Which axis is triangle ABC reflected across?

(a) The game tree for n = 4 cards can be represented as follows:

markdown

       Alice

      /  |  |  \

     1   3  4   5

    /     |     \

  Bob     |     Dave

  / \     |     / \

 3   4    5    1   3

b here is a bijection between the set of valid games for n cards and a particular subset of subgraphs of K4.n.

In this game tree, each level represents a player's turn, starting with Alice at the top. The numbers on the edges represent the cards played by each player. At each level, the player has multiple choices depending on the available cards. The game tree branches out as each player makes their move, and the game continues until all cards have been played or no valid moves are left.

(b) To prove the bijection between the set of valid games for n cards and a subset of subgraphs of K4.n, we can associate each player's move in the game with an edge in the bipartite graph. Let's consider a specific example with n = 4.

In the game, each player chooses a card from their hand that hasn't been played before. We can represent this choice by connecting the corresponding vertices of the bipartite graph. For example, if Alice plays card 2, we draw an edge between the vertex representing Alice and the vertex representing card 2. Similarly, Bob's move connects his vertex to the chosen card, and so on.

By following this process for each player's move, we create a subgraph of K4.n that represents a valid game. The set of all possible valid games for n cards corresponds to a subset of subgraphs of K4.n.

Therefore, there is a bijection between the set of valid games for n cards and a particular subset of subgraphs of K4.n.

This question is about Probability, and the probability is the number of outcomes of the event we try to find the probability over the number of outcomes in the sample space, that is, the number of all the cases we need to analyze.

In this case, we have that the sample space is the total number of persons:

1. Women: 7

2. Men: 3

Then, the number of outcomes in the sample space is women + men = 7 + 3 = 10.

We can say the event is a woman in that sample space, we have 7 women.

Therefore, the event that a person is a woman is:

In summary, the probability to find a person that is a woman in an office is:

Therefore, David had 5 wrong answers.

To find out how many wrong answers David had, we need to calculate the number of correct answers first. Since each correct answer is awarded 10 points, and David scored a total of 75 points, we can divide 75 by 10 to find the number of correct answers.

75 ÷ 10 = 7.5

Since we can't have half a correct answer, we can conclude that David had 7 correct answers.

Now, to find the number of wrong answers, we subtract the number of correct answers from the total number of questions. In this case, there were 12 questions in total.

12 - 7 = 5

Therefore, David had 5 wrong answers.

So the probability, rounded to the nearest thousandth, of getting at least 2 fours in 5 rolls of a fair die is 0.194.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

The probability of getting at least 2 fours is the sum of the probabilities of getting exactly 2, 3, 4, or 5 fours:

P(X ≥ 2) = P(X=2) + P(X=3) + P(X=4) + P(X=5)

Using the binomial formula, we can calculate each of these probabilities:

P(X=k) = (n choose k) p^k (1-p)^(n-k)

where (n choose k) is the binomial coefficient, which represents the number of ways to choose k items from n distinct items.

P(X=2) = (5 choose 2) (1/6)² (5/6)³ = 0.1608

P(X=3) = (5 choose 3) (1/6)³ (5/6)² = 0.0322

P(X=4) = (5 choose 4) (1/6)⁴ (5/6)¹ = 0.0013

P(X=5) = (5 choose 5) (1/6)⁵ (5/6)⁰ = 0.00003

Therefore,

P(X ≥ 2) = 0.1608 + 0.0322 + 0.0013 + 0.00003 = 0.1943

So the probability, rounded to the nearest thousandth, of getting at least 2 fours in 5 rolls of a fair die is 0.194.

The work done in lifting the lower end of the chain to the ceiling is 833.33 ft·lb.

To find the work done in lifting the lower end of the chain to the ceiling, we can use the concept of work as the integral of force over a displacement.

Let's consider a small segment of the chain of length dx at a distance x from the lower end. The weight of this small segment can be approximated as the weight of a point mass located at its midpoint, which is x/2 ft from the lower end. The weight of this small segment is then (25 lb/10 ft) * (x/2 ft) = (5/2) * x lb.

To calculate the work done in lifting this small segment, we need to multiply the weight by the distance it is lifted. The distance lifted is simply x ft.

So, the work done in lifting this small segment is (5/2) * x lb * x ft = (5/2) * x^2 ft·lb.

