Answer:
square root 3 that is a the answer
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?
Answer:
I would say the answer is A) y = x + 3
Step-by-step explanation:
Reason is, if you replace x with the different numbers listed under x and add 3 to them, they would equal the corresponding numbers listed under y.
<u>For example</u>:
x-value

(5) = (2) + 3
⬆
y-value
Hope this helps :)
You're not gonna like it. I think both I and III are true, so none of the choices shown. Choice E: I and III.
I. H and J are points, and any two points are on some line, so collinear. TRUE.
II. L is between R and K. Betweeness needs collinearity, which we don't have here. FALSE.
III. R, J and N are coplanar. Any three points lie in some plane. TRUE.
