\((x - 4)^2 + y^2 = 4\) is the equation of the given circle.

As we can see in the graph that the radius of the circle is 2 units and the circle is passing through the point (4, 0).

To find the equation of a circle, we need the center coordinates (h, k) and the radius (r). In this case, the radius is given as 2 units, and the circle passes through the point (4, 0).

The center of the circle can be found by taking the coordinates of the given point. In this case, the x-coordinate of the point (4, 0) represents the horizontal position of the center.

Center coordinates: (h, k) = (4, 0)

Now, we can write the equation of the circle using the formula:

\((x - h)^2 + (y - k)^2 = r^2\)

Substituting the values into the equation, we get:

\((x - 4)^2 + (y - 0)^2 = 2^2\)

Simplifying further, we have:

\((x - 4)^2 + y^2 = 4\)

Therefore, the equation of the circle with a radius of 2 units, passing through the point (4, 0), is \((x - 4)^2 + y^2 = 4\).

The correct option is AV > 0. This indicates that work is being done on the system and the system's kinetic energy is increasing.

The work done on the system is always positive when the applied force and the displacement of the system are in the same direction (AV > 0).

To understand this, let's consider the definition of work. Work is given by the dot product of the force vector (F) applied to the system and the displacement vector (d) of the system:

Work = F · d

The dot product of two vectors is positive when the angle between them is less than 90 degrees, indicating that they are in the same direction. When the force and displacement are in the same direction, the work done on the system is positive.

If the force and displacement are in opposite directions, the dot product will be negative, and the work done on the system will be negative (AV < 0). This would imply that work is being done by the system rather than on the system.

In the case where the applied force is zero (AV = 0), no work is done on the system as there is no force acting to cause a displacement.

The change in mechanical energy (AE) of the system being greater than zero (AE > 0) does not guarantee that the work done on the system is always positive. AE > 0 indicates that the system's mechanical energy has increased, but it doesn't provide information about the work done specifically. Therefore, the correct option is AV > 0.

Answer:

115 degrees

Step-by-step explanation:

The third angle will measure 115° so option (A) will be correct.

The three-sided shape known as a triangle is sometimes used to allude to it. Every triangle has three sides and three angles, some of which might be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

Sum of all three internal angles of the triangle = 180°

Sum of two angles + third angle = 180°

Given that,

Two angles of a triangle add up to 65° so

65° + third angle = 180°

Third angle = 180 - 65°

Third angle = 112°

Hence the third angle will be 112° measure.

Step-by-step explanation:

So wiggly, remember that slope is change in y/change in x, or in simpler terms, y/x. Thinking of this, y/x must simplyfy to -3. Or, you can think of it as -3/1.

So know that we have rewrote this as a slope of -3/1, lets use it. Where do we start? Well, we must start at point A, which is at 2 x and 7 y.

Now, going to the  RIGHT(+1x) and going DOWN(-3y) we will go from 2x and 7y to 3x and 4y.

Are we on a point yet? Nope, lets do this again.

Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 13x and 4y to 4x and 1y.

Are we on a point yet? Still no, lets try this one more time.

Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 4x and 1y to 5x and -2y.

Are we on a point? YUP. We cna see that point B is at 5x and -2y.

A consumer's optimal consumption bundle represents the best possible combination of goods and services that a consumer can purchase given their budget constraint and the prices of those goods. In this scenario, the utility function given is a(f, g) = 2√f + g

The price of good f is 2 and the price of good g is 1.

The consumer's income is 3/4 and 1/4 respectively. Using these, we can solve for the optimal consumption bundle for the consumer using the utility function.

a) To calculate the optimal consumption bundle when the income is 3/4, we can use the following method:

Let the optimal consumption bundle be represented as (x, y).

Here, x represents the quantity of good f consumed, and y represents the quantity of good g consumed.

The consumer's budget constraint can be given as follows:

2x + y = 3/4

The consumer's goal is to maximize their utility, which can be represented as:

a(f, g) = 2√f + g = 2√x + y

The consumer's optimization problem can be represented as follows:

Maximize 2√x + y subject to 2x + y = 3/4

To solve this optimization problem, we can use the Lagrangian function:

L(x, y, λ) = 2√x + y - λ(2x + y - 3/4)

To find the optimal consumption bundle, we must solve for the following set of equations:

∂L/∂x = 0,

∂L/∂y = 0, and

∂L/∂λ = 0

Solving for the first two equations yields the following:

x/√x = λ2y - λ

= 1

The third equation can be used to solve for λ:

2x + y - 3/4 = 0

Solving for x and y using the first two equations and the value of λ yields:

x = 1/2 and y = 1/4

Therefore, the optimal consumption bundle is (1/2, 1/4)

b) To calculate the optimal consumption bundle when the income is 1/4, we can use a similar method to the one used in part a.

