To find the particular solution of the differential equation y''' - 4y' = t + 3cos(t) + e^(-2t), we assume a general form for the solution. After solving, we obtain y(t) = -1/2t^2 + (1/2)sin(t) - (1/8)e^(-2t) + (1/16)te^(-2t) + C1 + C2t + C3e^(-2t), where C1, C2, and C3 are arbitrary constants.

To find the particular solution of the given differential equation y''' - 4y' = t + 3cos(t) + e^(-2t), we will use the method of undetermined coefficients.

Guess the form of the particular solution.

Since the right-hand side of the equation consists of a polynomial term (t) and trigonometric terms (cos(t)), as well as an exponential term (e^(-2t)), we will guess a particular solution of the form:

y_p(t) = At^2 + Bt + Ccos(t) + De^(-2t)

Calculate the derivatives of the guessed solution.

y'_p(t) = 2At + B - Csin(t) - 2De^(-2t)

y''_p(t) = 2A - Ccos(t) + 4De^(-2t)

y'''_p(t) = Csin(t) + 8De^(-2t)

Substitute the guessed solution and its derivatives into the original differential equation.

Substituting into the equation:

(Csin(t) + 8De^(-2t)) - 4(2A - Ccos(t) + 4De^(-2t)) = t + 3cos(t) + e^(-2t)

Simplifying the equation, we get:

Csin(t) + 8De^(-2t) - 8A + 4Ccos(t) - 16De^(-2t) = t + 3cos(t) + e^(-2t)

Collect like terms and solve for the coefficients.

Matching the coefficients of the terms on both sides, we have:

Csin(t) + 8De^(-2t) = 0 (1)

-8A + 4Ccos(t) - 16De^(-2t) = 3cos(t) (2)

0t + 0 + 0 - 8A + 0 - 16De^(-2t) = t + e^(-2t) (3)

From equation (1), we have C = 0, and from equation (2), we get C = 3/4.

Equating the exponential terms in equation (3), we have -16De^(-2t) = e^(-2t), which gives D = -1/16.

Finally, from equation (3), we find -8A = t, which implies A = -t/8.

Therefore, the particular solution is:

y_p(t) = (-t/8)t^2 + Bt + (3/4)cos(t) - (1/16)e^(-2t)

where B is an arbitrary constant.

Answer:

The given differential equation is a third-order, non-homogeneous, linear differential equation. To find its particular solution, we can use the method of undetermined coefficients. This method involves assuming a form for the particular solution based on the form of the non-homogeneous term, and then determining the values of the coefficients by substituting the assumed form into the differential equation.

In this case, the non-homogeneous term is `t + 3cos t + e^-2t`. Since this term contains a polynomial of degree 1, a cosine function, and an exponential function, we can assume that the particular solution will have the form `y_p = At + B + Ccos t + Dsin t + Ee^-2t`, where `A`, `B`, `C`, `D`, and `E` are constants to be determined.

To determine the values of these constants, we can substitute the assumed form for `y_p` into the given differential equation and equate coefficients. This will result in a system of linear equations that can be solved for `A`, `B`, `C`, `D`, and `E`. Once these values are determined, we can write down the particular solution as `y_p = At + B + Ccos t + Dsin t + Ee^-2t`.

Answer:

\( 75= 119 -1.96 \sigma\)

\( \sigma = \frac{75-119}{-1.96}= 22.45\)

And tha's equivalent to use this formula:

\( 163= 119 +1.96 \sigma\)

\( \sigma = \frac{163-119}{1.96}= 22.45\)

Step-by-step explanation:

For this case the 95%of the values are between the following two values:

(75 , 163)

And for this case we know that the variable of interest X "length of a movie" follows a normal distribution:

\( X \sim N( \mu, \sigma)\)

We can estimate the true mean with the following formula:

\(\mu = \frac{75+163}{2}= 119\)

Now we know that in the normal standard distribution we know that we have 95% of the values between 1.96 deviations from the mean. We can find the value of the deviation with this formula:

\( 75= 119 -1.96 \sigma\)

\( \sigma = \frac{75-119}{-1.96}= 22.45\)

And tha's equivalent to use this formula:

\( 163= 119 +1.96 \sigma\)

\( \sigma = \frac{163-119}{1.96}= 22.45\)

D. 3 and -4

Step-by-step explanation:

Given the expression, x² - x - 12, let's factorise to find the value of p and q using the table, for which we would have the expression simplified as (x + p)(x + q)

From the table, let's find the values of p and q that would give us -12 when multiplied together, and would also give us -1 when summed together.

Thus, from the table given, the row containing the values of p(3) and q(-4) gives us = -1 (p+q) . p = 3, q = -4 would be our values to use to factor x² - x - 12, as multiplying both will also give us "-12".

Thus, x² - x - 12 would be factorised or simplified as (x + 3)(x - 4)

Therefore, the answer is: D. 3 and -4

The company spends making tablets each year, you can multiply the number of tablets by the cost per tablet so the company spends about $500 million making tablets each year.

Its origins lie in the Latin word moneta, which was given to the Roman goddess Juno, at whose temple or close by, or both, the Romans first started minting coins approximately 300 BCE.

