Prove: 36 + 324 + 900+. . . +(12n − 6)2 = 12n(4n2 − 1)
By mathematical induction, the given formula holds for all natural numbers n:
S(n) = 36 + 324 + 900 + ... + (12n - 6)² = 12n(4n² - 1)
How to solveTo demonstrate our point, mathematical induction can be employed.
We want to prove that the given formula holds for all natural numbers n:
S(n) = 36 + 324 + 900 + ... + (12n - 6)² = 12n(4n² - 1)
Using mathematical induction:
Step 1: Base case (n=1)
S(1) = 6² = 36
12 * 1 * (4 * 1² - 1) = 36
Since S(1) holds true, the base case is proven.
Step 2: Inductive step (Assume it's true for n=k, and show it's true for n=k+1)
Assumption: S(k) = 36 + 324 + 900 + ... + (12k - 6)² = 12k(4k² - 1)
We follow the exhaustive process to prove:
= 12(4k³ + 12k² + 11k + 3)
Since both expressions for S(k+1) are equal, the inductive step is proven.
Thus, by mathematical induction, the given formula holds for all natural numbers n:
S(n) = 36 + 324 + 900 + ... + (12n - 6)² = 12n(4n² - 1)

Write an equation then find the value of y when x =16. Show all work.
Answer:
Answer is A
Step-by-step explanation:
A) y = -1/2x represents a proportional relationship because the equation can be written in the form y = kx, where k is a constant. In this case, k = -1/2, which means that y is proportional to x with a constant of proportionality of -1/2.
B) y = 2x - 4 does not represent a proportional relationship because the equation cannot be written in the form y = kx. If we try to write it in this form, we get y/x = 2 - 4/x, which means that y/x is not constant. Therefore, y is not proportional to x with a constant of proportionality.
Carleigh, Inc., is a pork processor. Its plants, located in the Midwest, produce several products from a common process: sirloin roasts, chops, spare ribs, and the residual. The roasts, chops, and spare ribs are packaged, branded, and sold to supermarkets. The residual consists of organ meats and leftover pieces that are sold to sausage and hot dog processors. The joint costs for a typical week are as follows: Direct materials $84,500 Direct labor 29,000 Overhead 20,000 The revenues from each product are as follows: sirloin roasts, $68,000; chops, $71,000; spare ribs, $33,000; and residual, $9,800. Carleigh’s management has learned that certain organ meats are a prized delicacy in Asia. They are considering separating those from the residual and selling them abroad for $52,000. This would bring the value of the residual down to $2,650. In addition, the organ meats would need to be packaged and then air freighted to Asia. Further processing cost per week is estimated to be $27,500 (the cost of renting additional packaging equipment, purchasing materials, and hiring additional direct labor). Transportation cost would be $12,100 per week. Finally, resource spending would need to be expanded for other activities as well (purchasing, receiving, and internal shipping). The increase in resource spending for these activities is estimated to be $3,120 per week.
Carleigh, Inc. should separate the organ meats from the residual and sell them abroad, as it would increase their total revenue by $17,150 per week.
To determine whether Carleigh, Inc. should separate the organ meats and sell them abroad, we need to calculate the incremental revenue and incremental costs associated with this decision.
The incremental revenue would be the revenue generated from selling the organ meats abroad, which is $52,000 per week. The incremental cost would include the cost of further processing ($27,500 per week), transportation cost ($12,100 per week), and the increase in resource spending for other activities ($3,120 per week).
Therefore, the incremental cost would be $42,720 per week. Subtracting this from the incremental revenue of $52,000, we get an incremental profit of $9,280 per week.
However, this decision would also decrease the value of the residual from $9,800 to $2,650 per week. Therefore, we need to subtract this decrease in value from the incremental profit. This gives us a net increase in profit of $17,150 per week ($9,280 - $7,130).
Thus, it would be beneficial for Carleigh, Inc. to separate the organ meats and sell them abroad.

