Use the "mixed partials" check to see if the following differential equation is exact. if it is exact find a function f(x, y) whose differential, df(x, y) gives the differential equation. that is, level curves f(x, y)=c are solutions to the differential equation: dydx=3x3+2y−2x−y2 first rewrite as m(x, y)dx+n(x, y)dy=0 where m(x, y)= equation editor equation editor , and n(x, y)= equation editor equation editor . if the equation is not exact, enter not exact, otherwise enter in f(x, y) as the solution of the differential equation here

The differential equation is not exact.

Step-by-step explanation:

We can write the differential equation as

with

to check whether the differential equation is exact, we must verify that

But

whereas

and we can see

So the differential equation is not exact.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
