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:
![P=P_{0}*e^{-dt}](https://tex.z-dn.net/?f=P%3DP_%7B0%7D%2Ae%5E%7B-dt%7D)
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:
![P=10*e^{-0.00502*85}\\P= 6.5266 \mu g](https://tex.z-dn.net/?f=P%3D10%2Ae%5E%7B-0.00502%2A85%7D%5C%5CP%3D%206.5266%20%5Cmu%20g)
There will be 6.5266 micrograms of Polonium-210 in his body after 85 days.
*Note that 0.502% = 0.00502.

Answer:
![3\sqrt{3}](https://tex.z-dn.net/?f=3%5Csqrt%7B3%7D)
Step-by-step explanation:
This triangle is a 30°-60°-90° triangle, so you should always remember the rule shown in the picture. Because y is across from the 60° angle, it will be
. 3 is x because it is across from the 30° angle, so y will be
.
