Answer:
The above result is proved with the help of Pythagoras theorem and explained below.
Step-by-step explanation:
Given figure ABCD in which AD=BC and all angles intersect at right angle. Hence, the triangle formed inside ADC and ABC are right angled triangle.
In triangle ADC,
By applying Pythagoras theorem, we get
→ (1)
In triangle ABC,
→ (2)
Now, from eq (1) and (2)
Peach Tree Dr. is the same distance as Sycamore Ln.
⇒ (∵ AD=BC)
⇒ DC=AB (∵Distance can never negative)
Therefore, Peach Tree Dr. is the same distance as Sycamore Ln.
Answer:
It will take 4.84 hours for the drug to decay to 93% of the original dosage.
Step-by-step explanation:
We are given that the half-life of a certain tranquilizer in the bloodstream is 47 hours.
The given exponential model is:
Now, we know that A becomes half after 47 hours which means that;
Using this in the above equation we get;
where t = 47 hours
Taking log on both sides we get;
k = -0.015
Now, the time it will take for the drug to decay to 93% of the original dosage is given by;
where t is the required time
Taking log on both sides we get;
t = 4.84 hours
Hence, it will take 4.84 hours for the drug to decay to 93% of the original dosage.
