Answer:
Step-by-step explanation:
In the context of communication, a medium is a substance or material through which information or messages are conveyed from a sender to a receiver. Examples of media include photographs, newspaper articles, paintings, videos, radio broadcasts, and so on. These media carry information from the person or organization that created them to the people who consume them, whether it be to inform, entertain, or educate.
A cookbook, on the other hand, may not be considered a medium in the same way as the other options, as it is not primarily used to convey information or messages from a sender to a receiver. While a cookbook contains information, such as recipes and instructions for preparing food, this information is not usually communicated from one person to another in the same way as, for example, a photograph or a newspaper article. A cookbook is more like a reference book or guidebook, which people use to obtain information rather than as a means of transmitting information.
All of the options given could be considered examples of media. However, if we interpret "medium" as a substance or material through which something is transmitted or conveyed, then "cookbook" might not be considered a medium. A cookbook is a book that provides instructions on how to prepare food and does not necessarily serve as a substance through which information is transmitted or conveyed. So the answer would be C. Cookbook.
Answer:
C. Cookbook
Step-by-step explanation:
The other answer choices represent examples of communication medium. A communication medium is a system or channel through which information disseminated to others.
A cookbook is a set of instructions for a specific task and therefore does not fall under the generalized category of medium.

The graph shows the location of all solutions for some linear equation. The coordinates of two of the points are labeled. Which linear equation matches this graph? A) x + y = 6 B) y = 2x + 4 C) 3x + y = 9 D) y = −2(x − 5) − 6
The linear equation for coordinate points (-2,8) and (5,-6) is option B: y = -2x + 4.
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
Since there are two points on the graph, use the slope-intercept form of a linear equation to find the equation that matches the graph.
The slope-intercept form is -
y = mx + b
Where m is the slope and b is the y-intercept.
To find the slope, we use the two given points -
m = (y2 - y1) / (x2 - x1)
m = (-6 - 8) / (5 - (-2))
m = -14 / 7 = -2
To find the y-intercept, we can use one of the points and the slope -
y = mx + b
8 = (-2) × (-2) + b
8 = 4 + b
b = 4
So the equation that matches the graph is -
y = -2x + 4
Therefore, the equation is -2x + 4.

Find the solution to the system of equations represented by the matrix shown below.
The solution of the system of equations is:
x = 12, y = 11, z = 2
How to solve the system of equations?We can rewrite our system of equations as:
x + y + z = 25
5x + y + 9z = 89
-7x + 6y + 6z = -6
First, if we subtract the first equation and the second one, we will get:
(5x + y + 9z) - (x + y + z) = 89 - 25
4x + 8z = 64
And if we subtract 6 times the first equation from the third one, we will get:
-7x + 6y + 6z - 6*(x + y + z) = -6 - 6*25
-13x = -156
We can solve this for x:
x = -156/-13 = 12
Now we know the value of x, replacing it in:
4x + 8z = 64
Will give:
4*12 + 8z = 64
8z = 64 - 4*12 = 16
z = 16/8 = 2
And the value of y will be given by:
x + y + z = 25
12 + y + 2 = 25
14 + y = 25
y = 25 - 14 = 11
Then the solution is:
x = 12, y = 11, z = 2

Suppose you deposit $1,000 in a savings account that pays interest at an annual rate of 4%. If no money is added or withdrawn from the account how many years will it take for the account to contain $1500
The number of years for the interest amount to reach $ 1,500 at 4 % is given by b = 10.35 years
What is Compound Interest?Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.
The formula for calculating Compound Interest is
A = P ( 1 + r/n )ⁿᵇ
where A = Final Amount
P = Principal
r = rate of interest
n = number of times interest is applied
b = number of time periods elapsed
Given data ,
Let the amount invested be P = $ 1,000
Let the number of years be = b
Let the number of times the interest is applied n = 1
Let the rate of interest be r = 4 %
Now , the compound interest + amount = $ 1,500
A = P ( 1 + r/n )ⁿᵇ
And , the number of years b = ln ( A / P ) / n [ ln ( 1 + r / n ) ]
On simplifying , we get
b = ln ( 1,500.00 / 1,000.00 ) / ( 1 × [ ln ( 1 + 0.04 ) ] )
b = 10.338 years
Hence , the number of years is 10.35 years