Using the same budget constraint of 2x + y = 1/4 and the same utility function of 2√x + y, we can solve for the optimal consumption bundle by using the Lagrangian function L(x, y, λ) = 2√x + y - λ(2x + y - 1/4).

Solving for the same set of equations, we get:

x = 1/8 and y = 0

Therefore, the optimal consumption bundle is (1/8, 0)

Utility functions are mathematical representations of the satisfaction a consumer derives from consuming goods and services. A consumer's optimal consumption bundle represents the best possible combination of goods and services that a consumer can purchase given their budget constraint and the prices of those goods.In this question, we were given a specific utility function and the prices of two goods. We used this information to solve for the optimal consumption bundle when the consumer's income was 3/4 and 1/4 respectively.To solve for the optimal consumption bundle, we used the Lagrangian method to optimize the consumer's utility function subject to their budget constraint. The Lagrangian method involves creating a Lagrangian function that includes the consumer's utility function and their budget constraint. We then solve for the first-order conditions of the Lagrangian function, which are a set of equations that yield the optimal values of the goods consumed.This method is useful for solving for optimal consumption bundles because it takes into account both the consumer's preferences and their budget constraint. By solving for the optimal consumption bundle, we can determine how much of each good the consumer should consume to maximize their satisfaction given their budget constraint

Utility functions and optimal consumption bundles are important concepts in microeconomics. They allow us to understand how consumers make choices and how they allocate their resources. By solving for the optimal consumption bundle, we can determine the best combination of goods and services that a consumer can purchase given their budget constraint and the prices of those goods.

The given subset satisfies all three conditions of a subspace, we can conclude that it is a subspace of ℙ2.

To prove this, we need to show that the set satisfies the three conditions of a subspace: closure under addition, closure under scalar multiplication, and contains the zero vector.

Let p(t) and q(t) be two polynomials of the form \(p(t) = at²\)and \(q(t) = bt²\), where a and b are real numbers. Then, the sum of these two polynomials is:

\(p(t) + q(t) = at² + bt²\)

\(= (a+b)t²\)

Since a+b is a real number, the sum of p(t) and q(t) is still of the form at² and thus belongs to the given set. Therefore, the set is closed under addition.

Now, let p(t) be a polynomial of the form \(p(t) = at²\) and c be a real number. Then, the scalar multiple of p(t) by c is:

\(c p(t) = c(at²) = (ca)t²\)

Since ca is a real number, the scalar multiple of p(t) by c is still of the form at² and thus belongs to the given set. Therefore, the set is closed under scalar multiplication.

Finally, the zero vector is the polynomial of the form \(p(t) = 0t² = 0\), which clearly belongs to the given set. Therefore, the set contains the zero vector.

The number of arrangements of 6 balls with 2 red balls and 2 blue balls, we need to consider the number of ways to choose 2 red balls from the 4 available red balls and the number of ways to choose 2 blue balls from the 4 available blue balls.

These are both combinations, and we can use the formula for combinations to calculate them:

C(n, k) = n! / (k! (n-k)!).

For the red balls, C(4, 2) = 4! / (2! (4-2)!) = 6.

For the blue balls, C(4, 2) = 4! / (2! (4-2)!) = 6.

The total number of arrangements of 6 balls with 2 red balls and 2 blue balls is the product of the number of arrangements for each type of ball:

Therefore, P(x) = R(x) - C(x)800 = 9x - (2.5x + 60)800 = 9x - 2.5x - 60900 = 6.5x = 900 / 6.5x ≈ 138

So, she needs to produce and sell approximately 138 T-shirts to make a profit of $800.

Given Data Joanne sells silk-screened T-shirts at community festivals and craft fairs. Her marginal cost to produce one T-shirt is $2.50.

Her total cost to produce 60 T-shirts is $210, and she sells them for $9 each.
Linear Cost Function

The linear cost function is a function of the form:

C(x) = mx + b, where C(x) is the total cost to produce x items, m is the marginal cost per unit, and b is the fixed cost. Therefore, we have:

marginal cost per unit = $2.50fixed cost, b = ?

total cost to produce 60 T-shirts = $210total revenue obtained by selling a T-shirt = $9

a) To find the value of the fixed cost, we use the given data;

C(x) = mx + b

Total cost to produce 60 T-shirts is given as $210

marginal cost per unit = $2.5

Let b be the fixed cost.

