It takes 16,064 years for the 500g of radium to decay to 5g.
<h3>
How long will it take for 500g of radium to decay to 5g?</h3>
Here we have the decay equation:
Where Q₀ is the initial amount, and k is the decay constant.
We know that:
Q₀ = 500g
k = 0.00043
And we want to find the value of t such that Q(t) = 5g, so we need to solve:
Now we can apply the natural logarithm in both sides:
So it takes 16,064 years for the 500g of radium to decay to 5g.

Answer: 20 cm
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain a variable.
Domain [-∞,+∞]
range [-∞,+∞] (f(-∞)=+∞, f(0-0)=0, f(0+0)=3, f(∞)= -∞)
f(-4)=16
f(0)=0
f(3)=-5
