A circle in the XY-plane has center (5, 7) and radius 2. Which of the following is an equation of the circle?
MAXImum [283]

Answer: A, because the equation of a circle is (x-h)^2+(y-k)^2=r^2. So, if the point of the center is (5,7) and the radius 2 , then on the equation should be changed as negative and the radius should be multiplied as 4, which is (x-5)^2+(y-7)^2=4

en un maratòn participan corredores de todos los continentes 5/6 de los corredores son europeos se sabe que los americanos son l
Marysya12 [62]

Usando proporciones, se encuentra que 400 africanos han participado.

En total, hay x participantes.

\frac{5}{6} de los corredores son europeos, o sea:

E = \frac{5x}{6}

Los americanos son la dècime parte de los europeos, o sea:

Am = \frac{1}{10}E = \frac{5x}{60} = \frac{x}{12}

Los africanos son la quinta parte de los americanos, o sea:

Afr = \frac{1}{5}Am = \frac{x}{60}

En la carrera han inscritos 24 000 participantes, o sea, x = 24000. Por eso, la cantidad de africanos es:

Afr = \frac{x}{60} = \frac{24000}{60} = 400

Please just give me the actual answer to this question Or at least help me understand because I don't get it and I have looked i
iren [92.7K]

Step-by-step explanation:

To begin with, this is an English question.

Here is what ethos, pathos and logos mean:

Ethos: writing an ethos response requires an argument that includes trustworthy language.

Pathos: writing a pathos response requires an argument that includes emotion and make the reader use their feelings while reading the piece.

Logos: writing a logos response requires an argument that includes facts and logic to ensure the reader that what you are saying is true and reasonable.

In this task, you must use ethos, pathos, and logos separately and try to convince your parents to stay home by yourself.

example:

Logos: Staying home by myself can teach me great responsibility and prepare me for the future. It is much better for me to learn how to take care of myself and what to do in case of an emergency. It is a great opportunity to practice independency. My grandparents would probably rather be undisturbed and I don't wish to trouble them. I am getting older and need to learn how to take care of everything alone. I think I can handle it and is good training. Furthermore, it is a good chance to have some alone time as it is shown that being alone can be healthier for individuals. To sum up, staying home alone is a responsibility I need to practice and I am ready for it.

I hope that helped

How to solve derivative of (sin3x)/x using first principle ​
Leona [35]

\dfrac{d}{dx}(\dfrac{\sin(3x)}{x})

First we must apply the Quotient rule that states,

(\dfrac{f}{g})'=\dfrac{f'g-g'f}{g^2}

This means that our derivative becomes,

\dfrac{\dfrac{d}{dx}(\sin(3x))x-\dfrac{d}{dx}(x)\sin(3x)}{x^2}

Now we need to calculate \dfrac{d}{dx}(\sin(3x)) and \dfrac{d}{dx}(x)

\dfrac{d}{dx}(\sin(3x))=\cos(3x)\cdot3

\dfrac{d}{dx}(x)=1

From here the new equation looks like,

\dfrac{3x\cos(3x)-\sin(3x)}{x^2}

And that is the final result.

Hope this helps.
