1) Use Product Rule: \(x^ax^b=x^{a+b}\).

\((\frac{3x^{-5+2}{y^3}}{2z^0yx}) ^3\)

2) Use Negative Power Rule: \(x^{-a}=\frac{1}{x^a}\).

\((\frac{3\times\frac{1}{x^3} y^3}{2x^0yx} )^3\)

3) Use Rule of Zero: \(x^0=1\).

\((\frac{\frac{3y^3}{x^3} }{2\times1\times yx} )^3\)

4) use Product Rule: \(x^ax^b=x^{a+b}\).

\((\frac{3y^3}{2x^{3+1}y} )^3\)

5) Use Quotient Rule: \(\frac{x^a}{x^b} =x^{a-b}\).

\((\frac{3y^{3-1}x^{-4}}{2} )^3\)

6) Use Negative Power Rule: \(x^{-a}=\frac{1}{x^a}\).

\((\frac{3y^2\times\frac{1}{x^4} }{2} )^3\)

Answer:

x = 24

Step-by-step explanation:

if a and b are parallel then

62 and 5x - 2 are same- side interior angles and sum to 180° , that is

5x - 2 + 62 = 180

5x + 60 = 180 ( subtract 60 from both sides )

5x = 120 ( divide both sides by 5 )

x = 24

thus for a to be parallel to b , then x = 24

No, it is not reasonable to assume that the wage rate of the ethnic group is equivalent to that of a random sample of workers from those employed in the service industry.

What is standard deviations?
Standard deviation is a measure of how spread out a set of data is. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean. Standard deviation is a measure of how much the individual observations in a data set vary from the mean. A low standard deviation indicates that most of the values are very close to the mean, while a high standard deviation indicates that the values are more spread out.

The average wage of the ethnic group is only $6.90 per hour, which is significantly lower than the average wage of $7.00 per hour for the entire industry. Even though the standard deviation of the industry is $.50, this does not account for the difference in wages between the ethnic group and the rest of the industry. Therefore, it is not reasonable to assume that the wage rate of the ethnic group is equivalent to that of a random sample of workers from those employed in the service industry.

The acceleration vector can be written as a = (25/9)T + 0N, or simply a = (25)T. (option a).

To find the acceleration, we need to take the second derivative of the position vector r(t) with respect to time, which represents the rate of change of velocity. Let's start by finding the first derivative of r(t):

r'(t) = (d/dt)(9sin(5t/9) + 2)i + (d/dt)(9cos(5t/9) - 7)j + (d/dt)(12t)k

The unit tangent vector T is defined as the normalized version of the velocity vector, which is r'(t)/||r'(t)||. To find T, we calculate the magnitude of r'(t) and normalize it:

||r'(t)|| = √((25/9)²(sin²(5t/9) + cos²(5t/9))) = √((25/9)²) = 25/9

Therefore, the unit tangent vector T is given by:

T = r'(t) / ||r'(t)|| = [(25/9)(-sin(5t/9))i - (25/9)(cos(5t/9))j] / (25/9) = (-sin(5t/9))i - (cos(5t/9))j

The unit normal vector N is perpendicular to the unit tangent vector T and is given by N = (cos(5t/9))i - (-sin(5t/9))j, or simplifying it, N = (cos(5t/9))i + (sin(5t/9))j.

Now, we can express the acceleration vector in the form atT + anN by taking the dot product of r''(t) with T and N:

aT = r''(t) · T = (25/9)(-sin(5t/9))(-sin(5t/9)) + (25/9)(cos(5t/9))(-cos(5t/9)) = 25/9

aN = r''(t) · N = (25/9)(-sin(5t/9))(cos(5t/9)) + (25/9)(cos(5t/9))(sin(5t/9)) = 0

Therefore, the correct answer is: A) a = 25T

By answering the question the answer is Therefore, landscapers should equation use 35 gallons of an 80% pesticide solution.

In mathematics, an equation is a statement that two expressions are equal. The equation consists of her two sides divided by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the statement "2x + 3" equals the value "9". The goal of solving an equation is to find the values ​​of the variables to make the equation true. Simple or complex equations, regular or nonlinear, and equations involving one or more factors are all possible. For example, the expression "\(x2 + 2x - 3 = 0\\\)" squares the variable x. Lines are used in many areas of mathematics, including algebra, calculus, and geometry.  

Let's say a landscaper needs to use x gallons of an 80% pesticide solution.

The amount of pesticide for an 80% solution is 0.8 x gallons and the amount of pesticide for a 30% solution is 0.3 (35) = 10.5 gallons.

After mixing the two solutions, the total amount of pesticides in the mixture is 0.8 x + 10.5 gallons and the total volume of the mixture is x + 35 gallons.

Since we need a 55% pesticide solution, we can set the following formula:

\(0.8x10.5 0.55(x+35)0.8x10.5 0.55x+19.250.25x = 8.75x = 35\)

Therefore, landscapers should use 35 gallons of an 80% pesticide solution.

we have only one outcome that is neither positive nor negative, then the statement is false.

