Determine if the given differential equation is exact (e^2y-y cos xy)dx+(2xe^2 y-cos xy+2y)dy=0

rewona [7]

$\dfrac\partial{\partial y}\left[e^{2y}-y\cos xy\right]=2e^{2y}-\cos xy+xy\sin xy$

$\dfrac\partial{\partial x}\left[2xe^{2y}-y\cos xy+2y\right]=2e^{2y}+y\sin xy$

The partial derivatives are not equal, so the equation is not exact.

Which equation, in slope-intercept form, represents the relationship shown in this table?

postnew [5]

Answer:

$y=2x+8$

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take two points from the data

(0,8) and (1,10)

substitute in the formula

$m=\frac{10-8}{1-0}$

$m=\frac{2}{1}$

$m=2$

step 2

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$m=2$

$b=8$ ----> the y-intercept is the point (0,8)

substitute

$y=2x+8$

Hmmm the increase, wel is just the difference 367 - 312, which is 55.

now, if we take 312 to be the 100%, what is 55 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
312&100\\
55&p
\end{array}\implies \cfrac{312}{55}=\cfrac{100}{p}\implies p=\cfrac{55\cdot 100}{312}$
