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:
y = -2x + 12
Step-by-step explanation:
Parallel = Same Slope Perpendicular = Opposite Reciprocal of Slope
How to find "b" or y intercept:
y = mx + b (3,6) slope = m: -2
plug in the corresponding values for the variables
6 = -2(3) + b
12 = b
2x-12=4
put the 12 in place of y since they equal each other
2x=16
add 12 to both sides
x=8
divide both sides by 2
I'm assuming you wrote the question correctly so v = u*a*t
This means to find t just divide by its times:
t = v / (u*a)
