Answer:
It has a slope of zero because the change in the y-values is 0.
Step-by-step explanation:
The line passes through points (9, 30) and (18, 30) and has a slope of zero because the change in the y-values is 0.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, A line passes through the points (9, 30) and (18, 30).
We know slope(m) = (y₂ - y₁)/(x₂ - x₁).
∴ Slope(m) = (30 - 30)/(18 - 9).
Slope(m) = 0/9.
Slope(m) = 0.
The line has a slope of zero because the change in the y-values is 0.
So it must be a line parallel to the x-axis.

What
is the difference between Variance and Standard Deviation?
Give
examples of how they are applied.
Variance and standard deviation are both measures of the dispersion or spread of a dataset, but they differ in terms of the unit of measurement.
Variance is the average of the squared differences between each data point and the mean of the dataset. It measures how far each data point is from the mean, squared, and then averages these squared differences. Variance is expressed in squared units, making it difficult to interpret in the original unit of measurement. For example, if we are measuring the heights of individuals in centimeters, the variance would be expressed in square centimeters.
Standard deviation, on the other hand, is the square root of the variance. It is a more commonly used measure because it is expressed in the same unit as the original data. Standard deviation represents the average distance of each data point from the mean. It provides a more intuitive understanding of the spread of the dataset. For example, if the standard deviation of a dataset of heights is 5 cm, it means that most heights in the dataset are within 5 cm of the mean height.
To illustrate the application of these measures, consider a dataset of test scores for two students: Student A and Student B.
If Student A has test scores of 80, 85, 90, and 95, and Student B has test scores of 70, 80, 90, and 100, we can calculate the variance and standard deviation for each student's scores.
The variance for Student A's scores might be 62.5, and the standard deviation would be approximately 7.91. For Student B, the variance might be 125 and the standard deviation would be approximately 11.18.
These measures help us understand how much the scores deviate from the mean, and how spread out the scores are within each dataset.

what is isometric perspective? multiple choice question. a system of converging lines that are looked down on from an aerial perspective parallel lines that all converge at a single point diagonal lines that are parallel without converging a system of diagonal lines that converge at a series of points
Isometric perspective refers to a system of diagonal lines that are parallel without converging. This perspective is commonly used in technical drawings and architectural illustrations to represent three-dimensional objects in a visually balanced and proportional manner.
Isometric perspective is a method of representing three-dimensional objects on a two-dimensional surface. It involves creating an illusion of depth and dimension by using a specific set of rules for drawing lines and angles. Isometric perspective is characterized by the use of parallel lines that remain parallel and do not converge, creating a sense of uniformity and stability in the representation.
In isometric perspective, the lines are typically drawn at a 30-degree angle from the horizontal plane. This angle creates a sense of depth and allows for accurate scaling of the object's dimensions. The vertical lines remain vertical, while the horizontal lines are drawn at a 30-degree angle to the horizontal plane.
Unlike other perspective techniques, such as linear perspective, isometric perspective does not include vanishing points or converging lines. Instead, it relies on the principle that all lines that are parallel in reality remain parallel in the isometric representation.
By following the rules of isometric perspective, an artist or designer can accurately depict the three-dimensional qualities of an object in a two-dimensional format. This technique is widely used in technical drawings, architectural illustrations, and engineering diagrams, as it provides a clear and consistent representation of objects from various angles.

2|x - 3| - 5 = 7
“solve the equation”
Answer:
Combine solutions: x=-3 or x=9
Step-by-step explanation:
Answer:
x = - 3, x = 9
Step-by-step explanation:
Given
2| x - 3 | - 5 = 7 ( add 5 to both sides )
2|x - 3 | = 12 ( divide both sides by 2 )
| x - 3 | = 6
The absolute value function always gives a positive value, however, the expression inside the bars can be positive or negative, that is
x - 3 = 6 or - (x - 3) = 6
Solving both equations
x - 3 = 6 ( add 3 to both sides )
x = 9
or
- (x - 3) = 6
- x + 3 = 6 ( subtract 3 from both sides )
- x = 3 ( multiply both sides by - 1 )
x = - 3
As a check
2|9 - 3| - 5 = 2|6| - 5 = 12 - 5 = 7 ← Correct
or
2|- 3 - 3| - 5 = 2|- 6| - 5 = 2 |6| - 5 = 12 - 5 = 7 ← Correct
Thus the solutions are x = - 3, x = 9

