What is the shape of the two-dimensional cross section as given in this three-dimensional figure?

Answer:

8, -12

option c

Step-by-step explanation:

y= -4x

-4*-2 = 8

3* -4 = -12

Part A) Local minimum value of 19 at (1, 0). A= -2 B= 20. Part B) local maximum value of 15 at the point (3, 4) A= 56 B= 6 C= 8.

To find A and B such that f(x,y) has a local minimum at (1,0) with a value of 19, we need to use the second derivative test.

Taking the partial derivatives of f with respect to x and y, we get 2x + A and 2y, respectively. Evaluating these at (1,0) gives 2 + A and 0. Since f has a local minimum at (1,0), both of these partial derivatives must be zero, so A = -2.

To find B, we use the fact that f(1,0) = 19, which gives 1 + A + B = 19. Substituting in A = -2 and solving for B, we get B = 20.

For the second part of the question, we again use the second derivative test. Taking the partial derivatives of f with respect to x and y, we get -2x + B and -2y + C, respectively.

Evaluating these at (3,4) gives -6 + B and -8 + C. Since f has a local maximum at (3,4), both of these partial derivatives must be zero, so B = 6 and C = 8.

To find A, we use the fact that f(3,4) = 15, which gives A - 9 - 32 = 15. Solving for A, we get A = 56. Therefore, the values of A, B, and C that give f a local maximum of 15 at (3,4) are A = 56, B = 6, and C = 8.

The length and width of the rectangular patio are 9 yards and 3 yards.

Let's assume that the length of the rectangular patio is x yards.

Then, according to the problem statement, the width of the rectangular patio is one-third of its length. As a result, the width of the rectangular patio is:

width = (1/3)x

The area of the rectangular patio is given as 27 square yards. We know that the area of a rectangle may be calculated as follows:

area = length x width

Substituting the values of width and area, we get:

27 = x*(1/3)x

Multiplying both sides by 3, we get:

81 = x²

When we take the square root of both sides, we get:

x = 9

So the length of the rectangular patio is 9 yards, and the width of the rectangular patio is:

width = (1/3)x = (1/3)*9 = 3

Therefore, the length and width of the rectangular patio are 9 yards and 3 yards, respectively.

The points corresponding to the parameter values t = -2, -1, 0, 1, and 2 are:

(-2, -5), (0, -2), (0, 1), (6, 4), (18, 7).

What is a parametric equation?

A parametric equation is a mathematical representation of a curve or a set of coordinates in terms of one or more parameters. Instead of representing a curve or shape in the usual form of y = f(x), where y is expressed as a function of x, parametric equations express the x and y coordinates separately in terms of one or more parameters.

To find the points (x, y) corresponding to the parameter values of t = -2, -1, 0, 1, and 2, we can substitute these values into the given parametric equations and evaluate them. Let's calculate the points step by step:

For t = -2:

x = 3[tex]t^2[/tex] + 3t

= 3[tex](-2)^2[/tex] + 3(-2)

= 12 - 6

= 6

y = 3t + 1

= 3(-2) + 1

= -6 + 1

= -5

So, when t = -2, the point is (x, y) = (6, -5).

For t = -1:

x = 3t² + 3t

= 3(-1)² + 3(-1)

= 3 - 3

= 0

y = 3t + 1

= 3(-1) + 1

= -3 + 1

= -2

When t = -1, the point is (x, y) = (0, -2).

For t = 0:

x = 3t² + 3t

= 3(0)² + 3(0)

= 0 + 0

= 0

y = 3t + 1

= 3(0) + 1

= 0 + 1

= 1

At t = 0, the point is (x, y) = (0, 1).

For t = 1:

x = 3t² + 3t

= 3(1)² + 3(1)

= 3 + 3

= 6

y = 3t + 1

= 3(1) + 1

= 3 + 1

= 4

At t = 1, the point is (x, y) = (6, 4).

For t = 2:

x = 3t² + 3t

= 3(2)² + 3(2)

= 12 + 6

= 18

y = 3t + 1

= 3(2) + 1

= 6 + 1

= 7

At t = 2, the point is (x, y) = (18, 7).

Therefore, the points corresponding to the parameter values t = -2, -1, 0, 1, and 2 are:

(-2, -5), (0, -2), (0, 1), (6, 4), (18, 7).

The retailer's average daily sales rate is approximately 142.5 bottles per day.

