Attributes, properties, or classifications can be used to describe, compare, or classify two-dimensional figures or three-dimensional solids by examining their shape, size, and characteristics.

For example, a triangle and a square are both two-dimensional figures. They can be described by their shape (triangle and square), their number of sides (3 and 4), and their angles (acute, right, or obtuse). They can be compared by examining the same attributes, such as their area, perimeter, and angles. Finally, they can be classified by their shape (both are polygons) or by their number of sides (both are quadrilaterals).

Any feature or trait that identifies a person is considered a personal attribute. This trait suggests that they have something innately good, aspirational, and sensitive about them. Different from skills are attributes. Training can be used to develop skills, which are often taught. Using nonverbal communication as an example, a skill.

Answer: Solution: \(a=\dfrac{-19}{3}\) and \(b=\dfrac{1}{3}\) .

Step-by-step explanation:

The given pair of equations:

\(a-8b= -9\ ...(i)\\\\ a-2b= -7\ ...(ii)\)

Eliminate equation (i) from (ii) , we get

\(-2b-(-8b)=-7-(-9)\\\\\Rightarrow\ -2b+8b=-7+9\\\\\Rightarrow\ 6b=2\\\\\Rightarrow\ b=\dfrac{1}{3}\)

Put value of b in (ii) , we get

\(a-2\times\dfrac{1}{3}=-7\\\\\Rightarrow\ a=-7+\dfrac{2}{3}\\\\\Rightarrow\ a=\dfrac{-21+2}{3}\\\\\Rightarrow\ a=\dfrac{-19}{3}\)

Solution: \(a=\dfrac{-19}{3}\) and \(b=\dfrac{1}{3}\) .

The equation that can be used to calculate how many minutes after 4:00 p.m. she will arrive at her location is y = 4x - 16.

The correct equation is:

y = 4x - 16

This equation represents the number of minutes after 4:00 p.m. the pilot will arrive at her destination. The variable x represents the time, in minutes, of her original flight, and y represents the number of minutes after 4:00 p.m. she will arrive at her destination. The expression "4x" represents the time the pilot will arrive at her destination if she had traveled at her original speed, and the "-16" represents the delay caused by air traffic.

To solve this equation, you would substitute the value of x into the equation and solve for y. For example, if the pilot's original flight time was 60 minutes, the equation would be:

y = 4(60) - 16

= 240 - 16

= 224

This means that the pilot will arrive 224 minutes after 4:00 p.m., or at 6:24 p.m.

The limit definition of a derivative is a mathematical method used to calculate the instant rate of change of a characteristic at a particular point. it is based at the idea of the limit of a function because the input techniques a certain cost.

The limit definition of a derivative is expressed as follows:

\(f'(x) = lim (h → 0) [f(x + h) - f(x)] /h\)

Wherein f'(x) represents the derivative of the function f(x) at a particular factor x. The expression \(( f(x + h) - f(x)) / h\) represents the common price of alternate of the characteristic over a small interval of size h, focused at x. The limit of this expression as h approaches 0 represents the instant fee of change of the characteristic at x, or the slope of the tangent line to the function at that factor.

The limit definition of a derivative is a fundamental concept in calculus and is used to calculate the slopes of tangent lines, to find maximum and minimum factors, and to clear up optimization issues in a huge variety of packages.

The graph of y = ∛(x - 3) is a horizontal translation of the graph of y = ∛x by 3 units to the right.

To determine the graph of y = ∛(x - 3), let's analyze the transformation that has occurred compared to the original function y = ∛x.

Start with the original function y = ∛x, which represents the cube root of x. This function has a vertical shift of 0 and is symmetric about the origin.

The transformation y = ∛(x - 3) indicates a horizontal translation of the graph of y = ∛x. The expression (x - 3) inside the cube root implies a shift of 3 units to the right.

As a result, the graph of y = ∛(x - 3) will have the same shape and characteristics as the graph of y = ∛x but shifted 3 units to the right.

The new graph will intersect the y-axis at the point (3, 0), indicating the translation to the right.

Any other point on the original graph will also be shifted 3 units to the right on the new graph.

The new graph will remain symmetric about the origin and retain the same increasing or decreasing behavior as the original function.

Therefore, the graph of y = ∛(x - 3) is a horizontal translation of the graph of y = ∛x by 3 units to the right.

Technically efficient, is what pizza parlor is but not allocatively efficient nor economically efficient

What is meant by Technical efficiency? Give an example.

