A regular polygon inscribed in a circle can be used to derive the formula for the area of a circle. The polygon area can be expressed in terms of the area of a triangle. Let s be the side length of the polygon, let r be the hypotenuse of the right triangle, let h be the height of the triangle, and let n be the number of sides of the regular polygon. Polygon area = n(12sh).
Answers
Here, we let n be the number of sides of the regular polygon. Polygon area = n(12sh). As n increases, h approaches r so that rh approaches r² and hence, this statement is true. So, option 4 is the correct option.
When ns equals circumference or 2r, the polygon will turn into a circle.
A polygon must be converted into a circle.
Let s represent the polygon's side length, r represent the hypotenuse of the right triangle,
Let n be the regular polygon's number of sides and h be the height of the triangle.
The polygon's area is now specified as polygon area = n(1/2sh).
Now, we must suppose that the polygon's sides are infinite in order to obtain a circle. In order to do this, we must assume that the polygon's perimeter is the same as the circle's perimeter.
That's why when the number of sides of the polygon will increase its perimeter will become closer to 2πr and its area will become close to a circle.

Answer:
Customers are charged $0.003 per gallon of water used.
Step-by-step explanation:
In the given function, T = 35 + 0.003w, the coefficient of w (which is 0.003) represents the rate at which the total cost (T) increases per unit increase in the amount of water used (w). In other words, it is the cost per gallon of water used.
Therefore, the slope of the function is 0.003, and it represents the rate of change of the cost with respect to the amount of water used. Each additional gallon of water used will increase the monthly bill by $0.003.

Answers
If Precision Engineering Factory consumes 12,500 units of a component in every three- month period. the total cost of material is TZS 6,060 per year.
How to find the total cost of material?The annual demand for the material can be calculated as follows:
Annual demand = (12,500 units/3 months) x (4 quarters/year) = 50,000 units/year
Ordering cost = TZS 3 per order
Number of orders = (50,000 units/year) / (12,500 units/order) = 4 orders/year
Ordering cost per year = (4 orders/year) x (TZS 3/order) = TZS 12/year
Trucking cost = TZS 12 per order
Trucking cost per year = (4 orders/year) x (TZS 12/order) = TZS 48/year
Deterioration and obsolescence cost = TZS 0.04 per unit per year
Deterioration and obsolescence cost per year = (50,000 units/year) x (TZS 0.04/unit/year) = TZS 2,000/year
Interest cost = TZS 0.06 per unit per year
Interest cost per year = (50,000 units/year) x (TZS 0.06/unit/year) = TZS 3,000/year
Storage cost = TZS 1,000 per year for 50,000 units
Storage cost per unit per year = (TZS 1,000/year) / (50,000 units) = TZS 0.02/unit/year
Storage cost per year = (50,000 units/year) x (TZS 0.02/unit/year) = TZS 1,000/year
Total cost of material = Ordering cost + Trucking cost + Deterioration and obsolescence cost + Interest cost + Storage cost
Total cost of material = TZS 12/year + TZS 48/year + TZS 2,000/year + TZS 3,000/year + TZS 1,000/year
Total cost of material = TZS 6,060/year
Therefore, the total cost of material is TZS 6,060 per year.

Answers
We know the lengths of the sides opposite and adjacent to angle A, as well as the length of the hypotenuse, then sin(A) = 9/41 and cos(A) = 40/41.
What are trigonometric ratios?
Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle. The basic trigonometric ratios are sin, cos, and tan, namely sine, cosine, and tangent ratios.
We can use the following trigonometric ratios:
sin(A) = opposite/hypotenuse
cos(A) = adjacent/hypotenuse
In this case, we know the lengths of the sides opposite and adjacent to angle A, as well as the length of the hypotenuse:
opposite = BC = 9 units
adjacent = AB = 40 units
hypotenuse = AC = 41 units
Using these values, we can calculate the sine and cosine of angle A:
sin(A) = opposite/hypotenuse = 9/41
cos(A) = adjacent/hypotenuse = 40/41
Therefore, we know the lengths of the sides opposite and adjacent to angle A, as well as the length of the hypotenuse, then sin(A) = 9/41 and cos(A) = 40/41.

For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.

A) x = - 4, -3
B) x= 4, 14
C) x= -3, 4
D) x= -3, -7
Answers
Answer:
C
Step-by-step explanation:
x + y + 10 = 0 ( subtract x + 10 from both sides )
y = - x - 10 → (1)
x² + y - 2 = 0 → (2)
substitute y = - x - 10 into (2)
x² - x - 10 - 2 = 0
x² - x - 12 = 0 ← in standard form
(x - 4)(x + 3) = 0 ← in factored form
equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 4 = 0 ⇒ x = 4

Answers
Answer:
Step-by-step explanation:
Pour trouver la forme standard de l'équation d'une ellipse à partir des extrémités des grands axes et des petits axes, nous pouvons utiliser les formules suivantes:
Le centre de l'ellipse est le point (h, k), où h est la moyenne des coordonnées x des extrémités des grands axes et k est la moyenne des coordonnées y des extrémités des petits axes. Donc,
h = (2 + 8) / 2 = 5
k = (3 + 1) / 2 = 2
Donc, le centre de l'ellipse est (5, 2).
La distance a est la moitié de la longueur du grand axe, donc
a = (8 - 2) / 2 = 3
La distance b est la moitié de la longueur du petit axe, donc
b = (3 - 1) / 2 = 1
Maintenant, nous pouvons utiliser ces valeurs pour écrire l'équation de l'ellipse en forme standard:
(x - h)^2 / a^2 + (y - k)^2 / b^2 = 1

