Hoowever after the toxic, effects of Dichloro on the evvironment began to appear, the chemical was banned in 1972. A common estimate for the half-life in the soil is 15 years. Write a decay law for Dichloro in the soil and use A for the initial concentration of Dicloro, and use t for the input variable

Answer 1

\[y=Ae ^{-\frac{\ln 2}{15}t}\]
is that not correct?

Answer 2

no i dont think so do u know if that is corecct

Answer 3

\[Ae^-In2/15^t\]

Answer 4

well i know that will yield 1/2A after 15 years, if thats what the question is asking

Answer 5

\[y=Ae^(In2/15^t)\]

Answer 6

um the exponent on the e is -ln(2)/15 times t

Answer 7

\[y=Ae^(-In2/15^t)\]
