Solve the differential equations dy/dx=((xy^2)+x)/y
arsen [322]

\displaystyle \dfrac{dy}{dx}=\dfrac{xy^2+x}{y}\\ \dfrac{dy}{dx}=\dfrac{x(y^2+1)}{y}\\ \dfrac{y}{y^2+1}\, dy=x\, dx\\ \int \dfrac{y}{y^2+1}\, dy=\int x\, dx\\ \dfrac{\ln (y^2+1)}{2}=\dfrac{x^2}{2}+C\\ \ln(y^2+1)=x^2+C\\ y^2+1=e^{x^2+C}\\ y^2=e^{x^2+C}-1\\ y=\sqrt{e^{x^2+C}-1} \vee y=-\sqrt{e^{x^2+C}-1}\\ \boxed{y=\sqrt{Ce^{x^2}-1} \vee y=-\sqrt{Ce^{x^2}-1}}\\

Likurg_2 [28]

Answer: The percent of people who were interested in black holes last year was 70%.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

  • People interested in black holes this year: 62%

If the number is down from the previous year by 8%, to calculate the percent of people who were interested last year we simply have to add the 8% loss to the actual 62 %.

So, mathematically speaking:

  • 62%+8%=70%

In conclusion, the percent of people who were interested in black holes last year was 70%.

Feel free to ask for more if it´s necessary or if you did not understand something.
