Answer:
50j
Step-by-step explanation:
workdone = force x distance
workdone = 20x2.5
50j
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
Answer:
the answer is x= 3 and y= -1
Answer:
Distributive property
Step-by-step explanation:
-3/4*5/4-(-6/7)*(-3/4)
-15/16-(18/28)
-15*7-18*4/112
-105-72/112
-177/112
