Nrite an equation of the ellipse with foci at (3, 0) and co-vertices at (0, +_1).

Step-by-step explanation:

Equation of ellipse is

Where h,k is center

A is the length of semi-major axis. This axis include the foci

b is length of semi-minor axis. This axis includes main vertices.

Since we have 0,1 and 0,-1 as co-vertices, the length of the minor axis is 2 so the length of the semi-major is 1.

So we have now,

Next, to since the foci has a y coordinate of 0 and the co-vertrx has a x coordinate of 0, our center is 0,0

so we have

Now, we can do equation

B^2=1

C^2 is 9

S0, we now have

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.
