find f. f ‴(x) = cos(x), f(0) = 6, f ′(0) = 3, f ″(0) = 9

Answers

Answer 1

Therefore, the solution to the initial value problem is: f(x) = sin(x) + (9/2)x^2 - 4x + 6.

Taking the antiderivative of f‴(x) = cos(x), we get f′′(x) = sin(x) + C1, where C1 is the constant of integration.

Then, taking the antiderivative of f′′(x), we get f′(x) = -cos(x) + C1x + C2, where C2 is the constant of integration.

Finally, taking the antiderivative of f′(x), we get f(x) = sin(x) + C1/2 x^2 - C2x + C3, where C3 is the constant of integration.

Using the initial conditions f(0) = 6, f′(0) = 3, and f′′(0) = 9, we get:

f(0) = sin(0) + C3 = 6, so C3 = 6.

f′(0) = -cos(0) + C2 = 3, so C2 = 4.

f′′(0) = sin(0) + C1 = 9, so C1 = 9.

Therefore, the solution to the initial value problem is:

f(x) = sin(x) + (9/2)x^2 - 4x + 6.

after collecting eggs from his chickens, dale puts the eggs into cartons to sell. dale fills 15 1515 cartons and has 7 77 eggs left over. each carton holds 12 1212 eggs. how many eggs did dale collect? eggs

Answers

The total number of eggs Dale collected is 187 eggs.

To find the total number of eggs, you would use operations, specifically, multiplication and addition. First, multiply the number of cartons (15) by the number of eggs per carton (12). This gives you a total of 180 eggs (15 x 12) in the cartons.

In addition to the eggs in the cartons, Dale also has 7 eggs left over. To find the total number of eggs Dale collected, you simply add the number of leftover eggs (7) to the total number of eggs in the cartons (180). This results in a grand total of 187 eggs (180 + 7) that Dale collected from his chickens.

In summary, Dale collected 187 eggs in total: 180 eggs from filling 15 cartons with 12 eggs each and 7 additional leftover eggs.

If P(A)=0.54 then what value of P(B) the event A and B are complementary event

Answers

Answer:

P(B) = 0.46

Step-by-step explanation:

Probability

The complementary event of a given event A is defined as "not A" or the event that A does not occur.

For example, if A is defined as 'getting a job', then the complement of A is 'not getting a job'.

Event A and its complementary event (call it B) must satisfy:

P(A) + P(B) = 1

If we know P(A)=0.54, then

P(B) = 1 - P(A)

P(B) = 1 - 0.54

P(B) = 0.46

What is equation?

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

the equation that can be formed is as follows

1 Rial = $3.

Answers

To calculate E(NA^2), we need to find the expected value of the product of N and A^2.

Since A follows a gamma distribution with mean 1 and variance 2, we know that E(A) = 1 and Var(A) = 2. Additionally, for a gamma distribution with mean kθ, the shape parameter k represents the mean squared divided by the variance. In this case, we have mean(A^2) = Var(A) + [E(A)]^2 = 2 + 1^2 = 3. Now, using the properties of the Poisson distribution, we have E(N) = A and Var(N) = A. Therefore, E(NA^2) = E(N) * E(A^2) = A * mean(A^2) = A * 3 = 3A.  Since A has a mean of 1, we have E(NA^2) = 3 * 1 = 3.

Therefore, the correct answer is E(NA^2) = 3, which is not one of the given options.

Determine the class intervals: Class intervals are ranges of data values that are used to group the data in a histogram.

Count the frequency of data in each class interval: We need to count how many data points fall in each class interval.

We draw the x-axis, which represents the class intervals, and the y-axis, which represents the frequency of data in each class interval. Then, we draw rectangles on the x-axis, each representing a class interval, with a height equal to the frequency of data in that interval.

Finally, we need to label the x-axis as "Grades" and the y-axis as "Frequency." If needed, we can also include a scale on the x-axis to indicate the range of grades being displayed.

By following these steps, we can create a histogram that effectively displays the distribution of grades in the given data set.

books cost 50¢ and pamphlets 15¢ at the book sale. if mr. jones spent $90 and purchased 15 more pamphlets than he did books, how many pamphlets did he buy ?

Answers

Mr. Jones bought approximately 13 pamphlets.

In this problem, we have two types of items: books and pamphlets. Books cost 50¢ and pamphlets cost 15¢ at the book sale.

