Ksju [112]

Answer:

16.07 milligrams

Step-by-step explanation:

From the question,

Using the formula of radioactive decay,

R/R' = 2ᵃ/ᵇ..................... Equation 1

Where R = Original mass of the polonium-210, R' = Final mass of polonium-210 after decaying, a = Total disintegration time, b = half life of polonium-210.

Make R' the subject of the equation

R' = R/(2ᵃ/ᵇ)................ Equation 2

Given: R = 100 milligrams, a = 1 years = 365 days, b = 138.39 days

Substitute these values into equation 2

R' = 100/(2³⁶⁵⁰⁰/¹³⁸³⁹)

R' = 100/(6.222)

R' = 16.07 milligrams of plonium-210

Same as the one before a few way back.... so...check the picture below, then we use the pythagorean theorem

\bf (2s+9)^2=s^2+(2s+6)^2
\\\\\\
4s^2+36s+81=s^2+4s^2+24s+36\implies 36s+81=s^2+24s+36
\\\\\\
0=s^2-12s-45\implies 0=(s-15)(s+3)\implies 
\begin{cases}
0=s-15\\
\boxed{15=s}\\
-----\\
0=s+3\\
-3=s
\end{cases}
