Step-by-step explanation:

Commutative Property of Addition states that a change in the order of terms does not change your sum.

The given statement is example of the commutative property of addition. So, option A is the correct answer.

According to the commutative property of addition, changing the order of addends has no impact on the sum.

The given statement is x+y=y+x.

Only addition and multiplication operations are under the scope of the commutative property. As a result, it means that while adding or multiplying any two integers, we can swap the positions of the numbers.

Example, 3+8=8+3

⇒ 11=11

So, x+y is same as y+x

Therefore, option A is the correct answer.

A fraction simply means a piece of a whole. In this situation, the number is represented as a quotient such that the numerator and denominator are split. In this situation, in a simple fraction, the numerator as well as the denominator are both integers.

It should be noted that in order to add the numbers it's essential to have a common denominator. For example, 7/8 + 13/16 will be:

= 7/8 + 13/16

= 14/16 + 13/16

To find the magnitude and direction of a vector using trigonometry, you can follow these steps:

1. Identify the components of the vector: A vector can be represented by its horizontal (x) and vertical (y) components. For example, if we have a vector A with components Ax and Ay, we can express it as A = (Ax, Ay).

2. Calculate the magnitude of the vector: The magnitude of a vector is the length of the vector. To find the magnitude of a vector A, you can use the Pythagorean theorem. The formula is:
  magnitude(A) = √(Ax^2 + Ay^2)

3. Find the direction of the vector: The direction of a vector can be given in different forms, such as angles or degrees. Two common ways to express the direction of a vector are:
  a. Angle with the positive x-axis: This angle is measured counterclockwise from the positive x-axis to the vector. You can use trigonometric functions to find this angle. The formula is:
     angle = arctan(Ay / Ax)
  b. Angle with the positive y-axis: This angle is measured counterclockwise from the positive y-axis to the vector. To find this angle, you can subtract the angle obtained in step 3a from 90 degrees (or π/2 radians).

4. Convert the direction to degrees or radians, depending on the required format.

Let's consider an example to illustrate these steps:

Suppose we have a vector A with components Ax = 3 and Ay = 4.

1. Identify the components: A = (3, 4).

2. Calculate the magnitude:
  magnitude(A) = √(3^2 + 4^2) = √(9 + 16) = √25 = 5.

3. Find the direction:
  angle = arctan(4 / 3) ≈ 53.13 degrees.

4. Convert the direction:
  angle with positive y-axis = 90 degrees - 53.13 degrees ≈ 36.87 degrees.

So, the magnitude of vector A is 5, and its direction is approximately 36.87 degrees with a positive y-axis.

Remember, trigonometry can be used to find the magnitude and direction of a vector when you have its components.

The time period in years T = 4 years

The simple interest amount = $252

The rate of interest per year as percentage  = 7%

The principal amount = $900

The simple interest I = PTR

Where I is the interest amount

P is the principal Amount

T is the time period involved in years

R is the rate of interest per year as a percent

Substitute the values in the equation

252 = 900 × T × (7 / 100)

252 = 900 × T × 0.07

252 = 63 × T

Move the 63 to other side

T = 252 / 63

T = 4 years

Hence, the time period in years T = 4 years

The triangle in the picture is an isoceles triangle in which the measure of top vertex angle is given and one of the base angles is also given.

According to angle sum property of triangle , sum of measure of all the angles of traingle is 180°. Also, in isosceles triangle , the base angles are always equal to each other .

So,

\(34 + (x + 79) + (x + 79) = 180\)

\( = > 2x + 158 + 34 = 180\)

\( = > 2x +192 = 180\)

\( = > 2x = 18 0 - 192 = - 12\)

\( = > x = \frac{12}{ - 2} = - 6\)

No, f (x) =9x^4+8x^3-6x^-2+2x is not a polynomial function.

We can define the polynomial function that are expressed in the form of polynomial. it must involves only non-negative integer powers or only positive integer exponents. The highest power of polynomial function is known as its degree. Domain of polynomial function is entire real numbers(R).

P(x) =\(a_{n}\) \(x^{n}\)  + \(a_{n-1}\) \(x^{n-1}\)+.……….…+\(a_{2}\)\(x^{2}\) +\(a_{1}x\) +\(a_{0}\),

The magnitude of Jack’s debt in dollars is $25.50.

The magnitude of an amount is calculated by subtracting the amount from zero.

In this case, Jack has -$25.50 in his bank account.

Hence, the magnitude of his debt can be calculated as follows:

0 – (-25.50) = $25.50.

The term magnitude is defined as the amount or quantity of a particular object that is present. It can vary from situation to situation such as it can be used to explain the distance travelled by a particular moving object from its start point to its end point. Basically, magnitude gives us the size or amount varying on the quantity that is being measured.

The researcher's reasoning is not entirely valid. There is a statistically significant difference between the treatment and control groups, it does not necessarily mean that wearing earplugs will reduce the chance of hearing loss.

A statistically significant result means that the observed difference between the treatment and control groups is unlikely to have occurred by chance alone, but it does not imply a causal relationship. There could be other factors that contributed to the difference observed, such as differences in age, exposure to noise, or other environmental factors.

To establish a causal relationship between wearing earplugs and reducing the chance of hearing loss, a randomized controlled trial (RCT) is needed.

The reasoning is not entirely valid. While a p-value less than the significance level of 5% suggests that there is a statistically significant difference between the treatment and control groups, it does not necessarily mean that wearing earplugs will reduce the chance of hearing loss.

First we know about -

Divisor: The number by which the dividend is divided.

Quotient: The result of division.

Remainder: The amount that is left over after division.

Rules for the Division -

1. Take the first digits of the dividend, the same number of digits that the divisor has. If the number taken from the dividend is smaller than the divisor, you need to take the next digit of the dividend.

2. Divide the first number of the dividend (or the two first numbers if the previous step took another digit) by the first digit of the divisor. Write the result of this division in the space of the quotient.

3. Multiply the digit of the quotient by the divisor, write the result beneath the dividend and subtract it. If you cannot, because the dividend is smaller, you will have to choose a smaller number in the quotient until it can subtract.

4. After subtraction, drop the next digit of the dividend and repeat from step 2 until there are no more remaining numbers in the dividend.

we need to find out the amount of work required to stretch the spring from x=0 to x=2 m. Work is defined as the amount of energy expended when a force is applied to an object to move it.

To calculate the work required to stretch the nonlinear spring from x=0 to x=2 m, we need to find the force at each position and calculate the distance traveled.

Finding the force at each position:

When \(x = 0, F = 20(0) - (0)3 = 0\) N

When \(x = 2 m, F = 20(2) - (2)3 = 36 N\)

To find the work done, we need to calculate the area under the force-distance curve.

Since the force is changing with displacement, we can't use the simple formula of W=Fd, we need to integrate the force with respect to displacement.

\(W = ∫ Fdx (from x=0 to x=2)W = ∫(20x - x^3)dx (from x=0 to x=2)W = [(10x^2 - x^4)/2] (from x=0 to x=2)W = [(10(2)^2 - (2)^4)/2] - [(10(0)^2 - (0)^4)/2]W = 20 - 0W = 20 Joules\)
