s. The area of a regular hexagon is 384√3Cm². Find A. the side length of the hexagon B. the radius of the hexagon C. the apothem of the hexagon
The apothem of the hexagon is 8√3 cm.
We are given that;
The area of a regular hexagon= 384√3Cm²
Now,
To find the side length, radius, and apothem of a regular hexagon given its area, we can use the following formulas:
Area = (3√3 s^2) / 2 Area = (1/2) a P Area = (3/2) r a
where s is the side length, a is the apothem, P is the perimeter, and r is the radius of the hexagon. We can solve for any of these variables by rearranging the formulas and plugging in the given area.
A. To find the side length, we can use the first formula and solve for s:
s^2 = (2 Area) / (3√3) s = sqrt((2 Area) / (3√3))
Plugging in Area = 384√3, we get:
s = sqrt((2 * 384√3) / (3√3)) s = sqrt(256) s = 16
Therefore, the side length of the hexagon is 16 cm.
B. To find the radius, we can use any of the formulas and solve for r. For example, using the third formula, we get:
r = (2 Area) / (3 a)
To find a, we can use the second formula and solve for a:
a = (2 Area) / P
To find P, we can use the fact that P = 6s and plug in s = 16:
P = 6 * 16 P = 96
Plugging in P and Area into the formula for a, we get:
a = (2 * 384√3) / 96 a = 8√3
Plugging in a and Area into the formula for r, we get:
r = (2 * 384√3) / (3 * 8√3) r = 32
Therefore, the radius of the hexagon is 32 cm.
C. To find the apothem, we can use any of the formulas and solve for a. For example, using the second formula, we get;
a = (2 Area) / P
Plugging in Area = 384√3 and P = 96, we get:
a = (2 * 384√3) / 96 a = 8√3
Therefore, by polygon the answer will be 8√3 cm.

Required two transformations are translated according to the rule (x, y) → (x + 8, y + 2) reflected across the x-axis.
How to find the two transformations applied to pentagon ABCDE to create A″B″C″D″E″?
To find the two transformations applied to pentagon ABCDE to create A″B″C″D″E″, we can compare the coordinates of corresponding vertices of both pentagons.
Starting with point A, we see that it has been translated 8 units to the right and 2 units up to become A″. Therefore, the first transformation is a translation according to the rule (x, y) → (x + 8, y + 2).
Next, we can compare the y-coordinates of point A and A″ to see if a reflection has been applied. We see that the y-coordinate of A has changed from 5 to -7 in A″, indicating that a reflection has been applied across the x-axis.
Therefore, the two transformations applied to pentagon ABCDE to create A″B″C″D″E″ are:
Translated according to the rule (x, y) → (x + 8, y + 2)
Reflected across the x-axis.
The other options can be ruled out as they do not correctly reflect the transformation that was applied.

The height h of an object thrown from the top of a ski lift 1240 feet high after t seconds is h=-16t2 +32t+1240. For what times is the height of the object at least 1000 feet?
←
The height of the object is at least 1000 feet from seconds to seconds.
Check the picture below.
so the parabolic path of the object is more or less like the one shown below in the picture, now this object has an initial of 1240 ft, as it gets thrown from the ski lift, so from 0 seconds is already higher than 1000 feet.
\(h=-16t^2+32t+1240\hspace{5em}\stackrel{\textit{a height of 1000 ft}}{1000=-16t^2+32t+1240} \\\\\\ 0=-16t^2+32t+240\implies 16t^2-32t-240=0\implies 16(t^2-2t-15)=0 \\\\\\ t^2-2t-15=0\implies (t-5)(t+3)=0\implies t= \begin{cases} ~~ 5 ~~ \textit{\LARGE \checkmark}\\ -3 ~~ \bigotimes \end{cases}\)
now, since the seconds can't be negative, thus the negative valid answer in this case is not applicable, so we can't use it.
So the object on its way down at some point it hit 1000 ft of height and then kept on going down, and when it was above those 1000 ft mark happened between 0 and 5 seconds.
If 4 distinct balls are placed at random into 4 boxes, find the probability that exactly one box remains empty.
The probability that exactly one box remains empty = 9/16
Let us assume that b₁, b₂, b₃ and b₄ be four distinct balls and M₁, M₂, M₃ and M₄ are four boxes.
The total number of ways in which 4 different balls b₁, b₂, b₃ and b₄ can be placed in 4 distinct boxes would be,
n = 4⁴
And the number of ways to choose an empty box = ⁴C₁
The four balls must be distributed to the remaining 3 boxes so that no box is left empty. This means means one of those three boxes will receive two balls and the others will each receive one. There are ³C₁ ways to choose the box that will receive two balls and ⁴C₂ ways to choose which two balls will be placed in that box. The remaining balls can be placed in the remaining two boxes in 2! ways.
So, the number of ways that exactly one box remains empty
= ⁴C₁ × ³C₁ × ⁴C₂ × 2!
= 144

