Use the "mixed partials" check to see if the following differential equation is exact. If it is exact find a function F(x,y) who

Arturiano [62]

We have

$(-3xy^2+y)_y=--6xy+1$

and

$(-3x^2y+x)_x=-6xy+1$

so the equation is indeed exact. So we want to find a function $F(x,y)=C$ such that

$F_x=-3xy^2+y$

$F_y=-3x^2y+x$

Integrating both sides of the first equation wrt $x$ gives

$F(x,y)=-\dfrac32x^2y^2+xy+f(y)$

Differentiating both sides wrt $y$ gives

$F_y=-3x^2y+x=-3x^2y+x+f_y\implies f_y=0\implies f(y)=C$

So we have

$F(x,y)=-\dfrac32x^2y^2+xy+C=C$

$F(x,y)=\boxed{-\dfrac32x^2y^2+xy=C}$

3.4 is what percent of 4.25?<br><br> Enter your answer in the box.

Masteriza [31]

Step-by-step explanation:

100% = 4.25

1% = 100%/100 = 4.25/100 = 0.0425

how many % are 3.4 ?

we find this by calculating how often 1% (0.0425) fits into 3.4.

3.4 / 0.0425 = 80 %
