Derive the equation of the ellipse with foci at (1,0) and (−1,0) whose distance between vertices is 6. Make a picture to help. Label the foci, and place and label a point (x, y) along the ellipse. Draw the focal distances from the point (x, y) to each focus point.

Hint: Note that the endpoints on the major axis are often called vertices (the other endpoints on the minor axis are called co-vertices).

Use the fact that the distance between the vertices is equal to the sum of the focal distances. Use the distance formula to start.

30 points! here is a you are the new manager at trusty goods wholesale produce. you need to figure out how to adjust the amount of produce in your notes after the events of the day: you got 5 more crates of bananas someone returned 2 crates of apples a worker dropped a crate of grapes (oh no! , you had to throw them out) you sold a crate of bananas you sold 5 crates of apples can you write an expression to describe your day using: "a" for crates of apples "b" for crates of bananas and "g" for crates of grapes? make sure the expression is in simplest form question 2 (3 points) explain your steps using sentences.
