The value of x that makes the unshaded area equal to the shaded area is 7.07 inches.

An equation is an expression that shows the relationship between two or more variables and numbers.

The area of big sector = (60/360) * π(10)² = (50π /3) cm²

Area of small sector = (60/360) * π(x)² = (x²π /6) cm²

Unshaded area = (x²π /6) cm²

Shaded area = (50π /3) - (x²π /6) = (100π - x²π) /6

Shaded area = unshaded area

(100π - x²π) /6 = (x²π /6) cm²

x = 7.07

The length of x in the sector is 7.08 cm.

area of a sector = ∅ / 360 × πr²

where

Therefore,

area of a sector = 60 / 360 × π × 10²

area of a sector = 60 / 360 × π × 100

area of a sector = 6000 / 360 π

Hence,

area of the unshaded portion = 6000 / 360 π ÷ 2 = 6000π / 720 =  26.1666666667 = 26.2 cm

Hence,

26.2 = 60 / 360 × 3.14 × x²

x² = 26.2 / 0.52333333333

x = √50.0637261552

The value of u​ = 56.78 degree

Any triangle's three angles sum up to 180 degrees when added together. Therefore, the sum of angles A, B, and C is 180 degrees. Any triangle in the field of geometry has this property. This concept can be used to determine the measure of an angle or angles in which the degree measure is absent or not provided.

A, B, and C is 180 degrees

in a triangle <u- 40 degree <u+50 degree so <u is

<u- 40 degree

<u+50 degree

so

<u =

(u - 40 ) + (u+50 ) + u = 180

A new sample size of at least 537 fish to estimate the true mean length with a margin of error of 0.5 centimeters and 95% confidence.

To determine the size of a new sample so that the true mean length is estimated with a margin of error of 0.5 centimeters with 95% confidence, we need to find the standard error of the mean and use it in the formula for the margin of error.

The formula for the margin of error is: ME = z * (σ/√n)

where z is the z-score corresponding to the desired confidence level, σ is the standard deviation of the population, and n is the sample size.

We can estimate the standard deviation of the population using the sample variance, which is given as 34.9.

The standard deviation is the square root of the variance, so σ = √34.9

= 5.91.

To find the standard error of the mean, we divide the standard deviation by the square root of the sample size:

SEM = σ/√n

= 5.91/√n We want the margin of error to be 0.5 centimeters, so we can set up the equation:

0.5 = z * (5.91/√n)

To solve for n, we need to know the value of z for a 95% confidence level.

This corresponds to a z-score of 1.96. Substituting this into the equation gives: 0.5 = 1.96 * (5.91/√n)

Simplifying and solving for n gives: √n = 1.96 * (5.91/0.5) √n

n =(23.18)

n = 537

The amount of total cost at q* is 1.

To determine the production level that minimizes total cost, we need to find the value of q (production level) at which the derivative of the total cost function TC(q) is equal to zero. Let's begin by finding the derivative of TC(q):

TC(q) = 10 - 6q + q^2

To find the minimum point, we differentiate TC(q) with respect to q:

d(TC(q))/dq = -6 + 2q

Setting the derivative equal to zero and solving for q:

-6 + 2q = 0

2q = 6

q = 3

So the production level q* that minimizes the total cost is 3.

To find the amount of total cost at q*, we substitute q = 3 into the total cost function TC(q):

TC(q*) = 10 - 6(3) + (3)^2

TC(q*) = 10 - 18 + 9

TC(q*) = 1

Therefore, the amount of total cost at q* is 1.

Let's start with proving that side AB is parallel to side CD

First off, let's find the slope of line AB. So we'll use the slope formula.

\(A = (x_1,y_1) = (2,-1)\\\\B = (x_2,y_2) = (1,3)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{3 - (-1)}{1 - 2}\\\\m = \frac{3 + 1}{1 - 2}\\\\m = \frac{4}{-1}\\\\m = -4\\\\\)

The slope of AB is -4.

Now let's find the slope of line CD.

\(C = (x_1,y_1) = (6,5)\\\\D = (x_2,y_2) = (7,1)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{1 - 5}{7 - 6}\\\\m = \frac{-4}{1}\\\\m = -4\\\\\)

The slope of CD is also -4.

Recall that parallel lines always have equal slope (but different y intercepts).

This proves that AB is parallel to CD.

--------------------------

We'll follow the same steps to show that AD is parallel to BC.

Find the slope of AD

\(A = (x_1,y_1) = (2,-1)\\\\D = (x_2,y_2) = (7,1)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{1 - (-1)}{7 - 2}\\\\m = \frac{1 + 1}{7 - 2}\\\\m = \frac{2}{5}\\\\\)

Now find the slope of BC

\(B = (x_1,y_1) = (1,3)\\\\C = (x_2,y_2) = (6,5)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{5 - 3}{6 - 1}\\\\m = \frac{2}{5}\\\\\)

We get 2/5 each time, so these lines are parallel as well.

In short, the first section shows that AB is parallel to CD. The second section proved that AD is parallel to BC.

Because we have two pairs of parallel opposite sides, we can say that ABCD is a parallelogram.

