While there are basically no variable costs to the website version, the print edition does cost $16 per month to print and deliver to households.If marketing research indicates that an average print only subscriber will only continue their subscription for 24 months if they don't also purchase the digital edition, what is the 3 year CLV of a current print edition customer taking into consideration those that will choose print only (24 month) and those that choose to add the digital edition (who then drop the print after 16 months)?

The term you are looking for is the proportion of the total variation in the dependent variable explained by the regression model (or independent variable), which is known as the A) coefficient of determination.

The coefficient of determination, also known as R-squared, is a statistical measure that indicates the proportion of the total variation in the dependent variable that is explained by the regression model or independent variable. It ranges from 0 to 1, with higher values indicating a better fit of the model to the data. The other terms mentioned - variable, proportion, and independent - are all related to the concept of regression analysis, which is used to identify the relationship between a dependent variable and one or more independent variables, and to quantify the extent to which changes in the independent variables affect the dependent variable.

Using the sum rule, we can add the derivatives of each term to find the derivative of the function:

dy/dx (y) = dy/dx (2x^5) + dy/dx (-4x^3) + dy/dx ((9/4)x^3)
dy/dx (y) = 10x^4 - 12x^2 + (27/4)x^2

Hi! To find the level of marketing expenditure that will maximize sales and the maximum sales value, we can follow these steps:

1. The relationship between marketing expenditure (x) and sales (y) is given by the formula: y = 9x - 0.20x^2 + 8.
2. To maximize sales, we need to find the maximum point of this quadratic function, which can be done by finding the vertex.
3. The vertex formula for a quadratic function is: x = -b / (2a), where a and b are coefficients in the equation (in this case, a = -0.20 and b = 9).
4. Calculate x (marketing expenditure) for the vertex: x = -9 / (2 * -0.20) = -9 / -0.40 = 22.50.
5. Round the marketing expenditure to 2 decimal places: 22.50.
6. Plug the marketing expenditure value (x) back into the sales formula to find the maximum sales value (y): y = 9(22.50) - 0.20(22.50)^2 + 8.
7. Calculate y: y = 202.50 - 0.20(506.25) + 8 = 202.50 - 101.25 + 8 = 109.25.
8. Round the maximum sales value to 2 decimal places: 109.25.

So, the level of marketing expenditure that will maximize sales is $22.50, and the maximum sales value is $109.25.

The given integral is:

[tex]∫[0,6] 1/x dx[/tex]

We know that the integral of 1/x is ln(x), and the antiderivative of ln(x) is xln(x) - x.

So, applying the limits of integration, we get:

[tex]∫[0,6] 1/x dx = ln(x)|[0,6] = ln(6) - ln(0)[/tex]

The natural logarithm of zero is unclear, so the indispensably isn't characterized at x = 0. In this manner, the indispensability is unique.

An integral is said to be divergent in the event that it does not have limited esteem. In other words, on the off chance that the fundamentally does not meet a genuine number, it is said to be unique.

There are a few reasons why a fundamentally may be unique. A few common reasons incorporate:

The integrand gets to be unbounded at a few points inside the limits of integration.

The integrand does not approach zero as the constraint of integration approaches boundlessness.

The limits of integration are interminable, and the integrand does not merge to a limited esteem as the limits approach interminability.

When an indispensably is disparate, it implies that the zone beneath the bend is interminable or does not exist.

To calculate the moment of inertia of an object, you need to know its mass and the distance it is from the axis of rotation. In this case, the object has a mass of 12 kg and is distributed 4 meters from the axis of rotation. The formula to calculate the moment of inertia is I = mr^2, where the moment of inertia, m is the mass, and r is the distance from the axis of rotation.

Using this formula, we can calculate the moment of inertia of the object:

I = 12 kg x (4 m)^2

I = 192 kgm^2

Therefore, the moment of inertia of the object is 192 kgm^2.
To calculate the moment of inertia for an object, you can use the following formula:

Moment of Inertia (I) = Mass (m) × Distance² (r²)

Given the object's mass is 12 kg and the mass is distributed 4 meters from the axis of rotation, we can plug these values into the formula:

I = 12 kg × (4 m)²

Now, we'll square the distance:

I = 12 kg × 16 m²

Finally, multiply the mass and the squared distance:

I = 192 kg·m²

So, the moment of inertia of the object is 192 kg·m².

