Answer
\((f\text{ o g)(x) = }\frac{3x-16}{17-3x}\)Explanation
We are given that
f(x) = (2 - x)/(x + 1)
g(x) = 18 - 3x
We are then asked to find (f o g)(x)
(f o g) (x) is the same as writing the expression for f(x) but instead of x, we will write g(x) in the expression.
\(\begin{gathered} f(x)=\frac{2-x}{x+1} \\ (\text{fog)(x) = }\frac{2-g(x)}{g(x)+1} \end{gathered}\)Recall that
g(x) = 18 - 3x
So,
\(\begin{gathered} (\text{fog)(x) = }\frac{2-g(x)}{g(x)+1} \\ (\text{f o g)(x) = }\frac{2-(18-3x)}{18-3x+1} \\ (f\text{ o g)(x) = }\frac{2-18+3x}{17-3x} \\ (f\text{ o g)(x) = }\frac{-16+3x}{17-3x} \\ (f\text{ o g)(x) = }\frac{3x-16}{17-3x} \end{gathered}\)Hope this Helps!!!
4 children each have some beads, the mean number of beads is 8 Rajiv brings some more beads. The mean number of 5 children is now 9 what is the numberx of beads Rajiv brings
Answer:
The number of beads Rajiv brings is: 13Step-by-step explanation:
Make a plan:In this question, we need to use the formula of means to solve the. We can set the number of beads Rajiv brings as X, and use the formula of mean to get the total number of beads that the Four(4) children have and the total number of beads that the Five(5) children have.
Solve the problem:Four(4) children each have some beads, the mean number of beads is: 8
We can get the total number of beads the Four(4) children have:4 * 8 = 32
Rajiv brings some more beads:We set the number of beads Rajiv brings as:
x, so the total number of beads that the Five(5) children have is:
32 + x
The mean number of the Five(5) children is now: 9
We can get the total number of beads that the Five(5) children have:5 * 9 = 45
Now, we have the equation:32 + x = 45
x + 32 = 45
- 32 = -32
x = 13
By solving the above equation, you can get:
x = 13
Hence, The number of beads Rajiv brings is:13
Hope this helps!
Hi can any one teach me this constant difference
The constant differences between the consecutive terms are 2 (a); 2 (b), -3 (c), 7 (d), 1(e), and 6(f).
How do you find the constant difference in a sequence of numbers?In math, the constant difference can be defined as the number that defines the pattern of a sequence of numbers. This means that number that should be added or subtracted to continue with the sequence.
Due to this, to determine the constant difference it is important to observe the pattern and find out the number that should be added. For example, if the sequence is 2, 4, 6, 8, there is a difference of 2 between each of the numbers and this is the constant difference.

Name the rotation that maps the black triangle onto the red triangle. Explain how you know(See picture below)
We would compare the coordinates of corresponding vertices on the red and black triangles. The vertex at the top of the black triangle and the vertex at the bottom of the red triangle correspond to each other. We would compare them.
For black triangle, coordinate is (1, - 3)
For red triangle, coordinate is (- 1, 3)
If a vertex with coordinate, (x, y) is rotated 180 degrees counterclockwise about the origin, the new coordinate is (- x, - y). By rotating (1, - 3) 180 degrees counterclockwise, it becomes (- 1, - - 3) = (- 1, 3). This corresponds to the coordinate of the corresponding vertex of the red triangle. Thus, the rotation that maps the black triangle onto the red triangle is 180 degrees counterclockwise rotation about the origin

How can u find a geometry-big circle mAB=56 mBC=59 mCD=63 mDE=63 mEF= 31
To find the measure of the geometry-big circle, we need to sum up the measures of all the arcs around the circle.
We are given the following measures:
\(\sf\:m\angle AB = 56 \\\)
\(\sf\:m\angle BC = 59 \\\)
\(\sf\:m\angle CD = 63 \\\)
\(\sf\:m\angle DE = 63 \\\)
\(\sf\:m\angle EF = 31 \\\)
To find the measure of the geometry-big circle, we add up these measures:
\(\sf\:m\angle AB + m\angle BC + m\angle CD + m\angle DE + m\angle EF \\\)
Substituting the given values:
\(\sf\:56 + 59 + 63 + 63 + 31 \\\)
Simplifying the expression:
\(\sf\:272 \\\)
Therefore, the measure of the geometry-big circle is 272.