C(60) = 2.5(60) + b$210 = $150 + b$b = $60

Therefore, the linear cost function is:

C(x) = 2.5x + 60b) We can use the break-even point formula to determine the quantity of T-shirts that must be produced and sold to break even.

Break-even point:

Total Revenue = Total Cost

C(x) = mx + b = Total Cost = Total Revenue = R(x)

Let x be the number of T-shirts produced and sold.

Cost to produce x T-shirts = C(x) = 2.5x + 60

Revenue obtained by selling x T-shirts = R(x) = 9x

For break-even, C(x) = R(x)2.5x + 60 = 9x2.5x - 9x = -60-6.5x = -60x = 60/6.5x = 9.23

So, she needs to produce and sell approximately 9 T-shirts to break even. Since the number of T-shirts sold has to be a whole number, she should sell 10 T-shirts to break even.

c) The profit function is given by:

P(x) = R(x) - C(x)Where P(x) is the profit function, R(x) is the revenue function, and C(x) is the cost function.

For a profit of $800,P(x) = 800R(x) = 9x (as given)C(x) = 2.5x + 60

Therefore, P(x) = R(x) - C(x)800

= 9x - (2.5x + 60)800

= 9x - 2.5x - 60900

= 6.5x = 900 / 6.5x ≈ 138

So, she needs to produce and sell approximately 138 T-shirts to make a profit of $800.

The obtained limit is identical to the limit that was specified. Therefore, the right answer is option C.

Generally, the equation for the limit  is  mathematically given as

\($\lim _{n \rightarrow \infty} \sum_{i=1}^{n} \frac{4}{n} \sqrt{1+\frac{4 i}{n}}$.\)

The goal is to locate the zone whose area corresponds to the value supplied by the limit.

The definite integral of a function is what is used to compute the area of that function that is underneath its graph.

The limit,

\(\lim _{n \rightarrow \infty} \sum_{i=1}^{n} f(a+i \cdot \Delta x) \Delta x\)

where\($\Delta x=\frac{b-a}{n}$\) and \($x_{i}=a+i \Delta x$\) for the interval $[a, b]$, is equivalent to the integral

\(\int_{a}^{b} f(x) d x .\)

The given limit can also be written as

\(\lim _{n \rightarrow \infty} \sum_{i=1}^{n} \sqrt{1+\left(\frac{4}{n}\right)} i \cdot \frac{4}{n} .\)

In this limit, \($\Delta x=\frac{4}{n}$\). It can be observed that\($f(a+i \Delta x)=\sqrt{1+\left(\frac{4}{n}\right)} i$\) which implies that \($a=1$ and $f(x)=\sqrt{x}$.\)

Solve the \($\Delta x=\frac{b-a}{n}$\)equation for as follows:

\(\begin{aligned}\frac{4}{n} &=\frac{b-1}{n} \\4 &=b-1 \\5 &=b\end{aligned}\)

Therefore, the specified limit may be expressed as an integral as follows:

\(\lim _{n \rightarrow \infty} \sum_{i=1}^{n} \sqrt{1+\left(\frac{4}{n}\right) i} \cdot \frac{4}{n}=\int_{1}^{5} \sqrt{x} d x\)

Therefore, the limit that has been provided designates the area of the graph of "sqrt(x)" on the interval.[1,5]

However, none of the available choices are compatible with this choice. So, consider

\(a=0, f(x)=\sqrt{1+x}$ and $\Delta x=\frac{4}{n}$.\)

Find the value of $b$ as:

\($$\begin{aligned}\frac{4}{n} &=\frac{b-0}{n} \\4 &=b\end{aligned}$$\)

Find the value of x_{i} as:

\(\begin{aligned}&x_{i}=0+\frac{4}{n} i \\&x_{i}=\frac{4}{n} i\end{aligned}\)

$$

Thus, the integral \($\int_{0}^{4} \sqrt{1+x} d x$\) can be expressed using the equation \($\int_{a}^{b} f(x) d x=\lim _{n \rightarrow \infty} \sum_{i=1}^{n} f\left(x_{i}\right) \Delta x$\)

\(\begin{aligned}\int_{0}^{4} \sqrt{1+x} d x &=\lim _{n \rightarrow \infty} \sum_{i=1}^{n} \sqrt{1+\frac{4 i}{n} \frac{4}{n}} \\&=\lim _{n \rightarrow \infty} \sum_{i=1}^{n} \frac{4}{n} \sqrt{1+\frac{4 i}{n}}\end{aligned}\)
