Answer:
The value of the intercept is a=216.
Step-by-step explanation:
We define "s" as the number of scarecrows and "C" the number of crops eaten.
The farmer finds the linear regression equation:
We have a linear function, for which we only know the slope (m=0.8) and a point within it (when s=20, C=200).
We can find a replacing the variables C asn s with the known point (20, 200):
The value of the intercept is a=216.
Answer:
Step-by-step explanation:
1 ) Given that
For a non homogeneous part , we assume the particular solution is
2 ) Given that
For a non homogeneous part , we assume the particular solution is
3 ) Given that
y′′ + 4y′ + 20y = −3sin(2x)
For a non homogeneous part −3sin(2x) , we assume the particular solution is
4 ) Given that
y′′ − 2y′ − 15y = 3xcos(2x)
For a non homogeneous part 3xcos(2x) , we assume the particular solution is
Answer:
The graph is shown below.
Step-by-step explanation:
Given:
The inequality of a line to graph is given as:
In order to graph it, we first make the 'inequality' sign to 'equal to' sign. This gives,
Now, we plot this line on a graph. The given line is of the form:
Where, 'm' is the slope and 'b' is the y-intercept.
So, for the line ,
The y-intercept is at (0, -3).
In order to draw the line correctly we find another point. Let the 'y' value be 0.
Now,
So, the point is (3, 0).
Now, we mark these points and draw a line passing through these two points.
Now, consider the line inequality . The 'y' value is less than
. So, the solution region will be region below the line and excluding all the points on the line. So, we draw a broken line and shade the region below it.
The graph is shown below.

Step-by-step explanation:
Given the differential model
We are required to solve the equation for P(t).