Two different students decide to compare their businesses. Scooter makes his own t-shirts,
while Karissa does computer repairs. For both models, x represents the number of sales made
each month and f(x) represents total money for each individual. The two functions below model
their respective businesses:
Scooter: f(x) = 200 + 15x
Karissa: f(x) = 80 + 35x
a. Describe what the slope and y intercept represent for both models based on the context.
Compare the two functions. What is one statement you could say about each?
b.
C.
In one month, Scooter sells 20 shirts. That same month, Karissa does 12 repairs. Who had
the better month?
a) Comparing the two functions, Scooter's business has a lower slope of 15 compared to Karissa's business with a slope of 35. b) Both Scooter and Karissa earned a total of $500 in that month. Therefore, they had an equal month in terms of total money earned.
How to Describe what the slope and y intercept represent for both models based on the contexta) In the context of Scooter's business, the slope of the function f(x) = 200 + 15x represents the rate at which the total money earned increases with each additional sale. Each unit increase in x (number of sales) results in an increase of $15 in total money earned. The y-intercept of 200 represents the initial amount of money Scooter already had before making any sales.
In the context of Karissa's business, the slope of the function f(x) = 80 + 35x represents the rate at which the total money earned increases with each additional repair job. Each unit increase in x (number of repairs) results in an increase of $35 in total money earned. The y-intercept of 80 represents the initial amount of money Karissa already had before doing any repair jobs.
Comparing the two functions, Scooter's business has a lower slope of 15 compared to Karissa's business with a slope of 35. This means that Karissa's business earns more money per repair job compared to Scooter's business per t-shirt sale.
b) To determine who had the better month, we need to calculate the total money earned by each individual based on the given sales/repairs.
For Scooter, with x = 20 (number of shirts sold):
f(x) = 200 + 15x
f(20) = 200 + 15 * 20
f(20) = 200 + 300
f(20) = 500
For Karissa, with x = 12 (number of repairs):
f(x) = 80 + 35x
f(12) = 80 + 35 * 12
f(12) = 80 + 420
f(12) = 500
Both Scooter and Karissa earned a total of $500 in that month. Therefore, they had an equal month in terms of total money earned.

Transformation is the process of changing one form or structure into another. Here are some key points about transformation:
• Physical transformations involve changing the physical properties of an object, like shape, size, state of matter, etc. Some examples are cutting, bending, melting, freezing, dissolving, combining substances, etc.
• Chemical transformations involve changing the chemical composition of a substance, forming new substances with different properties. Some examples are chemical reactions that produce new compounds, oxidation reactions, decomposition, synthesis reactions, etc.
• Biological transformations occur within living organisms through processes like development, growth, metabolism, adaptation, and evolution. These changes occur over time and at the cellular or molecular level.
• Mathematical transformations involve applying operations or functions to mathematical objects like numbers, vectors, matrices, etc. to produce new outputs. Common transformations include translation, rotation, reflection, scaling, and projection.
• Information transformations occur when data is manipulated, organized, or changed. Examples are data compression, encryption, encoding, classification, and filtering of information.
• Conceptual transformations refer to changes in a person's knowledge, understanding, perspectives, beliefs, attitudes, or behavior. Things like experiences, education, and realizations can cause conceptual transformations.
The key aspects of any transformation are that there is an initial state or form that undergoes some change process resulting in an altered final state or form. There are often changes to properties, composition, structure, or relationships involved.
Hope this explanation of transformation helps! Let me know if you have any other questions.
Transformation can refer to a marked change in form, nature, or appearance. It can also refer to a process by which one figure, expression, or function is converted into another one of similar value.

