Math Problem Statement
Solution
To solve the problem of finding the number of points of intersection between the two graphs, let's analyze the equations provided:
-
Equation 1:
This represents a circle with center and radius (since ). -
Equation 2:
This represents an ellipse centered at , with a semi-major axis of (along the -axis) and a semi-minor axis of (along the -axis).
Step-by-Step Solution:
-
Location of the circle and ellipse centers:
- The circle's center is at .
- The ellipse's center is at .
- The vertical distance between the centers is .
-
Range of the shapes:
- The circle extends vertically from to .
- The ellipse extends vertically from to .
Clearly, the circle and the ellipse do not overlap vertically. The circle's highest point is at , and the ellipse's lowest point is at .
Conclusion:
The circle and the ellipse do not intersect, so the number of intersection points is 0.
Answer: F. 0
