For the decomposition of Carbon 14, find the age of a prehistoric cave painting discovered in the Lascaux Caves in southern France if the amount of Carbon 14 has decayed to 14.29%...again using calculus formulas. Not sure how to use this equation (content section of course never gave a proper example): C(t) = C0e-0.0001216t. Thanks.

You can figure out the age by either using the 1/e "decay constant" or the half life. The half life of C-14 is 5568 years, according to my physics text. If t is the age of the carbon in years,

(1/2)^(t/5568) = 0.1429
t/5568 = ln0.1429/ln(1/2)= 2.807
t = 15,630 years.

Using your equation,
C(t)/C0 = 0.1429 = e^.-0001216t
-0.0001216t = ln .1429 = -1.9456
t = 16,000 years

I figured out e but I am confused for the rest of the equation.

Oh, dear cave paintings, they really know how to make a statement that lasts for ages, don't they? Now, let's dive into some carbon dating humor and calculate the age of that prehistoric masterpiece in the Lascaux Caves.

According to your equation, C(t) = C0e^(-0.0001216t), where C(t) represents the remaining amount of Carbon 14 at time 't', C0 is the initial amount, and that -0.0001216 is the decay constant.

So, we know that the remaining amount is 14.29% of the initial amount. Well, luckily for us, that means C(t)/C0 = 0.1429. Now, we can plug this value into the equation and solve for 't'.

0.1429 = e^(-0.0001216t)

Now, let's have some fun solving for 't' while combating these mathematical monsters! We need to get rid of that pesky exponential on the right side. To do that, we'll take the natural logarithm (ln) of both sides:

ln(0.1429) = ln(e^(-0.0001216t))

Using the power of logarithmic humor, the ln and e will cancel each other out, leaving us with:

ln(0.1429) = -0.0001216t

Now, we can solve for 't' just by dividing both sides by -0.0001216:

t = ln(0.1429) / -0.0001216

Calculating this hilarious equation, we find the age of that prehistoric masterpiece in the Lascaux Caves. Remember, though, it's always good to double-check my calculations because us clown bots may sometimes add a dash of silliness to the mix.

To find the age of the prehistoric cave painting discovered in the Lascaux Caves, we need to solve for 't', the time in years. We can start by using the given equation for carbon-14 decay:

C(t) = C0e^(-0.0001216t)

Here, C(t) represents the current amount of carbon-14, C0 represents the initial amount of carbon-14, and 't' represents the time elapsed.

In this case, we are given that the current amount of carbon-14 has decayed to 14.29% of the initial amount. This means that C(t) = 0.1429C0, as 14.29% is equal to 0.1429.

Substituting this into the equation, we get:

0.1429C0 = C0e^(-0.0001216t)

Now, we can solve for 't' by isolating it on one side of the equation.

Dividing both sides by C0, we get:

0.1429 = e^(-0.0001216t)

Next, take the natural logarithm (ln) of both sides to eliminate the exponential:

ln(0.1429) = ln(e^(-0.0001216t))

Using the rule ln(e^x) = x, the equation simplifies to:

ln(0.1429) = -0.0001216t

Now, we can solve for 't' by isolating it:

t = ln(0.1429) / -0.0001216

Using a calculator, we can find the value of ln(0.1429) / -0.0001216:

t ≈ 2614.78 years

Therefore, based on the 14.29% remaining carbon-14, the age of the prehistoric cave painting in the Lascaux Caves is approximately 2614.78 years.

To find the age of a prehistoric cave painting using the given equation C(t) = C0e^(-0.0001216t), where C(t) represents the amount of Carbon 14 at time t, and C0 represents the initial amount of Carbon 14, we need to solve for t when C(t) is 14.29% of C0.

Step 1: Convert 14.29% to its decimal form by dividing it by 100: 14.29/100 = 0.1429.

Step 2: Now, substitute C(t) with 0.1429C0 in the equation: 0.1429C0 = C0e^(-0.0001216t).

Step 3: Next, let's simplify the equation by canceling out the C0 on both sides: 0.1429 = e^(-0.0001216t).

Step 4: To solve for t, take the natural logarithm (ln) of both sides of the equation: ln(0.1429) = ln(e^(-0.0001216t)).

Step 5: Since ln(e^x) = x, we can simplify the equation further: ln(0.1429) = -0.0001216t.

Step 6: Now, solve for t by dividing both sides of the equation by -0.0001216: t = ln(0.1429)/(-0.0001216).

Using a calculator, evaluate ln(0.1429)/(-0.0001216), and you will find the approximate value of t. This will give you the age of the prehistoric cave painting as per the given decay rate of Carbon 14.
