Properties of determinants are Reflection Property, Reliable scales Property, Scalar Multiple Property, Switching Property and All-zero Property.

1. Reflection Property: The determinant remains unchanged when its columns turn into rows and vice versa. The reflection property is what is used to describe this.

2. If every element in a row (or column) is zero, the determinant is zero, according to the all-zero property.

3. Reliable scales (Repetition) Property: If every element in a row or column is proportional to or identical to every element in another row, the determinant is zero (or column).

4. When any two of the determinant's rows (or columns) are exchanged, the sign of the determinant changes.

5. Scalar Multiple Property: If all of a determinant's components in a row (or column) are multiplied by a non-zero constant, the determinant is multiplied by that constant.

6. Factor Property: If a determinant Δ becomes zero when we put x = α, then (x – α) is a factor of Δ.

Hence this is all about determinants problems.

Answer:D. The answer is 3.

Step-by-step explanation:

The probability of Alice, Bob, and Cicily sitting together with Alice to the left of Bob and Cicily to the right of Bob is 2 × 3! / (n-1)!

To find the probability that Alice, Bob, and Cicily sit together at a table with Alice to the left of Bob and Cicily to the right of Bob, consider them as a single entity. Let's denote this entity as ABC.

(n-1) entities since ABC is considered as one. The total number of ways to arrange (n-1) entities is (n-1)!.

Within the ABC entity, Alice, Bob, and Cicily  arrange themselves in 3! = 6 different ways.

Since Alice can sit to the left of Bob and Cicily to the right of Bob, there are two valid arrangements: ABC and ACB.

The specific range depends on the material properties and the energy levels involved.

The minimum and maximum frequencies for the acoustic and optic modes depend on the specific system or material under consideration. However, I can provide some general information.

Acoustic Mode:

The acoustic mode refers to the propagation of sound waves or vibrations in a material. In a solid, the acoustic mode can have different types, such as longitudinal and transverse modes.

The minimum frequency for the acoustic mode is typically determined by the size and physical properties of the material. In general, it can be close to zero for macroscopic objects or materials with low elasticity.

The maximum frequency for the acoustic mode depends on factors such as the speed of sound in the material and the characteristic dimensions of the system. It can range from a few kilohertz to several gigahertz.

Optic Mode:

The optic mode is related to the interaction of light with a material. It typically refers to the vibrations of charged particles (such as electrons) in a solid or the oscillations of electric or magnetic fields associated with photons.

The minimum frequency for the optic mode is typically determined by the energy gap between electronic states in the material. For example, in a semiconductor, the minimum frequency is usually in the infrared range.

The maximum frequency for the optic mode is not strictly defined, as it can extend into the terahertz, infrared, visible, ultraviolet, X-ray, and even gamma-ray regions. The specific range depends on the material properties and the energy levels involved.

It's important to note that these frequency ranges are general guidelines and can vary depending on the specific system or material being studied.

The value of the quotient of the polynomial is 2x^2 + 2x + 10 and the remainder is 28

A method for solving a rational number that represents a polynomial divided by a monomial or another polynomial is called "dividing polynomials." In order to divide normally, we place the dividend and the divisor in the exact same manner.

Divide the first term of the dividend by the highest term of the divisor, which in this case is x (i.e., the term with the highest power of x).

Divide the divisor by the outcome you just got (the first term of the eventual quotient).

By following the above rules where

2x3-4x2+3x+2 is divided by the x-3, We get the following equation

where

quotient is 2x2+2x+10

Therefore, according to the squeeze theorem, the limit of x^2 cos(1/x^2) as x approaches 0 is also 0: lim(x→0) x^2 cos(1/x^2) = 0.

To prove that lim(x→0) x^2 cos(1/x^2) = 0, we can use the squeeze theorem.

First, we establish the following inequalities:

-1 ≤ cos(1/x^2) ≤ 1

Since -1 ≤ cos(1/x^2) ≤ 1 for all values of x, we can multiply each side of the inequality by x^2 to obtain:

-x^2 ≤ x^2 cos(1/x^2) ≤ x^2

Now, we need to evaluate the limits of the lower and upper bounds as x approaches 0:

lim(x→0) -x^2 = 0

lim(x→0) x^2 = 0

Since both lower and upper bounds approach 0 as x approaches 0, we can conclude that the function x^2 cos(1/x^2) is "squeezed" between these two functions.

Thus, the statement is proven.

S₁ = (ln √2 - ln √1)

   = ln √2

S₂ = (ln √3 - ln √2) + (ln √2 - ln √1)

   = ln √3 - ln √1

S₃= (ln √4 - ln √3) + (ln √3 - ln √2) + (ln √2 - ln √1)

(a) The approximated root of f(x) = e^x + x^2 - x - 4 is x ≈ 2.151586.

(b) The approximated root of f(x) = x^3 - x^2 - 10x + 7 is x ≈ -0.662460.

(c) The approximated root of f(x) = 1.05 - 1.04x + ln(x) is x ≈ -1.240567.

(a) Purpose: f(x) = ex + x2 - x - 4 To apply Newton's method, we must determine the function's derivative as follows: f'(x) = e^x + 2x - 1.

Now, we can use the formula to iterate: Choose an initial guess, x(0) = 0, and carry out the iterations as follows: x(n+1) = x(n) - f(x(n))/f'(x(n)).

1. Iteration:

Iteration 2: x(1) = 0 - (e0 + 02 - 0 - 4) / (e0 + 2*0 - 1) = -4 / (-1) = 4.

(b) Capability: f(x) = x3 - x2 - 10x + 7 The function's derivative is as follows: f'(x) = 3x^2 - 2x - 10.

Let's apply Newton's method with an initial guess of x(0) = 0:

You can solve this equation in two ways.

1) Count the ratio of rise to run:

You're going up 4 spaces and going to the left three spaces. Therefore, the slope would be 4/3. It would also be positive because it's going up. Think of it like going up a mountain.

2) The second way is by using the formula:

y2-y1/x2-x1

Then fit in the missing digits.

-3-1= -4 and -3-0= -3. Since both numbers are negative and a negative divided by a negative is a positive number, your answer would be a positive 4/3.

The researcher with the interval from 3.89 to 4.09 likely had a smaller sample size.

The confidence interval is a measure of the reliability of an estimate. It is calculated by taking the mean of the sample and adding and subtracting a margin of error. The margin of error is calculated by multiplying the standard error of the mean (SEM) by the appropriate z-score from the normal distribution. Thus, the formula for the confidence interval is: \(CI = mean +/- (z-score * SEM).\)

The researcher with the interval from 3.89 to 4.09 likely had a smaller sample size because their margin of error is smaller than the researcher with the interval from 3.89 to 4.29. This is because the z-score used in the calculation of the margin of error is smaller for the researcher with the smaller interval. The z-score is a measure of how many standard deviations away from the mean the confidence interval is, and thus the smaller the interval, the smaller the z-score, and the smaller the margin of error. Therefore, the researcher with the interval from 3.89 to 4.09 likely had a smaller sample size.

Rewriting 8 as 2^3

2^p x 2^3^q = 2^n

Using the rule a^b^c = a^(b*c)

2^p x 2^3q = 2^n

Using the rule a^b * a^c = a^(b+c)

2 ^(p+3q) = 2^n

p+3q = n

Answer:

\( \sf \: p + 3q = n\)
