All the roles have now been cast, and the lead actors playing the following parts are gathered around a large circular table for their first read: Jean Valjean, Inspector Javert, Thénardier, Enjolras, Marius, Fantine, adult Cosette, adult Éponine, and Madame Thénardier. It is your job to seat these 9 actors, the 3 producers, and the director around the table.
In Les Misérables, Monsieur Thénardier and Madame Thénardier are married, and during Act 2, Cosette and Marius become married. If the Thénardiers must next to one another, and Cosette and Marius must sit next to one another, but there are no restrictions on how the others can sit, how many different ways can you seat the 13 people around the circular table?

Suppose you are a new employee. You notice that each payment option describes a sequence and decide to use rules to help determine which option to take.
Determine the iterative rule for each sequence. Show your work.
Your friend trusts your tables in Problem 1, but wonders if you wrote the iterative rules correctly. Show two calculations to convince your friend that both your rules work.
my table is below (it is correct, I checked with my math teacher, it is ten percent added to the previous week for all you doubters)
The iterative rule for each sequence in the table will be to use the slope-intercept form of the equation of a line y=mx+b.
How to depict the information?In this situation, x is the week, and y is the amount paid. Basically, you need to find the slope, represented by m, which is the amount the amount paid increases by each week, and the y-intercept, b, which is the "amount paid" at week 0.
The x-coordinate is the week, and the y coordinate is the amount paid. Because the weeks are incrementing by 1, x2-x1=1.
After that, to complete the rule, you need to find the y-intercept. If the amount paid is 200 on week 1, and the amount paid increases by 50 each week.
Another way to think about it is by plugging your points into the incomplete rule. Let b represent the y-intercept. Plug in the values for week 1 and solve for b.
The calculations to convince your friend that both your rules work are:
m=(y2-y1)/(x2-x1)
(x1,y1)=(1,200)
(x2,y2)=(2,250)
m=(250-200)/(2-1)
=50/1 =50

Often times you can use similar triangles in the real world. Sarah is attempting to find the height of a tree by using a mirror. By the laws of physics she knows that the angle of incidence is congruent to the angle of reflection (these are marked in red on the diagram). Explain why the two triangles are similar and if she knows her height and the distance from the mirror to her feet and also the distance from the mirror to the tree how could she calculate the height of the tree?
The two triangles are similar by the AA Similarity theorem.
The height of the tree can be calculated by figuring out the ratio between the distance between the mirror to her feet and the distance from the mirror to the tree
How to use the concept of similar Triangles?From Law of Reflection, we know that the angle of incidence and the angle of reflection are equal to each other.
Now, triangles can be proved similar by the AA, SAS, or SSS theorems. However, in this question, the triangles as seen in the attached image can be proved similar by the AA similarity theorem.
This is because both triangles have one congruent angle in common.
Sarah and the tree are standing straight and perpendicular to the ground and as such, the angles formed by Sarah and the tree are right angles.
The above tells us that the two triangles have two angles in common, making them similar triangles by the AA (Angle Angle) similarity theorem.
Since the triangles are similar, it means that the ratios of the sides of the triangles will be the same. Thus, if Sarah knows the distance from the mirror to her feet and the distance from the mirror to the tree, she can create the ratio between the two triangles.

Find the equation for the line that passes through the point (2, -3), and that is parallel to the line with the equation x - 3y = 3
Step-by-step explanation:
the slope of a line is the factor of x, when the equating looks like
y = ...
so,
x - 3y = 3
x = 3y + 3
3y = x - 3
y = 1/3 x - 1
so, the original slope is 1/3.
a parallel line has the same slope.
having a specific point we can use the point-slope form as equation :
y - y1 = m(x - x1)
with m being the slope, and (x1, y1) being a point on the line.
y - -3 = 1/3(x - 2)
y + 3 = 1/3(x - 2)
simplified that is
y + 3 = 1/3 x - 2/3
y = 1/3 x - 2/3 - 3 = 1/3 x - 2/3 - 9/3 = 1/3 x - 11/3 =
= 1/3 × (x - 11)
Answer:
[tex]y=\frac{1}{3}x - \frac{11}{3}[/tex]
Step-by-step explanation:
We are given the line x-3y=3.
We want to write the equation of the line that is parallel to this line, and that passes through (2, -3).
Parallel lines have the same slope.
Therefore, let's find the slope of x-3y=3.
The line is currently written in standard form, which is ax+by=c, where a, b, and c are free integer coefficients.
In order to find the slope of this line, we can convert it into slope-intercept form, which is y=mx+b, where m is the slope and b is the value of y at the y intercept.
To do that, we need to isolate y on one side; this is the same as solving the equation for y.
x - 3y = 3
Start by subtracting x from both sides
-3y = -x + 3
Now divide both sides by -3
[tex]y = \frac{1}{3} x - 1[/tex]
The slope of the line is 1/3, as 1/3 is the coefficient in front of x.
It is also the slope of our new line.
Since the question doesn't specify which format for the equation of the line, we can use any form. However, let's put the equation of the new line into slope-intercept form.
So, substitute 1/3 as m in y=mx+b.
[tex]y = \frac{1}{3} x + b[/tex]
Now we need to find b.
As the equation passes through the point (2, -3), we can use its values to help solve for b.
Substitute 2 as x and -3 as y.
[tex]-3 = \frac{1}{3} (2) + b[/tex]
Multiply.
[tex]-3 = \frac{2}{3} + b[/tex]
Subtract 2/3 from both sides (we can write this as an improper fraction).
[tex]-\frac{11}{3} = b[/tex]
Substitute -11/3 as b in the equation.
[tex]y=\frac{1}{3}x - \frac{11}{3}[/tex]

We will spend altogether $1400.
We know that the process of combining two or more items is known as an addition. Addends are the sums of the numbers that are added. The addition sign (+), which is positioned in between the addends, is present. The outcome of adding the addends is referred to as the sum.
Given that
Food = $594.09
Clothes = $204.33
Trips = $100.40
Transport = $310.05
Extras = $189.74
Now we have to round each price to a hundred dollars.
Food = $600
Clothes = $200
Trips = $100
Transport = $300
Extras = $200
Now the sum = 600 + 200 + 100 + 300 + 200 = 1400
Therefore, we will spend altogether $1400.
