Situation: Find the age of the spear head to the nearest
year.
An archaelogist in Turkey discovers a
spear head that contains 80% of its
original amount of C-14.
Enter the correct answer.
N = Noekt
DONE
OOO
No = inital amount of C-14 (at time
t = 0)
N = amount of C-14 at time t
k = 0.0001
t = time, in years

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

x = 3 ± √(5+y)
