A radioactive substance decays exponentially: The mass at time t is m(t) = m(0)ekt, where m(0) is the initial mass and k is a ne
velikii [3]

Answer:

M = 1/0.000121 = 8264.5 years

Step-by-step explanation:

M = − k ∫∞₀ teᵏᵗdt

To obtain this mean life, we'll use integration by parts to integrate the function ∫ teᵏᵗdt

∫udv = uv - ∫ vdu

u = t

du/dt = 1

du = dt

∫ dv = ∫ eᵏᵗdt

v = eᵏᵗ/k

∫udv = ∫ teᵏᵗdt

uv = teᵏᵗ/k

∫ vdu = eᵏᵗ/k

∫ teᵏᵗdt = (teᵏᵗ/k) - ∫eᵏᵗ/k

But, ∫eᵏᵗ/k = (1/k) ∫eᵏᵗ = (1/k²) eᵏᵗ = eᵏᵗ/k²

∫ teᵏᵗdt = (teᵏᵗ/k) - eᵏᵗ/k²

The rest of the calculation is done on paper in the image attached to this question

The logarithmic expression ln(√e/y^3) can be rewritten as
kvv77 [185]

Answer:

\dfrac{1 - 6 \ln y}{2}

Step-by-step explanation:

\ln \dfrac{\sqrt{e}}{y^3} =

= \ln \dfrac{e^\frac{1}{2}}{y^3}

= \ln e^\frac{1}{2} - \ln y^3

= \dfrac{1}{2} \ln e - 3 \ln y

= \dfrac{1}{2} - 3 \ln y

= \dfrac{1 - 6 \ln y}{2}
