VOCABULARY CHECK: Fill in the blanks. 1. An is the set of all points (x, y) in a plane, the sum of whose distances from two distinct fixed points, called . is constant. 2. The chord joining the vertices of an ellipse is called the , and its midpoint is the of the ellipse. 3. The chord perpendicular to the major axis at the center of the ellipse is called the of the ellipse. 4. The concept of is used to measure the ovalness of an ellipse.Identify the conic as a circle or an ellipse. Then find the center, radius, vertices, foci, and eccentricity of the conic (if applicable), and sketch its graph. * 2 7. 8. + =1 25 16 81 144 y 2 x2 V2 9. + = 10. + = 25 25 97 Question 7: Follow this format by copy and pasting then just change the values of your solved answers ... For example, Circle, C(0,0), r=5, V=n/a, F=n/a) and e=1. Please note that vertex and foci are n/a because the answer is circle. * (20 Points) Enter your answer 8 Question 8: Follow this format by copy and pasting then just change the values of your solved answers ...