The effectiveness with which a several  set of inputs is employed to generate an output is called as technical efficiency. Technical efficiency refers to a company's ability to generate the highest amount of output from the least amount of inputs, such as labor, capital, and technology.

Technical effectiveness eliminates the wants  for resource unemployment.

Consider the following example : Using its present staff and robot count, a company manufactures 300 automobiles every week. if 320 was the highest possible output.

The company's technical efficiency rate is (300/320) = 93.75%.

In this example , certain employees and factor inputs are underutilized, and some potential production is lost.

Answer:

Perimeter of the park = 70 cm

Step-by-step explanation:

Perimeter of the park = perimeter of the 2 semicircles + 2(length of the rectangle)

Perimeter = 2πr + 2(BC)

✔️Perimeter of the 2 semicircles = 2πr

Where,

radius (r) = ½(AB) = ½(7)

r = 3.5 cm

Perimeter = 2*π*3.5 = 7*π

Perimeter of the two semicircles = 21.9911486 ≈ 22 cm

✔️Find BC using Pythagorean theorem:

Thus,

BC = √(AC² - AB²)

AC = 25

AB = 7

BC = √(25² - 7²) = √576

BC = 24

✔️Perimeter of the park = perimeter of the 2 semicircles + 2(length of the rectangle)

Perimeter of the park = 22 + 2(24)

= 22 + 48

= 70 cm

In line, the ratio of change in y to change in x is called slope of line.

The slope represents the steepness or inclination of the line and indicates how much the y-coordinate changes for a given change in the x-coordinate.

It is calculated by dividing the change in y (vertical distance) by the change in x (horizontal distance) between any two points on the line.

The slope can be positive, negative, or zero, reflecting whether the line is ascending, descending, or horizontal, respectively. The slope is a concept in algebra and geometry and plays important role in analyzing and describing linear-relationships.

Answer:

9 weeks

Step-by-step explanation:

edge 2020

On solving the inequality, 9 weeks of exercise are necessary to lower the individual’s resting heart rate below 70 beats per minute.

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

\(-0.1x^{3} + 0.6x^{2} +85 < 70\\\)

where, x is the number of weeks of exercise is necessary to lower the individual's resting heart rate below 70 beats per minute.

This cubic inequality can be solved by hit and trial method.

when x = 7.

\(-0.1x^{3} + 0.6x^{2} +85 < 70\\\)

\(=-0.1*7^{3} + 0.6*7^{2} +85\) = 80.1

80.1 > 70

Thus, x = 7 is not suitable.

when x = 8.

\(-0.1x^{3} + 0.6x^{2} +85 < 70\\\)

\(=-0.1*8^{3} + 0.6*8^{2} +85\) = 72.2

72.2 > 70

Thus, x = 8 is not suitable.

when x = 9.

\(-0.1x^{3} + 0.6x^{2} +85 < 70\\\)

\(=-0.1*9^{3} + 0.6*9^{2} +85\) = 60.7

60.7 < 70

Thus, x = 9 is suitable.

Answer:

x = 12

Step-by-step explanation:

In a pair of intersecting lines the vertically opposite angles are equal.

\( \longrightarrow \) (6x + 7)° = (8x - 17)°

\( \longrightarrow \) 6x + 7 = 8x - 17

Subtract 8x + 7 from both sides:

\( \longrightarrow \) 6x + 7 - (8x + 7) = 8x - 17 - (8x + 7)

\( \longrightarrow \) (6x - 8x) + (7 - 7) = (8x - 8x) + (-17 - 7)

6x - 8x = -2x:

\( \longrightarrow \) -2x + (7 - 7) = (8x - 8x) + (-17 - 7)

7 - 7 = 0:

\( \longrightarrow \) -2x = (8x - 8x) + (-17 - 7)

8x - 8x = 0:

\( \longrightarrow \) -2x = -17 - 7

-17 - 7 = -24:

\( \longrightarrow \) -2x = -24

Divide both sides by -2:

\( \longrightarrow \) \( \sf \dfrac{-2x}{-2} = \dfrac{-24}{-2} \)

\( \sf \dfrac{-2}{-2} = 1 \)

\( \longrightarrow \) \( \sf x = \dfrac{-24}{-2} \)

\( \sf \dfrac{-24}{-2} = 12 \)

\( \longrightarrow \) x = 12