A student rolls a number cube 40 times. He rolls a 3 on the number cube 6 times. What is the experimental probability that he rolls a 3?
Answer:
\(\frac{6}{40}=\frac{3}{20}\)
Step-by-step explanation:
The experimental probability is the number of times the desired result was obtained over the total number of times the experiment was carried out:
\(P=\frac{TimesTheEventOccurs}{TotalNumberOfTrials}\)
In this case the Event we are looking for is rolling a 3 on the number cube.
The total number of trials is:
40
because the student rolls the cube 40 times.
and the times that he got the number 3 (the times the desired event occurs) is:
6
because he rolls a 3 on the number cube 6 times.
Thus our experimental probability to roll a 3 is:
\(P=\frac{6}{40}\)

Why does marginal cost curve cut average cost curve only at its minimum point?
The marginal cost of producing the next unit of output always affects the average total cost, so the marginal cost curve always intersects the average total cost curve at its lowest point.
The difference in overall production costs caused by creating or producing one more unit is known as the marginal cost.
By producing at the point where marginal cost (MC) equals marginal revenue, a business can optimize its earnings (MR).
Because fixed costs are fixed regardless of output levels, larger production spreads the total fixed cost over more units, resulting in a lower fixed cost per unit.
Production levels affect variable costs, so increasing the number of units will increase those costs.
Companies need to be aware of the situations when expanding production entails step costs as a result of shifting relevant ranges.

Write 4-6 sentences describing how you can use the form of a quadratic equation to decide how it can most efficiently be solved. For each solution method (factoring, by inspection, taking a square root, completing the square, and the quadratic formula), formulate an equation that would be the most efficiently solved using that approach. Write a comprehensive solution process for each as though you are explaining it to a friend who is struggling with this topic.
I do not need 4-6 sentences, but just need main points so I can form my own sentences.
Answer:
See explanation
Step-by-step explanation:
The place to begin in attempting to solve a quadratic equation is to try to factorize it. If it can not be factorized, then look at the side of equation that contains the variable (x,b,m,n and so on). If that side is a perfect square, try to take square root of both sides.
Also, if the coefficient of the squared term in the equation is 1 and the coefficient of the middle term bearing the variable is an even number, then you can attempt to use completing the square method. Formula method can be adopted as a last resort.
x^2 -4x + 4 =0 can be solved by factorization
X(x-2) - 2(x-2) =0
Hence;
(x-2) (x-2) =0
x= 2 (twice)
(2x-2)^2 = 4 can be solved by taking square root
√[(2x-2)^2] = √4
2x-2 = 2
x= ±2
x^2 + 6x - 11 = 0 can be solved by completing the square
(x + 3)^2 = 11 + 3^2
(x + 3)^2 = 20 taking square root of both sides
x + 3 = ±√20
x + 3 = ±2√5
x= -3 ±2√5
2x^2 - x + 5 = 0 can be solved by formula method
Using
x= -b±√b^2 - 4ac/2a
a= 2, b = -1, c= 5
x= 1 ± √1 - 40/4
x= 1 ± √-39/4
x= 1 ± 39i/4

