Given:
The function is:

Where p(t) represents the number of milligrams of the substance and t represents the time.
To find:
The correct explanation for the number 0.25 and 500 in the given function.
Solution:
The general exponential function is:
...(i)
Where, a is the initial value and b is the growth/decay factor. If
, then decay factor and if
, then growth factor.
We have,
...(ii)
On comparing (i) and (ii), we get
, it means initial there are 500 milligrams of the substance.
, this value is less than 1, it means the substance is decreasing by a factor of 0.25.
Therefore, 0.25 means the substance is decreasing by a factor of 0.25 and 500 means the initial value of substance is 500 milligram.
Answer:
8.4 (42/5)
well you know that 1/4 as a decimal is .25 so take the 5 and put it in front of the .25, so you will have 5.25. And 5/8 as a decimal is .625. then just divide them by using long division or a calculator.
I belive that the answer my be c but how they worded it made my probablitity calculations a bit harder.
Step-by-step explanation:

(5-2)^2+(5-2)^2=
