Acar bought for $13000 depreciates at 129% annually. What is its value after 2 years? Do not include the dollar sign in your anSwer. Round your answer to the
nearest cent.

9,103.69

Step-by-step explanation:

y = A(d)^x

y = 12000(1-0.129)^2

Decay y = 12000(0.871)^2

solve for y = $ 9,103.69

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
