The equation of the given circle in the standard form is given as x² + y² = 26.

In the question, we are given that the diameter of Circle \(Q\) terminates on the circumference of the circle at \((5,-1)\) and \((-5,1)\).

We are asked to write the equation of the circle in standard form.

The equation of the circle in standard form is given as (x - h)² + (y - k)² = r, where (h, k) is the center of the circle, and r is the radius of the circle.

The center of the circle can be found using the midpoint formula, as the center is the midpoint of the diameter.

Thus, the center is at ( (5 + (-5))/2, (-1 + 1)/2 ) = (0,0).

The length of the diameter can be calculated using the distance formula.

Thus, the length of the diameter of the circle is √((-5 - 5)² + (1 - (-1))²) = √( (-10)² + (2)² ) = √(100 + 4) = √104 = 2√26.

The radius is half the length of the diameter.

Thus, the radius, r = √26.

Now, we have the center (h, k) = (0,0), and the radius, r = √26.

Thus, the equation of the circle in the standard form, (x - h)² + (y - k)² = r ² can be shown as:

(x - 0)² + (y - 0)² = (√26)²,

or, x² + y² = 26.

Thus, the equation of the given circle in the standard form is given as x² + y² = 26.

Profitability index is 1.387. Thus, the correct option is (c) 1.387.

The formula for calculating the profitability index is:

P.I = PV of Future Cash Flows / Initial Investment

Where,

P.I is the profitability index

PV is the present value of future cash flows

The initial investment in the project is $30 million. The cash flow at the end of the first year is $2.85 million.

The present value of cash flows can be calculated using the formula:

PV = CF / (1 + r)ⁿ

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

n is the number of periods

For the first-year cash flow, n = 1, CF = $2.85 million, and r = 11%.

Substituting the values, we get:

PV = 2.85 / (1 + 0.11)¹ = $2.56 million

To calculate the present value of all future cash flows, we can use the formula:

PV = CF / (r - g)

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

g is the constant growth rate

For the subsequent years, CF = $2.85 million, r = 11%, and g = 3.85%.

Substituting the values, we get:

PV = 2.85 / (0.11 - 0.0385) = $39.90 million

The total present value of cash flows is the sum of the present value of the first-year cash flow and the present value of all future cash flows.

PV of future cash flows = $39.90 million + $2.56 million = $42.46 million

Profitability index (P.I) = PV of future cash flows / Initial investment

= 42.46 / 30

= 1.387

Therefore, the correct option is (c) 1.387.

Answer:

The smallest number for n is 8.

Step-by-step explanation:

It is 8 because 40 is a factor of 8.

Is that enough information for you.

The Cauchy-Riemann equations are satisfied, the function is analytic and differentiable. sin z is analytic everywhere.

It is found that u = sin x cosh y and v = cos x sinh y. To show that sin z is analytic everywhere by checking u and v found in problem 4 satisfy the Cauchy-Riemann equations.

Therefore, we need to find the partial derivatives of u and v, which are defined by:

∂u/∂x = cos x cosh y

∂u/∂y = sin x sinh y

∂v/∂x = - sin x sinh y

∂v/∂y = cos x cosh y

For sin z to be analytic everywhere, we must satisfy the Cauchy-Riemann equations.

∂u/∂x = ∂v/∂y

∂u/∂y = -∂v/∂x

∂u/∂x = cos x cosh y

∂v/∂y = cos x cosh y

∂u/∂y = sin x sinh y

∂v/∂x = - sin x sinh y

Now, we have

∂u/∂x = ∂v/∂y and ∂u/∂y = -∂v/∂x and they satisfy the Cauchy-Riemann equations. Therefore, sin z is analytic everywhere.

As the Cauchy-Riemann equations are satisfied, the function is analytic and differentiable. Thus, it can be concluded that sin z is analytic everywhere by verifying the Cauchy-Riemann equations.

Answer:

The half-life of carbon-14 is 5,730 years. This means that every 5,730 years, half of the carbon-14 in a sample will decay. So, if a sample contains 32% of its original amount of carbon-14, it is about 2 * 5,730 = 11,460 years old.

However, it is essential to note that radiocarbon dating is not an exact science. There is a margin of error of about 20 years. So, the skull's actual age could be between 11,260 and 11,660 years old.

Here is a formula that can be used to calculate the age of a sample using radiocarbon dating:

```

Age = (5,730 * ln(A/Ao)) / ln(2)

```

Where:

* Age is the age of the sample in years

* A is the amount of carbon-14 in the sample

* Ao is the original amount of carbon-14 in the sample

* ln is the natural logarithm function

In this case, A = 0.32 and Ao = 1.0. So, the age of the skull is:

```

Age = (5,730 * ln(0.32) / ln(2)) = 11,460 years

```

Step-by-step explanation:

Answer:

4535 years.

