Answer:
< - 52, 48 > and 70.77
Step-by-step explanation:
2v - 6u
= 2<- 11, 3 > - 6 < 5, - 7 >
= < - 22, 6 > - < 30, - 42 >
= < - 52, 48 >
| 2v - 6u | = =
= 70.77

Decay rate for Radium-228 is 0.01205
Step-by-step explanation:
The half life of radium-228 is 5.75 years. We need to find the decay rate for radium.
The formula used is:
Where N₀ = amount of radioactive particles at time = 0
N_t = amount of radioactive particles are time (t)
λ = rate of decay constant
t = time
We are given half life so, =0.5
t= 5.75 years
We need to find λ
Putting values in formula and solving:
So, Decay rate for Radium-228 is 0.01205.