5. If f(0,0) = 0 and xy f(x, y) if (x, y) = (0,0), x² + y² prove that (D₁f) (x, y) and (D₂f) (x, y) exist at every point of R², although fis not continuous at (0,0). =
The partial derivatives (D₁f) (x, y) and (D₂f) (x, y) exist at every point of R², despite f not being continuous at (0,0).
The existence of partial derivatives (D₁f) (x, y) and (D₂f) (x, y) at a point (x, y) in R² is determined by the existence of the corresponding directional derivatives. The directional derivative in the direction of the x-axis, (D₁f) (x, y), measures the rate of change of f with respect to x, while the directional derivative in the direction of the y-axis, (D₂f) (x, y), measures the rate of change of f with respect to y.
In this case, f(0,0) is defined as 0, and the expression xy f(x, y) is given as x² + y². Since the given function evaluates to 0 at (0,0), we can conclude that the function is differentiable along the x and y axes, and therefore, the partial derivatives (D₁f) (x, y) and (D₂f) (x, y) exist at every point of R².
However, it is important to note that the existence of partial derivatives does not imply the continuity of the function. In this case, although the partial derivatives exist, the function f is not continuous at (0,0) because the limit of f as (x, y) approaches (0,0) does not exist. Thus, the existence of partial derivatives alone does not guarantee the continuity of the function.

If a function f is continuous for all x and if f has a relative maximum at (-1, 4) and a relative minimum at (3, -2), which of the following statements must be true? (a) The graph of f has a point of inflection somewhere between x = -1 and x= 3 (b) f'(-1) = 0 (c) this is wrong (d) The graph of f has a horizontal tangent line at x = 3 (e) The graph of f intersects both axes
If a function f is continuous for all x and if f has a relative maximum at (-1, 4) and a relative minimum at (3, -2), then the following statements must be true: Option (b) f'(-1) = 0 and Option (d) the graph of f has a horizontal tangent line at x = 3
Explanation: The relative maximum of a function is the highest point in a particular set, and the relative minimum is the lowest point. If a function f is continuous for all x and has a relative maximum at (-1, 4) and a relative minimum at (3, -2), then the following statements must be true. The value of the derivative will be equal to zero at relative maximum and relative minimum points of the function. In other words, f'(-1) = 0 and f'(3) = 0. Thus, the option (b) is correct. The graph of f has a horizontal tangent line at the relative minimum and maximum points of the function. This implies that the graph of f has a horizontal tangent line at x = -1 and x = 3. Therefore, the option (d) is correct. The graph of f may or may not intersect both axes. There is no proof that the function f will intersect both axes. Therefore, option (e) is incorrect. The point of inflection is a point on a curve where the concavity of the function changes. Since the function f has a relative maximum at (-1, 4) and a relative minimum at (3, -2), there is no certainty that the graph of f has a point of inflection between x = -1 and x = 3. As a result, option (a) is incorrect. Thus, the correct options are (b) f'(-1) = 0 and (d) The graph of f has a horizontal tangent line at x = 3.

a: b = 1:6
a:c = 3:1
How many times bigger is b than c?
Answer:
18
Step-by-step explanation:
Expressing the ratios in fractional form
[tex]\frac{a}{b}[/tex] = [tex]\frac{1}{6}[/tex] ( cross- multiply )
b = 6a → (1)
and
[tex]\frac{a}{c}[/tex] = [tex]\frac{3}{1}[/tex] ( cross- multiply )
a = 3c ← substitute into (1) , thus
b = 6 × 3c = 18c
Then b is 18 times bigger than c
B is 18 times bigger than C.
Given that,
a: b = 1:6 a:c = 3:1.Based on the above information, the calculation is as follows:
[tex]\frac{a}{b} = \frac{1}{6}[/tex]
And,
[tex]\frac{a}{c} = \frac{3}{1}[/tex]
Now we have to cross multiplied
So it comes 18
Therefore we can conclude that B is 18 times bigger than C.