What is square root?

A value known as the square root of a number is one that, when multiplied by itself, yields the original number. An alternative to square rooting a number is to use it. Therefore, the concepts of squares and square roots are connected. The original number is equal to the square root of any integer, which is equivalent to a number.

Let's assume that m is an integer that is positive, such that (m.m) = (m2) = m.

This seems to be true because:

The matrix must have pivot columns. Otherwise, the equation Ax = 0 would have a free variable, in which case the columns of A would not span R5. Therefore, the correct answer is C.

A pivot column is a column of the matrix that has a non-zero entry in the pivot position and all entries below the pivot are zero. In row echelon form, every row below a pivot column has a zero in the corresponding position. The pivot columns correspond to the linearly independent columns of the original matrix and the number of pivot columns determines the rank of the matrix.

The rank of a matrix is defined as the number of linearly independent columns or rows in the matrix. If the columns of a matrix span Rn, then the rank of the matrix must be equal to n. This means that the matrix must have n linearly independent columns. To ensure that the columns of A span R5, A must have at least 5 pivot columns. If A had fewer pivot columns, then the equation Ax = 0 would have a non-trivial solution, meaning that the columns of A would not be linearly independent and would not span R5.

The probability of passing the exam, given that the lowest passing grade is 6 correct out of 8, is approximately 0.1445 or 14.45%.

To find the probability of passing the exam if the lowest passing grade is 6 correct out of 8, we need to calculate the probability of getting 6, 7, or 8 questions correct.

In an 8-question true-false exam, there are 2 possible outcomes (true or false) for each question. Therefore, the total number of possible outcomes for answering 8 questions is 2^8 = 256.

To determine the number of ways to get exactly 6, 7, or 8 questions correct, we can use combinations. The number of ways to choose k items from a set of n items is given by the combination formula:

C(n, k) = n! / (k! * (n-k)!)

For 6 questions correct:

C(8, 6) = 8! / (6! * (8-6)!) = 28

For 7 questions correct:

C(8, 7) = 8! / (7! * (8-7)!) = 8

For 8 questions correct:

C(8, 8) = 8! / (8! * (8-8)!) = 1

Therefore, there are 28 + 8 + 1 = 37 ways to pass the exam (getting 6, 7, or 8 questions correct).

The probability of passing the exam is the ratio of the number of favorable outcomes (passing) to the total number of possible outcomes:

P(passing) = number of favorable outcomes / total number of possible outcomes

P(passing) = 37 / 256 ≈ 0.1445

So, the probability of passing the exam, given that the lowest passing grade is 6 correct out of 8, is approximately 0.1445 or 14.45%.

Euler's method will be more accurate if the solution to the differential equation is a lower order polynomial. As the order of the polynomial increases, the accuracy of Euler's method decreases.

Euler's method is a numerical approximation technique used to estimate the solution to a differential equation. It is not exact and introduces some error due to its approximation nature.

The accuracy of Euler's method depends on the order of the polynomial that represents the solution.

In general, Euler's method is more accurate for lower order polynomials. This means that if the solution to the differential equation is a lower order polynomial, the approximation obtained using Euler's method will be more accurate.

To understand this, let's consider an example. Suppose we have a first-order polynomial as the solution to the differential equation.

In this case, Euler's method will provide a reasonably accurate approximation. However, as the order of the polynomial increases, the accuracy of Euler's method decreases.

It's important to note that higher order polynomials have more complex behavior, and Euler's method cannot capture all the intricacies of the solution.

In such cases, other numerical approximation methods, like the Runge-Kutta method, may be more suitable.

In summary, Euler's method will be more accurate if the solution to the differential equation is a lower order polynomial. As the order of the polynomial increases, the accuracy of Euler's method decreases.

The total percentage decrease in the investor's stock account is 13.6%

Percentage is a way of expressing a number as a fraction of 100. It is denoted using the symbol "%". For example, 25% is the same as 25/100 or 0.25.

To find the total percentage decrease in the investor's stock account, we need to first calculate the new values of the stocks after the decreases and then find the percentage decrease of the total value compared to the original value.

The new value of the stock in Company A is:

5750 - 0.16 * 5750 = 4830

The new value of the stock in Company B is:

1200 - 0.02 * 1200 = 1176

The total value of the stocks after the decreases is:

4830 + 1176 = 6006

The percentage decrease of the total value compared to the original value is:

(1 - 6006/6950) * 100% = 13.6%

The correct answer is: D. The graph of g(x) is the graph of f(x) shifted to the right 6 units.

In the given function g(x) = f(z - 6), the input variable "z" is being shifted to the right by 6 units. This means that any x-value in the original function f(x) will be replaced with (x - 6) in the function g(x).

Since f(x) is a constant function with a value of 10%, the graph of f(x) is a horizontal line at y = 10%. When we shift the input variable "x" to the right by 6 units in g(x), the horizontal line representing the function f(x) will also shift to the right by the same amount.
