Answer:
Step-by-step explanation:
Using the method of cross products, we solve for Q.
48/9 = 32/Q
48Q = 32 x 9
Q = 32 x 9/ 48
Q = 6

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:
Answer: Y = 7x/2 -2
Step-by-step explanation:
Y intercept of -2 means there's a point at (0,-2).
Given the two points (4,12) and (0,-2), we can now find the slope
12-(-2)/4-0 = 14/4 = 7/2 which is the slope
so the equation is Y = 7x/2 -2
