\[N = N _{0}e ^{-kt}\]

N is amout remaining now; and No is initial amount?
anonymous
  • anonymous
correct
anonymous

so, N =54, No =100 and what is k?
anonymous
  • anonymous
54/100 = e^(-k *t) log(.54) =-k *t if u were given the value of k, just plug in and findout t.
anonymous
  • anonymous
k = .0001
anonymous
  • anonymous
plug in log(.54) = -0.0001 * t log(.54) / -0.0001 = t
anonymous
  • anonymous
i dont hav the calculator with me now, u have to feed it in and see what T is.
anonymous
  • anonymous
log (.54) is a -ve value / - value of that k = +ve time...so thats right
