The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run.
How do you find slope of a line?A line has the property that its slope remains constant throughout. Therefore, you may determine the slope by selecting any two points along the line's graph.
The definition of slope in mathematics is pretty close to how we normally define it. Slope is a mathematical term used to indicate a line's steepness and direction. A line's slope can be inferred from its graph alone, especially in relation to other lines plotted on the same coordinate plane.
slope=rise/run.
The ratio of the change in the y-value to the change in the x-value can also be used to determine slope. For instance: Given two points on the line, P = (0, -1) and Q = (4,1), we may compute

The slope of the given linear relationship is 5 (A).
From the question, we have 5 different points that create a linear relationship. To determine the slope of the linear relationship, we can choose 2 random sequence points.
We might choose:
Point 1 = (0,-2)
Point 2 = (1,3)
We can find the slope of the relationship using formula of:
m = y2 - y1
x2 - x1
m = 3- (-2)
1 - 0
m = 5
1
m = 5
To ensure our finding, we can choose another pair of random points, for example:
P1 = (-2, -12)
P2 = (-1, -7)
We can use the slope formula:
m = y2 - y1
x2 - x1
m = -7 - (-12)
-1 - (-2)
m = 5
1
m = 5
Hence, the slop of the linear relationship between all the given points are 5.

use the definition of continuity and the properties of limits to show that the function is continuous at the number a
Answers
Continuity is the formulation of a function that varies with no breaks or jumps. The concepts of limits and continuity have been used to show that the function is continuous at the number a below.
If a graph has no holes asymptotes or breaks at any point then the function is said to be continuous. Or if we can draw the function without lifting our pen then it is called continuous.
The conditions which it should satisfy are,
1)The limit must exist at that point.
2) The function must be defined at that point, and
3)The limit and the function must have equal values at that point. So,
A function f(x) is said to be continuous at x=a if,
lim f(x) = f(a)
x→a
A function is said to be continuous on the interval [a,b] if it is continuous at each point in the interval.

Answers
A starting value or starting point is what is meant by the term "initial value" (plural "initial value").
What is meant by initial value?The definition of an initial value is accurate: It is a starting value or starting point. When the input value is 0, the initial value of a function is its output. For instance, the starting value would be the amount of money you had on day 0 if your function was to track how much money you made over a specific period of time. A function's initial value is the value it has when x is zero. This corresponds to the y-intercept. The graph reveals that our line crosses the y-axis at the coordinates 0 and 8. When x=0 is entered into an exponential function, the result is the function's initial value. The initial value of the exponential function f(x) = abx f (x) = a b x is a.Given,

Answers
The triangular base in the xy plane can be described by the equation y = mx + b, where m is the slope of the line and b is the y-intercept.
In the xz plane, the solid has a plane defined by the equation z = f(x). This equation can be derived from the equation of the base by substituting the y values with the corresponding mx + b values. Similarly, in the yz plane, the solid has a plane defined by the equation z = g(y). This equation can be derived from the equation of the base by substituting the x values with the corresponding (y - b)/m values. To calculate the area of the solid, we can use the formula A = 1/2h(b1 + b2), where h is the height of the solid and b1 and b2 are the lengths of the two bases. The area of the solid can then be found by substituting the appropriate values into this formula.

which of the following shows a correct side-by-side bar chart with store location on the horizontal axis and side-by-side bars of the percentage of time spent on each task?
Answers
The resulting bar chart would show that in Store A, the employees spend 30% of their time on stocking, 40% on cashiering, and 30% on cleaning.
To create a side-by-side bar chart for this data, we would first organize the data into a table with store locations as the rows and tasks as the columns. Each cell in the table would contain the percentage of time spent on that task at that store location.
For example, the table might look like this:
Stocking Cashiering Cleaning
Store A 30% 40% 30%
Store B 25% 35% 40%
Store C 35% 25% 40%
To create the bar chart, we would then place the store locations on the x-axis and use different colors to represent the different tasks. The length of each bar would correspond to the percentage of time spent on that task at that store location.
The resulting bar chart would show that in Store A, the employees spend 30% of their time on stocking, 40% on cashiering, and 30% on cleaning.

