The given equation `mx cx kx=f(t)` is a second-order linear differential equation with constant coefficients. The general solution to this type of equation is given by the sum of the complementary solution `x_c(t)` and the particular solution `x_p(t)`.

The complementary solution x_c(t) is the solution to the associated homogeneous equation mx cx kx=0. The characteristic equation for this homogeneous equation is mr^2 + cr + k = 0. Solving this quadratic equation gives two roots r_1 and r_2. The complementary solution can then be written as x_c(t) = C_1e^(r_1t) + C_2e^(r_2t).

The particular solution x_p(t) depends on the form of the function f(t). There are several methods for finding the particular solution, such as undetermined coefficients or variation of parameters.

Once the complementary and particular solutions are found, the general solution to the given differential equation is given by x(t) = x_c(t) + x_p(t). The constants C_1 and C_2 can then be determined using the initial conditions x(0)=0 and x'(0)=0.

Without more information about the function f(t), it is not possible to find a more specific solution to the given differential equation.

The length of the longest side of the parallelogram is 14.7 cm.

We have,

Let's denote the length of the long sides of the parallelogram as L.

In a parallelogram, the opposite sides are congruent, so both long sides have the same length.

The Law of Cosines states:

c² = a² + b² - 2ab cos(C)

Where:

c is the length of the side opposite the angle C,

a and b are the lengths of the other two sides,

C is the measure of the angle opposite side c.

The short sides of the parallelogram are 12.0 cm, and the acute angle is 65°.

Applying the Law of Cosines to find the length of the long side:

[tex]L^2 = 12^2 + 12^2 - 2 * 12 * 12 * cos(65)\\L^2 = 144 + 144 - 288 * cos(65)\\L^2 = 288 - 288 * cos(65)\\L = \sqrt{(288 - 288 * cos(65))}\\L = 14.7 cm[/tex]

(rounded to the nearest tenth of a centimeter)

Thus,

The length of the longest side of the parallelogram is 14.7 cm.

Step-by-step explanation:

There are 25,200 different ways in which 6 adults and 3 children can stand together in a line such that no two children are next to each other.

To determine the number of ways in which 6 adults and 3 children can stand together in a line such that no two children are next to each other, we can use the concept of permutations.

Let's consider the adults and children as distinct entities. First, we will calculate the number of ways to arrange the adults in a line, and then we will insert the children into the gaps between the adults.

Step 1: Arrange the adults

Since there are 6 adults, there are 6! (6 factorial) ways to arrange them in a line.

Step 2: Insert the children

Now, we have 7 possible positions between the adults where the children can be inserted. These positions include the spaces before the first adult, between each pair of adjacent adults, and after the last adult.

To ensure that no two children are next to each other, we need to choose 3 distinct positions out of the 7 available positions. This can be done in 7C3 ways, which represents the combination of 7 positions taken 3 at a time.

Using the formula for combinations, 7C3 can be calculated as follows:

7C3 = 7! / (3! * (7-3)!)

= 7! / (3! * 4!)

= (7 * 6 * 5) / (3 * 2 * 1)

= 35

Step 3: Multiply the results

Finally, we multiply the number of ways to arrange the adults (6!) by the number of ways to insert the children (35) to obtain the total number of arrangements:

Total number of arrangements = 6! * 35

= 720 * 35

= 25,200

Therefore, there are 25,200 different ways in which 6 adults and 3 children can stand together in a line such that no two children are next to each other.

(x + 7) is a factor of f(x) = x^3 - 3x^2 + 2x - 8. By using synthetic division, we find that the remainder is 0.

To determine if (x + 7) is a factor of the polynomial f(x) = x^3 - 3x^2 + 2x - 8, we can use synthetic division.

Performing synthetic division with the divisor (x + 7), we set up the division as follows:

  -7 |   1   -3   2   -8

      |_________________

        1  -10  72   -520

The numbers in the bottom row of the synthetic division represent the coefficients of the quotient polynomial. In this case, the quotient polynomial is 1x^2 - 10x + 72, and the remainder is -520.

Since the remainder is not zero, (x + 7) is not a factor of f(x). If (x + 7) were a factor, the remainder would be zero.

Therefore, (x + 7) is not a factor of f(x) = x^3 - 3x^2 + 2x - 8.

Answer:

The 99% confidence interval for the mean length of the songs on Marcelina's phone is approximately (3.08 minutes, 3.78 minutes).

