Answer:

A= 2 B= 9/10 (0.9)

Step-by-step explanation:

to find the gradients, we need to use the formula:

rise / run ---> which is basically counting the "boxes" in both of the x and y axis and divide them together (rise=y, run=x)

like that

x axis=5 y=10 ---> then we use the formula (rise/run) 10/5= 2

x axis=10 y=9 ---> then we use the formula (rise/run) 9/10= 0.9

but since B is going downhill, it'll be -0.9

Solve the following differential equation: (2x+5y)dx+(5x−4y)dy=0 *Hint: they are exact C=.

Tpy6a [65]

Answer with Step-by-step explanation:

The given differential equation is

$(2x+5y)dx+(5x-4y)dy=0$

Now the above differential equation can be re-written as

$P(x,y)dx+Q(x,y)dy=0$

Checking for exactness we should have

$\frac{\partial P}{\partial y}=\frac{\partial Q}{\partial x}$

$\frac{\partial P}{\partial y}=\frac{\partial (2x+5y)}{\partial y}=5$

$\frac{\partial Q}{\partial x}=\frac{\partial (5x-4y)}{\partial x}=5$

As we see that the 2 values are equal thus we conclude that the given differential equation is exact

The solution of exact differential equation is given by

$u(x,y)=\int P(x,y)dx+\phi(y)\\\\u(x,y)=\int (2x+5y)dx+\phi (y)\\\\u(x,y)=x^2+5xy+\phi (y)$

The value of $\phi (y)$ can be obtained by differentiating u(x,y) partially with respect to 'y' and equating the result with P(x,y)

$\frac{\partial u}{\partial y}=\frac{\partial (x^2+5xy+\phi (y)))}{\partial y}=Q(x,y))\\\\5y+\phi '(y)=(5x-4y)\\\\\phi '(y)=5x-9y\\\\\int\phi '(y)\partial y=\int (5x-9y)\partial y\\\\\phi (y)=5xy-\frac{9y^2}{2}\\\\\therefore u(x,y)=x^2+10xy-\frac{9y^2}{2}+c$

What is the average rate of change of the function on the interval from x=0 to x=2?

vfiekz [6]

So what I would do is find the slope from (0,f(0)) to (2,f(2))

f(0)=250
f(2)=62.5

(0,250) and (2,62.5)
find the slope
(y2-y1)/(x2-x1)
(62.5-250)/(2-0)=187.5/2=-93.75

answer is -93.75
