The thickness of the tharsan thir is approximately 0.06 mm when expressed in two decimal places.

To convert micrometers (μm) to millimeters (mm), we need to divide the value in micrometers by 1000 since there are 1000 micrometers in a millimeter.

Given that the thickness is 60 μm, we can perform the conversion as follows:

60 μm / 1000 = 0.06 mm

Therefore, the thickness of the tharsan thir is approximately 0.06 mm when expressed in two decimal places.

Millimeters and micrometers are both units of length, with millimeters being the larger unit. Micrometers are often used to represent very small measurements, such as the thickness of thin materials or microscopic objects. In this case, the tharsan thir has a thickness of 60 micrometers, which is equivalent to 0.06 millimeters.

Converting between micrometers and millimeters is a simple process involving the division by 1000. This conversion is necessary when dealing with different scales or when using units that are more convenient for a specific application.

Answer:

x = 46°

Step-by-step explanation:

Angles on a straight line sum to 180°.

Therefore, the interior angle of the triangle that forms a linear pair with the exterior angle marked 130° is:

⇒ 180° - 130° = 50°

The interior angle of the triangle that forms a linear pair with the exterior angle marked 96° is:

⇒ 180° - 96° = 84°

The interior angles of a triangle sum to 180°. Therefore:

⇒ 50° + 84° + x = 180°

⇒ 134° + x = 180°

⇒ 134° + x - 134° = 180° - 134°

⇒ x = 46°

Therefore, the size of angle x is 46°.

Step-by-step explanation:

To find the radius of a cylindrical can that contains 1728 cm³ of water while using the minimum amount of metal, we need to minimize the surface area of the can.  

The surface area of a cylindrical can is given by the formula A = 2πr² + 2πrh, where r is the radius and h is the height.

We can express the height in terms of the volume and radius by using the formula V = πr²h. Rearranging the formula, we have h = V / (πr²). Substituting this into the surface area equation, we get A = 2πr² + 2πr(V / (πr²)). Simplifying further, A = 2πr² + 2V / r.

To minimize the surface area, we take the derivative of A with respect to r and set it equal to zero. Differentiating and solving for r, we find r = ∛(3V / (4π)). Substituting the given volume of 1728 cm³ into the formula, we get r = ∛(3 * 1728 / (4π)) ≈ 6 cm.

Therefore, the radius of the cylindrical can that contains 1728 cm³ of water while using the minimum amount of metal is approximately 6 cm.

Answer:

Yes, if two random vectors are independent, then after a same transformation they are still independent. This is a consequence of the fact that the transformation of independent random variables does not affect their independence.

To understand this, suppose we have two independent random vectors X and Y, and a transformation function f(.).

If we apply the same transformation f(.) to both X and Y to get f(X) and f(Y), then the independence between X and Y will still hold in the transformed variables f(X) and f(Y).

This is because the transformation f(.) does not introduce any new relationship between the variables, it simply changes their scale or shape. As a result, if X and Y are independent, then f(X) and f(Y) will also be independent.

To find the value of k for which the system of equations has no solution, we need to examine the coefficients of x and y in the equations.

The first paragraph provides a concise summary of the answer, while the second paragraph explains the solution in more detail.

For the system of equations to have no solution, the coefficients of x and y in the equations must be proportional. In other words, the ratios of the coefficients should be equal for both equations. If the coefficients are not proportional, the system will have a unique solution. Therefore, to determine the value of k for which the system has no solution, we need to examine the coefficients of x and y in the equations and find the condition where they are proportional.

In more detail, let's consider the system of equations as:

Equation 1: ax + by = c

Equation 2: dx + ey = f

For the system to have no solution, the ratios of the coefficients a/d and b/e should be equal to each other. In other words, a/d = b/e. Solving this equation will give us the condition for k that results in no solution. The specific values of a, b, d, and e will depend on the given system of equations. By finding the appropriate condition, we can determine the value of k that satisfies this requirement and leads to no solution for the system of equations.

