Correct question is;
What function is the inverse of the exponential function y = 1.5^(x)? 
Answer:
y = log_1.5_x
Step-by-step explanation:
The inverse of exponential functions is usually written in form of logarithm.
For example inverse of y = p^(x) will be written as; y = log_p_(x)
Similarly applying this same pattern to our exponential function y = 1.5^(x), we have the inverse as;
y = log_1.5_x
 
        
             
        
        
        
Answer:
5. You can round question a up to 100 + 55 (then do the counting)
5. You can round question b up to 245 - 100 (then do the counting)
You can round question c up to 100 x 5 (then do the counting)
You can round question d up to 100 x 20 (then subtract accordingly)

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.
