Step-by-step explanation:
so, that means we want to find the time t (days) after which N = No/2
because "half-life" means the amount of time until half of the substance has disappeared (or transformed into something else).
so, we have
No/2 = No × e^(-0.1481×t)
No = 2× No × e^(-0.1481×t)
1 = 2×e^(‐0.1481×t)
1/2 = 0.5 = e^(-0.1481×t)
ln(0.5) = -0.1481×t
t = ln(0.5)/-0.1481 = 4.680264555... ≈ 4.7 days
Answer:
try b
Step-by-step explanation:
Answer:
<h2>
0.67</h2>
Step-by-step explanation:
Distribute 5 through the parentheses
Distribute 4.7 through the parentheses
Move ' 4.7 y ' to L.H.S and change it's sign
Move constant to R.H.S and change it's sign
Collect like terms
Calculate
Divide both sides of the equation by 0.3
Calculate
Hope this helps...
