The given differential equation is not exact, if we convert it to an exact one, we get:
<h3>
Is the differential equation exact or not?</h3>
A differential equation:
Is exact only if:
In this case, we have:
If we differentiate, we will get:
So, to convert this to an exact differential equation, we need to add a factor 2 to N, this will give:
This is, in fact, an exact differential equation.

Answer:
the area is 10 feet by 10 feet, 100 feet²
subtract the area of the circle from this.
you get it by A = r² * pi
so 5² * 3.14159...
=78.5398163397
100-78.5398163397
is roughly 21.46 square feet
Answer:
1000 : 199 : 271
Step-by-step explanation:
A rations a form of comparison between different variables or quantities.
We want to compare how much water, sucrose and saline solution are used to make the medicine.
The amount of water used is 1 L = 1000 mL
The amount of sucrose used is 199 mL
The amount of saline solution used is 271 mL
Therefore, the ratio of water to sucrose to saline solution is:
1000 : 199 : 271
This is the simplest form because 1000, 199 and 271 do not have any common factors.
