Anna deposited $10,000 into an account three years ago. the first year she earned 12 percent interest, the second year she earned 8 percent interest, and the third year she earned 4 percent interest. how much money does she have in her account today?

$12579.84

Step-by-step explanation:

Anna deposited $10,000 into an account three years ago.

The first year she earned 12 percent interest

Interest = 12% of 10000 =

Amount at the end of first year = 10000+1200 = 11200

The second year she earned 8 percent interest

Interest = 8% of 11200 =

Amount at the end of second year = 11200+896 = 12096

The third year she earned 4 percent interest.

Interest = 4% of 12096 =

Amount at the end of third year = 12096+483.84 = 12579.84

Hence she have $12579.84 in her account today

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
