need to find the least common multiple (LCM) of 105, 126, and 147.
What is the least common multiple (LCM)?[The least common multiple is the smallest number that is a multiple of all the given numbers. One way to find the LCM of three numbers is to first find the LCM of two of the numbers, and then find the LCM of the result with the third number.]
To find the LCM of 105 and 126, we can list the multiples of each number and look for the smallest number that is a multiple of both:
Multiples of 105: 105, 210, 315, 420, 525, 630, 735, 840, 945, 1050, 1155, 1260, ...
Multiples of 126: 126, 252, 378, 504, 630, 756, 882, 1008, 1134, 1260, 1386, 1512, ...
The smallest multiple that both 105 and 126 share is 1260. Therefore, the LCM of 105 and 126 is 1260.
Now we can find the LCM of 1260 and 147 by finding the smallest multiple of 1260 that is also a multiple of 147:
Multiples of 1260: 1260, 2520, 3780, 5040, 6300, 7560, 8820, 10080, 11340, 12600, 13860, 15120, ...
Multiples of 147: 147, 294, 441, 588, 735, 882, 1029, 1176, 1323, 1470, 1617, 1764, ...
The smallest multiple that both 1260 and 147 share is 18420. Therefore, the LCM of 105, 126, and 147 is 18420.
Since the fruit boxes need to be equally packed and no fruit is left, the largest possible number of fruit boxes needed is 18420/105 = 176 fruit boxes.
What is the slope of a line perpendicular to the line whose equation is 4 x + 10 y = -140
Answers
Answer:
5/2
Step-by-step explanation:
Perpendicular lines are opposite reciprocals:
For example, -2 and 1/2 are opposite reciprocals:
Negate 1/2 to get -1/2. Then take the reciprocal of -1/2 to get -2.
In order to find the slope of an equation, isolate y:
4x + 10y = -140 ==> solve for y
10y = -4x - 140 ==> subtract 4x on both sides
y = (-4x - 140)/10 ==> divide both sides by 10 to isolate y
y = -4x/10 - 140/10 ==> divide each term by 10
y = -2x/5 - 14 ==> simplify
^^ In this equation, the slope is -2/5 since y increases by -2/5 every time x increases by 1.
Now take the opposite reciprocal of -2/5:
First, take the reciprocal of -2/5 by switching the numerator and denominator: -2/5 ==> -5/2
Now negate the result: -5/2 ==> -(-5/2) = 5/2
Hence, 5/2 is the slope of the line perpendicular to 4x + 10y = -140

The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Given, A cone, cylinder, and Sphere all have the same radius with the height of the cone and cylinder being twice the radius.
The volume of the cone = [tex]\frac{1}{3}[/tex] πr²h
Since, h = 2r
The volume of the cone = [tex]\frac{1}{3}[/tex] πr² * 2r = 2/3 πr³
The volume of the Cylinder = πr²h
Since, h = 2r
The volume of the Cylinder = πr² * 2r = 2πr³
The volume of the sphere = 4 πr³
Thus, the volume of 3 cones = 2πr³
that is also equal to The volume of one Cylinder.
Thus, the volume of 2 cones = 4/3πr³
that is also equal to The 1/3 volume of the Cylinder.
Thus, the volume of 1 sphere = 4πr³

What is a dilation?A dilation happens when the coordinates of the vertices of an image are multiplied by the scale factor, changing the side lengths of a figure.
For the dilation, due to the multiplication of the side lengths by the scale factor, the side lengths are modified, meaning that the original triangle and the dilated triangle are not congruent.
The angle measures, conversely, remain constant, meaning that the original triangle and the dilated triangle are similar.
As the two circles in this problem are similar, we have that the central angle has the same measure.

k = 2.5/5 = 0.5.
Then the length of arc EF is given as follows:
EF = 0.5 x 8.84 = 4.42.
