The black figure is an ellipse, and the black line segment is is major axis. what is the length of the blue line segment?

D

Step-by-step explanation:

The formula we need to solve this is:

Where

 is the distance from one focus to the vertex

 is the second distance from another focus to same vertex

Note: Here, vertex point is the point on top. The common point from which the RED and BLUE line meets the 2 foci

 is half the length of the major axis (which is 9 here since total major axis is given as 18)

Now we can plug into the equation and solve:

D is the correct answer.

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.

whew you’re speaking a different language