So, your first move should be to remove a number of sticks that is less than or equal to 21, but also leaves your opponent with 4 sticks or more. This will set you up for success in the game.

The first few numbers in the Fibonacci sequence are: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, and so on. To determine the number of sticks a player can remove, they look at the previous two numbers in the sequence and add them together. For example, if the previous two numbers were 3 and 5, the player could remove 8 sticks.

To start, we need to find the largest number in the Fibonacci sequence that is less than or equal to 500. Looking at the sequence, we see that 21 is the largest number that fits this criteria. Therefore, on your first move, you can remove up to 21 sticks from the pile.

But should you remove all 21 sticks? Not necessarily. In Fibonacci nim, it is often advantageous to leave your opponent with a certain number of sticks that will force them to make a move that is disadvantageous. One such number is 4. If you can leave your opponent with 4 sticks, they will be forced to remove all 4 and you willbe left with a favorable position.

So, your first move should be to remove a number of sticks that is less than or equal to 21, but also leaves your opponent with 4 sticks or more. This will set you up for success in the game.

The probability that the weight of a randomly selected steer is between 1000 and 1520lbs is approximately 0.9192, or 91.92%.

Standard deviation = sqrt(variance) = sqrt(40,000) = 200

z = (x - μ) / σ

where z is the standardized value, x is the value of interest, μ is the mean, and σ is the standard deviation.

For x = 1000:

z1 = (1000 - 1100) / 200 = -0.5

For x = 1520:

z2 = (1520 - 1100) / 200 = 2.1

Using a calculator, we can use the normal cdf function with the z-scores to find the area between z1 and z2:

P(z1 < z < z2) = normal cdf(-0.5, 2.1) ≈ 0.9192

Rounding to four decimal places, we get:

P(1000 < x < 1520) ≈ 0.9192

Therefore, the probability that the weight of a randomly selected steer is between 1000 and 1520lbs is approximately 0.9192, or 91.92%.

The transitive theorem is a property of equality that states that if a = b and b = c, then a = c.

This theorem is often used in mathematics to prove equalities between different quantities. For example, if we know that x + y = z and z + a = b, we can use the transitive theorem to conclude that x + y + a = b.

The transitive theorem is based on the idea of transitive relations, which are relationships that hold between three elements in a given set, regardless of their specific values. Equality is a transitive relation because if a is equal to b, and b is equal to c, then a must also be equal to c.

The transitive theorem is an important concept in mathematics and is used in many different contexts, including algebra, geometry, and more. It is a useful tool for proving equalities and can help us solve problems and make deductions about different quantities.

Using linear equations, Coach Drummond should charge $432 per player and offer 153 scholarships to keep the price per player the same as this summer.

A linear equation is an algebraic equation that can be written in the form "ax + b = c", where "x" is the variable, "a" is the coefficient of the variable, "b" is a constant term, and "c" is another constant term. This form is called the standard form of a linear equation.

Now,

To solve this problem, we need to set up an equation that relates the total cost of running the camp to the number of players attending and the number of scholarships offered.

Let's let x be the number of scholarships offered and y be the price per player.

The total cost of running the camp is the fixed cost plus the variable cost per player, which is the cost for meals and snacks times the number of players attending. Using the given information, we can write:

Total cost = $15,700 + $525(450 - x)

On the revenue side, we have the total amount of money received from player fees and scholarships. The total number of players attending the camp is 450, including the 30 who received scholarships. So, the number of players who will pay the full price is 450 - x + 30. Multiplying this by the price per player, y, we get the total revenue:

Total revenue = y(450 - x + 30)

To keep the price per player the same as this summer, we set the total revenue equal to the total cost and solve for y:

y(450 - x + 30) = $15,700 + $525(450 - x)

Simplifying and solving for y, we get:

y = ($15,700 + $525(450 - x)) / (450 - x + 30)

Now we can analyze this equation to determine the number of players Coach Drummond will need to attend her camp next summer, the price per player, and the number of scholarships she should offer.

First, note that y is a rational function of x, which means that as x varies, y will also vary. In particular, y will increase as x decreases, which makes intuitive sense: if Coach Drummond offers more scholarships, she will need to charge a higher price per player to cover the fixed and variable costs.

To determine the number of players Coach Drummond will need to attend her camp next summer, we can set y equal to the price per player she charged this summer and solve for x:

y = $420 = ($15,700 + $525(450 - x)) / (450 - x + 30)

Multiplying both sides by 450 - x + 30 and simplifying, we get:

-105x + 16050 = 0

Solving for x, we get:

x = 153

This means that Coach Drummond should offer 153 scholarships next summer in order to keep the price per player the same as this summer.

To determine the price per player and the number of scholarships she should offer, we can plug x = 153 into the equation for y:

y = ($15,700 + $525(450 - 153)) / (450 - 153 + 30) = $432

So, Coach Drummond should charge $432 per player and offer 153 scholarships to keep the price per player the same as this summer.

To provide evidence to support this answer, we can check that the total revenue and total cost are equal at these values:

Total revenue = $432(450 - 153 + 30) = $202,896

Total cost = $15,700 + $525(450 - 153) = $202,896

Thus, Coach Drummond will break even if she charges $432 per player and offers 153 scholarships.
