Answer:
A
Step-by-step explanation:
The picture below illustrates a hyperbola.
The intersecting plane does not pass through the vertex of a right circular cone (the vertex of the cone is the point where two nappes meet).
As you can see from the diagram, the plane intersects both nappes of a right circular cone.
Hence, correct option is option A: The plane does not pass through the vertex and intersects both nappes of a right circular cone.
For this case we have the following expression:
(x + 7) / (x ^ 2 - x - 2) = A / (x - 2) + B / (x + 1)
Rewriting we have:
(x + 7) / ((x-2) (x + 1)) = A / (x - 2) + B / (x + 1)
We multiply the equality by (x-2) (x + 1):
x + 7 = A (x + 1) + B (x - 2)
Rewriting we have the following system of equations:
A + B = 1
A - 2B = 7
Solving the system we have:
A = 3
B = -2
Answer:
constants A and B are:
A = 3
B = -2