To find the total work done in lifting the entire chain, we need to sum up the work done for all the small segments. We can express this as an integral:

W = ∫[0, 10] (5/2) * x^2 dx

Integrating this expression:

W = (5/2) * (x^3/3) |[0, 10]

W = (5/2) * (10^3/3) - (5/2) * (0^3/3)

W = (5/2) * (1000/3)

W = (5000/6) ft·lb =833.33

Therefore, the work done in lifting the lower end of the chain to the ceiling is 833.33 ft·lb.

The given initial value problem's solution is y(t) = e^(-2t)(2cos(4t) + (1/8)sin(4t))

To solve the given initial value problem, we can use the method of solving second-order homogeneous linear differential equations with constant coefficients.

The characteristic equation corresponding to the given differential equation is:

r^2 + 4r + 20 = 0

To solve this quadratic equation, we can use the quadratic formula:

r = (-b ± √(b^2 - 4ac)) / (2a)

In this case, a = 1, b = 4, and c = 20. Substituting these values into the quadratic formula, we get:

r = (-4 ± √(4^2 - 4(1)(20))) / (2(1))

r = (-4 ± √(-64)) / 2

r = (-4 ± 8i) / 2

r = -2 ± 4i

The roots of the characteristic equation are complex conjugates: -2 + 4i and -2 - 4i.

The general solution of the differential equation can be written as:

y(t) = e^(-2t)(c1cos(4t) + c2sin(4t))

To find the particular solution that satisfies the initial conditions, we substitute the initial values into the general solution and solve for the constants c1 and c2.

Given y(0) = 2:

2 = e^(-2(0))(c1cos(4(0)) + c2sin(4(0)))

2 = c1

Given y'(0) = -1:

-1 = -2e^(-2(0))(c1sin(4(0)) + 4c2cos(4(0)))

-1 = -2(1)(0 + 4c2)

-1 = -8c2

c2 = 1/8

Therefore, the particular solution that satisfies the initial conditions is:

y(t) = e^(-2t)(2cos(4t) + (1/8)sin(4t))

This is the solution to the given initial value problem.

Answer:

Sooo.... She is bragging to us that she can just use 180$ or what?

a) The relationship between b and c is that c cannot be zero.

b) b can be any nonzero constant and c is equal to 2.5 in this case.

In two dimensions, the compatibility equations for strain are,0

∂εx/∂y + ∂γxy/∂x = 0

∂εy/∂x + ∂γxy/∂y = 0

where εx and εy are the normal strains in the x and y directions, respectively, and γxy is the shear strain.

Using the given strain field, we can calculate the strains,

εx = -4.5cx² + 10.5cy

εy = 1.5cx² - 7.5cy²

γxy = 1.5bxy

Taking partial derivatives and plugging them into the compatibility equations, we get,

⇒ -9cx + 0 = 0

⇒ 0 + (-15cy) = 0

These equations must be satisfied for the strain field to be compatible. From the first equation,

We get cx = 0, which means c cannot be zero.

From the second equation, we get cy = 0,

Which means b can be any nonzero constant.

For part b:

We are asked to find the displacements u and v corresponding to the given strain field at points (3, 7), assuming they are zero at point (0, 0) and using c = 2.5.

To find the displacement components,

We need to integrate the strains with respect to x and y. We get,

u = ∫∫εx dx dy = ∫(10.5cy) dy = 5.25cy²

v = ∫∫εy dx dy = ∫(1.5cx² ) dx - ∫(7.5cy²) dy = 0.5cx³ - 2.5cy³

Plugging in the values of c and b, we get,

u = 5.25(2.5)(7)²  = 767.62

v = 0.5(2.5)(3)³ - 2.5(7)³ = -8583.75

Therefore,

The displacements at points (3, 7) are u = 767.62 and v = -8583.75.

To determine if a function has a vertical asymptote, you need to consider its behavior as the input approaches certain values.

A vertical asymptote occurs when the function approaches positive or negative infinity as the input approaches a specific value. Here's how you can determine if a function has a vertical asymptote:

Check for restrictions in the domain: Look for values of the input variable where the function is undefined or has a division by zero. These can indicate potential vertical asymptotes.

Evaluate the limit as the input approaches the suspected values: Calculate the limit of the function as the input approaches the suspected values from both sides (approaching from the left and right). If the limit approaches positive or negative infinity, a vertical asymptote exists at that value.

For example, if a rational function has a denominator that becomes zero at a certain value, such as x = 2, evaluate the limits of the function as x approaches 2 from the left and right. If the limits are positive or negative infinity, then there is a vertical asymptote at x = 2.

In summary, to determine if a function has a vertical asymptote, check for restrictions in the domain and evaluate the limits as the input approaches suspected values. If the limits approach positive or negative infinity, there is a vertical asymptote at that value.
