How is Class 9 slope calculated?.
The slope is calculated by the formula : [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The slope is defined as the ratio of the change in the y-axis to the change in the x-axis.
The slope of a straight line will define the line’s angle of steepness from the horizontal whether it rises or falls. When the line neither rises nor falls, then its slope will be zero.
This is the case with a horizontal line where it extends infinitely to its left or right but without any sign of rise or fall.
In a coordinate system, points are represented by a pair of coordinate values. This pair is having y to values x-value and y-value.
For example (x,y) will represent a point on the geometrical plane. Also, (0,0) will represent the origin point.
Let (x₁,y₁)and(x₂,y₂) x₁, x₂ are the coordinates of x-axis and y₁,y₂ are the coordinates of y-axis
The formula to calculate slope is defined as given below,
m= y2−y1x2−x1

What is linear equation?A linear equation is one in which the variable's maximum power is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation. A linear equation with two variables has the formula Ax + By = C as its standard form. Here, the variables are x and y, the coefficients are A and B, and the constant is C.A linear equation is one that has the highest degree of 1 possible. This indicates that there are no variables in a linear equation with exponents greater than 1.Putting the value O (1,0) in both equations we get that this point satisfies both equations.

The second term of a G.P is 6, and the fifth term is 48, find the common ratio and the 3rd term of the G.P.
Answer:
Common ratio = 2, Third term = 12
Step-by-step explanation:
ar⁴ = 48........ equation 1
ar = 6.......... equation 2
divide equation 1 by equation 2
r³ = 8
r = ³√8
r = 2
To get the third term we must first get the first term
Since ar = 6 and r = 2, then 2a = 6 and a = 3
3rd term = ar²
3 × 2² = 3 × 4 = 12
Answer:
r = 2 and a₃ = 12
Step-by-step explanation:
the nth term of a GP is
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
given a₂ = 6 and a₅ = 48 , then
a₁r = 6 → (1)
a₁[tex]r^{4}[/tex] = 48 → (2)
divide both sides of (2) by (1) to eliminate a₁
[tex]\frac{a_{1}r^{4} }{a_{1}r }[/tex] = [tex]\frac{48}{6}[/tex] ( cancel r and [tex]r^{4}[/tex] by r )
r³ = 8 ( take cube root of both sides )
r = [tex]\sqrt[3]{8}[/tex] = 2
substitute r = 2 into (1) and solve for a₁
a₁ × 2 = 6 ( divide both sides by 2 )
a₁ = 3
a₂ = a₁ × r = 3 × 2 = 6
a₃ = a₂ × 3 = 12

How do you know if a function is convex or non convex?.
One of the most important considerations when designing or evaluating a function is its convexity. A function is said to be convex if it is possible to represent its shape in a single, continuous surface.
However, it is not always straightforward to determine if a particular function is convex or not. There are various criteria that can be used to determine whether a given function is convex or nonconvex. These include the "vertex test" and the "region test." The vertex test is a simple and intuitive way to determine whether or not a function is convex. It can be performed as follows: First, identify any critical points of the function using the first derivative. Then, draw a graph of these functions and identify the point at which the graphs of these functions intersect. The point where this intersection occurs is the vertex of the function. If the graph of the function does not intersect at any point, then it cannot be concave and can therefore be considered to be convex.

How do you graph the inverse of a square root?.
Step 1: Perform the horizontal line test as the first step. Move a horizontal line from the graph's bottom to its top to accomplish this. The graph fails the horizontal line test and does not have an inverse if the horizontal line touches two or more points on the graph at any given time. Continue to Step 2 if the graph passes the horizontal line test.
Step 2: Determine the given function's domain and range in step two.
Step 3: A square root function is the inverse of a quadratic function. We switch the domain and range in order to graph the inverse. The graph has the same structure but has been rotated to have the original function's domain and range switched.
A quadratic function is the inverse of a square root function. We switch the domain and range of the original function to get the graph of the inverse. In other words, the range of the inverse quadratic function is the domain of the square root function. The domain of the inverse quadratic function is the range of the square root function.

The temperature changed at a constant rate between noon and 3:30 p.m. At what rate, in degrees F per hour, did the temperature change between noon and 3:30 p.m.? Show your work or explain your answer.
Answer:
To solve this problem, we need to calculate the change in temperature between noon and 3:30 p.m. and then divide that by the number of hours between noon and 3:30 p.m.
Let's say the temperature at noon was 70 degrees F and the temperature at 3:30 p.m. was 75 degrees F.
The change in temperature between noon and 3:30 p.m. is 75 - 70 = 5 degrees F.
The number of hours between noon and 3:30 p.m. is 3.5 hours.
Therefore, the rate of change in temperature between noon and 3:30 p.m. is 5 degrees F / 3.5 hours = 1.43 degrees F per hour.

In information, the standard deviation is a degree of the quantity of variation or dispersion of a fixed of values. A low standard deviation indicates that the values tend to be near the implied (additionally called the predicted price) of the set, whilst an excessive preferred deviation suggests that the values are spread out over a wider variety.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles.
An angle that is greater than 180 degrees and less than 360 degrees is referred to as a reflex angle. Reflex angles include, for instance, 270 degrees. There are several sorts of angles in geometry, including acute, obtuse, and right angles—angles that are less than 180 degrees.
A reflex angle equals the summation of 180 degrees and any of the primary angles (acute, right and obtuse angles). Therefore,
