Answer:
(3,20)
Step-by-step explanation:
hope this helps!
The value of p is (x22)(3x•21)
If you mean cuboid then no and if you mean rectangle but sides not faces then yes
To calculate what is asked we use the formula for radioactive decay. It is expressed as follows:
An = Ao (e^(-kt))
We calculate as follows:
An = Ao (e^(-kt))
74 = 100 (e^(-k(10)))
k = 0.0301
1/2 = (e^(-0.0301t))
t = 23 hours
Hope this answers the question.
