Question Consider, The motion of a a damped harmonic oscillator is described by x′′ x ″ + bx′ b x ′ + kx=0 k x = 0 , where b is greater than or equal to 0 A) Rewrite as a two dimensional linear system. x′=y x ′ = y y′ y ′ = - (by+kx) ( b y + k x ) B) Sketch the analogue of the trace-determinant plane in the bk-plane. That is, identify the regions in the relevant portion of the bk-plane where the corresponding system has similar phase portraits. I have cut out most of my answer etc as it seems to of merely confused people, how does one answer this question?

Can Anybody Help me?
Leviafan [203]

Answer:

x=8, y=-1

Step-by-step explanation:

The figure is said to be a rectangle, which means opposite sides have to be equal in length. From this, we can write a system of equations:

5x-2y=42

2x+3y=13

There are a number of ways to solve this but I'll go with elimination--that means you need to try to remove one variable first by manipulating the equations and solve for the other variable. Then you use the solution to solve for the variable you initially removed. That sounds confusing, but let me show you how to do it.

If you multiply the first equation by 3 and the second equation by 2, you'll have have:

15x-6y=126

4x+6y=26

Now, we can add these two equations. The y will cancel out, so we can easily solve for x.

19x=152

x=8

Use this value of x to substitute back into either of the original equations to find y.

5(8)-2y=42

40-2y=42

-2y=2

y=-1

Explain? How to slove it
Neko [114]
The answer is F because you use the square's measurements as the base of each triangle then multiply each triangle then divide by 2. The multiply by 4 because there are four triangles and multiply 12 by 12 to get 144 because it is the base and the height of the square.