(a) The probability that exactly 10 of the first 15 graded projects are from the second section can be calculated using the binomial probability formula:
P(X = 10) = (15 choose 10) * (35/60)^10 * (25/60)^5 = 0.0361
(b) The probability that at least 10 of the first 15 graded projects are from the second section can be calculated by summing the probabilities for 10, 11, 12, 13, 14, and 15:
P(X >= 10) = P(X = 10) + P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14) + P(X = 15) = 0.0361 + 0.0132 + 0.0035 + 0.0007 + 0.0001 + 0.0000 = 0.0536
(c) The probability that at least 10 of the first 15 graded projects are from the same section can be calculated by summing the probabilities for 10, 11, 12, 13, 14, and 15 from both sections:
P(X >= 10) = P(X = 10) + P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14) + P(X = 15) = 0.0361 + 0.0132 + 0.0035 + 0.0007 + 0.0001 + 0.0000 + 0.0019 + 0.0003 + 0.0000 + 0.0000 + 0.0000 + 0.0000 = 0.0556
(d) The mean value and standard deviation of the number among these 15 that are from the second section can be calculated using the formulas for the mean and standard deviation of a binomial distribution:
mean = np = 15 * (35/60) = 8.75
standard deviation = sqrt(np(1-p)) = sqrt(15 * (35/60) * (25/60)) = 1.568

What is Volume?The space that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
To find the volume of the sidewalk in cubic feet, we first need to convert the dimensions to feet. Since 1 foot = 12 inches, we have:
Length = 24 feet + 6 inches = 24.5 feet
Width = 4 feet + 6 inches = 4.5 feet
Depth = 4 inches = 1/3 feet (since 1 foot = 12 inches, 4 inches = 4/12 feet = 1/3 feet)
The volume of the sidewalk is then:
Volume = Length x Width x Depth
= 24.5 feet x 4.5 feet x 1/3 feet
= 3.25 cubic feet
Since one bag of concrete mix makes 0.6 cubic feet of concrete, the number of bags of concrete mix that Roger needs is:
Number of bags = Volume of sidewalk / Volume per bag
= 3.25 cubic feet / 0.6 cubic feet per bag
= 5.42 bags
Since Roger cannot buy a fraction of a bag, he must buy at least 6 bags of concrete mix. Therefore, the least whole number of bags of concrete mix that Roger needs is:

Graph appears to intersect the X axis in between 20 and 22 and algebraically the estimate of zero is 21.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Given a linear function which represents the profit of Bethany, y after x hours of dog walking.
(a) From the graph, we have to estimate the zero.
The graph seems to intersect the X axis in between 20 and 22, approximately 21.
(b) To solve this algebraically, we have the profit function,
y = 23x - 480
When y = 0,
23x - 480 = 0
23x = 480
x = 20.87 ≈ 21
Hence the graphical method gives the same estimate as the algebraic method.

How to solve Linear Equations?
We are given the linear equation;
4x - x = 0
From the linear equation above, seeing that we have an x that is raised to the power of one-third, and we have a single x variable, the first step would be to add x to both sides to get;
The first step to solving the equation is to; C. add x to both sides
The second step to solving the equation is to; C. cube both sides
Solving the equation for x initially yields; C. two possible values
Checking the solutions shows that; D. none are valid solutions
4x - x + x = 0 + x
4x = x
Now, to remove the fraction root, what we will now do as the second step is to cube both sides to get;
(4x)³ = x³
4³x = x³
64x = x³
Divide both sides by x to get;
x² = 64
Take square root of both sides to get;
x = ±√64
x = ±8
Hence, The maximum possible value of the result is 8.

length of arc = radius x angle in radians
In this case, the radius is 6 and the angle measures 5π/6 radians, so the length of the intercepted arc is:
length of arc = 6 x 5π/6
= 5π
Therefore, the length of the intercepted arc is 5π, in simplest form.
Answer:
5pi (use the pi character button on your screen)
Step-by-step explanation:
Arc length formula is the shortest formula in all of all math!
Arc length = r•theta
r is the radius. In your question, it is 6.
"theta" is the angle in radians, which was given in your question as 5pi/6.
Fill in these given values to the formula.
Arc length
= r • theta
= 6 • 5pi/6
Simplify (the 6's cancel)
= 5pi
Which of the following equations has no real solutions?
OA. 10(x-6) = 10x - 60
OB.10(x+6)= 10(x + 10)
OC. 10x-6=60x-6
OD. 10x-610x6
Answers
Answer:
10x-610x6
The equation 10x-610x6 has no real solutions because it cannot be solved for any value of x. The left side of the equation is 10x-6, and the right side is 10x+6. Since the left side is greater than the right side, no value of x can make the equation true.

Answers
The point that is a solution to the system of inequalities y < −2x + 10 and y < 1/2x − 2 is point E at (4, -2). This is because point E satisfies both inequalities.
When we plug in the x and y values of point E into the first inequality, we get -2 < -2(4) + 10, which simplifies to -2 < 2, which is true.
When we plug in the x and y values of point E into the second inequality, we get -2 < 1/2(4) - 2, which simplifies to -2 < 0, which is also true. Therefore, point E is a solution to the system of inequalities.
For question 7, the correct answer is −10 < x < 35 and 0 < y ≤ 38. This is because the temperature must be between -10 and 35 degrees, and there must be between 0 and 38 people on the trip.
For question 8, the correct answer is 2x + 3y < 60. This is because a small rug requires 2 hours for dyeing and a medium-size rug requires 3 hours for dyeing, and the total time must be less than 60 hours.
For question 9, the correct answer is the graph with a dashed line f of x rising left to right that is shaded above and a dashed line that is falling g of x left to right that is shaded above.
This is because the solution to the system of inequalities is the area where both inequalities are true, which is the area where they have shading in common. In this case, it is the area above both dashed lines.