How to determine the image of the polygonFrom the question, we have the following coordinates that can be used in our computation:
(1, 0), (2, 0), (0, 2) and (2, 2)
The location of point G is
G = (3, -1)
To rotate about point G, we start by subtracting the points from G
So, we have
[(1, 0), (2, 0), (0, 2) and (2, 2)] - (3, -1)
This gives
(-2, 1), (-1, 1), (-3, 3) and (-1, 3)
The rule is 90 degrees clockwise rotation
This is represented as
(x, y) ⇒ (y, -x)
So, we have
(-2, 1), (-1, 1), (-3, 3) and (-1, 3) ⇒ (1, 2), (1, 1), (3, 3) and (3, 1)

Step-by-step explanation:
The weekly salaries of teachers in one state are normally distributed with a mean of $490 and a standard deviation of $45. What is the probability that a randomly selected teacher earns more than $525 a week?
your answer should be a decimal rounded to the fourth decimal place
The probability that a randomly selected teacher earns more than $525 a week is 0.1820. Therefore, the probability that a randomly selected teacher earns more than $525 a week is 0.2177.
This is calculated by using the standard normal distribution formula:
P(x > 525) = 1 - P(x ≤ 525) = 1 - 0.8413 = 0.1820
The probability that a randomly selected teacher earns more than $525 a week can be found by calculating the z-score for $525 and then using the standard normal table to find the probability.
The z-score is calculated as follows:
z = (x - μ)/σ
Where x is the value we are interested in, μ is the mean, and σ is the standard deviation.
Plugging in the values from the question, we get:
z = (525 - 490)/45 = 0.78
Now, we can use the standard normal table to find the probability that a randomly selected teacher earns more than $525 a week. The table gives us the probability that a value is less than a given z-score, so we need to subtract the probability from 1 to find the probability that a value is greater than the z-score.
The probability that a value is less than 0.78 is 0.7823. So, the probability that a value is greater than 0.78 is 1 - 0.7823 = 0.2177.
Therefore, the probability that a randomly selected teacher earns more than $525 a week is 0.2177.

Show that the path given by r(t)=(e" sint,e- cos t, e) intersects the sphere 2y224 once, traveling from outside the sphere to inside as t goes from -oo to oo. I
Answer:
Step-by-step explanation:
We need to show that the path given by r(t) = (e^t sin t, e^(-t) cos t, e) intersects the sphere 2y^2 + 2z^2 = 4 once, traveling from outside the sphere to inside as t goes from -∞ to +∞.
The equation of the sphere is 2y^2 + 2z^2 = 4. To find the intersection points of the path and the sphere, we need to substitute the components of r(t) into the equation of the sphere:
2y^2 + 2z^2 = 4
2(e^(-t) cos t)^2 + 2e^2 = 4
2e^(-2t) cos^2(t) + 2e^2 = 4
e^(-2t) cos^2(t) + e^2 = 2
Multiplying both sides by e^(2t), we get:
cos^2(t) + e^(4t) = 2e^(2t)
We can rewrite this equation as:
e^(4t) - 2e^(2t)cos^2(t) + cos^2(t) - 1 = 0
This is a quadratic equation in e^(2t) with solutions:
e^(2t) = cos^2(t) ± sqrt(cos^4(t) - 4(cos^2(t) - 1))
We want to show that there is only one intersection point, which means we want to show that the discriminant of the quadratic is negative, i.e.:
cos^4(t) - 4(cos^2(t) - 1) < 0
Expanding the left-hand side, we get:
cos^4(t) - 4cos^2(t) + 4 < 0
Simplifying, we get:
(cos^2(t) - 2)^2 < 0
Since the square of a real number is always non-negative, this inequality has no real solutions. Therefore, the discriminant of the quadratic is negative, and there is only one intersection point.
To show that the path travels from outside the sphere to inside as t goes from -∞ to +∞, we can observe that as t goes from -∞ to +∞, the first component of r(t) goes from -∞ to +∞, while the second and third components oscillate between 0 and +∞. This means that the path starts outside the sphere (at the point (0, +∞, +∞)) and ends inside the sphere (at the point (+∞, 1, 1)). Therefore, the path must intersect the sphere once, traveling from outside to inside.

