Exactly 8
To solve, either use long division or calculator
x + y = 6
relationship: x = 6 -y or y = 6-x
so answer: c. y = 6 - x
show work:
x + y = 6
subtract x to both sides
x + y -x = 6 -x
simplify
y = 6-x
Answer:
Step-by-step explanation:
The decay rate of a radioactive isotope (also called activity of the isotope) is given by:
where
r is the decay rate
k is the decay constant
N is the number of nuclei in the radioactive sample
The decay constant of a radioactive isotope is also related to the half-life of the isotope by the formula
where
is the half-life of the isotope, which is the time taken for the sample to halve, compared to its initial amount
In this problem, the half-life of plutioniun-239 is
Therefore, the k-factor (decay constant) is:
A'(-4, 3) i think is the answer
