Answer:
not enough info to solve
Step-by-step explanation:
Let's say we have a one parameter family:
dydt=y2+kdydt=y2+k
I want to find the bifurcation value. What does this mean?
It seems like I need to set dy/dt = 0 and then solve for k, but then I get a negative square root:
0=y2+k0=y2+k
y2=−ky2=−k
y=sqrt(−k)y=sqrt(−k)
or
k=−y2
0.05 simple. Move the spaces to the left as the number of 0 in the decimal. Two 00 so move two space to the left.
Option A is the relationship which shows a direct variation.
Step-by-step explanation:
The direct variation is a relationship between two variables in which one is the multiple of the other. It is given by the relation
Option A:
For and ,
For and ,
Since, the constant k is equal for all the values of x and y in the table, this relationship is a direct variation.
Option B:
For and ,
For and ,
Since, the values of constant k is not equal for all the values of x and y in the table, this relationship is not a direct variation.
Option C:
For and
For and
Since, the values of constant k is not equal for all the values of x and y in the table, this relationship is not a direct variation.
Option D:
For and
For and
Since, the values of constant k is not equal for all the values of x and y in the table, this relationship is not a direct variation.
Thus, Option A is the relationship which shows direct variation.
