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.
This is what we call a Fibonacci sequence:
Notice that after the 1,1:
4th term =3 ==> 2+1
5th term =5 ==>3+2
6th term =8==> 5+3
7th term = 13==> 8+5
8th term =...........13+8 =21
9th term = ...........21+13 =34
10t=h term =........34+21 = 55
In short each number equal the sum of the 2 preceding number
Answer:
n (aub)= n (a)+ n(b)
n (anb) = n (a)-n (b)
only a= n(a)+n(b) -(aub)
n only b= n (a)+n (b)-n (anb)
now solve your self because this formula help to solve
Answer: Yes 3/5 and 21/35 are equivalent.
Step-by-step explanation:
3 ÷ 5 = 0.6
21 ÷ 35 = 0.6
