When is the absolute value of a difference equal to the difference of the absolue values?

The absolute value of a difference is equal to the difference of the absolute values when both values have the same sign. This means that if ( a ) and ( b ) are two real numbers, the equation ( |a - b| = |a| - |b| ) holds true if both ( a ) and ( b ) are non-negative or both are non-positive. In other cases, this equality does not hold.

Factoring a linear equation?

Factoring a linear equation typically involves expressing it in the form (y = mx + b) as a product of its components. However, linear equations are generally not factored like polynomials since they represent straight lines. Instead, you can rearrange or rewrite them to isolate variables or simplify expressions, but true factoring applies more to quadratic or higher-degree polynomials. For example, the equation (2x + 4 = 0) can be rewritten as (2(x + 2) = 0), showcasing a basic factorization approach.

How do you calculate 25 plus 8x equals 65?

To solve the equation (25 + 8x = 65), first subtract 25 from both sides to isolate the term with (x): (8x = 65 - 25), which simplifies to (8x = 40). Next, divide both sides by 8 to solve for (x): (x = \frac{40}{8}). This gives you (x = 5).

What is the height and radius of a cylinder if the volume is 512?

Volume(Cyl) = pi r^(2) h

Volume = 512 units^(3)

Then 512 units^(3) = pi r^(2) h

pi = 3.1416

Then

512 / 3.1416 = r^(2) h

From this point you need to komnw either the radius/diameter or the height. Otherwise you cannot proceed.

What are 2 different pairs of negative integers x and y that make the statement x minus y equals 2 true?

Two pairs of negative integers that satisfy the equation ( x - y = 2 ) are ( (-1, -3) ) and ( (-2, -4) ). In the first pair, (-1 - (-3) = -1 + 3 = 2), and in the second pair, (-2 - (-4) = -2 + 4 = 2). Both pairs demonstrate the condition with negative integers.

What is the area of a circle with a diameter of 30m?

The formula for area of a circle is Pi x r (squared), A = Pi(rxr). So since the diameter is 30 you divide it by two and get 15 and then square it and multiply it by pi and get 706.86 meters.

Can a point on a coordinate plane be represented by more than one ordered pair?

No, a point on a coordinate plane can be represented by only one ordered pair. Each point corresponds uniquely to a specific pair of coordinates (x, y), where 'x' indicates its horizontal position and 'y' indicates its vertical position. While different points can share the same x or y values, each distinct point has a unique combination of these coordinates.

What does the equation provide?

The equation provides a mathematical relationship between variables, allowing us to quantify and analyze how changes in one variable affect another. It serves as a tool for problem-solving and can be used to predict outcomes or model real-world phenomena. By understanding the equation, we can derive insights and make informed decisions based on the relationships it describes.

What is the equivalent expression form 5 to the third power?

The expression for 5 to the third power can be written as (5^3). This is equivalent to multiplying 5 by itself three times: (5 \times 5 \times 5). The result is (125).

During what phase of DMAIC is sole purpose to demonstrate with fact and data that your solutions solve the problem?

The phase of DMAIC focused on demonstrating with facts and data that your solutions solve the problem is the "Improve" phase. In this stage, teams implement the identified solutions and collect data to assess their effectiveness. The goal is to ensure that the improvements lead to measurable results and address the root causes of the problem. This phase emphasizes validating the solutions through experimentation and analysis.

What type of function has a graph with a series of unconnected points?

A function that has a graph with a series of unconnected points is typically a discrete function. Discrete functions are defined only for specific values in their domain, rather than over a continuous range. This results in individual points on the graph, rather than a continuous line. Examples include functions that describe situations in which only certain values are possible, such as counting objects or measuring specific events.

What are the intercepts of 7x plus 2y - 14z equals 56?

To find the intercepts of the equation (7x + 2y - 14z = 56), we determine where the equation intersects the axes.

  1. For the x-intercept, set (y = 0) and (z = 0):
    (7x = 56 \Rightarrow x = 8), so the x-intercept is ((8, 0, 0)).

  2. For the y-intercept, set (x = 0) and (z = 0):
    (2y = 56 \Rightarrow y = 28), so the y-intercept is ((0, 28, 0)).

  3. For the z-intercept, set (x = 0) and (y = 0):
    (-14z = 56 \Rightarrow z = -4), so the z-intercept is ((0, 0, -4)).

Thus, the intercepts are ((8, 0, 0)), ((0, 28, 0)), and ((0, 0, -4)).

P(x) 1460000 plus 168600x - 27000x2 What does the constant of polynomial P(x) represent?

In the polynomial ( P(x) = 1460000 + 168600x - 27000x^2 ), the constant term ( 1460000 ) represents the value of the polynomial when ( x = 0 ). This means that it is the y-intercept of the graph of the polynomial, indicating the output value when no input variable (x) is present. In a broader context, it can signify a fixed quantity or starting point in the context of the problem the polynomial is modeling.

What is the measure of the third angle of a triangle if one angle measures 50 degrees and the other measures 105 degrees?

For ALL triangles drawn in a 2-dimensional plain , the sum of the interior angles if ALWAYS 180 degrees.

So for a triangle of 105 + 55 + X = 180

Hence

160 + X = 180

X = 20 The answer !!!!

NB For triangles drawn across the surface of a sphere ( the Earth) , 3-dimension, then the sum of the interior angles may be GREATER than 180 degrees.

Does an obtuse triangle have to be scalene?

NO!!!

Obtuse Isosceles triangle may havw angles of 120 + 30 + 30 = 180

What is time line graphing and how may it be applied to the problem solving process?

Timeline graphing is a visual representation that displays events or data points along a linear scale, allowing for easy identification of patterns, trends, and relationships over time. In the problem-solving process, it can be applied to track the progression of events leading to a problem, analyze historical data to identify causes, and predict future outcomes based on past trends. By organizing information chronologically, timeline graphing helps clarify complex situations and facilitates informed decision-making. This approach enhances understanding and communication among stakeholders involved in the problem-solving process.

What general rules apply to multiplying and dividing exponents?

When multiplying exponents with the same base, you add the exponents (a^m × a^n = a^(m+n)). Conversely, when dividing exponents with the same base, you subtract the exponents (a^m ÷ a^n = a^(m-n)). If raising a power to another power, you multiply the exponents ( (a^m)^n = a^(m*n) ). Finally, for any non-zero base raised to the power of zero, the result is always one (a^0 = 1).

What is a peicewise function?

A piecewise function is a function defined by different expressions or formulas for different intervals or segments of its domain. Each segment is typically specified for a certain condition or range of input values. This allows the function to have distinct behaviors or values depending on the input. For example, a piecewise function might define one formula for ( x < 0 ) and another for ( x \geq 0 ).

What is the algebraic expression for three less than an unknown number?

The algebraic expression for three less than an unknown number, typically represented as ( x ), is ( x - 3 ). This expression indicates that you subtract 3 from the unknown number ( x ).

What is the function of chromath?

Chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells. Its primary function is to package DNA into a more compact, dense structure, allowing for efficient storage and organization of genetic material. Chromatin also plays a crucial role in regulating gene expression and DNA replication, as its structure can change to either condense or relax, facilitating access to specific DNA sequences. Additionally, it helps protect DNA from damage and ensures proper segregation during cell division.
