The formula for eccentricity, e, of an orbit is given below, where a is the length of the semi-major axis and b is the length of the major axis.

Solve the formula for eccentricity for the length of the semi-major axis.

The correct equation for the length of the semi-major axis is equation .

When the length of the major axis is 4 inches and the eccentricity of the orbit is , the length of the semi-major axis is inches (round to the nearest hundredth).

Part 1)

Part 2)

Step-by-step explanation:

The correct question in the attached figure

Part 1)

we have the formula

where

e the eccentricity

a is the length of the semi-major axis

b is the length of the major axis

solve for a

That means

Isolate the variable a

squared both sides

subtract 1 both sides

Multiply both sides by a^2

Divide both sides by (e^2-1)

Rewrite

square root both sides

simplify

Part 2) we have

Solve for a

substitute in the formula of part 1)

think about the doctor who treated the major and the speaker in the short story "in another country." put yourself in the shoes of the doctor, and based on what you read in the story, write what you think his thoughts about the major and the speaker would be. use the following vocabulary in your response and change the form of these words as needed: detached resign withered