If the similar figure is smaller than the original then the scale factor is a fraction. If the similar figure is larger than the original then the scale factor is a whole number.
How do scale factors work ?The scale factor is a ratio that compares the corresponding side lengths of two similar figures. If the similar figure is smaller than the original, the scale factor is a fraction less than 1, for example, 2/3 or 3/4. This means that the corresponding side lengths of the similar figure are 2/3 or 3/4 of the corresponding side lengths of the original figure.

The method of determining the mean of a set of data that are grouped together in several categories is known as the mean of grouped data.
A frequency table must be set across the data's frequencies in order to calculate the mean of grouped data, which makes the calculation simple.
[ Here we need to create a frequency table to solve the problem ]
Here we have
Score 10 20 30 40
No of students 6 7 8 ?
To calculate the average of the score make the table as follows
Let 'x' be the number of students that the class average over 23
Score (x) No of students(f) fx
10 6 60
20 7 140
30 8 240
40 x 40x
∑f = 21 + x ∑fx = 440 + 40x
Average of score = ∑fx/ ∑f = [ 440 + 40x ]/21+x
As we assumed the average score is 23
=> [440 + 40x ]/21+x = 23
=> [440 + 40x ] = [ 21+x ] (23)
=> 440 + 40x = 483 + 23x
=> 40x - 23x = 483 - 440
=> 17x = 43

Answers
Answer:
5
Step-by-step explanation:
To find the derivative of a function at a given point, we need to use the concept of limits and the definition of a derivative. In this case, we are trying to find dy/dx at the point (-1,2) for the given function y^2-2xy+3x^3=5
Since the function is equal to 5, we can assume that y^2-2xy+3x^3-5 =0, then we can find the partial derivative with respect to x and y.
∂/∂x (y^2-2xy+3x^3-5) = -2y + 9x^2
∂/∂y (y^2-2xy+3x^3-5) = 2y - 2x
Now we can substitute the point (-1,2) into the equation,
dy/dx = -2(2) + 9(-1)^2 = -4 + 9 = 5
Therefore, dy/dx at the point (-1,2) is equal to 5
It's important to note that this result is valid only for this specific point, it does not mean that it's the slope of the function in general.

Answers
The number of squares that can be formed on a grid with n points on one side is (n² - (n-1)²).
The number of squares that can be formed with all their vertices belonging to the points of a grid can be calculated using the formula:
n² - (n-1)²
where n is the number of points on one side of the grid.
This is because there are n² total points on the grid, and each point can be used as a vertex for n-1 squares (when n>1) in the horizontal and vertical directions. However, each of these squares is counted twice, once for each corner point. So we subtract (n-1)² to account for the overcounting.
For example, if there are 4 points on one side of the grid, the number of squares that can be formed is 4² - (4-1)² = 16 - 9 = 7 squares.

Answers
v1 and v2 be two nonzero vectors perpendicular to 2 in R3.
We can calculate the dot product of each vector with 2 to determine if they are perpendicular.
v1•2 = (x1, y1, z1)•(2, 0, 0) = 2x1
v2•2 = (x2, y2, z2)•(2, 0, 0) = 2x2
If 2x1 = 0 and 2x2 = 0, then v1 and v2 are perpendicular to 2. To make sure they are not scalar multiples of each other, we can check that the coordinates of each vector are not all the same. Let's say v1 = (a, b, c) and v2 = (d, e, f). If a≠d, b≠e, and c≠f, then v1 and v2 are not scalar multiples of each other.
For example, let v1 = (1, 2, 3) and v2 = (4, 5, 6). Then v1•2 = 2 and v2•2 = 8, which both equal 0. Therefore, v1 and v2 are perpendicular to 2. Furthermore, since 1≠4, 2≠5, and 3≠6, v1 and v2 are not scalar multiples of each other.
