Solve the differential equation 3ydx+(xy+5x)dy=0

Brrunno [24]

The ODE is separable:

$3y\,\mathrm dx+(xy+5x)\,\mathrm dy=0\implies x(y+5)\,\mathrm dy=-3y\,\mathrm dx\implies\dfrac{y+5}y\mathrm dy=-\dfrac3x\,\mathrm dx$

Integrating both sides gives

$\displaystyle\int\left(1+\frac5y\right)\,\mathrm dy=-3\int\frac{\mathrm dx}x\implies y+5\ln|y|=-3\ln|x|+C$

Is this equation true? 1.2(2x-5)=2/5(2x-15)+1.6x

kobusy [5.1K]

Answer:

no, there is an infatuate amount of solutions

Step-by-step explanation:

1.2(2x-5)=2/5(2x-15)+1.6x

2.4x -6 = .8x -6 +1.6

2.4 -6 = 2.4-6

0=0 ( infatuate)

the weight of an object on mars varies directly as the weight of the object on earth a 90 pound object on earth weighs 34 pounds

Mariulka [41]

We have been given that the weight of an object on the mars varies directly as the weight of the object on earth.

Let y be weight of an object on Mars and x be weight of an object on Earth.

$\\
y=kx$

We have been given that the weight of an object on Mars is 34 pounds and weight of the same object on Earth is 90 pounds.

Putting the given values in equation we get

$\\
34=k(90)\\
\\
k=\frac{34}{90}=\frac{17}{45}$

Therefore, our equation now becomes

$\\
y= \frac{17}{45}x$

Now we have been given that the weight of an object on Earth is 135 pounds and we have to find the weight of the same object on Mars,

We have been given that $\\
x=135$

Putting the given values in our equation we get

$\\
y= \frac{17}{45}(135)=\frac{17\cdot 135}{45}=17\cdot 3 = 51$

Therefore weight of the object on Mars will be 51 pounds.

In triangle PQR, measurement P = 7x+8 , measurement Q = 8x-10, and measurement R = 7x+6 . List the sides in order from shortest

astra-53 [7]

Answer:

QRP

Q = 8x-10

R = 7x+6

P = 7x+8

Step-by-step explanation:

Let x be any positive integer, say x=2

P=7x+8=(7*2)+8=22 units

Q=8x-10=(8*2)-10=6 units

R=7x+6=(7*2)+6=20 units

From the above, Q is the shortest and P is the longest side. Therefore, the sides arranged from shortest to longest will be Q, R, P
