This is a fairly easy half-life problem
Each half-life reduces the radioactive material by one half.
So after 72 hours the radioactive material would have undergone 6 half-lives.
2^6 = 64.
So, there will be one sixty-fourth of the material left.
520 / 64 = 8.125 grams will remain.
radioactive decay is an exponential decay function.

Answer: 196pi in.^2
Step-by-step explanation:
Divide the diameter by two.
You would get 14, then square it, you would get 196.
X = -3, y = 2 rise over run
Answer:
p = - 9
Step-by-step explanation:
Given
- 1 + 5p = - 10 + 4p ( subtract 4p from both sides )
- 1 + p = - 10 ( add 1 to both sides )
p = - 9