The regular polygon has 18 sides.

To find the number of sides of a regular polygon given the relationship between the measures of its exterior and interior angles, we can set up an equation using the properties of polygons.

Let's assume the measure of each interior angle of the regular polygon is represented by "x" degrees. According to the given information, the measure of each exterior angle is 1/8 times the measure of the interior angle. Therefore, the measure of each exterior angle is (1/8)x degrees.

In any polygon, the sum of all exterior angles is always 360 degrees. Since our regular polygon has "n" sides, the sum of all the exterior angles will be equal to 360 degrees.

We can now set up an equation using the information:

(1/8)x * n = 360

To solve for "n," we can multiply both sides of the equation by 8 to eliminate the fraction:

x * n = 8 * 360

x * n = 2880

Since "x" represents the measure of each interior angle and "n" represents the number of sides, we know that the sum of the interior angles in any polygon is given by the formula (n-2) * 180 degrees.

Therefore, we can set up another equation using this formula:

x * n = (n-2) * 180

Substituting the value of x * n from the previous equation:

2880 = (n-2) * 180

Now, we can solve for "n" by dividing both sides of the equation by 180:

2880/180 = n - 2

16 = n - 2

Adding 2 to both sides:

16 + 2 = n

18 = n

Hence, the regular polygon has 18 sides.

the common factor between 8 and 15 is 3 and 5. If you add 3 and 5 together, you get 8. If you multiply 3 and 5, you get 15. So using the FOIL method, it should go back to n^2+8n+15

Brian deposited $9,808 into a savings account that compounds interest on a daily basis, at a rate of 3.78%. If we want to find out how much interest he will earn after 12 years, we can use the formula:

A = P(1 + r/n)^(nt)

where A is the amount of money after t years, P is the principal amount (which is $9,808 in this case), r is the annual interest rate (3.78% in this case), n is the number of times the interest is compounded per year (which is 365 since it compounds daily), and t is the number of years (which is 12).

So, plugging in the values we get:

A = $9,808(1 + 0.0378/365)^(365*12)

A = $9,808(1.000103972)^4380

A = $9,808(1.496812899)

A = $14,682.54

Therefore, the interest Brian will earn after 12 years is $14,682.54 - $9,808 = $4,874.54. When we round this answer to the hundredths place, we get $4,874.54.

The algebraic representation that shows a dilation that is an enlargement is (5/2 x,5/2 y). (Option D)

A dilation is a type of transformation that changes the size of the shape or object.  It refers to a process of changing an object’s size by decreasing or increasing its dimensions by a scaling factor. A dilation produces an image that has the same shape as the original image but is a different size.

A dilation that results in a larger image is called an enlargement while a dilation that generates a smaller image is called a reduction. A dilation is described using the scale factor and the center of the dilation (which is a fixed point in the plane).

For a scale factor > 1, the image is an enlargement; for a scale factor < 1 and  > 0, the image is a reduction; and for a scale factor = 1, the figure and the image are congruent. Hence, for a point (x,y), algebraic representation that shows a dilation that is an enlargement is (5/2 x,5/2 y) as the scale factor is greater than 1. For the remaining options, the scale factor is between 0 and 1, hence they are reduction.

Note: The question is incomplete. The complete question probably is: Which of the following algebraic representation shows a dilation that is an enlargement? A) (1/3 x,1/3 y) B) (0.1x, 0.1y) C) (5/6 x,5/6 y) D) (5/2 x,5/2 y)

An \( \bar{X} \) chart is NOT used to track a process with binary outcome variables. The statement is false.

Explanation: A process chart is a graphical tool used to monitor processes in production and service industries. The average process performance and the upper and lower limits are calculated and displayed on an X-bar chart, which is a common process chart. The values for a variable can be collected and analyzed using process charts. An \( \bar{X} \) chart, commonly known as an x-bar chart, is used to monitor a process with continuous numerical data. A binary outcome variable, on the other hand, has only two possible outcomes (e.g., yes/no, pass/fail, etc.). As a result, binary data is unsuitable for an \( \bar{X} \) chart, which is only used to monitor continuous numerical data.

