Do the side lengths 6, 6, and 14 form a triangle? Explain. Support your explanation with drawings
The third side cannot connect to complete the triangle, we can conclude that the side lengths 6, 6, and 14 do not form a triangle.
What is the triangle inequality theorem?
The triangle inequality theorem states that the sum of the length of two sides must be greater than the length of the third side of that triangle.
No, the side lengths 6, 6, and 14 do not form a triangle.
To see why, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, if we add the two shorter sides 6 and 6, we get 12, which is less than the length of the longest side 14.
Therefore, the three side lengths cannot form a triangle.
We can also visualize this by trying to draw a triangle with sides of length 6, 6, and 14.
If we draw two equal-length sides of 6 units each and try to connect them with a third side of length 14 units, we will see that the third side is too long and cannot connect to form a triangle.
See the following diagram for an illustration in the attached image.
Hence, the third side cannot connect to complete the triangle, we can conclude that the side lengths 6, 6, and 14 do not form a triangle.

Research Report:
Title: The Number of Coins Carried by Teachers
Introduction:
This research report aims to investigate the number of coins carried by teachers. The study seeks to understand the reasons behind carrying coins and whether there are any patterns or correlations between the number of coins and certain factors such as age, gender, and occupation.
The data was collected through a survey distributed among teachers from various educational institutions. The findings of this study provide insights into teachers' habits and preferences when it comes to carrying coins.
Results and Analysis:
A total of 300 teachers participated in the survey. The data revealed that the majority of teachers (60%) carry less than 5 coins, while 25% carry between 5 and 10 coins. Only a small percentage (15%) reported carrying more than 10 coins.
Further analysis based on demographic factors indicated that age and occupation had a significant influence on the number of coins carried. Older teachers were more likely to carry fewer coins, with 70% of teachers above the age of 50 carrying less than 5 coins.
Additionally, primary school teachers tended to carry more coins compared to secondary school teachers.
Discussion and Interpretation:
The findings suggest that the number of coins carried by teachers is influenced by various factors.
Teachers may carry coins for a range of reasons, such as purchasing small items, providing change for students, or utilizing vending machines.
The lower number of coins carried by older teachers could be attributed to a shift towards digital payment methods or a preference for carrying minimal cash.
The discrepancy between primary and secondary school teachers could be due to differences in daily activities and responsibilities.
This research provides valuable insights into the habits and preferences of teachers regarding the number of coins they carry.
Understanding these patterns can assist in designing more efficient payment systems within educational institutions and potentially guide the development of tailored financial solutions for teachers.
Further research could explore the reasons behind carrying coins in more depth and investigate how the digitalization of payments affects teachers' behavior in different educational contexts.

Find the points on the given curve where the tangent line is horizontal or vertical. (Assume 0 ≤ θ ≤ 2π. Enter your answers as a comma-separated list of ordered pairs.) r = 1 − sin(θ) horizontal tangent
The tangent to the curve at a point P (x, y) has slope dy/dx at that point. By the chain rule,
dy/dx = (dy/dθ) / (dx/dθ)
We're in polar coordinates, so
y (θ) = r (θ) sin(θ) ==> dy/dθ = dr/dθ sin(θ) + r (θ) cos(θ)
x (θ) = r (θ) cos(θ) ==> dx/dθ = dr/dθ cos(θ) - r (θ) sin(θ)
We're given r (θ) = 1 - sin(θ), so that
dr/dθ = -cos(θ)
Then the slope of the tangent to the curve at P is
dy/dx = (dr/dθ sin(θ) + r (θ) cos(θ)) / (dr/dθ cos(θ) - r (θ) sin(θ))
dy/dx = (-cos(θ) sin(θ) + (1 - sin(θ)) cos(θ)) / (-cos²(θ) - (1 - sin(θ)) sin(θ))
dy/dx = - (cos(θ) - sin(2θ)) / (sin(θ) + cos(2θ))
The tangent is horizontal if dy/dx = 0 (or when the numerator vanishes):
cos(θ) - sin(2θ) = 0
cos(θ) - 2 sin(θ) cos(θ) = 0
cos(θ) (1 - 2 sin(θ)) = 0
cos(θ) = 0 or 1 - 2 sin(θ) = 0
cos(θ) = 0 or sin(θ) = 1/2
[θ = π/2 + 2nπ or θ = 3π/2 + 2nπ] or [θ = π/6 + 2nπ or θ = 5π/6 + 2nπ]
where n is any integer.
In the interval 0 ≤ θ ≤ 2π, we get solutions of θ = π/6, θ = 5π/6, and θ = 3π/2. (We omit π/2 because the denominator is zero at that point and makes dy/dx undefined.) So the points where the tangent is horizontal are themselves (√3/4, 1/4), (-√3/4, 1/4), and (0, -2), respectively.
The tangent is vertical if 1/(dy/dx) = 0 (or when the denominator vanishes):
sin(θ) + cos(2θ) = 0
sin(θ) + (1 - 2 sin²(θ)) = 0
2 sin²(θ) - sin(θ) - 1 = 0
(2 sin(θ) + 1) (sin(θ) - 1) = 0
2 sin(θ) + 1 = 0 or sin(θ) - 1 = 0
sin(θ) = -1/2 or sin(θ) = 1
[θ = 7π/6 + 2nπ or θ = 11π/6 + 2nπ] or [θ = π/2 + 2nπ]
Then for 0 ≤ θ ≤ 2π, the tangent will be vertical for θ = 7π/6 and θ = 11π/6, which correspond respectively to the points (-3√3/4, -3/4) and (3√3/4, -3/4). (Again, we omit π/2 because this makes dy/dx non-existent.)

