you have to multiply by -3
so the answers are going to be one negative one positive
and the next 5th terms are 108,-324,972,-2916,8748
The unit rate is 2.5 pounds a week.
15/6 = 2.5
I hope this helps.
The correct answer would be the 2nd option because it increases by a specific amount every X value.
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
= initial quantity of the substance
= time elapsed
= 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.
