Question

Write the exponential equation with 2.7% decay rate and a starting value of (.25)

Put the answer HERE pls. thankyou

Answer 1

`f(x) = 0.25 ({0.973})^(x)`

Explanation:

`f(x) = a( {b})^(x) \\ a = initial \: amount \\ b = decay \: factor \\ b = 1 - r \\ r = decay \: rate \: as \: a \: decimal`

`2.7 * 100 = 0.027 \\ b = 1 - r \\b = 1 - 0.027 = 0.973`

`f(x) = a ({b})^(x) \\ a = 0.25 \\ f(x) = 0.25 ({0.973})^(x)`
