What is 2/3 x 4/9 divided by 1/9? Please answer I need serious help.

The number of ways which are there to seat four of a group of ten people around a circular table is 1260.

To choose 4 people from a group of ten we need to count such people, which can be found using 10! / 4! × (10-4)! ,  after solving this we need to multiply 3! by this to get the desired answer. This is done because for that 4 people to sit in a circle, the possibilities for n people to sit around a circle is (n-1)! , and since n here is 4 the possibilities will also be (4-1)! which is 3! here.

Hence the final answer: 3! × 10! / 4! × (10-4)! = 1260

- Matrix A has distinct real eigenvalues.

- Matrix B has repeated real eigenvalues.

- Matrix C has distinct real eigenvalues.

- Matrix D has a distinct real eigenvalue.

To determine the nature of the eigenvalues of each matrix, we need to find the eigenvalues by solving the characteristic equation and then examine their properties.

Let's consider each matrix:

1. Matrix A:

[-5 -2 -3]

[ 8 41 18]

[90 40  3]

To find the eigenvalues, we solve the characteristic equation det(A - λI) = 0, where λ is the eigenvalue and I is the identity matrix.

det(A - λI) = 0

| -5-λ  -2    -3  |

|   8    41-λ  18 |

|  90    40     3-λ| = 0

Expanding the determinant and solving, we find the eigenvalues:

λ₁ ≈ 40.256

λ₂ ≈ 6.664

λ₃ ≈ -1.919

The eigenvalues are distinct real numbers.

2. Matrix B:

[ 3   3]

[-4   3]

[ 4 -2]

Again, solving the characteristic equation, we find the eigenvalues:

λ₁ = 3

λ₂ = 3

λ₃ = -2

The eigenvalues are repeated real numbers.

3. Matrix C:

[-9  -2]

[-4   3]

Solving the characteristic equation, we find the eigenvalues:

λ₁ ≈ -5.928

λ₂ ≈ -5.072

The eigenvalues are distinct real numbers.

4. Matrix D:

[-2 -9]

The only entry of this matrix corresponds to a single eigenvalue:

λ = -2

The eigenvalue is a distinct real number.

The length of SQ in triangle QRS is approximately 19.8 feet to the nearest tenth of a foot.

To find the length of SQ in triangle QRS, where angle S = 90°, angle Q = 6°, and RS = 20 feet, we can use the sine function. Here's a step-by-step explanation:

1. Identify the given information: In triangle QRS, we have angle S = 90°, angle Q = 6°, and side RS = 20 feet.

2. Since the sum of angles in a triangle is always 180°, we can find angle R: angle R = 180° - angle S - angle Q = 180° - 90° - 6° = 84°.

3. Now we can use the sine function to find the length of side SQ. Since we know angle R and side RS, we can use the sine of angle R to relate side SQ to side RS:

\(sin(angle R) = \frac{opposite side (SQ)}{ hypotenuse side (RS)}\)
\(sin(84°) =\frac{SQ}{20 feet}\)

4. Solve for SQ: \(SQ = (20 feet)  sin(84°) = 19.8 feet.\).

So, the length of SQ in triangle QRS is approximately 19.8 feet to the nearest tenth of a foot.

The function has an inverse that is also a function is g(x)=2x-3

A function that can turn into another function is known as an inverse function or anti function. In other terms, the inverse of a function "f" will take y to x if any function "f" takes x to y. The inverse function is designated by f⁻¹ or F⁻¹ if the function is written by f or F. Here, (-1) should not be confused with an exponent or an inverse.

A function takes in values, applies specific procedures to them, and produces an output. The inverse function works, agrees with the outcome, and returns to the initial function.

The solution in which x and y have been reversed is known as an inverse function.

The vertical line test determines whether a function succeeds or fails when you solve for y once more.

1. Here g(x) = 2x - 3 has inverse x = 2y - 3 which simplifies to;

\(y=\frac{x-3}{2}\)

This is a line and is a function;

\(y=\frac{x}{2} +\frac{1}{2}\)

2. k(x) = -9x² has the inverse x = -9y² which simplifies to;

\(y=\sqrt{x/(-9)}\)

This is a function but only for certain values of x.

3. f(x) = |x+2| is an absolute value function.

Not all absolute value functions have function-based inverses.

4. A function's inverse does not exist for the equation w(x) = -20.

The function therefore has a negative that is also a function, which is

g(x)= 2x – 3.

The tensions in each side of the rope will be the same when Nellie Newton hangs at rest in the middle of a clothesline and the lengths of each rope are the same.

When Nellie Newton is in equilibrium, meaning she is at rest and not experiencing any acceleration or movement, the forces acting on her must be balanced. In the case of a clothesline, the tension in each side of the rope contributes to the balancing of forces.

For the tensions to be the same in each side of the rope, the lengths of the ropes must also be the same. This ensures that the forces applied to each side are equal and balanced, resulting in Nellie Newton remaining in a stable position without any net force acting on her.