Step-by-step explanation:

To calculate the 99% confidence interval for the mean length of the songs on Marcelina's phone, we can use the formula:

Confidence Interval = Sample Mean ± (Z * Standard Error)

Where:

Sample Mean is the mean length of the sample songs (3.43 minutes).

Z is the critical value associated with the desired confidence level (99% confidence level corresponds to a Z-value of approximately 2.576).

Standard Error is the standard deviation of the sample divided by the square root of the sample size.

Given that the sample size is 28 songs and the standard deviation is 0.72 minutes, we can calculate the standard error as:

Standard Error = Standard Deviation / √(Sample Size)

Standard Error = 0.72 / √28 ≈ 0.136

Now we can substitute the values into the formula:

Confidence Interval = 3.43 ± (2.576 * 0.136)

Calculating the confidence interval:

Confidence Interval = 3.43 ± 0.350

Confidence Interval = (3.08, 3.78)

Therefore, based on this sample, the 99% confidence interval for the mean length of the songs on Marcelina's phone is approximately (3.08 minutes, 3.78 minutes).

The probability that exactly 10 patients are referred to an oncologist in a month is 0.036

The probability that between five and 15 inclusive are referred to an oncologist in a month is 0.98.

The probability that more than 10 patients are referred to an oncologist in a month is 0.873

Given:

A researcher used Poisson distribution to model the number of patients per month referred to an oncologist. The researcher uses a rate of 16 patients per month. We have to find the probabilities for different conditions:

a) The probability of exactly 10 patients are referred to an oncologist.  

b) The probability that between five and 15 inclusive are referred to an oncologist.

c) The probability that more than 10 are referred to an oncologist.

Solution:

a) The number of patients referred to an oncologist per month follows Poisson distribution with parameter λ = 16.

The probability of exactly 10 patients are referred to an oncologist is:

`P(X = 10) = e^(-λ) * (λ^x) / x!` = `e^(-16) * (16^10) / 10! = 0.036`

Therefore, the probability that exactly 10 patients are referred to an oncologist in a month is 0.036.

b) The probability that between five and 15 inclusive are referred to an oncologist is:

`P(5 ≤ X ≤ 15) = P(X ≤ 15) - P(X ≤ 4)``= ∑_(x=0)^4 (e^(-16) * (16^x) / x!) + ∑_(x=5)^15 (e^(-16) * (16^x) / x!)`≈ 0.98

Therefore, the probability that between five and 15 inclusive are referred to an oncologist in a month is 0.98.

c) The probability that more than 10 are referred to an oncologist is:

`P(X > 10) = 1 - P(X ≤ 10)` `= 1 - ∑_(x=0)^10 (e^(-16) * (16^x) / x!)` ≈ 0.873

Therefore, the probability that more than 10 patients are referred to an oncologist in a month is 0.873.

Step-by-step explanation:

The break-even point for bench production at the new plant is 4000 units.

The new production plant of Franco Cooperation will cost SAR 200000 to construct.

The variable costs of production of each bench are SAR 200. The selling price of each bench is SAR 250. We can find out the break-even point of bench production at the new plant by using the break-even formula.

Break-even point (in units) = Fixed costs / Contribution margin per unitWhere,

F = Fixed costs

P = Price per unit

V = Variable cost per unit

Contribution margin per unit = Price per unit - Variable cost per unit

First, let's calculate the contribution margin per unit.

P = Selling price of each bench = SAR 250V = Variable cost per unit = SAR 200

Contribution margin per unit = P - V= SAR 250 - SAR 200= SAR 50

Now, let's calculate the break-even point.

Fixed costs (F) = Cost of constructing the new plant= SAR 200000

Contribution margin per unit = SAR 50

Break-even point (in units) = F / Contribution margin per unit= SAR 200000 / SAR 50= 4000.

The break-even point for bench production at the new plant can be found by dividing the fixed costs by the contribution margin per unit.

The break-even point for bench production at the new plant is 4000 benches.

To determine the break-even point, we need to calculate the contribution margin per unit. Contribution margin per unit is the amount left over after deducting the variable costs from the selling price. It is also called unit contribution margin. Therefore, the contribution margin per unit = Selling price per unit - Variable cost per unit

= SAR 250 - SAR 200

= SAR 50

Now, we can use the formula to calculate the break-even point:

Break-even point = Fixed costs / Contribution margin per unit

Fixed costs = cost of new production plant

= SAR 200000

Contribution margin per unit = SAR 50

Therefore, Break-even point = SAR 200000 / SAR 50

= 4000 benches

The break-even point for bench production at the new plant is 4000 benches.
