Taylor polynomial T3(x) for the respective functions, f(x) = xe\(^(-7x)\)and f(x) = x + e\(^(-x)\), centered at a = 0.
How we find Taylor polynomial?
For the first problem:
The Taylor polynomial T3(x) for the function f(x) = xe\(^\)\(^(-7x)\)centered at a = 0 is found by evaluating the function and its derivatives at x = 0 up to the third order.
By calculating the derivatives of f(x) and evaluating them at x = 0, we obtain f(0) = 0, f'(0) = 1, f''(0) = -14, and f'''(0) = 98.
Using these values, the Taylor polynomial T3(x) can be constructed as T3(x) = x - 7x\(^2\) + 49/3 x\(^3\).
This polynomial approximates the behavior of the original function f(x) around x = 0 up to the third degree.
For the second problem:
The Taylor polynomial T3(x) for the function f(x) = x + e\(^(-x)\) centered at a = 0 is obtained by evaluating the function and its derivatives at x = 0 up to the third order.
By calculating the derivatives of f(x) and evaluating them at x = 0, we get f(0) = 0, f'(0) = 1, f''(0) = 1, and f'''(0) = -1.
Using these values, the Taylor polynomial T3(x) can be written as T3(x) = x + 1/2 x\(^2\) - 1/6 x\(^3\).
This polynomial provides an approximation of the original function f(x) near x = 0 up to the third degree.
It allows us to estimate the behavior of the function and calculate its values within a certain range around x = 0.

which of the following best explans why the monopolists marginal revenue is less than the sales price
Monopolists are firms that have control over the supply of a particular product or service in a market. Due to this control, they can charge higher prices than competitive firms, which can result in lower quantities sold.
One reason why a monopolist's marginal revenue is less than the sales price is due to the downward-sloping demand curve. As the monopolist increases its sales price, the quantity demanded decreases. This means that the revenue generated from each additional unit sold is lower than the revenue generated from the previous unit sold. In other words, the marginal revenue earned from each unit sold is less than the sales price. This occurs because the monopolist must lower the price of all units sold to sell additional units, which lowers the average revenue earned per unit.
To illustrate this, imagine a monopolist that sells widgets for $10 each. If the monopolist lowers the price to $9, it may sell 10 widgets, resulting in revenue of $90 ($9 x 10). However, if the monopolist maintains the $10 price and only sells 9 widgets, the revenue is $90 ($10 x 9). In this case, the marginal revenue for the 9th unit sold is $0, which is less than the sales price of $10. This is because the monopolist must lower the price of all units sold to sell the additional unit, resulting in a decrease in average revenue per unit. Overall, the monopolist's marginal revenue is less than the sales price due to the downward-sloping demand curve and the need to lower prices to sell additional units.
A monopolist, unlike firms in a competitive market, has significant market power due to the absence of competition. This allows the monopolist to control the market price of their product by adjusting the quantity supplied. When a monopolist wants to sell an additional unit, they must lower the sales price for all units, including the ones already being sold. This is because the demand curve faced by a monopolist is downward-sloping, meaning that in order to sell more units, the monopolist has to decrease the price.
Marginal revenue refers to the additional revenue gained from selling one more unit of the product. As the monopolist lowers the sales price to sell more units, two things happen: the revenue increases from the additional unit sold, but there is also a loss in revenue from the units that were sold at a higher price before the price reduction.
As a result, the marginal revenue is less than the sales price, since it takes into account not only the revenue from the additional unit sold but also the loss of revenue from lowering the price of all units. This relationship between the monopolist's pricing strategy and marginal revenue is a key factor in determining the monopolist's profit-maximizing level of output and price.

The data in the table above was compiled by a new pet information website from a random survey of users with Basset Hounds and Welsh Corgis. Which statement best compares the height of the two breeds based on the collected data?
An adult Welsh Corgi is always going to be shorter than an adult Basset Hound.
Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.
There is no noticeable difference in the height of the two breeds since the Mean Absolute Deviation for each breed is roughly the same.
It is impossible to make a valid conclusion because the sample sizes are too small.
Answer:
An adult Welsh Corgi is always going to be shorter than an adult Basset Hound.
Step-by-step explanation:
That's what I think because the Basset Hound is 13.8 in. in height right? So he's two inches taller if we round up both numbers. Basset hound would be 14 and welsh corgi would be 11....................okay im not sure i give up but it's either
"An adult Welsh Corgi is always going to be shorter than an adult Basset Hound."
"Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.

Matilda asked 20 random people in the street if they would like to discuss what they want to do during the summer break. seven of them said yes. how is this sample biased? the people who chose to participate might not be similar to the people who didn’t. she should have asked more people. she should have asked girls only. the number of people who agreed was too small.
The sample is biased because sample size is too small. So option (1) she should have asked more people is the correct answer.
Sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower or higher sampling probability than others. Sampling bias occurs when some members of a population are systematically more likely to be selected in a sample than others.
For the given situation,
Sample size = 20
Here Matilda have surveyed only 20 people. Since it is a less value, the sample is biased.
We could not take as the population suggestion with the suggestion of only seven people.
To know the population's liking's, Matilda should have asked more people in the street if they would like to discuss what they want to do during the summer break asked more number of people in the population.
Hence we can conclude that the sample is biased because sample size is too small. So option (1) she should have asked more people is the correct answer.

a diver was collecting water samples from a lake. he collected a sample at every 3m, starting at 5m below water surface. the final sample was collected at a depth of 35m.how many sample did he collected
The diver collected water samples at every 3 meters, starting from 5 meters below the water surface, up to a final depth of 35 meters.
We can find the number of samples collected by dividing the total depth range by the distance between each sample and then adding 1 to include the first sample.
The total depth range is:
35 m - 5 m = 30 m
The distance between each sample is 3 m, so the number of samples is:
(30 m) / (3 m/sample) + 1 = 10 + 1 = 11
Therefore, the diver collected a total of 11 water samples.

