Answer:
The mass of the radioactive sample after 40 minutes is 12.8 g.
Step-by-step explanation:
The mass of the sample can be found by using the exponential decay equation:
Where:
N(t): is the amount of the sample at time t =?
N₀: is the initial quantity of the sample = 120 g
t = 40 min
λ: is the decay constant = 0.056 min⁻¹
Hence, the mass of the sample after 40 min is:
Therefore, the mass of the radioactive sample after 40 minutes is 12.8 g.
I hope it helps you!
Answer:
D. y ≥ 2x – 2
Step-by-step explanation:
Graph the inequality by finding the boundary line, then shading the appropriate area.
y ≥ 2 x + 2
Graph the inequality by finding the boundary line, then shading the appropriate area.
y ≥ − 2 x + 2
Graph the inequality by finding the boundary line, then shading the appropriate area.
y ≤ 2 x − 2
Graph the inequality by finding the boundary line, then shading the appropriate area.
y ≥ 2 x − 2