19. Two angles are complementary. The larger
angle is 36 more than the smaller angle. What
is the measure of the larger angle?
Answer:
larger angle = 63°
Step-by-step explanation:
complementary angles sum to 90°
let x be the smaller angle then larger angle is x + 36 , then
x + x + 36 = 90
2x + 36 = 90 ( subtract 36 from both sides )
2x = 54 ( divide both sides by 2 )
x = 27
Then
larger angle = x + 36 = 27 + 36 = 63°

A construction company is planning to bid on a building contract. The bid costs the company $1100. The probability that the bid is accepted is 1/10
. If the bid is accepted, the company will make $96,000 minus the cost of the bid.
What is the expected value in this situation?
Choose the statement below that best describes what this value means.
A.
In the long run, the construction company would expect to earn this amount on average per bid.
B.
In the long run, the construction company would expect to break even on average.
C.
In the long run, the construction company would expect to lose this amount on average per bid.
D.
None of the above
Answer:
The expected value in this situation can be calculated as follows:
E(X) = P(X) * V(X), where X is the random variable representing the profit of the construction company, P(X) is the probability of X, and V(X) is the value of X.
In this case, the profit of the construction company if the bid is accepted is $96,000 - $1,100 = $94,900, and the probability of the bid being accepted is 1/10. Therefore, we have:
E(X) = (1/10) * $94,900 = $9,490
The expected value of $9,490 means that in the long run, the construction company would expect to earn this amount on average per bid. Therefore, the correct answer is option A: "In the long run, the construction company would expect to earn this amount on average per bid."
Write an explicit formula that represents the sequence defined by the following recursive formula:
The explicit formula for the sequence defined by the recursive formula a₁ = 150 and aₙ = -1/5 aₙ₋₁ is aₙ = 150 [tex](-1/5)^{(n-1)[/tex].
To find the explicit formula that represents the sequence defined by the given recursive formula, we need to find a pattern in the sequence and express it using a formula.
The first term in the sequence is a₁ = 150. To find the second term, we use the recursive formula: a₂ = -1/5 a₁ = -1/5(150) = -30. To find the third term, we use the recursive formula again: a₃ = -1/5 a₂ = -1/5(-30) = 6.
We can continue this process to find the fourth term: a₄ = -1/5 a₃ = -1/5(6) = -6/5, and so on.
By observing the pattern, we notice that each term is obtained by multiplying the previous term by -1/5. Therefore, the explicit formula for the sequence can be written as:
aₙ = 150 [tex](-1/5)^{(n-1)[/tex]
This formula gives the value of any term in the sequence based on its position n. It can be used to find any term in the sequence without having to recursively calculate all the previous terms.

C $200,000
D $167,000
E $2,500,000
Based on the data, should Jasper use the mean or the median to make an inference about the house values in his neighborhood? (10 points)
Group of answer choices
He should use the mean because it is in the center of the data.
He should use the median because it is in the center of the data.
He should use the median because there is an outlier that affects the mean.
He should use the mean because there are no outliers that affect the mean.
Answer:
Jasper should use the median to make an inference about the house values in his neighborhood because there is an outlier that affects the mean. The outlier in this case is the house with a value of $2,500,000, which is significantly higher than the other house values in the sample. The mean is sensitive to outliers, which means that the outlier can significantly affect the value of the mean. In contrast, the median is not affected by outliers, which makes it a better measure of central tendency for this data set. Therefore, Jasper should use the median because it is in the center of the data and is not affected by the outlier. Answer: He should use the median because there is an outlier that affects the mean.
Answer:
The answer to your problem is, C. He should use the median because there is an outlier that affects the mean. &; A & E $150,000 ‘n’ $200,000
Step-by-step explanation:
The outlier is represented as ‘ E ‘ the highest price value and lowest between, $150,000 to $200,000.
But since ‘ E ‘ is represented highest it is an outlier making ‘ E ;
$150,000 ‘n’ $200,000
So ‘ E ‘ is represented as, $150,000 ‘n’ $200,000
The second option for ‘ 10 points ‘ is He should use the median because there is an outlier that affects the mean, being the ‘ Option C ‘
Thus the answer to your problem is, C. He should use the median because there is an outlier that affects the mean. &; A & E $150,000 ‘n’ $200,000