We may multiply the quantity of tablets produced by the cost of producing each tablet to see how much money the company spends annually making tablets:

Total cost = Production of tablets x Price per tablet

Number of tablets produced =\(2.5 × 10^7\)

Cost per tablet = $20

Therefore, the total cost = \(2.5 × 10^7 × $20 = $5 × 10^8\)

As a result, the corporation spends over $500 million annually producing tablets.

Part A:

We are given that the height of a tree in a scale drawing is 3.75 inches. The scale of the drawing is 1 inch: 50 feet.

To find the height of the actual tree, we can use the ratio of the drawing scale to the real-life scale. For every 1 inch on the drawing, there are 50 feet in real life.

Therefore, we can set up a proportion:

\($\frac{1 \ \text{inch}}{50 \ \text{feet}} = \frac{3.75 \ \text{inches}}{x \ \text{feet}}$where $x$ is the height of the actual tree in feet.We can solve for $x$ by cross-multiplying:$1 \ \text{inch} \cdot x = 3.75 \ \text{inches} \cdot 50 \ \text{feet}$$x = \frac{3.75 \ \text{inches} \cdot 50 \ \text{feet}}{1 \ \text{inch}} = 187.5 \ \text{feet}$Therefore, the height of the tree is $\boxed{D \ 187.5 \ \text{ft}}$.\)

\(Part B:We are now given a new scale drawing where the height of the same tree is 6 inches. We need to find the new scale.Since the tree's height in the new drawing is different, we can use a new proportion to find the new scale.Let the new scale be $1$ inch to $x$ feet. We can set up a proportion:\)

\($\frac{1 \ \text{inch}}{x \ \text{feet}} = \frac{6 \ \text{inches}}{187.5 \ \text{feet}}$where $187.5$ feet is the height of the tree in real life.We can solve for $x$ by cross-multiplying:$1 \ \text{inch} \cdot 187.5 \ \text{feet} = 6 \ \text{inches} \cdot x \ \text{feet}$$x = \frac{1 \ \text{inch} \cdot 187.5 \ \text{feet}}{6 \ \text{inches}} = 31.25 \ \text{ft}$Therefore, the new scale is $\boxed{1 \ \text{inch} : 31.25 \ \text{ft}}$.\)

Answer:

Step-by-step explanation:

Part A:

We can use a proportion to solve for the height of the tree:

1 inch on the drawing represents 50 feet in real life.

So, 3.75 inches on the drawing would represent:

3.75 inches * (50 feet/1 inch) = 187.5 feet

Therefore, the height of the tree is 187.5 feet.

The answer is D) 187.5 ft.

Part B:

The ratio of the height of the tree on the new scale drawing to its actual height must be the same as the ratio of the height of the tree on the original scale drawing to its actual height.

Let the new scale be 1 in. : x feet.

Then, we have the proportion:

1 in. / 50 ft. = 6 in. / (x) ft.

Solving for x, we get:

x = (6 in. * 50 ft.) / 1 in.

x = 300 ft.

Therefore, the new scale is 1 in. : 300 ft.

The answer is 1 in. : 300 ft.

Given statement solution is :-  For the third week of April, Patricia's:

Regular pay amount is $476.

Overtime pay is $231.45.

Gross pay is $707.45.

To calculate Patricia's pay for the third week of April, we'll need to determine her regular pay, overtime pay, and gross pay.

Regular Pay:

Patricia worked 53 hours, but only 40 hours are considered regular hours. Therefore, the regular pay is calculated as follows:

Regular Pay = Regular Hours x Hourly Rate

Regular Pay = 40 hours x $11.90/hour

Regular Pay = $476

Overtime Pay:

Since Patricia worked 53 hours in total and 40 of those are regular hours, the remaining 13 hours are considered overtime hours. Overtime pay is calculated by multiplying the overtime hours by 1.5 times the hourly rate.

Overtime Pay = Overtime Hours x (Hourly Rate x 1.5)

Overtime Pay = 13 hours x ($11.90/hour x 1.5)

Overtime Pay = 13 hours x $17.85/hour

Overtime Pay = $231.45

Gross Pay:

Gross Pay is the sum of Regular Pay and Overtime Pay.

Gross Pay = Regular Pay + Overtime Pay

Gross Pay = $476 + $231.45

Gross Pay = $707.45

Therefore, for the third week of April, Patricia's:

Regular pay amount is $476.

Overtime pay is $231.45.

Gross pay is $707.45.

The use of volunteer sampling means that the result of the survey is potentially misleading.

Volunteer sampling is a sampling technique in which each participant in the sample opts to join the research, as is the case for this problem, as each participant opted to join in the project to compare their cold lengths.

The drawback of this type of sampling is that it should contain lots of participants that share similar characteristics, such as desiring to weight/diet, and this may influence their recovery to cold. The participants also may lie, which can cause misleading results to the study.

Options to remove misleading conclusions is to use a different type of sampling, such as stratified sampling, as groups of people that are either short or long sleepers are compared to reach a conclusion.

Given the word problem, we can deduce the following information:

1. A triangular plot of land has angles 46° and 58°.

2. The side opposite the 46° is 35 m long.

To determine the length of the fence to enclose the entire plot of land, we make a figure of the triangular plot first:

where:

x= the third angle

a= side opposite of 58°

b= side opposite of x°

Since the sum of the interior angles of a triangle is 180°, we can get the value of x by:

x=180-46-58

x=76°

Next, we use the Law of Sines proportion as shown:

Then, we find the value of a:
