One product/service that is currently in the decline stage is DVD rentals. The decline can be attributed to the rapid rise of digital streaming platforms and the decreasing popularity of physical media. Companies competing in a declining market have strategic options such as harvesting and divesting. Harvesting involves maximizing profits from the declining product/service by reducing costs and maintaining a loyal customer base, while divesting involves exiting the market and reallocating resources to more profitable ventures.

DVD rentals are in the decline stage of the product lifecycle due to several factors. The advent of digital streaming platforms like Netflix, Hulu, and Amazon Prime Video has revolutionized the way people consume media. The convenience and vast content libraries offered by these platforms have led to a significant decline in DVD rentals. Moreover, the proliferation of high-speed internet connections and the increasing availability of streaming devices have made it easier for consumers to access digital content.

In a declining market, companies have strategic options to consider. One option is harvesting, which involves maximizing profits from the declining product/service. Companies can achieve this by reducing costs associated with production, distribution, and marketing, as the demand for the product/service diminishes. They may also focus on retaining their loyal customer base by providing incentives, discounts, or exclusive offers. For example, DVD rental companies may lower rental fees, offer bundle deals, or introduce loyalty programs to retain their remaining customers.

Another strategic option is divesting, which involves exiting the declining market altogether. Companies may choose to reallocate their resources to more profitable ventures or invest in emerging technologies or industries. In the case of DVD rentals, companies could divest by shutting down physical rental stores and selling off their DVD inventory. They could then shift their focus to digital streaming services or invest in other areas with growth potential, such as content production or streaming device manufacturing.

The algebraic expression "3(7j + 2 - 4j)" can be translated to the verbal expression "Three times the sum of seven times a number, two, and the negation of four times the same number."

The algebraic expression "3(7j + 2 - 4j)" can be translated into a verbal expression as follows: "Take a number, multiply it by seven, add two to the result, subtract four times the same number, and finally multiply the entire expression by three."

To break it down further, let's consider the variable j as the unknown number. Multiplying 7 by j gives us seven times the unknown number, 7j. Adding 2 to this term gives us 7j + 2. Then, subtracting 4j from this sum represents subtracting four times the same unknown number. So, we have 7j + 2 - 4j.

Finally, multiplying the entire expression by 3 gives us 3(7j + 2 - 4j). This means that the entire calculation described above is repeated three times.

In summary, the verbal expression for 3(7j + 2 - 4j) can be stated as "Three times the sum of seven times a number, two, and the negation of four times the same number."

The missing measures are:

BCDE is a rhombus where ,

BC = 28 and BD = 32

BC is one of the sides of the rhombus, thus, all the sides (CD, DE, EB) will be 28 cm.

So, CD = 28cm

Now, BD = 32 which is the diagonal of the rhombus.

The diagonals bisect each other at a 90-degree angle.

Hence, FD = 1/2 x BD = 1/2x32 = 16 cm.

So, FD = 16 cm

To find EF, we can consider ΔEFD , which is right-angled at F, FD = 16cm and ED = 28cm  .

Thus, from Pythagoras theorem,

ED² = EF² + FD²

28² = EF² + 16²

EF = 22.97

EF = 23 cm

So, EF = 23 cm

EC would be two times EF( since diagonals bisect each other)

Therefore, EC = 2x23 = 46 cm

The angle between the vector (3 - √2)i + 3j and the positive x-axis can be determined using trigonometry.

To find the angle between the vector and the positive x-axis, we can use the arctan function. The angle can be calculated by taking the arctan of the y-component divided by the x-component of the vector.

In this case, the vector is given as (3 - √2)i + 3j. The x-component is 3 - √2, and the y-component is 3. Using the arctan function, we can calculate the angle as arctan(3 / (3 - √2)).

By substituting the values into a calculator or using trigonometric identities, we can find the angle. It is important to note that the arctan function returns an angle in radians. If we want the result in degrees, we can convert it by multiplying the result by 180/π.

