Answer:
n = 5.75
Step-by-step explanation:
original equation
n - 31/4 = 2
multiply everything by 4
n * 4 - 31/4 * 4 = 2 * 4
simplify
4n - 31 = 8
add 31 to both sides
4n - 31 + 31 = 8 + -31
simplify
4n = -23
divide both sides by 4
4n/4 = -23/4
simplify
n = 5.75
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:
D. Zero
Step-by-step explanation:
A solution is formed when the lines intersect at a
point. The coordinates will then be the solution.
In the diagram shown, the line and curve does not intersect at all so there is no solution to the curve.
