Answer:
g = 33%
Step-by-step explanation:
To solve this;
The values in the ends of the rows are found by adding together the two previous cells.
Thus;
For the first row, we would add the value in cell AC to the value in AD to get the value in the corresponding column named "Total". This means we add 20% +g to get 53%;
Thus;
20% + g = 53%
Subtract 20% from each side to give;
g = 53% - 20%
g = 33%
Answer:
The amount of the supplement in Niklas' body immediately after the 12th dose is 4.30 micrograms.
Step-by-step explanation:
Half life is the time required for an element to decay into half of its initial size. The supplement has a half life of 4 hours means that it decay to half of its size every 4 hours. Therefore there are 6 stages of division in a day.
i.e ×

The amount of the supplement in Niklas' body after the first dose (first day) can be determined by;
= × 25
= 0.390625 micrograms
He used the supplement daily for 12 days (12th dose), but the amount of the supplement in his body immediately after the 12th dose would be;
amount in his body per day × number of period for complete decay
= 0.390625 × 11
= 4.296875
The amount of the supplement in Niklas' body immediately after the 12th dose is 4.30 micrograms. This is because immediately after the 12th dose, the supplement has not reach its half life.