Step-by-step explanation: Brainliest pls:)

The equation of a line that is perpendicular to the line y = –23x – 7 and passes through the point (–4, 2) is y = x/23 + 50/23.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

Since the equation of this line is perpendicular to the line y = –23x – 7, the slope is given by;

Slope, m = -23

m₁ × m₂ = -1

-23 × m₂ = -1

m₂ = -1/-23

Slope, m₂ = 1/23

At data point (-4, 2) and a slope of 1/23, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 2 = 1/23(x - (-4))  

y - 2 = 1/23(x + 4)

y = x/23 + 4/23 + 2

If you invest $2,000 for 3 years at an interest rate of 6%, compounded every 6 months. The value of your investment at the end of the period is $2,397.39.

The interest rate is 6% and it is compounded every 6 months, so the period is 6 months. To calculate the value of the investment at the end of the period, we need to use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:
A = the final amount.
P = the principal amount (initial investment)
r = the annual interest rate (6%).
n = the number of times the interest is compounded per year (2, since it's compounded every 6 months).
t = the time period in years (3)

Plugging in the numbers, we get:

A = 2,000(1 + 0.06/2)^(2*3)

To model the population of a city, we can use the formula:

f(x) = 1,596,000 * (1 + 0.035)^x

Where x is the number of years since 2020 and 0.035 represents the annual increase rate of 3.5%.

To model the population of a city, we need to take into account the initial population in 2020 and the annual increase rate of 3.5%. The annual increase rate of 3.5% means that the population is expected to grow by 3.5% every year from the previous year's population. To incorporate this growth rate into our model, we can use the formula for compound interest:

A = P * (1 + r)^t

Where A is the final amount, P is the initial amount, r is the annual interest rate, and t is the number of years. In our case, the final amount is the population after x years since 2020, the initial amount is the population in 2020 (1,596,000), the annual interest rate is 3.5%, and the number of years is x.

By substituting the values into the formula, we get:

f(x) = 1,596,000 * (1 + 0.035)^x

This formula can be used to calculate the expected population of the city for any year in the future. For example, if we want to know the population in 2025, we can substitute x = 5 into the formula:

f(5) = 1,596,000 * (1 + 0.035)^5

= 1,825,854

Therefore, we can expect the population of the city to be around 1,825,854 in 2025, assuming the same annual increase rate of 3.5%.

a rhombus is a parallelogram with a pair of opposite equal acute angles, a pair of opposite equal obtuse angles, and four equal sides.

in other words, it is a parallelogram with 4 equal sides, including a square as a special case.

the diagonal intersection point is the midpoint of both diagonals.

the diagonals intersect each other at a right angle (90°).

and they split each vertex angle in half.

so, they split the whole rhombus into 4 equal right-angled triangles.

and remember, the sum of all angles in a triangle is always 180°.

an "obtuse" angle means an angle larger than 90°.

an "acute" angle means an angle smaller than 90°.

because of all that, in the triangle PKE the angle K must be greater than 45° (90/2 = 45), so that the rhombus angle K can be "obtuse", as it must be twice the triangle angle K.

the triangle angle E is 90°.

so, the 16° must be triangle angle P.

and the triangle angle K is then

triangle angle K = 180 - 90 - 16 = 74°.

so, rhombus angle K = rhombus angle N = 2×74 = 148°

Let's find the Fourier transform of the given function f(t) = sin 3t, k≤|t|≤2k and 0, |t|>2k.

For k≤|t|≤2k, we can write:

f(t) = sin 3t

= (1/2i) (e^(i3t) - e^(-i3t))

Using the Fourier transform properties, we can write:

F(w) = (1/2i) [∫[from -2k to -k] e^(i3t) e^(-iwt) dt + ∫[from k to 2k] e^(i3t) e^(-iwt) dt]

Applying the integral formula ∫ e^(ax) dx = (1/a) e^(ax) + C, we get:

F(w) = (1/2i) [(1/i(3-w))(e^(i(3-w)2k) - e^(i(3-w)k)) + (1/i(3+w))(e^(i(3+w)k) - e^(i(3+w)2k))]

Simplifying the above expression, we get:

F(w) = (1/2) [(sin(2kw-3) - sin(kw-3))/(kw-3) + (sin(kw+3) - sin(2kw+3))/(kw+3)]

For |t|>2k, f(t) = 0. Thus, its Fourier transform is also 0.
