The value of the set (A∪C)'∩B is {9 , 12} .
A subfield of mathematical logic called set theory examines sets, which are essentially collections of objects.
Set theory is a discipline of mathematics that largely addresses problems that are pertinent to mathematics as a whole, despite the fact that any kind of object can be constructed into a set.Set theory is founded on a simple binary relationship between an object o and a set A.It is written as o A if o is a part (or member) of A. Members of a set are enumerated with commas to denote separation when describing them, or a property of those parts is enclosed in braces.Sets can be associated by the membership relation since they are objects.The given sets are:
U ={1,2,3,4,5,6,7,8,9,10,11,12,13}
A = {3,7,11,13}
B = {3,6,9,12,13}
C = {2,3,5,6,7,8}
Now B' = {1,2,4,5,7,8,10,11}
b) B'∩C = {2,5,7,8,}
c) A∪C = {2,3,5,6,7,8,11,13}
(A∪C)' = {1,4,9,10,12}
(A∪C)'∩B = {9 , 12}
Hence the value of the set (A∪C)'∩B is {9 , 12} .

Two trains for Palwal leave Kanpur at 10 am and 10:30 am and travel at the speeds of 60Kmph and 75Kmph respectively. After how many kilometers from Kanpur will the two trains be together?
Answers
Answer:
150 km
Step-by-step explanation:
You want to know the number of kilometers each train has traveled when they meet. The first goes 60 km/h and has a half-hour head start. The second goes 75 km/h.
SetupAt t hours after 10 am, the distance of the first train from Kanpur will be ...
distance = speed × time
distance = 60t
At t hours after 10 am, the distance of the second train from Kanpur will be ...
distance = 75(t -1/2) . . . . . . the distance is 0 at 10:30 am, 1/2 after 10 am
These distances will be equal when ...
60t = 75(t -1/2)
SolutionThe time at which the trains meet will be the solution to the above equation.
60t = 75t -37.5 . . . . eliminate parentheses
0 = 15t -37.5 . . . . . . subtract 60t
0 = t -2.5 . . . . . . . . . divide by 15
2.5 = t . . . . . . . . . the trains meet 2.5 hours after the first one leaves
The distance traveled by each of the trains is the same at that time. It will be the distance traveled by the first train:
60t = 60(2.5) = 150 . . . . km
The two trains will be together 150 km from Kanpur.

To find:
The changes to the surface area of a sphere
Explanation:
Let us take the original radius as r.
The surface area of the original sphere is,
[tex]A=4\pi r^2[/tex]a) The new radius will be,
[tex]R=2r[/tex]So, the surface area of the sphere with the new radius is,
[tex]\begin{gathered} A=4\pi R^2 \\ =4\pi(2r)^2 \\ =4\pi(4r^2) \\ A=4(4\pi r^2) \\ A=4\times Surface\text{ area of old sphere} \end{gathered}[/tex]Therefore, the surface area of a sphere becomes four times the original surface area if the radius is doubled.
b) The new radius will be,
[tex]R=3r[/tex]So, the surface area of the sphere with the new radius is,
[tex]\begin{gathered} A=4\pi R^2 \\ =4\pi(3r)^2 \\ =4\pi(9r^2) \\ A=9(4\pi r^2) \\ A=9\times Surface\text{ area of old sphere} \end{gathered}[/tex]Therefore, the surface area of a sphere becomes nine times the original surface area if the radius is tripled.

The linear equation that passes through the two points (0, 360) and (10, 560) is:
y = 20*x + 360
How to find the linear equation?Remember that the slope-intercept form of a linear equation is:
y = a*x + b
Where b is the y-intercept and a is the slope or rate of change.
If we know that the line passes through the points (x₁, y₁) and (x₂, y₂) then the slope is:
[tex]a = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
Here the line must pass through (0, 360) and (10, 560), so the slope is:
[tex]a = \frac{560 - 360}{10 - 0} = 20[/tex]
And because of the point (0, 360) we can see that the y-intercept is 360, then the linear equation is:

Answers
Alice plans to buy a house. She has $2,000 in her savings account.
She plans to contribute $150 to the account each month.
We know that with each month, n, she deposits $150 and so, each month, her savings account balance increases by $150.
This simply means that after n months, her savings account balance would have increased by:
150 * n = 150n
Her initial balance was $2000, therefore, her balance after n months will be the sum of 150n and the amount that was initially there.
That is:
f(n) = 2000 + 150n
This is the function that describes the relationship between the number of months and her balance.

The equation of the line through pair of points (0,1) and (3,0)
⇒ y - y₁ = [(y₂ - y₁)/(x₂ -x₁ )](x - x₁ )
Here x₁ = 0 and y₁ = 1
x₂ = 3 and y₂ = 0
The equation of the line is obtained by substituting these values into the above equation;
⇒ y - 1 = [(0-1)/(3-0)](x -0)
⇒ y - 1 = (-1/3)x
⇒ 3y - 3 = x
⇒ 3y + x = 3
The equation of the line through pair of points (1/2,2/3) and (-3/2,5/3)
⇒ y - 2/3 = [(5/3 -2/3)/(-3/2-1/2)](x -1/2)
⇒ y - 2/3 = [(3/3)/(-4/2)](x -1/2)
⇒ y - 2/3 = (1/3)(x -1/2)
Multiply by 6 both sides of the equation,
⇒ 6y - 4 = 2(x -1/2)
⇒ 6y = 2x -1 + 4
⇒ 6y = 2x +3
The equation of the line through pair of points (-3,-2) and (1,6)
⇒ y - (-2) = [(6-(-2))/(1-(-3))](x -(-3))

b. Find the domain of the function. Is the domain

c. Graph the function using its domain.
Answers
Considering the given linear function, it is found that:
a)
The intercept is of 10, meaning that initially you have $10.The slope is of -1.44, meaning that the cost of printing each photo is of 1.44.b) The discrete domain of the function is: {0, 1, 2, 3, 4, 5, 6, 7}.
c) The graph of the function is given at the end of the answer.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the rule given below:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the y-axis(x = 0).The amount of money you have remaining after printing p photographs is modeled by the following function:
M(p) = 10 - 1.44p.
Hence the coefficients are as follows:
The intercept is of b = 10, meaning that initially you have $10 to spend on printing photos.The slope is of -1.44, meaning that the cost of printing each photo is of 1.44, that is, for each photo you print, you are going to lose $1.44 from your amount.The number of photos printed is a discrete number, as this number cannot assume decimal values, hence the domain is also discrete.
You cannot print a negative value of numbers, neither can M(p) be negative, hence the domain, which is the number of photos you can print, is:
{0, 1, 2, 3, 4, 5, 6, 7}.
Considering the above domain, the graph of the function is given by the image at the end of the answer.

Probability:
Probability refers the measure of the likelihood of an event to occur.
The formula of Probability is
Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes
Given,
Suppose that your boss must choose three employees in your office to attend a conference in Jamaica. Because all 28 of you want to go, he decides that the only fair way is to draw names out of a hat.
Here we need to find the probability that you, Shirley, and Matthew are chosen.
Here we have assuming that the selection process is fair;
We know that, the total number of employees is 28
Therefore, the probability of selecting each employee is,
=> 1/28
So, the probability of selecting yourself, Shirley, and Matthew is calculated as,
=> 1/28 x 1/27 x 1/26
=> 1/19656
=> 0.00005
When we round off it into four decimal place then we get,
