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 timet
K = 0.0001
t = time, in years
Find the age the bird skeleton to the nearest year

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
