the amount of radioactive isotope decays in half every year. the amount of isotope can be modeled f(x)=346(1/2)^x and f(1)=173.
what does the 346 represent?

Answer with explanation:
Decay Formula is given by:


R=Rate at which radioactive isotope is decaying.
t=Time Constant
Now, Coming to the Question ,
The Rate at which radioactive isotope is decaying is given by the formula:
![f(x)=346\times[\frac{1}{2}]^x \\\\f(1)=346 \times \frac{1}{2}\\\\f(1)=173\\\\f(0)=346\times[\frac{1}{2}]^0\\\\f(0)=346 \times 1=346](https://tex.z-dn.net/?f=f%28x%29%3D346%5Ctimes%5B%5Cfrac%7B1%7D%7B2%7D%5D%5Ex%20%5C%5C%5C%5Cf%281%29%3D346%20%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%5C%5C%5C%5Cf%281%29%3D173%5C%5C%5C%5Cf%280%29%3D346%5Ctimes%5B%5Cfrac%7B1%7D%7B2%7D%5D%5E0%5C%5C%5C%5Cf%280%29%3D346%20%5Ctimes%201%3D346)
⇒346= Initial Amount of Radioactive Isotope
The 346 is the original mass of the radioactive isotope.