Answer:
The x-intercept of Line A is (-3, 0), and the x-intercept of Line B is (-1, 0). Therefore, the x-intercept of Line A is less than the x-intercept of Line B.
Step-by-step explanation:
The x-intercept of a graph or function is where the line hits the x-axis on a coordinate plane. In other words, the y-value of the x-intercept is 0. Since we are looking for the x-intercept of Line A, we can use the given equation to solve for it by inserting the value y = 0 (as mentioned above, the x-intercept of a function will have the y-value as 0). By solving the equation, you'll get that [tex]-2=\frac{1}{3} (x-3)[/tex] ⇒ [tex]-6=x-3[/tex] ⇒ [tex]x = -3[/tex]. Therefore, the x-intercept of Line A is (-3, 0).
The x-intercept on a graph is easier to find, as it is where the line touches the x-axis. So the x-intercept of Line B would be (-1, 0). Now that we have both x-intercepts, we can compare them and come up with the final answer that is required. As -3 is less than -1, we can conclude that the x-intercept of Line A is (-3, 0), and the x-intercept of Line B is (-1, 0). Therefore the x-intercept of Line A is less than the x-intercept of Line B.

This equation demonstrates the distributive property of multiplication
What is distributive property ?
In mathematics, the distributive property is a property of binary operations that applies to numbers, sets, or other mathematical objects. It governs how to perform the operation of multiplication over addition or subtraction. The distributive property states that for any numbers a, b, and c:
a × (b + c) = a × b + a × c (multiplication distributes over addition)
or
a × (b - c) = a × b - a × c (multiplication distributes over subtraction)
The property demonstrated in this equation is the distributive property of multiplication over addition. This property states that the product of a number and the sum of two or more numbers is equal to the sum of the products of the number and each of the individual numbers. In other words, a(b + c) = ab + ac.
In this case, 15 is being multiplied by the sum of 5 and 7, which is equivalent to multiplying 15 by 5 and 15 by 7 separately and adding the results. So, we have:
15(5 + 7) = 15 x 5 + 15 x 7

Step-by-step explanation:
To find f(x + h) we simply plug (x + h) into the function f(x), anywhere we see an x.
[tex]f(x) = x^{2} -5x+9\\f(x+h) = (x+h)^{2}-5(x+h)+9[/tex]
Now we can plug them into the fraction:
[tex]\frac{((x+h)^{2}-5(x+h)+9)-(x^{2} -5x+9)}{h}[/tex]
Expanding all of the terms, we get:
[tex]\frac{(x^{2} +2hx + h^{2} -5x-5h+9)-(x^{2} -5x+9)}{h}[/tex]
Distributing the negative we get:
[tex]\frac{x^{2} +2hx + h^{2} -5x-5h+9-x^{2} +5x-9}{h}[/tex]
Now we see that [tex]x^{2} -x^{2} ,-5x+5x,[/tex] and [tex]9-9[/tex] all cancel, leaving us with:
[tex]\frac{2hx + h^{2}-5h}{h}[/tex] (Notice the only terms left are those with h in them)
As every term contains an h, we can remove an h from every term, giving us:
2x + h - 5

The diagonal distance from the airplane to the runway is approximately 5230.8 ft.
What is Trigonometry?Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It is used to solve problems related to measurements of angles and distances.
The angle of depression of 18° is the angle between the airplane's line of sight and the horizontal line representing the runway. We can label the altitude of the airplane as 1560 ft:
Now we can use trigonometry to find the diagonal distance from the airplane to the runway. In particular, we can use the tangent function:
tan(18°) = opposite / adjacent
In this case, the opposite side is the altitude of the airplane (1560 ft), and the adjacent side is the diagonal distance we're trying to find (x). Therefore:
tan(18°) = 1560 / x
To solve for x, we can multiply both sides by x and then divide both sides by tan(18°):
x = 1560 / tan(18°)
Using a calculator, we find that:
x ≈ 5230.8 ft
Therefore, the diagonal distance from the airplane to the runway is approximately 5230.8 ft.
