(x) - 22-11-35353
[27-4 f x>3
( 3 f x<-3

[20-4 f x>3
d(x) - -x+2 of
5525-1

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

what is the original number? you forgot to add it.
