The function Q(t)=Qoe^kt May be used to model radioactive decay. Q representing the quantity remaining after t years; k is the d
ecay constant. What is the decay constant for plutonium -240 if it's half-life is 6,300 years?
2 answers:
Answer:
A. -[ln(0.5)/6,300]
Step-by-step explanation:
Done on apex, it is correct.
Answer : The value of decay constant is, 
Explanation :
Half-life of plutonium-240 = 6300 years
The expression used to calculate the rate constant is:

where,
k = decay constant
= half-life
Now put all the given values in the above formula, we get:


Therefore, the value of decay constant is,

Answer:
28408
Step-by-step explanation:
212x134=28408
Trey will read 18 pages in 45 minutes.
This is because he read 2.5 pages a minute. 25/10 = 2.5
so if we 45/2.5 = 18
Your answer is 60 because you multiply 600 with .10 and get 60.00