Let's use variables to represent the quantities we don't know. Let's say Mr. Jones bought x books and y pamphlets.

We are given two pieces of information:
1. Mr. Jones spent $90 on his purchases.
2. He bought 15 more pamphlets than books.

Now, let's set up the equations based on the given information.

First, let's consider the cost equation. The total cost of the books and pamphlets should equal $90.


The cost of x books is 50¢ * x, and the cost of y pamphlets is 15¢ * y. So, the equation becomes:
50x + 15y = 90

Next, let's consider the second piece of information. Mr. Jones bought 15 more pamphlets than books, which means y = x + 15.

Now, we have a system of two equations:
50x + 15y = 90
y = x + 15

To solve this system, we can use substitution or elimination method. Let's use substitution:

Substitute the value of y from the second equation into the first equation:
50x + 15(x + 15) = 90

Simplify the equation:
50x + 15x + 225 = 90
65x + 225 = 90

Subtract 225 from both sides:
65x = 90 - 225
65x = -135

Divide both sides by 65:
x = -135 / 65
x ≈ -2.08

Since we cannot have a negative number of books, we know that x must be a positive whole number. So, let's round x to the nearest whole number:
x ≈ -2

Now, substitute this value of x back into the second equation to find y:
y = x + 15
y ≈ -2 + 15
y ≈ 13

Therefore, Mr. Jones bought approximately 13 pamphlets.

1. The zero vector is in H.

2. H is closed under vector addition.

3. H is closed under scalar multiplication.

Now each property

1. The zero vector (0, 0) is in H since it lies on the unit circle.

2. To check closure under vector addition, suppose we have two vectors (x₁, y₁) and (x₂, y₂) in H. If we add them together, (x₁, y₁) + (x₂, y₂), the resulting vector will not necessarily lie on the unit circle. For example, if we add (1, 0) and (-1, 0), the result is (0, 0), which is not on the unit circle. Therefore, H is not closed under vector addition.

3. To check closure under scalar multiplication, suppose we have a scalar c and a vector (x, y) in H. If we multiply them, c × (x, y), the resulting vector will not necessarily lie on the unit circle. For example, if we multiply (1, 0) by 3, the result is (3, 0), which is not on the unit circle. Therefore, H is not closed under scalar multiplication.

answer in simplest radical form.

Answers

Answer:

A. 5

Step-by-step explanation:

The longest side of the right triangle is the hypotenuse and it is √61 units. The other legs of the triangle is x unit and (x + 1) units.

From Pythagoras theorem for right angle triangle, the square of the hypotenuse is equal to the sum of the square of the other sides of the triangle. This implies that:

(√61)² = (x)² + (x + 1)²

x² + x² + 2x + 1 = 61

2x² + 2x + 1 - 61 = 0

2x² + 2x -60 = 0

Dividing through by 2 gives:

x² + x - 30 = 0

x² + 6x - 5x - 30 = 0

x(x + 6) -5(x + 6) = 0

(x-5)(x+6) = 0

x-5 = 0 or x+6 = 0

x = 5 or x = -6

Have a good day :}

Zen Inc. manufactures two types of products, the G1 and the T1 model airplane. The manufacturing process consists of two principal departments: production and assembly. The production department has 58 skilled workers, each of whom works 7 hours per day. The assembly department has 25 workers, who also work 7-hour shifts. On an average, to produce a G1 model, Zen Inc. requires 3.5 labor hours for production and 2 labor hours for assembly. The T1 model requires 4 labor hours for production and 1.5 labor hours in assembly. The company anticipates selling at least 1.5 times as many T1 models as G1 models (this is the product mix). The company operates five days per week and makes a net profit of $130 on the G1 model, and $150 on the T1 model. Zen Inc. wants to determine how many of each model should be produced on a weekly basis to maximize net profit. If the numbers of G1 and T1 products produced each week are denoted as G and T respectively, the function that describes Zen, Inc.’s sales product mix for a week is?

Answers

Each model should be produced on a weekly basis to maximize net profit is $75,900.

What is Net profit?

In both business and accounting, net income or profit is an entity's revenue less cost of goods sold, costs, depreciation and amortisation, interest, and taxes for a certain accounting period.

