The line that contains an example of assonance is C. He fell asleep under the oak tree, feeling fine.

<h3>What is Assonance?</h3>

This refers to the similarity of sounds that can be found in nearby words in a sentence, between their vowels and/or consonants.

Furthermore, alliteration means the occurrence of similar words or sounds in a sentence at the beginning of closely connected words.

With this in mind:

The line that contains an example of alliteration is A. Tom tried learning a new tune.
The line that contains an example of consonance is D. Phillipe hoped for a copper cup.

Which fraction is equivalent to a whole number select all that apply? 9/3, -16/8, 7/0, -5/3, 0/5

vredina [299]

9/3 = 3 So it is equivalent to a whole number
-16/8 = -2 which is a whole number

The rest are not equal to whole numbers if you work them out

Evaluate the Riemann sum for f(x) = 3x − 1, −6 ≤ x ≤ 4, with five subintervals, taking the sample points to be right endpoints.

Verdich [7]

Answer:

The Riemann sum equals -10.

Step-by-step explanation:

The right Riemann Sum uses the right endpoints of a sub-interval:

$\int_{a}^{b}f(x)dx\approx\Delta{x}\left(f(x_1)+f(x_2)+f(x_3)+...+f(x_{n-1})+f(x_{n})\right)$

where

$\Delta{x}=\frac{b-a}{n}$

To find the Riemann sum for $\int\limits^{4}_{-6} {3x-1} \, dx$ with n = 5 rectangles, using right endpoints you must:

We know that a = -6, b = 4 and n = 5, so

$\Delta{x}=\frac{4-\left(-6\right)}{5}=2$

We need to divide the interval −6 ≤ x ≤ 4 into n = 5 sub-intervals of length $\Delta{x}=2$

$a=\left[-6, -4\right], \left[-4, -2\right], \left[-2, 0\right], \left[0, 2\right], \left[2, 4\right]=b$

Now, we just evaluate the function at the right endpoints:

$f\left(x_{1}\right)=f\left(-4\right)=-13=-13$

$f\left(x_{2}\right)=f\left(-2\right)=-7=-7$

$f\left(x_{3}\right)=f\left(0\right)=-1=-1$

$f\left(x_{4}\right)=f\left(2\right)=5=5$

$f\left(x_{5}\right)=f(b)=f\left(4\right)=11=11$

Finally, just sum up the above values and multiply by 2

$2(-13-7-1+5+11)=-10$

The Riemann sum equals -10

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 $y(x)$ :

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

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

Lucy earns $15.75 per hour. Last week she worked 25 hours. What is her gross pay:

Bumek [7]

Lucy's gross pay per week is $393.75.

Lance's tax payment amount is $10983.

Lance's net pay is $41,317.

Lance's every paycheck of two will be around $2179 per month.

1) Lucy earns $15.75 per hour.

Last week she worked 25 hours.

Solution:

Lucy's gross pay per week is $15.75 * 25 hours.

Lucy's gross pay per week = 15.75 * 25 = $393.75

2) Lance has a yearly salary of $52,300

He pays 21% as taxes.

Solution:

a) Lance tax pay amount = 21/100*52,300 = $10983

b) Lance's net pay = $52,300 - $10983 = $41,317

c) Per month salary = $52,300/12 = $4358

Each paycheck will be 4358/2 = $2179