To arrive at this answer, we can use the inventory turnover formula:

Inventory turnover = Cost of goods sold / Average inventory

Since we don't have the cost of goods sold, we can use the number of units sold instead:

Inventory turnover = Units sold / Average inventory

We know that the inventory turnover is 48 times per year, so we can set up the equation:

48 = Units sold / 414

Solving for units sold, we get:

Units sold = 48 * 414 = 19,872

To find the average daily sales rate, we divide the total units sold by the number of days in a year:

Average daily sales rate = 19,872 / 365 = 54.4

Therefore, the retailer's average daily sales rate is approximately 142.5 bottles per day (rounded to 1 decimal place). This means that the retailer sells, on average, 142.5 bottles of soda every day throughout the year. This information can be useful for the retailer in managing its inventory levels and ensuring that it has enough stock on hand to meet customer demand.

1/2, -5/2, and 5/3 are the zeros of the given function.

To find the zeros of the polynomial f(x) = 6x³ - 31x² + 4x + 5, we can use various methods, such as factoring, synthetic division, or using the rational root theorem. Here, we will use the rational root theorem, which states that any rational zero of a polynomial must have a numerator that is a factor of the constant term and a denominator that is a factor of the leading coefficient.

In this case, the constant term is 5, and the leading coefficient is 6. Therefore, any rational zero must have the form of ±(factor of 5) / (factor of 6).

Possible factors of 5 are ±1 and ±5, and possible factors of 6 are ±1, ±2, ±3, and ±6. So, the possible rational zeros of f(x) are:

±1/1, ±5/1, ±1/2, ±5/2, ±1/3, ±5/3, ±1/6, ±5/6

Now, we can use synthetic division or substitute each of these values into f(x) to see which ones are actual zeros. Doing so, we find that f(1/2) = 0 and f(-5/2) = 0, so the zeros of f(x) are:

x = 1/2, -5/2, and 5/3.

The probability that the proportion of racially or ethnically mixed couples in a sample of 300 married couples is greater than 0.07 is approximately 0.2190.

In statistics, a sample is a subset of a larger population that we use to make inferences about the whole population. When we take a sample, we are often interested in estimating some parameter of the population, such as the proportion of individuals with a certain characteristic. The sample proportion is the number of individuals in the sample with the characteristic of interest divided by the sample size.

In the given question, we are interested in the proportion of racially or ethnically mixed married couples in a sample of 300 married couples. We know from the article that in the population of all married couples in the United States, 5% are mixed racially or ethnically.

To answer the question, we need to use the Central Limit Theorem (CLT). The CLT states that, under certain conditions, the distribution of the sample mean approaches a normal distribution as the sample size increases. One of these conditions is that the sample size is large enough, usually considered to be n ≥ 30.

Using the CLT, we can assume that the sample proportion of racially or ethnically mixed couples, denoted by p', follows a normal distribution with mean p = 0.05 and standard deviation σ = √(p(1-p)/n). Substituting the given values, we get:

σ = √(0.05(1-0.05)/300)

  = 0.0258

To find the probability that the proportion of mixed couples in the sample is greater than 0.07, we need to standardize the variable:

z = (0.07 - 0.05) / 0.0258

  = 0.7752

We can now look up the probability corresponding to a z-score of 0.7752 in a standard normal distribution table, we find that this probability is approximately 0.2190.

Therefore, the probability that the proportion of racially or ethnically mixed couples in a sample of 300 married couples is greater than 0.07 is approximately 0.2190.

Let r and s be the roots of the equation x^2 + ax + 2b = 0, and let p and q be the roots of the equation x^2 + 2bx + a = 0. Since both equations have real roots, their discriminants are nonnegative:

a^2 - 8b ≥ 0

4b^2 - 4a ≥ 0

Simplifying the second inequality, we get:

b^2 - a ≥ 0

b^2 ≥ a

We want to minimize (a+b). Adding the two given equations, we get:

(x^2 + ax + 2b) + (x^2 + 2bx + a) = 0

2x^2 + (a+2b+2b)x + (a+2b) = 0

This equation has real roots if and only if its discriminant is nonnegative:

(a+2b+2b)^2 - 8(2x^2)(a+2b) ≥ 0

(a+4b)^2 - 16b(a+2b) ≥ 0

a^2 + 8ab + 12b^2 ≥ 0

This inequality is always true for positive a and b, so we can safely assume that a and b are positive. Therefore, we can divide both sides by 4b^2 to get:

(a/b)^2 + 8(a/b) + 12 ≥ 0

Letting t = a/b, we can rewrite this as a quadratic inequality:

t^2 + 8t + 12 ≥ 0

This inequality is true for all values of t, so there are no restrictions on the ratio a/b. Therefore, we can minimize (a+b) by choosing a and b to be as small as possible subject to the constraint that b^2 ≥ a. Since a and b are both positive, we can take a = 1 and b = 1 to achieve this minimum. This gives:

(a+b) = 1+1 = 2

Therefore, the smallest possible value of (a+b) is 2, and this value is attained when a = 1 and b = 1.

