WebJul 13, 2024 · To find how old the bone is, we first will need to find an equation for the decay of the carbon-14. We could either use a continuous or annual decay formula, but opt to use the continuous decay formula since it is more common in scientific texts. The half life tells us that after 5730 years, half the original substance remains. Solving for the ... WebNov 8, 2024 · ln( y y0) = − λt. Using the following property that related the exponential with the natural log: eln ( x) = x, and taking the exponential of each side of the equation and dropping the "prime", we get: y y0 = e − λt. Finally solving to y gives us the expression of how y changes as a function of time: y(t) = y0e − λt. WebNow we try to solve 100, 000 = 10 ⋅ eln200 4 t for t: divide both sides by the 10 and take logarithms, to get ln10, 000 = ln200 4 t Thus, t = 4ln10, 000 ln200 ≈ 6.953407835.