Point A is located at (1, 2). Point B is located at (4, 6). Use this information to determine the length of the line, rounded to the nearest whole number.
If Point A is located at (1, 2) and Point B is located at (4, 6), the length of the line between points A and B is 5 units.
To determine the length of the line between points A and B, we can use the distance formula, which is a formula used to calculate the distance between two points in a coordinate plane. The distance formula is:
d = √((x₂ - x₁)² + (y₂ - y₁)²)
where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points and d is the distance between them.
Using the coordinates of points A and B, we can substitute their values into the distance formula to find the length of the line between them:
d = √((4 - 1)² + (6 - 2)²)
d = √(3² + 4²)
d = √(9 + 16)
d = √25
d = 5
Rounded to the nearest whole number, the length of the line is also 5 units.
In conclusion, we can use the distance formula to find the length of the line between two points in a coordinate plane. The distance formula uses the coordinates of the two points to calculate the distance between them. The resulting distance can be rounded to the nearest whole number, if needed.

A proportional relationship is a relationship between two variables where the ratio of their values is constant. This means that if we multiply one of the values by a constant, the other value also gets multiplied by the same constant.
The graph of a proportional relationship is a straight line that passes through the origin. This is because the ratio of the x- and y-values is constant, so the points can be plotted as a straight line.
The ordered pairs all have the same x- and y-values means that the two variables are perfectly correlated. This is not necessary for a proportional relationship, but it is a common characteristic.
The line connecting the points does not need to pass through the origin for the relationship to be proportional. However, if the line does pass through the origin, then the two variables are directly proportional. Option B and D are the correct answer.

it took people a very long time to Real like that zero is an important number. why do you think that people found difficult to accept zero as a number
Answer:
I think that people found difficult to accept zero as a number because people think that zero doesn't have any value. In a way yes Zero doesn't have value but zero is also a very important number because sometimes we need to solve some questions and we need to add value but if we need to add that particular value we should even subtract that value which makes it zero. So I think the reason is people don't think zero has any value. But in my point if view zero has many values.

If the gross amount is USD 365, what is the net amount after adding 20%?
USD 438
Step-by-step explanation:If we add 20% to the gross amount of USD 365, the total amount would be:USD 365 + 20% of USD 365 = USD 365 + (0.20 * USD 365) = USD 365 + USD 73 = USD 438
If the gross amount is USD 365, then the net amount after adding 20 percent is USD 438.
Net amount refers to the final total after deductions or additions have been made whereas gross amount refers to the total amount before any deductions or additions have been made.
Us the formula:
Net Amount = Gross Amount + (Gross Amount x Percentage)
Given that,
Gross amount = $365
The given percentage = 20%
We can write 20% = 20/100
So, 20% = 0.2
Now put the values into the formula
Net amount = 365 + (365 x 0.2)
Net amount = 365 + 73
Net amount = 438
Hence,
The net amount is USD 438.

2. An equation for a line is = 6/5 . What will the new equation of this line be after it is rotated 90° counterclockwise around the origin
If new equation of this line be after it is rotated 90° counterclockwise around the origin, the equation of the new line after rotation is y = (-5/6)x
To find the new equation of a line after it is rotated 90° counterclockwise around the origin, we need to use the following formula:
(x', y') = (-y, x)
where (x, y) are the coordinates of a point on the original line, and (x', y') are the coordinates of the corresponding point on the new line after rotation.
We can start by finding the slope of the original line, which is given by:
y = (6x/5)
Rearranging this equation, we get:
x = (5/6)y
This tells us that the slope of the original line is 5/6.
To find the equation of the new line after rotation, we need to apply the formula above to two points on the original line. Let's choose two easy points to work with, such as (0,0) and (5,6).
Using the formula, we can find the new coordinates of these points after rotation:
(0', 0') = (-0, 0) = (0,0)
(5', 6') = (-6, 5)
Now we can find the slope of the new line using these two points:
slope = (6' - 0') / (5' - 0') = 5/-6 = -5/6
In summary, to find the new equation of a line after rotating 90° counterclockwise around the origin, we can use the formula (x', y') = (-y, x) to find the new coordinates of two points on the original line, and then use these points to find the slope of the new line. In this case, the new equation of the line is y = (-5/6)x.