Step-by-step explanation:

The formula used to calculate the age of a sample by carbon-14 dating is3:

t=−0.693ln(N0​Nf​​)​×t1/2​

where:

t is the age of the sample

Nf is the number of carbon-14 atoms in the sample after time t

N0 is the number of carbon-14 atoms in the original sample

t1/2 is the half-life of carbon-14 (5730 years)

In your case, the skull contains 32% of its original amount of carbon-14, which means that Nf/N0 = 0.32. You can plug in this value and the half-life into the formula and get:

t=−0.693ln(10.32​)​×5730

Using a calculator, you can simplify this expression and get:

t=−1.139×−0.693×5730

t=4534.7

A. Mix C, with 4 cups of concentrate and 8 cups of cold water, will make the most "lemony" juice. This is because it has the highest ratio of concentrate to water among the given recipes.

B. Mix B, with 1 cup of concentrate and 4 cups of cold water, will make the least "lemony" juice. This is because it has the lowest ratio of concentrate to water among the given recipes. With less concentrate, the flavor of the juice will be milder and less pronounced.

C. To make juice for 240 campers, each camper receiving ½ a cup of juice, we can calculate the total amount of juice needed. Since there are 240 campers and each camper gets ½ a cup, the total amount of juice required is 240 * 0.5 = 120 cups.

For Mix A, the ratio of concentrate to water is 2:3. To find the amount of concentrate needed, we can set up the equation 2x + 3x = 120, where x represents the number of cups of concentrate needed. Solving the equation, we get 5x = 120, which gives x = 24. Therefore, we need 24 cups of concentrate and 36 cups of water for Mix A. Similarly, for Mix B, the ratio of concentrate to water is 1:4. Setting up the equation x + 4x = 120, we find that x = 20. Hence, we need 20 cups of concentrate and 80 cups of water for Mix B. For Mix C, the ratio of concentrate to water is 4:8, which simplifies to 1:2. Therefore, we need 120 cups of concentrate and 240 cups of water for Mix C. For Mix D, the ratio of concentrate to water is 3:5. Setting up the equation 3x + 5x = 120, we find that x = 12. Thus, we need 36 cups of concentrate and 60 cups of water for Mix D. Lastly, for Mix E, the ratio of concentrate to water is 3:4. Setting up the equation 3x + 4x = 120, we find that x = 15. Hence, we need 45 cups of concentrate and 60 cups of water for Mix E.

Step-by-step explanation:

Zone(area) = L x W = 2.5 x 2.5 = 6.25 square meters. 

Of all rectangles with an edge of 10 meters, the one that has the greatest zone(area) could be a square.

To see why, let's assume that a rectangle with a border of 10 meters has measurements of length L and width W.

At that point, we know that:

2L + 2W = 10

Rearranging this condition, we get:

L + W = 5

Presently, we need to discover the most extreme range encased by the rectangle, which is given by:

Area = L x W

Able to illuminate for one variable in terms of the other utilizing the condition L + W = 5:

L = 5 - W

Substituting this expression for L into the condition for the zone, we get:

Zone = (5 - W) x W

Extending and disentangling this expression, we get:

Area = 5W - W²

To discover the most extreme esteem of this quadratic expression, we will take its subsidiary with regard to W and set it to break even with zero:

dArea/dW = 5 - 2W =

Tackling for W, we get:

W = 2.5

Substituting this esteem back into the condition for the edge, we get:

L = 2.5

Hence, the measurements of the rectangle that has the greatest region are L = 2.5 meters and W = 2.5 meters, which implies it could be a square. The most extreme zone enclosed by the rectangle is:

Zone(area) = L x W = 2.5 x 2.5 = 6.25 square meters.

The area of the unshaded region is found to be 58.5 square units.

The circle is a rounded figure with no sides or edges.

A circle is defined in geometry as an enclosed, 2-dimensional curved object.

The diagram in the question depicts a triangle encircled by a circle with radius r. The triangle is entirely darkened.

As a result, the size of the unshaded region will be the difference between the areas of the circle and the triangle.

The area of the unshaded region equals the area of the circle minus the area of the triangle.

The formula for calculating the area of circle;

\(A=\pi r^{2}\)

Where A denotes its area and r denotes the radius.

The formula for calculating the area of a triangle.

\(A=\frac{1}{2} b h\)

Where A denotes the area, b the base, and h the perpendicular.

∴ The region of a unshaded region  \(=\pi r^{2}-\frac{1}{2} b h\)

Substituting the values;

h = 4, b = 10, and r = 5

The region of a unshaded region = \(\pi \times 5^{2}-\frac{1}{2} \times 10 \times 4\)

                                                       =  25π - 5×4

Put  π = 3.14

The area of a unshaded region = 25×3.14 - 5×4

No, the boy did not use the same amount of power the second time.

Power is defined as the rate at which work is done, and it is calculated as the amount of work done divided by the time taken.

In this scenario, the work done is the same because the boy mows the same distance (assuming the lawn remained the same size). However, the time taken to complete the task is different.

First time: Time = 1.0 hour

Second time: Time = 0.5 hour

Since power is directly proportional to work and inversely proportional to time, we can conclude that the power output was higher the second time. This is because the same amount of work was accomplished in half the time. The boy was able to mow the lawn more quickly, indicating a greater power output during the second attempt.