Answer:

D) 156/100 = n/70

Step-by-step explanation:

n = 156% of 70

% indicates a fraction over 100.

"of" indicates multiplication.

n = 156/100 • 70

Let's divide both sides by 70 to have one fraction one each side.

n/70 = 156/100

This is equal to D) \((\frac{156}{100}) = (\frac{n}{70})\)

(a) To find AB, perform matrix multiplication of matrices A and B.

(b)  It is not possible to find BA because the number of columns in matrix A does not match the number of rows in matrix B.

(e)  To find the determinant of matrix A, evaluate the determinant using the provided matrix.

4. To find 3A + 2B, perform scalar multiplication and matrix addition using matrices A and B.

(a)Matrix A:

A = |1 -13|

      |0   6|

      |9   2|

Matrix B:

B = |6 -5|

      |10  1|

Performing matrix multiplication:

AB = |(1 * 6) + (-13 * 10)  (1 * -5) + (-13 * 1)|

       |(0 * 6) + (6 * 10)     (0 * -5) + (6 * 1)|

       |(9 * 6) + (2 * 10)     (9 * -5) + (2 * -7)|

Simplifying the multiplication:

AB = |-124 -18|

       | 60   -5|

       | 76  -53|

Therefore, AB = |-124 -18|

                       | 60   -5|

                       | 76  -53|

(b)Matrix A has 2 columns and matrix B has 3 rows. For matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix. Since the dimensions do not match (2 columns vs. 3 rows), we cannot find the product BA.

(e)Matrix A:

A = |0 -1|

      |6  2|

      |5 -1|

Using the formula for a 2x2 matrix determinant:

det(A) = (0 * 2) - (-1 * 6)

            = 0 + 6

            = 6

Therefore, the determinant of matrix A, det(A), is 6.

4.Matrix A:

A = |0 -1|

      |6  2|

      |5 -1|

Matrix B:

B = |0 -3|

      |0 -7|

      |5 -1|

Performing scalar multiplication and matrix addition:

3A = |3 * 0  3 * -1| = |0  -3|

        |3 * 6  3 * 2|     |18   6|

        |3 * 5  3 * -1|     |15  -3|

2B = |2 * 0  2 * -3| = |0  -6|

        |2 * 0  2 * -7|     |0 -14|

        |2 * 5  2 * -1|     |10  -2|

Adding 3A and 2B:

3A + 2B = |0  -3| + |0  -6| = |0  -9|

              |18   6|     |0 -14|     |18 -8|

              |15  -3|     |10  -2|     |25  -5|

Therefore, 3A + 2B = |0  -9|

If the center of the circle is at the origin,

then the coordinates of the center are (0, 0), and the equation can be written as x² + y² = 10². This equation represents a circle with center at the origin and radius 10. This equation can be used to graph the circle by plotting the points that satisfy the equation.

The circle will be a perfect circle with a radius of 10 units and centered at the origin. It will pass through the points (-10, 0), (0, -10), (10, 0), and (0, 10). These points can be found by solving the equation for x and y. When x = -10, 0, and 10, y will be equal to 0, and when y = -10, 0, and 10, x will be equal to 0.

A z-score of 0 means that the sample proportion is equal to the population proportion. Therefore, after using sampling distribution we can conclude that we agree with Aiden's expectation that the percentage for this sample will be 45%.

Based on the given information, we can assume that the population proportion of students who brought a can of food to contribute to the canned food drive is 0.45. Aiden picks a representative sample of 25 students, and he expects the percentage for this sample will be 45%.

We can use the sampling distribution formula to calculate the expected sample proportion:

SE = sqrt[p(1-p) / n]

where p is the population proportion, n is the sample size, and SE is the standard error.

Plugging in the values, we get:

SE = sqrt[0.45(1-0.45) / 25] = 0.0984

Next, we can use the normal distribution to find the z-score corresponding to a sample proportion of 0.45:

z = (0.45 - 0.45) / 0.0984 = 0

A z-score of 0 means that the sample proportion is equal to the population proportion. Therefore, we can conclude that we agree with Aiden's expectation that the percentage for this sample will be 45%.

The horizontal distance between the base of the ladder and the wall is approximately 8.892 feet.

Here, we have,

To find the horizontal distance between the base of the ladder and the wall, we can use trigonometric functions.

In this case, the ladder forms an angle of 69 degrees with the ground. We can label this angle as θ.

We know the length of the ladder is 26 feet. We can label the horizontal distance as x.

Using trigonometric functions, specifically cosine, we have:

cos(θ) = adjacent/hypotenuse

cos(69) = x/26

To find x, we can rearrange the equation:

x = 26 * cos(69)

Using a calculator, we can calculate:

x ≈ 26 * 0.3420

x ≈ 8.892

Therefore, the horizontal distance between the base of the ladder and the wall is approximately 8.892 feet.
