Given:
Initial mass, m₀ = 23 g
Decay constant, k = 0.13
Exponential decay obeys the equation

where t = time, days
For half life, the mass is m = m₀/2.
Therefore

Answer: The half life is 5.33 days

A. 36/42
Answer:
x = 34
Step-by-step explanation:
If it is bisected, that means the angles are equal <ABD = < CBD
The triangles are equal by SAS
That means AD = CD
2x+30 = 3x-4
subtract 2x from each side
2x+30 -2x = 3x-4 -2x
30 = x-4
Add 4 to each side
3x+4 = x-4+4
34 =x
