Graph y=-7 by plotting y-intercept (0,-7) and all points have y=-7, it is a horizontal line.

What is graph ?

A graph is a mathematical structure used to represent relationships between objects. In a graph, objects are represented by vertices (or nodes) and relationships are represented by edges (or arcs). Graphs can be used to model a wide variety of real-world systems, including networks of roads, social networks, and the internet.

To graph y = -7, you can start by plotting the y-intercept, which is the point at which the line crosses the y-axis. In this case, the y-intercept is (0, -7) because when x = 0, y = -7.

To graph the line, you can then pick any other x-value, substitute it into the equation, and find the corresponding y-value. For example, if you pick x = 1, then y = -7. So, you can plot the point (1,-7) on the graph.

You can repeat this process with different x-values and plot more points on the graph.

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

The angle of the line is given as follows:

θ = -11.89º.

The two points on the line are given as follows:

A(-8,6) and B(11,2).

Given two points, the slope is obtained by the division of the change in y by the change in x, hence:

m = (2 - 6)/(11 + 8)

m = -0.2105.

The slope represents the tangent of the angle, hence the angle is the arc tangent of the slope, thus:

θ = arctan(-0.2105)

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).

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).

By using the fact that the triangles are similar, we can write and solve an equation to find that t = 11.

Here we know that K is the midpoint of GJ and I is the midpoint of HJ, this means that triangle JKI is similar to JHG, but dilated by a factor 1/2.

That means that we can write:

(1/2)HG = IK

We know that:

GH = t + 47

IK = -5t + 84

Replacing these in the equation above, we will get:

(1/2)*(t + 47) = -5t + 84

t + 47 = 2*(-5t + 84)

t + 47 = -10*t + 168

t + 10t = 168 - 47

the equation that can be used to determine the value of the artwork in "x" year is A = 1500(1 + 0.0128)^x.

An equation that can be used to determine the value of the artwork in "x" years is a compound interest equation. This type of equation is used to calculate the value of an investment over time, taking into account the initial investment amount and the interest rate.

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. It can be contrasted with simple interest, which is calculated only on the principal amount.

Compound interest is considered to be more beneficial for savers and investors, as it allows for interest to be earned on previously earned interest, leading to faster growth of the principal.

In this case, the artwork appreciates by 1.28% in value every year and was purchased for $1500. The formula for compound interest is:

A = P(1 + r)^n

Where:

A = the future value of the artwork

P = the initial investment (the purchase price of $1500)

r = the interest rate (1.28% per year)

n = the number of years

To use this equation, we need to convert the interest rate from a percentage to a decimal. We do this by dividing the interest rate by 100. So, 1.28% as a decimal is 0.0128.

Now we can substitute the values into the equation:

A = 1500(1 + 0.0128)^x

Therefore, the equation that can be used to determine the value of the artwork in "x" year is A = 1500(1 + 0.0128)^x.

The figure represents the angle of refraction

The angle of refraction is represented by the angle θ2 

Light rays that are refracted change their direction as they travel through different media. Light changes direction when it travels from one medium to another.

The refracted beam will bend toward the normal if the incident light is moving from a less dense to a denser material. Here, the angle of refraction (hence, "r") is always smaller than the angle of incidence. (In line with the diagram)

Similar to this, the refracted ray will bend away from the normal if the incident light is moving from a denser medium to a less dense material. In this situation, the angle of incidence is never greater than the angle of refraction, or "r."

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.

For the given right triangle, L = 66°, LK = 3.56, and the hypotenuse, LM = 8.75.

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.