A Man bought a goat at 60k
He sold it at 70k
He bought it again at 80k
Later sold it at 90k. How much profit did he make
Answer:
20,000
Step-by-step explanation:
To calculate the profit made by the man, we need to find the difference between the total selling price and the total buying price.
Given:
First buying price = 60,000
First selling price = 70,000
Second buying price = 80,000
Second selling price = 90,000
First transaction profit:
Profit = First selling price - First buying price
Profit = 70,000 - 60,000
Profit = 10,000
Second transaction profit:
Profit = Second selling price - Second buying price
Profit = 90,000 - 80,000
Profit = 10,000
To find the total profit, we add the profit from each transaction:
Total profit = Profit from first transaction + Profit from second transaction
Total profit = 10,000 + 10,000
Total profit = 20,000
Therefore, the man made a profit of 20,000.
what is: a + 1/10=5/10 ? pls dont delete this its school work.
Answer:
a = 2/5
Step-by-step explanation:
a + 1/10 = 5/10
Subtract 1/10 from both sides of the equation.
a + 1/10 = 5/10
-1/10 -1/10
a = 4/10
This answer is not incorrect but we usually need to simplify it if possible.
4/10 can be reduced to 2/5.
a = 2/5
Answer:
a=2/5
Step-by-step explanation:
To solve this, we first need to isolate the a so we can solve from there
First, we subtract 1/10. But whatever we do to one side we have to do to the other side. So when we subtract 1/10 from the left side we cancel it out and we subtract 1/10 from the right side so 5/10-1/10
So our equation becomes…
a=5/10-1/10
We can simplify this to…
a=4/10
4/10 is equal to 2/5
So that is our final answer
Now since we have nothing else to do that is our final answer

eled y with entries negative 26, negative 14, 34, 46.
The linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.
To determine the linear function with the same y-intercept as the graph, we need to find the equation of the line passing through the points (3, 4) and (5, 0).
First, let's find the slope of the line using the formula:
slope (m) = (change in y) / (change in x)
m = (0 - 4) / (5 - 3)
m = -4 / 2
m = -2
Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:
y - y1 = m(x - x1)
Using the point (3, 4) as our reference point, we have:
y - 4 = -2(x - 3)
Expanding the equation:
y - 4 = -2x + 6
Simplifying:
y = -2x + 10
Now, let's check the given options to find the linear function with the same y-intercept:
Option 1: The table with x-values (-3, -1, 1, 3) and y-values (-4, 2, 8, 14)
The y-intercept is not the same as the given line. So, this option is not correct.
Option 2: The table with x-values (-4, -2, 2, 4) and y-values (-26, -18, -2, 6)
The y-intercept is not the same as the given line. So, this option is not correct.
Option 3: The table with x-values (-5, -3, 3, 5) and y-values (-15, -11, 1, 5)
The y-intercept is the same as the given line (10). So, this option is correct.
Option 4: The table with x-values (-6, -4, 4, 6) and y-values (-26, -14, 34, 46)
The y-intercept is not the same as the given line. So, this option is not correct.
Therefore, the linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

What is Percentage?
To compute a percentage, divide the value by the entire amount and multiply the result by 100. A percentage is a quantity or ratio that is stated as a fraction of one hundred. The percent sign, "%," is frequently used to represent it.
First, we need to calculate the average of Maureen's three highest salaries:
Average = (107,000 + 107,800 + 108,198) / 3
Average = 322,998 / 3
Average = 107,666
Next, we need to calculate 1.56% of this average:
Percentage = 1.56% * 107,666
Percentage = 1,667.84
Finally, we multiply this percentage by the number of years worked to find the pension:

Question Which is closest to the surface area of the figure below? 1463.8 m squared 578.1 m squared 923.2 m squared 3692.6 m2
The closest option to the cone area is 923.2 m².
What is a cone?A cone is a shape formed from a series of line segments or lines that connect a common point, called a vertex or vertex, to all points on the base of a circle that do not contain vertices. The distance from the apex of the cone to the base is called the height of the cone.
To solve this problem, we need to find the surface of the cone. Formula for the surface area of cone:
A = \(\pi\)r² + \(\pi\)rℓ
where r is the radius of the base, ℓ is the height of the depression, and π is a constant of approximately 3.14159.
First, we find the radius of the base. Since the bottom line of the cone is listed as 18 feet and we know the radius is 14 feet, we can use the Pythagorean theorem to find the height of the cone.
h² = ℓ² - r²
h² = 19.3² - 14²
h ≈ 11.48 feet
Now we can compute the surface.
A = \(\pi\)(14)² + \(\pi\)(14)(19.3)
A ≈ 923.2 square feet
So the closest option to the cone area is 923.2 m².
