− 2 y ' ' − 4 y ' + 1 y = 0 : over-damped
1 y ' ' + 7 y ' + 5 y = 0: over-damped
Step-by-step explanation:
Using the characteristic equation you can express a differential equation of order n as an algebraic equation of degree n:
This differential equation will have a characteristic equation of the form:
Now, you can classify the solution for a differential equation using a simple method. In order to do it, you just need to use the discriminant.
- If the discriminant is greater than zero, the solution is over-damped
- If the discriminant is less than zero, the solution is under-damped
- If the discriminant is equal to zero, the solution is critically damped
So, given the differential equation:
Which has characteristic equation of the form:
The quadratic polynomial of the form:
Has discriminant:
In this case:
So:
In this case:
Therefore the solution is over-damped.
Now, given the differential equation:
Which has characteristic equation of the form:
The quadratic polynomial of the form:

In this case:
Therefore the solution is over-damped.
Answer: 20
Step-by-step explanation:
Let 's complete our quadrilateral to a rectangle ; and subtract from it the area highlighted in red
Answer:
Look at the number line.
Step-by-step explanation:
Step 1: Draw a number line.
Step 2: Mark -4 on the number line.
Step 3: Here we have to subtract 8, therefore, from -4 move 8 units left, we end up at -12.
That is the answer. Here is the picture.
Hope this will help you.
Thank you.
