Answer is:
6162 years
Explanation:
The given equation to use is:
<span>N=Noe^-kt
First, we will need to define the variables of the equation as follows:
No : original amount of C-14 (at t=0)
N : amount of C-14 at certain time (t)
k : a constant equals </span><span>0.0001
t : the time in years
Now, we are given that:
The skeleton contains 54% of it's original amount of C-14. This means that:
N/No = 54% = 0.54
Substitute with this given in the equation given, we will find that the only unknown is the time (t). We can now solve for t as follows:
</span><span>N=Noe^-kt
This can be rewritten as:
N/No = </span>e^-kt
Now,
N/No = e^-kt
0.54 = e^(-0.0001t)
Take ln for both sides:
ln (0.54) = -0.0001t
-0.61618 = -0.0001t
t = 6161.86 years which is approximately 6162 years

Answer:
4.81 x 10^13
Step-by-step explanation:
Just count how many numbers there are and subtract it by one for the exponent, and put the decimal behind the first number.
Answer:
49.81
Step-by-step explanation:
the formula I used is distance=
Lets say we are finding the distance from c to y
c=(-6,9)
y=(5,9)
cy=
cy=
cy=
cy=
cy=11
And you can find the distance between y and i, i and d, d and o, o and c, using the same formula.
After solving the distance of all I got
yi=16.55294536
id=1
do=9.219544457
oc=12.04159458
After you add them all up you get 49.8140844 which rounded to the nearest hundredth is 48.81.
Thank you and I hope that is helpful.
