My Notes OAsk Your Tea The radioactive isotope of lead, Pb-209, decays at a rate proportional to the amount present at time t an
Papessa [141]

Answer:

10.96 hours will take for 85% of the lead to decay.

Step-by-step explanation:

Suppose A represents the amount of Pb-209 at time t,

According to the question,

\frac{dA}{dt}\propto A

\implies \frac{dA}{dt}=kA

\int \frac{dA}{A}=\int kdt

ln|A|=kt+C_1

A=e^{kt+C_1}

A=e^{C_1} e^{kt}

\implies A=C e^{kt}

Let A_0 be the initial amount,

A_0=C e^{0} = C

\implies A=A_0 e^{kt}

Since, the half-life of 3.3 hours.

\implies \frac{A_0}{2}=A_0 e^{3.3k}\implies e^{3.3k}=0.5\implies k=-0.21004

\implies A=A_0 e^{-0.21004t}

Here, A_0=1\text{ gram}

A=(100-85)\% \text{ of }A_0=15\%\text{ of }A_0=0.15A_0

By substituting the values,

0.15A_0=A_0 e^{-0.21004t}

0.15=e^{-0.21004t}

\implies t\approx 10.96\text{ hour}

Answer: A). V = 1/3(3)(3)(5)

Step-by-step explanation:

• Use the volume of a pyramid formula: V = 1/3Bh, where h is height, V is volume, and B is the base area.

• The base area is length (l) • width (w), so use that to substitute B.

• Substitute the values to get the answer: A). V = 1/3(3)(3)(5)