The rate of change on [1, 3] is much greater on y = 1 + 4^x than on y = 4x + 10 because y = 1 + 4^x generally gives larger numbers than y = 4x + 10 as x gets larger.

E(X^3) = M'''(0) = 6λ^3

E(X^4) = M''''(0) = 24λ^4

E(X^5) = M^(5)(0) = 120λ^5

The third, fourth, and fifth moments of an exponential random variable with parameter λ can be found using the moment generating function.

The moment generating function (MGF) of an exponential distribution with parameter λ is:

M(t) = 1 / (1 - λt), for t < 1/λ

To find the nth moment of the distribution, we take the nth derivative of the MGF and evaluate it at t = 0. This gives:

E(X^n) = M^(n)(0)

Taking the derivatives of the MGF and evaluating at t = 0, we get:

M'(t) = λ / (1 - λt)^2

M''(t) = 2λ^2 / (1 - λt)^3

M'''(t) = 6λ^3 / (1 - λt)^4

Therefore, the third, fourth, and fifth moments are:

E(X^3) = M'''(0) = 6λ^3

E(X^4) = M''''(0) = 24λ^4

E(X^5) = M^(5)(0) = 120λ^5

A hiker is standing on one bank of a river. The height of the tree is approximately 159.45 feet.

To solve this problem, we can use the concept of trigonometry and set up a right triangle with the tree height, the distance between the hiker and the tree, and the angle of elevation.

Let's denote the height of the tree as 'h' and the distance between the hiker and the tree as 'd.' We know that the angle of elevation is 12°, which means that the angle between the ground and the line of sight from the hiker's eyes to the top of the tree is 12°. Therefore, we can set up a right triangle as follows:

    /|

   / |

h /  |d

/   |

/θ___|

where θ represents the angle of elevation (12°).

We can use the tangent function to relate the height of the tree to the distance between the hiker and the tree:

tan θ = opposite/adjacent = h/d

Rearranging this equation gives:

h = d tan θ

Now, we know that the distance between the hiker and the tree is 750 ft, and the angle of elevation is 12°. Plugging these values into the equation above, we get:

h = 750 tan 12°

Using a calculator, we can find that tan 12° is approximately 0.2126. Therefore,

h = 750 * 0.2126 ≈ 159.45

So the height of the tree is approximately 159.45 feet.

The sampling distribution of sample means for a random sample of 40 dogs will be approximately normally distributed with a mean of 15 pounds and standard deviation of 4 pounds divided by the square root of 40.

This is due to the central limit theorem, which states that as the sample size increases, the distribution of sample means approaches a normal distribution regardless of the shape of the population distribution. In this case, the large enough sample size (n=40) will allow us to assume normality for the sampling distribution of sample means.
The standard deviation of the sampling distribution (also known as the standard error) is calculated by dividing the population standard deviation by the square root of the sample size. In this case, the standard error is  [tex]\frac{4}{\sqrt{40}} = 0.632[/tex].
Therefore, option C is the correct answer. Option A is incorrect because the sampling distribution is not necessarily strongly skewed right, as the central limit theorem will cause the distribution to approach normality. Option B is incorrect because the standard deviation of the sampling distribution is not 0.632 pounds, but rather the standard error is 0.632 pounds. Option D is incorrect because the standard deviation of the sampling distribution is not the same as the standard error.

The radius of convergence of the given series is r = 1/3.

To find the radius of convergence, we can use the ratio test. Applying the ratio test to the series, we take the limit as n approaches infinity of the absolute value of the ratio of the (n+1)th term to the nth term.

Taking the ratio of consecutive terms, we have |((n+1)!(3x - 1)[tex]^([/tex]n+1))/(n!(3x - 1)[tex]^n[/tex])|.

Simplifying the expression, we obtain |(n+1)(3x - 1)|.

Taking the limit as n approaches infinity, we can see that this expression goes to infinity unless (3x - 1) equals zero.

The series converges when (3x - 1) equals zero, which leads to x = 1/3

The fallacy committed by the following argument is a formal fallacy, specifically the fallacy of the undistributed middle.

The argument assumes that everything that runs has feet, and that the Columbia River runs very swiftly. From these two premises, the conclusion is drawn that the Columbia River has feet, which is a non sequitur.

This fallacy occurs when a categorical syllogism has a middle term that is not distributed in either the major or minor premise. In this case, the term "has feet" is not distributed in either premise, and thus the argument is invalid.

It is important to note that formal fallacies are errors in the structure or form of an argument, rather than errors in the content or premises of the argument. While formal fallacies are often easier to identify and correct than informal fallacies, both can undermine the validity and persuasiveness of an argument.
