QUESTION 17 Which of these has an elliptical orbit around the sun? Earth Jupiter Mars Earth, Jupiter, and Mars

earth

Explanation:

Earth moves around the Sun in an elliptical orbit. Earth's orbit is almost a perfect circle; its eccentricity is only 0.0167.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
