Find an explicit solution to the Bernoulli equation. y'-1/3 y = 1/3 xe^xln(x)y^-2

NNADVOKAT [17]

$y'-\dfrac13y=\dfrac13xe^x\ln x\,y^{-2}$

Divide both sides by $\dfrac13y^{-2}(x)$ :

$3y^2y'-y^3=xe^x\ln x$

Substitute $v(x)=y(x)^3$ , so that $v'(x)=3y(x)^2y'(x)$ .

$v'-v=xe^x\ln x$

Multiply both sides by $e^{-x}$ :

$e^{-x}v'-e^{-x}v=x\ln x$

The left side can be condensed into the derivative of a product.

$(e^{-x}v)'=x\ln x$

Integrate both sides to get

$e^{-x}v=\dfrac12x^2\ln x-\dfrac14x^2+C$

Solve for $v(x)$ :

$v=\dfrac12x^2e^x\ln x-\dfrac14x^2e^x+Ce^x$

Solve for $y(x)$ :

$y^3=\dfrac12x^2e^x\ln x-\dfrac14x^2e^x+Ce^x$

$\implies\boxed{y(x)=\sqrt[3]{\dfrac14x^2e^x(2\ln x-1)+Ce^x}}$

Ms.Shrewsberry gave out a quiz to all 132 of her students. Of all of the students that took the quiz 3/11 of received an A as a

Olegator [25]

Answer:

36 students got an'A' grade in the quiz.

Step-by-step explanation:

Given:

Total number of students taking the quiz = 132

Fraction of students getting an 'A' grade = $\frac{3}{11}$

To find the number of students getting an 'A' grade.

Solution:

In order to find the number of students who got an 'A' grade in the quiz, we will find the fractional part who got an 'A' of the total students taking the quiz.

The fraction of students getting an 'A' is = $\frac{3}{11}$

Thus, total number of student getting an 'A' is :

⇒ $\frac{3}{11}$ of $132$

⇒ $\frac{3}{11}\times 132$

⇒ $\frac{396}{11}$

⇒ 36 (Answer)

Exciting Entertainment

Free_Kalibri [48]

We can deduce that the student's gender provides information about their entertainment choices.

Given the following data:

Expenses on digital music = $2.6 billion dollars.

Expenses on video games = $24.7 billion dollars.

<h3>Describing and analyzing the data.</h3>

The data was gathered from a random survey which was conducted by sixth-grade students to determine the number of digital music (songs) that was downloaded by each student to their respective media player in the past two months as shown in the table in the image attached below.

<h3>What is a median?</h3>

A median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged from the least to greatest (ascending order) or greatest to least (descending order).

For the girls:

Median = 50.

For the boys:

Median = 33.

A mean refers to a ratio of the sum of the total number in a data set to the frequency of the data set.

For the girls:

Mean = 46.

For the boys:

Mean = 34.

In this context, we can deduce that the student's gender provides information about their entertainment choices.

Emily earned a grade of 80% on a math test that had 20 problems. How many problems on this test did she answer correctly? If Joh

Oxana [17]

Someone getting all 20 problems correct would earn a grade of 100%. Thus, each correct question counts 5%.

If Emily earned 80%, then the number of problems she got correct was (80% / 100%).

Simplify this result. It represents the fraction of 20 questions that Emily got correct. Multiply your result by 20 to find the actual number of questions that E. got correct.
