Answer: The level of the dose be after 3 hours= 0.03125 mg.
Step-by-step explanation:
General exponential decay equation : 
, where A = initial value , r= rate of decay , x =Time period.
Here, drug’s effectiveness is decreasing exponentially.
AS per given , we have
A= 250 mg
x=3
r= 95% = 0.95
Then, 
Hence, the level of the dose be after 3 hours = 0.03125 mg.

Answer:
A function is a relation in which each possible input value leads to exactly one output value. We say “the output is a function of the input.”
The input values make up the domain, and the output values make up the range.
Step-by-step explanation:
You round 92 to 90. Then you round 68 to 70. Now you know that 9x7 = 63. You add to zeros to that answer and get 6300. So 92x68 is about 6300. The actual answer of the problem 6256 that will round up to 6300