Step-by-step explanation:
A kite is a flying object consisting of a frame made of light materials, such as bamboo or plastic, covered in
paper or cloth, and flies with a string attached. The shape of a kite and the way it flies can be modeled using
a system of linear equations, which describe the relationships between variables in a mathematical model. In
this case, the variables might represent the lift and drag forces on the kite, the angle of the kite string, and
the wind speed and direction. By solving the system of linear equations, engineers and scientists can
understand how the kite will behave under different conditions and make predictions about its performance.
Answer the following.
1. A kite manufacturer produces two types of kites: standard and deluxe. The standard kite requires 2
meters of fabric and 5 meters of string, while the deluxe kite requires 3 meters of fabric and 7 meters
of string. If the manufacturer has 200 meters of fabric and 450 meters of string, how many of each
type of kite can they produce to maximize their profit?
The number of each kite the manufacturer can produce to maximize profit are;
90 standard kites or 64 deluxe kites
What is profit maximization?Profit maximization is a process used to increase the profit of a company to the highest levels.
Let x represent the number of standard kite produced and let y represent the number of deluxe kite produced. Let p represent the profit from selling one standard kite and let q represent the profit from selling one deluxe kite.
The constraints inequalities that can be obtained to solve the question using linear programming methodology are therefore;
2·x + 3·y ≤ 200 (The fabric constraints)
5·x + 7·y ≤ 450 (The string constraints)
x ≥ 0, y ≥ 0 (Non–negative constraints)
The objective function which is the total profit can be presented as follows;
z = p·x + q·y (total profit)
Therefore, we get;
Maximize: z = p·x + q·y
Subject to:
2·x + 3·y ≤ 200
5·x + 7·y ≤ 450
x ≥ 0, y ≥ 0
The graph of the above inequalities indicates that we get the following coordinates of the vertices of the feasible region;
(0, 64 2/7), (90, 0), (0, 0)
The objective function indicates that we get;
z(0, 64 2/7) = p × 0 + q × 64 2/7 = (64 2/7)·q
z(90, 0) = p × 90 + q × 0 = p × 90 = 90·p
z(0, 0) = p × 0 + q × 0 = 0

Step-by-step explanation:
I assume AB is supposed to be a straight line. yes ?
in that case please remember that all angles on top of a line (and then again below a line) must sum up to 180 degrees (this is what it takes to flip a "stick" on that line from left to right).
so, COD covers already 90 degrees of these 180.
that means AOD + BOC = 180 - 90 = 90 degrees.
now we know that the 2 angles are in the ratio of 1:5.
that means that BOC is 5 times as large as AOD.
and we can be more direct :
since the 2 angles are in the ratio 1:5 we are actually splitting the remaining 90 degrees into 6 parts (5+1).
and BOC gets then 5 of these 6 parts, and AOD gets the remaining 1 part.
so,
90/6 = 15
therefore, one of these parts is 15 degrees.
so, we know AOD = 15 degrees.
BOC = 5×15 = 75 degrees
or simply 90 - 15 = 75 degrees

Lee watches TV for 3 hours per day. During that time, the TV consumes 250 watts per hour. Electricity costs (18 cents)/(1 kilowatt-hour). How much does Lee's TV cost to operate for a month of 30 days?
Lee's TV costs $4.05 to operate for a month of 30 days.
To calculate the cost of operating Lee's TV for a month, we need to find out the total number of kilowatt-hours (kWh) of electricity consumed by the TV during that time.
First, let's find out how many watts Lee's TV consumes in a day:
250 watts/hour x 3 hours/day = 750 watts/day
To convert this to kilowatts, we divide by 1000:
750 watts/day ÷ 1000 = 0.75 kilowatts/day
Now, we can calculate the total number of kilowatt-hours consumed by the TV in a month:
0.75 kilowatts/day x 30 days = 22.5 kilowatt-hours
Finally, we can calculate the cost of operating the TV for a month:
22.5 kilowatt-hours x 18 cents/kilowatt-hour = $4.05
