A non-empty relation on set A which satisfies all the condition is {(10, 20), (20, 30), (30, 10)}.

To find a non-empty relation on set A = {10, 20, 30} that satisfies the given conditions (not reflexive, not transitive, and antisymmetric), we can define the following relation:

R = {(10, 20), (20, 30), (30, 10)}

Explanation:

Not Reflexive: A relation R on set A is reflexive if for every element x in A, (x, x) is in R. In this case, (10, 10), (20, 20), and (30, 30) are not present in the relation R, which makes it not reflexive.

Not Transitive: A relation R on set A is transitive if for every (x, y) and (y, z) in R, (x, z) is also in R. In this case, we have (10, 20) and (20, 30) in R, but (10, 30) is not present. Therefore, the relation R is not transitive.

Antisymmetric: A relation R on set A is antisymmetric if for every (x, y) and (y, x) in R, where x ≠ y, then x and y are not the same element. In this case, we have (10, 20) and (20, 10) in R, but 10 is not equal to 20. Similarly, we have (20, 30) and (30, 20) in R, but 20 is not equal to 30. Therefore, the relation R is antisymmetric.

By defining the relation R as {(10, 20), (20, 30), (30, 10)}, we satisfy all three conditions simultaneously: not reflexive, not transitive, and antisymmetric.

The true intercept and slope are both different from the estimated values based on statistical significance.

The p-value of the intercept coefficient and that of the slope coefficients are 0 and 0.02(2%) respectively. This means that they are statistically significant. Thus we can infer that the true intercept and slope is not equal to 0.

The standard error of the intercept coefficient is 6, which means that the true intercept is likely to be within 6 units of the estimated intercept. The standard error of the slope coefficient is 1, which means that the true slope is likely to be within 1 unit of the estimated slope.

Therefore, the true slope and intercept will be different from the estimated slope and intercept.

Answer:

The time the object will hit the ground is 2 s.

Step-by-step explanation:

Given;

h(t) = (-4.9t + 29.4)(t + 2)

Open the bracket;

h(t) = -4.9t² + 29.4t  -9.8t + 58.8

Answer:

m = 58°

x = 64°

Step-by-step explanation:

When a puck touches one side of the air hockey table,

All the angles formed are located at a point on a straight line.

Therefore, sum of angles formed is 180°.

m° + m° + 64° = 180°

2m + 64 = 180

2m = 180 - 64

2m = 116

m = 58°

m∠y = m = 58° [Alternate interior angles]

Similarly, on the other side of the table,

58° + y° + x° = 180°

58° + 58° + x° = 180°

x + 116° = 180°

x = 180 - 116

x = 64°

Answer:

The closest measurement is 69 meters.

Step-by-step explanation:

We already know that 22 meters is the diameter and to find the circumference you need to multiply the diameter with π. We don't know π, so we are going with 3.14. When you multiply 22 and 3.14 together, you get 69.08 meters. You round the answer to the nearest meter, so it's 69 meters. So, the closest measurement is 69 meters.

Evaluating this expression will give us the value of f(3).

To find the value of f(3), we need to integrate the second derivative of f(x) twice and use the given initial conditions to determine the constants of integration.

Step 1: Integrate the second derivative f''(x) with respect to x to find the first derivative f'(x):

∫(f''(x)) dx = ∫(9x + 5sin(x)) dx

f'(x) = (9/2)x^2 - 5cos(x) + C1

Step 2: Use the given initial condition f'(0) = 2 to find the constant C1:

f'(0) = (9/2)(0)^2 - 5cos(0) + C1

2 = 0 - 5 + C1

C1 = 7

Step 3: Integrate f'(x) with respect to x to find the function f(x):

∫(f'(x)) dx = ∫[(9/2)x^2 - 5cos(x) + 7] dx

f(x) = (9/6)x^3 - 5sin(x) + 7x + C2

Step 4: Use the given initial condition f(0) = 3 to find the constant C2:

f(0) = (9/6)(0)^3 - 5sin(0) + 7(0) + C2

3 = 0 - 0 + 0 + C2

C2 = 3

Now we have the function f(x):

f(x) = (9/6)x^3 - 5sin(x) + 7x + 3

To find f(3), substitute x = 3 into the function:

f(3) = (9/6)(3)^3 - 5sin(3) + 7(3) + 3

Therefore, Evaluating this expression will give us the value of f(3).

The solution is the zero function for all values of x and t.

To solve the heat equation u_t = 60u_xx with the given boundary and initial conditions, we can use separation of variables. We assume that u(x, t) can be written as a product of two functions, X(x) and T(t), such that u(x, t) = X(x)T(t).

