PLEASE HELP !! A researcher in North America discovers a spear head that contains 78% of its original amount of C-14.
N = Noe^-kt
No= initial amount of C-14 (at time t = 0)
N = amount of C-14 at time t
K = 0.0001
t = time, in years
Find the age of the bird skeleton to the nearest year.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

i believe the answers 600m

i can not answer the question due to the fact that you spelled "carton" as "cartoon", a cartoon is something you watch on tv, a carton is a box that holds things. and also you've been waiting for this question for a while so why don't you get off your lazy a** and try to figure it out for yourself for once!
