Why do astronomers use astronomical units (AU) instead of kilometers (km)?(1 point) AU is used in astronomy, while km is used in physics.
There are no km in outer space, only AU.
Large distances are easier to express in AU than in km.
AU is used for spacing, while km is used for length.

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.

the titanic would be the correct answer

i think the answer is c hope this