Substituting this into the heat equation, we have:

X(x)T'(t) = 60X''(x)T(t)

Dividing both sides by 60X(x)T(t), we get:

T'(t)/T(t) = 60X''(x)/X(x)

The left side of the equation only depends on t, while the right side only depends on x. Since both sides are equal to a constant, we can set them equal to -λ², where λ is the constant.

T'(t)/T(t) = -λ²

X''(x)/X(x) = -λ²

Now, let's solve these two equations separately:

T'(t)/T(t) = -λ²

This is a separable ordinary differential equation. Integrating both sides with respect to t, we get:

∫ T'(t)/T(t) dt = ∫ -λ² dt

ln|T(t)| = -λ²t + C₁

Taking the exponential of both sides, we have:

T(t) = e^(-λ²t + C₁)

T(t) = e^(C₁) * e^(-λ²t)

T(t) = A * e^(-λ²t), where A = e^(C₁)

Now, let's solve the second equation:

X''(x)/X(x) = -λ²

This is also a separable ordinary differential equation. Integrating both sides with respect to x, we get:

∫ X''(x)/X(x) dx = ∫ -λ² dx

∫ (X''(x)/X(x)) dx = -λ²x + C₂

Using the fact that X''(x) = d²X(x)/dx², we can rewrite the equation as:

∫ (d²X(x)/dx²)/X(x) dx = -λ²x + C₂

∫ (d²X(x)/dx²) / X(x) dx = ∫ -λ² dx

∫ (1/X(x)) d²X(x)/dx² dx = -λ²x + C₂

Integrating both sides again, we have:

ln|X(x)| = -λ²x + C₂x + C₃

Taking the exponential of both sides, we get:

X(x) = e^(-λ²x + C₂x + C₃)

X(x) = e^(-λ²x) * e^(C₂x) * e^(C₃)

X(x) = B * e^(-λ²x) * e^(C₂x), where B = e^(C₃) * e^(C₂x)

Putting the solutions for T(t) and X(x) together, we have:

u(x, t) = X(x)T(t)

u(x, t) = (B * e^(-λ²x) * e^(C₂x)) * (A * e^(-λ²t))

We can combine the constants A and B into a single constant C:

u(x, t) = C * e^(-λ²x) * e^(C₂x) * e^(-λ²t)

Applying the boundary condition u(0, t) = 0, we have:

u(0, t) = C * e^(-λ²0) * e^(C₂0) * e^(-λ²t) = 0

This implies that C * e^(-λ²t) = 0. Since e^(-λ²t) is never zero, we must have C = 0.

Therefore, the solution to the heat equation with the given boundary and initial conditions is: u(x, t) = 0

The correct answer is: c. The n-th error term (e_n) can be predicted with e_n = 0.91 * e_n - 1.

This statement indicates that there is a correlation or relationship between consecutive error terms, where the n-th error term can be predicted based on the previous error term. In a simple linear regression model, the error terms are assumed to be independent and have no correlation with each other.

However, if there is a correlation between the error terms, it violates the assumption of independence, which can lead to biased and unreliable regression results. Therefore, this condition suggests that the result from the simple linear regression model could be potentially misleading.

Answer:

Step-by-step explanation:

First, you need to make sure that you know a few things.

1. A line is 180 degrees

2. Angles with the small boxes on them are right angles.

3. Angles that are across from each other are the same amount of degrees...

For example, look at angle 2, you can see that directly across from it is the angle 35 degrees, this makes angle 2 35 degrees as well.

In order to find angle 1, you need to subtract 35 from 180, to see how much is needed to fill the line, in this case it is 145.

So, angle 1 is 145 degrees, and angle two is 35.

One more thing, angles 1 and 7 are the same and so are 2 and 6 because they are on the same line, I can't remember why, but they are.

The limit of the given expression as x approaches infinity is negative infinity. The limit of (4[tex]x^2[/tex] + 2) as x approaches negative infinity is positive infinity. The limit of (2x + 5x + 3) divided by (2x + 3) as x approaches negative infinity is 7/4.

In the first limit, as x approaches infinity, the dominant term in the expression is 2x^2. Since x^2 grows without bound as x becomes larger, the value of 2x^2 will also increase without bound, resulting in a limit of negative infinity.

In the second limit, as x approaches negative infinity, the dominant term in the expression is 4x^2. Similar to the first limit, since x^2 grows without bound as x becomes more negative, the value of 4x^2 will increase without bound, leading to a limit of positive infinity.

In the third limit, as x approaches negative infinity, both the numerator and denominator have the dominant term of 5x. Dividing the numerator and denominator by 5x, we get (2 + 5/x) divided by (2 + 3/x). As x approaches negative infinity, the terms with x in the denominator become negligible, resulting in the limit simplifying to 2/2, which equals 1. Therefore, the limit of (2x + 5x + 3)/(2x + 3) as x approaches negative infinity is 7/4.
