How are log and exponential functions inverse?.
Logarithm and exponential functions are inverse as log(ex)=x and elogx=x.
Knowing that logarithms were once a tool for multiplication when ships employed celestial navigation may be helpful to the layperson. The product of two numbers' logarithms is equal to the total of their individual logarithms. Numerous log tables were published and utilized mechanically.
In 1958, this was an excellent supplemental math topic. The slide rule converts multiplication to addition of lengths using one axis graphs of an exponential function and a graphic log table as a physical correlate. As a result, the logarithm of a product is equal to the sum of the logarithms of its components.

What is the equation for the line in slope-intercept form?
Answer: The answer would be y = −4x − 5
Step-by-step explanation: I hope this helps!
Sooo yeah umm..... I need help.
Answer:
[tex]\mathrm{Slope } = \dfrac{2}{3}[/tex]
Step-by-step explanation:
To find the slope take any two convenient x, y value combo.
Find the difference between the two y-values(we call it rise).
Find the difference in the corresponding x-values (we call this the run)
[tex]\dfrac{rise}{run} = slope[/tex]
Take points (3, 1) and (6,3). I could choose any two points but working with positive numbers makes it easier
Rise = 3- 1 = 2
Run = 6 - 3 = 3
[tex]\mathrm{Slope } = \dfrac{2}{3}[/tex]
Just for the heck of it let's take two other points to make sure we haven't goofed
Take points (-1, - 5/3) and (1, -1/3)
rise = -1/3 - (-5/3) = -1/3 + 5/3 = 4/3
run = 1 - (-1) = 2
rise over run = 4/3 ÷ 2 = 4/3 x 1/2 = 2/3

How do you sketch the graph of a function of two variables?.
A two-variable function's graph can be thought of as a surface in three dimensions.
The points (x, y, f(x, y)) where x and y are in the domain make up the graph of z=f(x, y). You can fine-tune the shape of the surface by drawing the curve k=f(x, y) in the plane z=k for different values of k. For instance, we're trying to comprehend the graph of z=f(x, y)=x2+y2. Keep in mind that k=f(x, y) is a circle for k>0 and since 0=x2+y2 implies that x=y=0.
Additionally, it is symmetric in relation to the z axis. We have a parabola for x=k or y=k. As a result, the graph represents the revolution of the parabola z=x2 over the z axis (see Thomas, math).

How do you find the mean value of a Class 10?.
The mean is dividing the sum of all values in a data set by the number of values.
Average is another word for "mean." For instance, if we say that the average height of the 9th grade class is 150 cm, it signifies that this is the mean of all of the kids' heights. The statistical notion of mean, which is employed in a variety of financial areas and corporate appraisal, has significant financial implications. The three statistical measurements of a data set's central tendency are mean, median, and mode.
The mean, which measures the central tendency of the data, is the average or computed central value of a set of numbers. The statistical metric known as central tendency identifies the complete collection of data or distribution by a single value. It offers a precise description of the entire set of facts. The ratio of the sum of all observations to the total number of observations is another way to define the mean in statistics.

Is Y =- 3 a horizontal line?.
So, Y = -3 is not a horizontal line but a vertical line.
A horizontal line is a line that runs along the x-axis and has a constant y-value. In the equation of a line, y = mx + b, a horizontal line has a slope of zero (m = 0) and a y-intercept of the constant value (b = constant).
The equation Y = -3 is not a horizontal line. This is an equation of a vertical line, which is a line that runs along the y-axis and has a constant x-value. In this case, the constant x value is -3.
A vertical line has no slope since it does not change in the x direction. The x-value is constant, which means the slope is undefined.
In a graph, a horizontal line can be represented by a straight line that is parallel to the x-axis, while a vertical line is represented by a straight line that is parallel to the y-axis.
To summarize, Y = -3 is not a horizontal line but a vertical line, which means that all the points on this line have the same x-coordinate (-3) and can take any value for y.

In the coordinate plane, if a line is drawn to connect two points (4, 2), and (8, 6), then the coordinates of the midpoint of the line joining these two points are ({4 + 8}/2, {2 + 6}/2) = (12/2, 8/2) = (6, 4).
What is midpoint?Midpoint refers to a point that is in the middle of the line joining two points. The two reference points are the endpoints of a line, and the midpoint is lying in between the two points. The midpoint divides the line joining these two points into two equal halves. Further, if a line is drawn to bisect the line joining these two points, the line passes through the midpoint.
The midpoint formula is used to find the midpoint between two points whose coordinates are known to us. The midpoint formula is also used to find the coordinates of the endpoint if we know the coordinates of the other endpoint and the midpoint. In the coordinate plane, if a line is drawn to connect two points (4, 2), and (8, 6), then the coordinates of the midpoint of the line joining these two points are ({4 + 8}/2, {2 + 6}/2) = (12/2, 8/2) = (6, 4).

The value of x is 39 and the values of angle m1 and m2 is 63 and 117. We can solve the question using linear pair.
What is linear pair?
When two lines meet at a single point, a pair of linear angles is created. If the angles follow the point where the two lines cross, they are considered to be linear pair. A linear pair's angles add up to 180° in every case. These angles are additionally referred to as. Angles with a shared vertex are those that are adjacent.
Therefore, the linear angles also have a common vertex in this instance.
Additionally, a common arm that symbolizes both angles will be present.
A ladder against a wall that creates linear angles at the ground is an example of a linear pair in real life. One who is straight is represented by linearity.
Using linear pair, we have equation
m1 +m2 = 180

What is right triangle?A right triangle, right-angled triangle, or more formally an orthogonal triangle—previously known as a rectangled triangle—is a triangle with one angle that is a right angle (i.e., a 90-degree angle), meaning that two of its sides are perpendicular. The foundation of trigonometry is the relationship between the sides and other angles of a right triangle.
The hypotenuse is the side that faces the right angle (side c in the figure). Legs are the sides that are next to the right angle (or catheti, singular: cathetus). Side a can be thought of as the side that is adjacent to angle B and opposite to (or opposite) angle A, whereas side b is the side that is adjacent to angle A and opposite to angle B.
Given a right triangle with base = 8 and an angle = 24°
Using angle sum property of triangle
24 + 90 + angle L = 180
L = 66°
Using Sohcahtoa
Tangent: tan(θ) = Opposite / Adjacent
tan(24°) = LK/8
0.445 = LK/8
LH = 8 × 0.445
LK = 3.56
LM = [tex]\sqrt{MK^2 + LK^2}[/tex]

Therefore, the burglar's initial theft was $12,000.
To begin, we may express the data in the problem using algebra.
Let x represent the original sum that the burglary victim took.
The thief was left with x/2 + 2000 after giving the first guard the other half of the money plus $2,000, according to the issue.
He had (x/2 + 2000)/2 + 2000 when he gave the same sum to the second guard.
He also handed the third guard the same amount, leaving him with
((x/2 + 2000)/2 + 2000)/2 + 2000.
However, because we are certain that he left with $9,000 more than when he came, we may state:
((x/2 + 2000)/2 + 2000)/2 + 2000 = x + 9000
