anonymous · Answer

this sounds like biology or something.

anonymous · Answer

it's math.

anonymous · Answer

Ok well maybe I just don't get it... What class is it for?

anonymous · Answer

algebra 2

anonymous · Answer

really? is there any other information with the problem?

anonymous · Answer

$$N = N _{0}e ^{-kt}$$

anonymous · Answer

N is amout remaining now; and No is initial amount?

anonymous · Answer

correct

anonymous · Answer

so, N =54, No =100 and what is k?

anonymous · Answer

54/100 = e^(-k *t)

log(.54) =-k *t
if u were given the value of k, just plug in and findout t.

anonymous · Answer

k = .0001

anonymous · Answer

plug in
log(.54) = -0.0001 * t
log(.54) / -0.0001  =  t

anonymous · Answer

i dont hav the calculator with me now, u have to feed it in and see what T is.

anonymous · Answer

log (.54) is a -ve value / - value of that k = +ve time...so thats right