\(y=(x−sinx)^2−sin2x\)if

\(n=0 y=(x+e2x+sin(x−1.5))^2\) if n>0Let's create a Python program to solve the given problem. In Python, we use the if...elif...else statement to execute different blocks of code based on different conditions. Here's the solution:Python Program

:x = int(input("Enter the value of x: "))

n = int(input("Enter the value of n: "))

if n < 0:y = x + cos(x) + 5 * tan(x)

elif n == 0:

y = (x - sin(x)) ** 2 - sin(2 * x)

else:y = \((x + e ** (2 * x) + sin(x - 1.5))\)

In the above Python program, we first read the values of the input parameters x and n using the input() function. Then we use the if...elif...else statement to execute different blocks of code based on the value of n. If n is less than 0, we calculate the value of y using the formula\(y′=x+cosx+5tan−1x\). If n is equal to 0, we calculate the value of y using the formula y\(=(x−sinx)^2−sin2x.\)

And, if n is greater than 0, we calculate the value of y using the formula\(y=(x+e2x+sin(x−1.5))^2\). Finally, we print the value of y using the print() function.I hope this helps.

Answer:

720°

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Divide by 60 to find number of sides (n)

n = 360° ÷ 60° = 6

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

The sum of the exterior angles of a regular polygon is 360º

Each exterior angle of a regular polygon is 60º/n

360º/n=60º

360/60=n

6=n

A polygon with 6 sides is a hexagon.

Use the formula (n-2)×180

(6-2)*180=4*180=720º

another solution...

you have 6 interior angles (hexagon)

if an exterior angle is 60º, the corresponding interior angle is 180-60=120º

you have 6 of these 120º angles

6*120=720º

Answer:

A = 82, B = 67 and C = 31

Step-by-step explanation:

Let the angles in the given  triangle be;

              A, B and C;

A is the largest angle and C is the smallest angle;

        B = 5 + 2C ------ i

        A = 3C - 11  ------ ii

A+ B + C = 180°  ----- iii

   Now, if we add equation i and ii;

            A + B = 5+2C + 3C - 11

            A+B = 5C - 6  ----- iv

Now insert equation iv into iii;

            5C -6 + C = 180

               6C = 180 + 6

               6C = 186

                   C = 31

A = 3C - 11 = 3(31) - 11 = 93 - 11  = 82

B = 5 + 2C = 5 + 2(31) = 67

A = 82, B = 67 and C = 31

After applying the ratio test to the given geometric series, the answer is option a: the series is convergent.

The given series is: 10 - 6 + 18/5 - 54/25 + ...

To determine whether this series is convergent or divergent, we can use the ratio test.

The ratio test states that a series of the form ∑aₙ is convergent if the limit of the absolute value of the ratio of successive terms is less than 1, and divergent if the limit is greater than 1. If the limit is equal to 1, then the ratio test is inconclusive.

So, let's apply the ratio test to our series:

|ax₊₁ / ax| = |(18/5) * (-25/54)| = 15/20.24 ≈ 0.74

As the limit of the absolute value of the ratio of successive terms is less than 1, we can conclude that the series is convergent.

Therefore, the answer is (a) convergent.

The  transformation of \(\(y= \frac{x^{4} }{6x+6}\)\) graph is compressed by a factor of 2.

The function is a rational function in which the numerator is a degree 4 polynomial, and the denominator is a degree 1 polynomial.

Rational functions are in the form of \(\(f(x) = \frac{p(x)}{q(x)}\)\), where p(x) and q(x) are polynomial functions and the degree of p(x) is less than the degree of q(x).

To transform a graph of a function, one can translate, stretch, or reflect it.

Here are some of the transformations of the function \(\(y= \frac{x^{4} }{6x+6}\)\)

Vertical Shift: To get the new graph, we add or subtract a constant from the function.

When f(x) is replaced with f(x) + k, we get a graph that is k units above the graph of f(x). In this case, if we subtract 2 from the equation, we get the following equation:

\(y = (x^4) / (6x+6) - 2\)

This means that the graph of the function is shifted 2 units downwards.

Horizontal Shift: To get the new graph, we add or subtract a constant to the variable.

When f(x+c) is replaced with f(x), the graph is shifted c units to the left.

When f(x-c) is replaced with f(x), the graph is shifted c units to the right.

In this case, we can shift the graph by substituting x-2 for x in the function.

The new function is: \(y = ((x-2)^4) / (6(x-2)+6)\)

This means that the graph is shifted 2 units to the right.

Vertical Stretch/Compression: When a constant is multiplied to the function, the graph is vertically stretched or compressed.

In this case, if the function is multiplied by 2, we get the following function:

\(y = 2(x^4) / (6x+6)\)

This means that the graph is compressed by a factor of 2.

