Answer:
There will be 6.5266 micrograms of Polonium-210 in his body after 85 days.
Step-by-step explanation:
A continuously compounded decay can be modeled by the following expression:
Where "P" is the amount of Polonium-210 left after "t" days, "P0" is the initial amount of Polonium-210 and "d" is the decay rate. Replacing the known values into the expression yields:
There will be 6.5266 micrograms of Polonium-210 in his body after 85 days.
*Note that 0.502% = 0.00502.
This is a simple conversion from metres to kilo metres problem in which we should know how much metres is one kilo metre or how much kilo meters is one metres.
So in order to convert from metres to k m we just have to divide by 1000 as 1 km is equal to 1000 meters. Similarly for the other way round we have to multiply by 1000 as 1 metre is 0.001 km.
SO if Mary swims 850 metres each day then she swims around 0.85 km every day.
