Question

5. The Earth revolves around the Sun along an ellipse. The Sun lies in the
focus of the ellipse. The largest distance from the Sun to the Earth is 152.1
million kilometers, and the shortest is 147.1 million kilometers. Find the
length of the semi-minor axis of the ellipse and the eccentricity of the el-
lipse. What is the distance between the two foci of the ellipse?​

Answer 1

Answer:

foci

Step-by-step explanation:

What is the distance between the two foci of the ellipse?

Remember the two patterns for an ellipse: Each ellipse has two foci (plural of focus) as shown in the picture here: As you can see, c is the distance from the center to a focus. We can find the value of c by using the formula c2 = a2 - b2.