A company produced in the first quarter 6,905 pieces in the second quarter the same company produced 795 pieces more than in the first quarter under these conditions how many pieces did the company produce in the first semester?
Answer: 14,605 pieces.
Step-by-step explanation:
In the second quarter, the company produced 795 pieces more than in the first quarter.
So, the total pieces produced in the second quarter can be calculated as:
6905 + 795 = 7700
The total pieces produced in the first semester (two quarters) can be calculated as:
6905 + 7700 = 14,605
Therefore, the company produced 14,605 pieces in the first semester.
The number of pieces the company produced in the first semester was 14,605 pieces.
How many?The question asks to calculate how many pieces a company produced in the first semester, considering the production of two quarters.
In the first quarter, the company produced 6,905 pieces, as indicated in the question.
Already in the second quarter, the company produced 795 more pieces than in the first quarter, which means that the production in the second quarter was:
6,905 + 795 = 7,700 pieces.
To know the company's total production in the first semester, just add the productions of the two quarters:
6,905 + 7,700 = 14,605 pieces

If Susan will be 2 times old in seven years as she was 3 years ago, what is Susan's present age?
Answer:
Let's start by assigning a variable to Susan's present age. Let's call it "x".
According to the problem, in seven years, Susan will be "x + 7" years old.
Three years ago, Susan was "x - 3" years old.
The problem tells us that Susan will be 2 times as old in seven years as she was 3 years ago. So we can set up the following equation:
x + 7 = 2(x - 3)
Now we can solve for x:
x + 7 = 2x - 6
x = 13
Therefore, Susan's present age is 13 years old.
Let's assume Susan's present age is "x" years. According to the information provided, "Susan will be 2 times old in seven years as she was 3 years ago."
Seven years from now, Susan's age would be x + 7, and three years ago, her age would have been x - 3. According to the given statement, her age in seven years will be two times her age three years ago:
x + 7 = 2(x - 3)
Let's solve this equation to find Susan's present age:
x + 7 = 2x - 6
Subtracting x from both sides:
7 = x - 6
Adding 6 to both sides:
13 = x
Therefore, Susan's present age is 13 years.

An equal sign ("=") links two expressions together to form an equation. The two expressions on each side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.
It is given that, A man is three times as old as his daughter. If the difference in their ages is 36 years,
We have to find the ages of the father and daughter.
Suppose the age of the father and daughter will be x and y respectively.
If the man is three times as old as his daughter,
x = 3y
If the difference in their ages is 36 years
x - y = 36
Put the value of x as,
3y -y = 36
2y = 36
y = 18
x = 54
Thus, if a man has a daughter who is three times his age. The father and daughter will be 54 and 18, respectively, assuming their ages are 36 years distant.