It can also be stretched by dividing the function by a constant.

Horizontal Stretch/Compression:

When a constant is multiplied to the variable of the function, the graph is horizontally stretched or compressed. In this case, if the variable is divided by 2, we get the following function:

\(y = (x^4) / (3x+3)\)

This means that the graph is compressed by a factor of 2.

It can also be stretched by multiplying the variable by a constant.

Answer:

To prove that cosA/sinA -sinA/cosA=2cos^2A-1/sinA cosA, we can start by multiplying both sides of the equation by sinA cosA:

cosA/sinA -sinA/cosAsinA cosA = (2cos^2A-1)/sinA cosAsinA cosA

Now we can simplify the left side of the equation by using the identity sin^2A + cos^2A = 1:

cosAcosA -sinAsinA = (2cos^2A-1)cosAsinA

Now we can simplify the right side of the equation by using the identity cos^2A = 1 - sin^2A:

cosAcosA -sinAsinA = (2(1 - sin^2A)-1)cosAsinA

Finally, we can simplify the right side of the equation by using the identity sinAcosA = (sinAcosA)/(sinA*cosA):

cosAcosA -sinAsinA = (2(1 - sin^2A)-1)(sinAcosA)/(sinA*cosA)

Since both sides of the equation are equal, we can conclude that the statement is true.

To find the side lengths of a triangle using angles, you can employ trigonometric ratios like sine, cosine, and tangent

To find the side lengths of a triangle using angles, you can follow these steps:

Identify the given information: Determine which angles are known and which angles are unknown. Let's assume you have the measures of angles A, B, and C.

Apply the angle sum property: In a triangle, the sum of the interior angles is always 180 degrees. So, if you have the measures of two angles, you can find the measure of the third angle by subtracting the sum of the known angles from 180 degrees.

Determine the relationship between angles and side lengths: In a triangle, the lengths of the sides are related to the angles through the trigonometric ratios. The most common ratios are sine (sin), cosine (cos), and tangent (tan).

Use the trigonometric ratios: Depending on the given information, you can use the appropriate trigonometric ratio to find the side lengths. For example:

If you know an angle and the length of the side opposite to that angle, you can use the sine ratio: sin(A) = opposite/hypotenuse.

If you know an angle and the length of the adjacent side, you can use the cosine ratio: cos(A) = adjacent/hypotenuse.

If you know an angle and the lengths of the two sides that form that angle, you can use the tangent ratio: tan(A) = opposite/adjacent.

Solve for the unknown side lengths: Once you have the trigonometric equation involving an angle and side lengths, you can solve for the unknown side length using algebraic manipulations or a calculator.

Repeat these steps for the other angles to find the lengths of the remaining sides. Remember to consider the units of measurement (degrees or radians) and apply the appropriate trigonometric functions based on the given information.

The probability that a randomly selected group of 16 individuals from the campus will be selected is 0.8023 or 80.23%

Based on the sign in the elevator of the college library, the limit of 16 persons and weight limit of 2,500 pounds need to be adhered to. To ensure compliance with both limits, we need to consider both the number of people and their weight.

Assuming that the distribution of weights of individuals on campus is approximately normal with an average weight of 155 pounds and a standard deviation of 29 pounds, we can use this information to estimate the total weight of a group of 16 randomly selected individuals.

The total weight of a group of 16 individuals can be estimated as follows:

Total weight = 16 x average weight = 16 x 155 = 2480 pounds

To determine if this total weight is within the weight limit of 2,500 pounds, we need to consider the variability in the weights of the individuals. We can do this by calculating the standard deviation of the total weight using the following formula:

Standard deviation of total weight = square root of (n x variance)

where n is the sample size (16) and variance is the square of the standard deviation (29 squared).

Standard deviation of total weight = square root of (16 x 29^2) = 232.74

Using this standard deviation, we can calculate the probability that the total weight of the group of 16 individuals is less than or equal to the weight limit of 2,500 pounds:

Z-score = (2,500 - 2,480) / 232.74 = 0.86

Using a standard normal distribution table or calculator, we can find that the probability of a Z-score less than or equal to 0.86 is approximately 0.8023.

Therefore, the probability that a randomly selected group of 16 individuals from the campus will comply with both the number and weight limits in the elevator of the college library is approximately 0.8023 or 80.23%.