As given,

Number of products sold:

T ≥ 1.5G

Maximize Profit Z = 150T + 130G

Labor Constraint:

Labor hours Available:

Production Department:

Number of labor hours available per day = 58 × 7 = 406

Number of days in a week = 5

Number of lobor ours available per week = 406 × 5 = 2030

Assembly Department:

Number of labor hours available per day = 25 × 7 = 175

Number of days in a week = 5

Number of labor hours available per week = 175 × 5 = 875.

Labor hours Required:

Labor hours required for G1 model:

Labor hours required at Production department = 3.5G

Labor hours required at assembly department = 2G

Labor hours required for T1 model:

Labor hours required at Production department = 4T

Labor hours required at Assembly department = 1.5T

Total labor hours required at Production department = 3.5G + 4T

Total labor hours required at Assembly department = 2G + 1.5T.

Constraint:

Labor hours required ≤ Labor hours Available.

Production department Labor constraint

3.5G + 4T ≤ 2030

Assembly department Labor constraint:

2G + 1.5T ≤ 875

The function:

Maximum Profit Z = 150T +130G

Constraint:

3.5G +4T ≤ 2030

2G + 1.5T ≤ 875

T ≥ 1.5G

Suppose that for example:

10.5G +12T = 6090

 16G + 12T = 7000

Solve both equations simultaneously,

5.5G = 7000 - 6090

5.5G = 910

    G = 910/5.5

    G = 363

Since, T > G

Hence,

T = 363,

G = 165

Calculate Profit:

150T + 130G = 150 × 363 + 130 × 165

                     = 54450 + 21450

                     = 75900

Hence, each model should be produced on a weekly basis to maximize net profit is $75,900.

Geckos are lizards with specialized toe pads that enable them to easily climb all sorts of surfaces. a research team examined the adhesive properties of 7 tokay geckos. below are their toe-pad areas (in square centimeters, cm2). 5.6 4.9 6.0 5.1 5.5 5.1 7.5 what is the value of the sample variance? _____ cm2 answer

Answers

Answer: 0.6763 cm∧2

Step-by-step explanation: Variance is one of the measures of dispersion which is the the second central moment in probability. It is defined as a measure of by how much the values in a data set differs from the mean of the values. Thus it is the average of the squares of the deviations from the mean as this ensures that both the negative and positive deviations do not cancel each other out.

The sample variance would be calculated as follows:

Population size is 7 (5.6 4.9 6.0 5.1 5.5 5.1 7.5)

Mean: Sum of samples / population size ;

(5.6 4.9 6.0 5.1 5.5 5.1 7.5) / 7 = 5.67

Applying the formula for variance: [ Summation (x - mean) ] / population size =( |5.6 - 5.67| + |4.9 - 5.67| + |6.0 - 5.67| + (|5.1 - 5.67|) * 2 + | 5.5 - 5.67| + |7.5 - 5.67|) / 7 = 0.6763 cm^2

Work out an expression for the nth term of the sequence.
The nth term is n+9

Answers

Answer:

9n + 2.

Step-by-step explanation:

This is arithmetic with common difference d = 9.

nth term = a1 + d(n - 1)     (a1 = 11) 11 + 9n - 9

= 11 + 9(n - 1)

= 9n + 2.

The correct answer is 9n+2

A physical therapist wants to determine the difference in the proportion of men and women who participate in regular sustained physical activity. What sample size should be obtained if shewishes the estimate to be within twopercentage points with 90​%​confidence, assuming that​

(a) sheuses the estimates of 21. 9​%male and 18. 5​%female from a previous​ year?​

(b) shedoes not use any prior​ estimates?

A. N = ____

B. N = ____

Answers

Number of sample within two percent is 1157. Number of sample does not use any prior estimates are 1691.

How to calculate data sample?

As per data given

E = 2% = 0.02

male m = 21.9% = 0.219

female f =  18.5% = 0.185

Critical value Z = 90% = 1.645

To calculate data sample use this function: n = (Z / E )² × m(1-m) + f ( 1-f ), so:

n = (1.645 / 0.02 )² × 0.219(1-0.219) + 0.185 ( 1-0.185 )

n = 1157.24029994 = 1157 number of sample

To calculate number of sample does not use any prior estimates use this function: n = (Z / E )² × m(1-m) + f ( 1-f ). since the data is divided into two category so m = 0.5 and f = 0.5. So the calculation will be:

n = (1.645/ 0.02)² × 0.5(1-0.5) + 0.5 ( 1-0.5 )

n = 1691.515625 = 1691 sample.
