Answer:
hello : 
If f(x)=x-2 and g(x)=1/2x,
 g(f(x)) = g ( x - 2 )
           = 1/2(x-2)
g(f(x)) = (1/2)x - 1 
 
        
                    
             
        
        
        
Answer:
22.38 g of silicone-32 will be present in 300 years.
Step-by-step explanation:
A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay and its given by
                                            
where,
 = quantity of the substance remaining
 = quantity of the substance remaining
 = initial quantity of the substance
 = initial quantity of the substance
 = time elapsed
 = time elapsed
 = half life of the substance
 = half life of the substance
From the information given we know:
- The initial quantity of silicone-32 is 30 g.
- The time elapsed is 300 years.
- The half life of silicone-32 is 710 years.
So, to find the quantity of silicone-32 remaining we apply the above equation

22.38 g of silicone-32 will be present in 300 years.