If you invest $3,750 at the end of each of the next six years at
1.9% p.a., how much will you have after 6 years?
Group of answer choices
$14,985
$25,471
$23,596
$33,673
If you invest $3,750 at the end of each of the next six years at an interest rate of 1.9% per annum, you will have approximately $23,596 after 6 years.
To calculate the total amount accumulated after 6 years, we can use the formula for the future value of an ordinary annuity. The formula is given as:
Future Value = Payment * [(1 + Interest Rate)^n - 1] / Interest Rate
Here, the payment is $3,750, the interest rate is 1.9% per annum (or 0.019 as a decimal), and the number of periods (years) is 6.
Substituting the values into the formula:
Future Value = $3,750 * [(1 + 0.019)^6 - 1] / 0.019
= $3,750 * (1.019^6 - 1) / 0.019
≈ $23,596
Therefore, after 6 years of investing $3,750 at the end of each year with a 1.9% interest rate per annum, you would have approximately $23,596. Hence, the correct answer is $23,596.

Answer:
the point at which your line cut your y axis is the intercept
Answer:
Alternatively, we can determine the x-intercept and the y-intercept of the standard form linear inequality by substituting y = 0, then solve for x and substituting x = 0, then solve for y respectively. Recall that the x-intercept is the value of x when y = 0 and the y-intercept is the value of y when x = 0.

consider the vectors x and a and the symmetric matrix a. i. what is the first derivative of at x with respect to x? ii. what is the first derivative of xt ax with respect to x? what is the second derivative?
The first derivative of at x with respect to x is simply the transpose of the matrix a.The first derivative of xt ax with respect to x is 2ax, since taking the derivative of the product of two vectors involves multiplying one of the vectors by the derivative of the other vector, and in this case the derivative of x is the identity matrix (since x is a vector and not a matrix).The second derivative of xt ax with respect to x is simply the matrix 2a, since the second derivative involves taking the derivative of the first derivative.1. Given the vector x and the symmetric matrix A.
2. We need to find the first and second derivatives of the following expressions:
i. A * x
ii. x^T * A * x
The question involves vectors, symmetric matrices, and derivatives. Let's break it down step-by-step.
i. First derivative of A * x with respect to x:
To find the derivative of A * x with respect to x, we treat A as a constant matrix. The first derivative is simply the matrix A itself.
Answer: The first derivative of A * x with respect to x is A.
ii. First derivative of x^T * A * x with respect to x:
To find the first derivative of this expression, we'll use the following formula for the derivative of a quadratic form:
d/dx (x^T * A * x) = (A + A^T) * x
Since A is a symmetric matrix, A = A^T. Therefore, the formula becomes:
d/dx (x^T * A * x) = 2 * A * x
Answer: The first derivative of x^T * A * x with respect to x is 2 * A * x.
iii. Second derivative of x^T * A * x with respect to x:
The second derivative of x^T * A * x with respect to x is the derivative of the first derivative (2 * A * x) with respect to x. Since A is a constant matrix, the second derivative is zero.
Answer: The second derivative of x^T * A * x with respect to x is 0.

Find the value of the variables
Answer:
x = 121 degrees
y = 59 degrees
w = 59 degrees
z = 53 degrees
v = 121 degrees
Step-by-step explanation:
31 + 90 + w = 180 ==> these three angles are in the top left triangle.
Triangles add up to 180 degrees
121 + w = 180 ==> solve for w
w = 59 degrees
y = w ==> these angles are opposite adjacent angles; they are congruent
y = 59 degrees ==> Both angles are equal. So both angles are 59 degrees
68 + y + z = 180 ==> triangles add up to 180 degrees
68 + 59 + z = 180 ==> plugin 59 for y
127 + z = 180 ==> solve for z
z = 53 degrees ==> subtract 137 on both sides
w + x = 180 ==> w and x are on a straight line.
Straight lines add up to 180 degrees.
59 + x = 180 ==> plugin 59 for w
x = 121 degrees ==> subtract 59 on both sides
v + y = 180 ==> v and y are also on a straight line.
v + 59 = 180 ==> plugin 59 for y
v = 121 degrees ==> subtract 59 on both sides
x = 121 degrees
y = 59 degrees
w = 59 degrees
z = 53 degrees
v = 121 degrees
Write the coordinates of the vertices after a rotation 90 degrees counterclockwise around the origin.
Answer: J' (8, -9); K' (8, -2); L' (3, -2); M' (3, -9)
Step-by-step explanation:
A rotation of 90 degrees counterclockwise is (x, y) -> (-y, x), so
J (-9, -8) -> J' (8, -9)
First, you take negative 8 (y) of J and make it positive 8 for the x of J'. Then, take -9 (y) of J and switch it to x of J'.
You repeat this process for the rest of the points. X switches to Y with the opposite sign and Y switches to X but stays the same.
