2. Ellen says that 1 2/5 equals 5 dived 7. Is she
correct? Explain.

Answer:

| - 19 - (- 8) |

Step-by-step explanation:

Given that the 2 points have the same x- coordinate, then the distance between the 2 points is the difference in the y- coordinates, that is

distance = | - 19 - (- 8) | = | - 19 + 8 | = | - 11 | = 11

Or

distance = | - 8 - (- 19) | = | - 8 + 19 | = | 11 | = 11

Is Square Root of 25 Rational or Irrational?  

Step-by-step explanation:

A rational number can be expressed in the form of p/q. Because √25 = 5 and 5 can be written in the form of a fraction 5/1. It proves that √25 is rational.

The answer is:

Work/explanation:

What are rational numbers?

Rational numbers are integers and fractions.

Irrational numbers are numbers that cannot be expressed as fractions, such as π.

Now, \(\bf{\sqrt{25}}\) can be simplified to 5 or -5; both of which are rational numbers.

The slope of this line is 0. If you graph the line y=10, for any x value, the y-value remains 10 (denoted because x is equal to 0 in the actual equation shown, which means that x will not be shown in the equation). The graph would basically just be a straight horizontal line, neither curving up or down.

The free energy for the reaction determined to be 244.5 kJ/mol, this thermodynamic parameter plays a crucial role in understanding the spontaneity and feasibility of the reaction at a given temperature. A negative value of free energy indicates that the reaction is exergonic, meaning it releases energy and is likely to proceed spontaneously under standard conditions.

Given values:

AG° = 63.1 kJ/mol

Partial pressure of A = 11.5 atm

Partial pressure of B = 8.60 atm

Partial pressure of C = 0.510 atm

Number of moles of gas A = 3

Number of moles of gas B = 1

Number of moles of gas C = 2

Free energy can be determined by the formula:

ΔG° = ΔG°f(Products) - ΔG°f(Reactants)

As per the reaction:

3 A(g) + B(g) → 2 C(g)

So, the number of moles of gases in the reactants = 3 + 1 = 4

Number of moles of gases in the products = 2

Thus, Δngas = 2 - 4 = -2

Using the formula:

AG° = RTlnK

And taking the natural log of K:

lnK = (-ΔG°) / RT

lnK = (-ΔG°) / 2.303RT

On putting the values in the formula:

lnK = - (63.1 x 1000) / (2.303 x 8.314 x 1120)

lnK = - 0.0246

On finding K:

K = e^(-0.0246)

The equilibrium constant for the reaction can be given by the following expression:

K = (PC^2) / (PA^3 x PB)

ΔG° = - RTlnK = - (8.314 × 1120 × (- 0.0246)) = 244.5 kJ/mol

Therefore, the free energy for the reaction is 244.5 kJ/mol.

There are 184,756 possible 9 player batting orders for a softball team with 20 players.

The formula to calculate the combination number of possible batting orders for a team with n players is n!/(n-r)! where n = the total number of players, and r = the number of players in the batting order. Therefore, for a softball team with 20 players, the number of possible 9 player batting orders is 20!/(20-9)! = 184,756.

20! = 20 × 19 × 18 × 17 × 16 × 15 × 14 × 13 × 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

(20-9)! = (20 - 9) × (19 - 9) × (18 - 9) × (17 - 9) × (16 - 9) × (15 - 9) × (14 - 9) × (13 - 9) × (12 - 9) × (11 - 9) × (10 - 9) × (9 - 9)

20!/(20-9)! = 184,756

Therefore, there are 184,756 possible 9 player batting orders for a softball team with 20 players.

The height of the right triangle is 24 centimeters. This is determined by solving the equation for the area of the triangle, which is given as 96 cm², and considering that the height is 3 times the length of the base. By substituting the values and solving the equation, we find that the height is indeed 24 centimeters.

To determine the height of the right triangle, we can use the formula for the area of a triangle, which is given by the formula A = (1/2) * base * height. In this case, the area is known to be \(96 cm^2\).

Let's denote the length of the base as x. According to the problem statement, the height is 3 times the length of the base, so the height can be expressed as 3x.

Substituting these values into the area formula, we get:

\(96 = (1/2) * x * 3x\)

Simplifying the equation:

\(96 = (3/2) * x^2\)

To solve for x, we can divide both sides of the equation by (3/2):

\(64 = x^2\)

Taking the square root of both sides, we find:

x = 8

Since the height is 3 times the length of the base, the height is:

3 * 8 = 24 centimeters.

Therefore, the height of the right triangle is 24 centimeters.

Answer:

Step-by-step explanation:

The two vectors [2x + 4y; 6x + 8y] and [2x; 2y], we can see that they are not equal. Therefore, lambda = 2 is not an eigenvalue of matrix A. To determine if lambda is an eigenvalue of the matrix A, we need to find if there exists a non-zero vector v such that Av = lambda * v.

1. Let's start by computing the matrix-vector product Av.
2. Multiply each element of the first row of matrix A by the corresponding element of vector v, then sum the results. Repeat this for the other rows of A.
3. Next, multiply each element of the resulting vector by lambda.
4. If the resulting vector is equal to lambda times the original vector v, then lambda is an eigenvalue of matrix A. Otherwise, it is not.

For example, consider the matrix A = [1 2; 3 4] and lambda = 2.
Let's find if lambda is an eigenvalue of A by solving the equation Av = lambda * v.

1. Assume v = [x; y] is a non-zero vector.
2. Compute Av: [1 2; 3 4] * [x; y] = [x + 2y; 3x + 4y].
3. Multiply the resulting vector by lambda: 2 * [x + 2y; 3x + 4y] = [2x + 4y; 6x + 8y].
4. We need to check if this result is equal to lambda times the original vector v = 2 * [x; y] = [2x; 2y].

Comparing the two vectors [2x + 4y; 6x + 8y] and [2x; 2y], we can see that they are not equal. Therefore, lambda = 2 is not an eigenvalue of matrix A.

In summary, to determine if lambda is an eigenvalue of matrix A, we need to find if Av = lambda * v, where v is a non-zero vector. If the equation holds true, then lambda is an eigenvalue; otherwise, it is not.

Step-by-step explanation:

on the first step, where the student subtracted the two equations, when they subtracted 3y - y, they got 4y, but they were supposed to get 2y.

If they did it right it would look like this

 2x + 3y = 8

-(2x  +  y = 16)

0x + 2y = -8

y = -4

2x - 4 = 16

2x = 20

x = 10

Solution (10,-4)

You must find the error, I will correct their work.

This is a system of linear equations. To solve it, you can use the substitution method. First, you can solve the first equation for x and substitute it into the second equation:

2x + 3y = 8

2x = 8 - 3y

x = (8 - 3y) / 2

2((8 - 3y) / 2) + y = 16

8 - 3y + 2y = 16

5y = 8

y = 8 / 5

Then, you can substitute y into the first equation:

2x + 3(8 / 5) = 8

2x = 8 - 24 / 5

2x = 16 / 5

x = 16 / 10

Therefore, the solution to the system of linear equations is x = 16/10 and y = 8/5.

Here is a sample correction to this (paraphrase):

When you tried to solve the system of linear equations, you likely made a mistake when solving one of the equations for a variable or when substituting the values into the equations. To ensure that you get the correct solution, you should double-check your work and make sure that the values you get satisfy the original equations.