Variables are values that may be altered in a process, which can affect its results. Variables may be categorized as continuous or discrete, depending on whether they can be measured or counted. Discrete variables, such as the number of employees working on a task or the number of items produced in a process, are quantifiable and can be measured precisely. Continuous variables, such as the temperature, length, or weight, can take on any value over a range and are therefore less specific. The reasons for holding inventory include serving as a buffer against uncertainties, ensuring product availability and preventing stockouts, reducing lead times and transportation costs, taking advantage of discounts and bulk purchasing opportunities, and providing a hedge against inflation and price fluctuations.

Therefore, the solution to the inequality is: -8 < x ≤ 1 or x = 2. In interval notation, we can write the solution as: (-8, 1] ∪ {2}.

Inequality is a mathematical statement that compares two quantities or expressions and indicates that one is greater than, less than, or not equal to the other. An inequality is typically expressed using symbols such as < (less than), > (greater than), ≤ (less than or equal to), ≥ (greater than or equal to), or ≠ (not equal to).

Here,

Since the function f is increasing, we know that if x₁ < x₂, then ƒ(x₁) < ƒ(x₂). To solve the inequality, we need to isolate x on one side of the inequality. We'll start by applying the function ƒ to both sides of the inequality:

ƒ(4x − 3) ≥ ƒ(2 − x²)

Since ƒ is increasing, we can apply it to each side of the inequality without changing the direction of the inequality:

4x − 3 ≥ 2 − x²

Next, we'll simplify the right side of the inequality by expanding the square:

4x − 3 ≥ 2 + x²

Now we'll move all the terms to one side of the inequality:

x² - 4x + 5 ≤ 0

We can factor the quadratic expression to get:

(x - 2)(x - 2 + 1) ≤ 0

Simplifying further:

(x - 2)(x - 1) ≤ 0

Now we need to determine the sign of the expression (x - 2)(x - 1) over the domain D = (-8, 4). We can do this by using a sign chart:

x x - 2 x - 1 (x - 2)(x - 1)

-8 -10 -9 +90

-1 -3 -2 +2

1 -1 0 0

4 2 3 -6

Answer:

Step-by-step explanation:

If A=[1 0 -1 7] find K such that A^2-8A-ki-KI=0

Given the 2×2 matrices

A = \(\left[\begin{array}{ccc}1&0\\-1&7\\\end{array}\right]\)

We are to find K if  =0

A² =  \(\left[\begin{array}{ccc}1&0\\-1&7\\\end{array}\right]\)\(\left[\begin{array}{ccc}1&0\\-1&7\\\end{array}\right]\)

A² = \(\left[\begin{array}{ccc}1&0\\-8&49\\\end{array}\right]\)

8A = 8\(\left[\begin{array}{ccc}1&0\\-1&7\\\end{array}\right]\)

8A = \(\left[\begin{array}{ccc}8&0\\-8&56\\\end{array}\right]\)

Since \(I = \left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right] \\\)

\(KI = \left[\begin{array}{ccc}K&0\\0&K\\\end{array}\right]\)

Substitute the resulting matrices into the expression above:

A^2-8A-KI =  \(\left[\begin{array}{ccc}1&0\\-8&49\\\end{array}\right]\) - \(\left[\begin{array}{ccc}8&0\\-8&56\\\end{array}\right]\) - \(\left[\begin{array}{ccc}K&0\\0&K\\\end{array}\right]\) =\(\left[\begin{array}{ccc}0&0\\0&0\\\end{array}\right]\)

From the expression, we have the equations;

1 - 8 - k = 0

-7 - k = 0

-7 = k

k = -7

Hence the value of K is -7