Hi can someone please help me solve the following system of inequalities and state the coordinates in the solution setz
The graph of the system of the inequalities is attached.
To graph the inequalities y < -x - 4 and y ≥ (3/5)x + 4, we can start by graphing the corresponding equations and then shade the appropriate regions based on the inequality signs.
Let's begin with the equation y = -x - 4:
Choose a range of x-values to plot.
For simplicity, let's use x-values from -10 to 10.
Substitute different x-values into the equation to find corresponding y-values.
For example:
When x = -10, y = -(-10) - 4 = 10 - 4 = 6.
When x = 0, y = -(0) - 4 = -4.
When x = 10, y = -(10) - 4 = -10 - 4 = -14.
Plot these points on the coordinate plane and draw a straight line passing through them.
This line represents the equation y = -x - 4.
Next, let's graph the equation y = (3/5)x + 4:
Again, choose a range of x-values to plot. Let's use the same range of -10 to 10.
Substitute different x-values into the equation to find corresponding y-values. For example:
When x = -10, y = (3/5)(-10) + 4 = -6 + 4 = -2.
When x = 0, y = (3/5)(0) + 4 = 0 + 4 = 4.
When x = 10, y = (3/5)(10) + 4 = 6 + 4 = 10.
Plot these points on the coordinate plane and draw a straight line passing through them.
This line represents the equation y = (3/5)x + 4.
Now, let's shade the regions based on the inequalities:
For y < -x - 4, we need to shade the region below the line y = -x - 4.
For y ≥ (3/5)x + 4, we need to shade the region above or on the line y = (3/5)x + 4.
Hence, the region where the shaded regions overlap represents the solution to both inequalities.

Let C(x) represent the cost of producing x items and p(x) be the sale price per item if x items are sold. The profit P(x) of selling x items is P(x)=x p(x)-C(x) (revenue minus costs). The average profit per item when x items are sold is P(x)/x and the marginal profit is dP/dx. The marginal profit approximates the profit obtained by selling one more item given that x items have already been sold. Consider the following cost functions C and price functions p. Complete partsâ (a) throughâ (d) below.
a. Find the profit function P.
b. Find the average profit function and marginal profit function.
c. Find the average profit and marginal profit if x=a units are sold.
d. Interpret the meaning of the values obtained in part (c).
C(x)=â0.02x^2 +50x+100, p(x)=100, a=500
Answer:
\((a)\) \(P(x) = 0.02x^2 +50x - 100\)
\((b)\) \(Average = 0.02x + 50 - \frac{100}{x}\) and \(Marginal = 0.04x + 50\)
\((c)\) \(Average = 59.8\) and \(Marginal = 70\)
(d) See Explanation
Step-by-step explanation:
Given
\(p(x) = 100\)
\(C(x) = -0.02x^2 +50x +100\)
Solving (a) Profit function; P(x)
\(P(x) = xp(x) - C(x)\)
This gives:
\(P(x) = x*100 - (-0.02x^2 + 50x + 100)\)
\(P(x) = 100x + 0.02x^2 - 50x - 100\)
Collect like terms
\(P(x) = 0.02x^2 - 50x +100x - 100\)
\(P(x) = 0.02x^2 +50x - 100\)
Solving (b): Average profit function and Marginal profit function
\(Average = \frac{P(x)}{x}\)
This gives:
\(Average = \frac{0.02x^2 + 50x - 100}{x}\)
Break down the fraction
\(Average = \frac{0.02x^2}{x} + \frac{50x}{x} - \frac{100}{x}\)
\(Average = 0.02x + 50 - \frac{100}{x}\)
\(Marginal = \frac{dP}{dx}\)
\(P(x) = 0.02x^2 +50x - 100\)
Differentiate
\(\frac{dP}{dx} = 2 * 0.02x + 50 - 0\)
\(\frac{dP}{dx} = 0.04x + 50\)
Hence:
\(Marginal = 0.04x + 50\)
Solving (c): Average profit and Marginal profit if x = a
\(a = 500\)
So:
\(x =500\)
Substitute 500 for x
\(Average = 0.02x + 50 - \frac{100}{x}\)
\(Average = 0.02 * 500 + 50 - \frac{100}{500}\)
\(Average = 59.8\)
\(Marginal = 0.04x + 50\)
\(Marginal = 0.04*500 + 50\)
\(Marginal = 70\)
Solving (d): Interpret the values in (c)
\(Average = 59.8\)
They make a profit of 59.8 for the first 500 items
\(Marginal = 70\)
From the 501st item, the profit is 70

y=-3 sin(2x) is the equation has a maximum at (0, –1) and a minimum at ( pi Over 3, negative 5)
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given,
We need to use the sliders to change the values of a, b, c, and d in the cosine function.
We need to find the equation which has maximum at (0, –1) and a minimum at (pi Over 3, negative 5)).
While doing slider problems we have to set the values as set a to -3, set b to 2 and keep c at 0.
y=-3 sin(2x) is the answer and the equation from the sliders should match the answer.
Hence y=-3 sin(2x) is the equation has a maximum at (0, –1) and a minimum at ( pi Over 3, negative 5)
