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.
Answer:
The answer is 88 square inches. (A)
Step-by-step explanation:
The shape is broken up into 2 right triangle sand 2 rectangles.
The area of the triangle is 12. You subtract the way it is cut in half where the dashed line that sais (4 in.) so you take 7 - 4 = 3. Now that the 3 is left meaning it is the height of the triangle. and then the bashed line that says
(8 in.) is the base of the triangle. Multiply that and it is 24 but you have to divide by 2 which gives you 12. since there are "Identical" triangles what I do is add 12 which will give you 24 again bc of both triangles combined.
As for the rectangle is both dashed lines (4 in. And 8 in.) multiply it gives you 32, again since here is another "Identical" rectangle you add 32 + 32 = 64 (Both rectangles combined)
Lastly add 64 + 24 = 88
Answer:
-11
Step-by-step explanation:
Hello :3
To find your answer we need to subtract first because, a week is 7 days and it tells us he rented it for 10 days. So, 10-7=3, so d = 3.
Next, we need to multiply. So, $120 · 3 = $360.
Now time to add. $400 + $360 = $760.
So, it will cost $760 for a 10-day rental.
Hope This Helps!
