Answer:
The half-life in days is 6.3 days
Step-by-step explanation:
Here, we want to get the half-life
From what we have in the question, we can see that we have a first order decay relation
For a first order decay relation;
t1/2 = ln 2/k
That will be;
t1/2 = ln2/0.1095
t1/2 = 6.33
To the nearest tenth, this is 6.3 days
Answer:
Step-by-step explanation:
x -4 , 3x-11 , 5x - 18 ,.......
first term = a = x -4
Common difference (d) = second term - first term
= 3x -11 - [ x - 4]
= 3x - 11 - x + 4
= 3x - x - 11 + 4
= 2x - 7
nth term = a + (n-1)*d
12th term = x - 4 + 11*(2x - 7)
= x - 4 + 11*2x - 7 *11
= x - 4 + 22x - 77
=x + 22x - 4 - 77
= 23x - 81
Answer:
14/9
Step-by-step explanation:
(1+1/3)^2−2/9
=(4/3)^2-2/9
=16/9-2/9
=14/9
Break it up. 6 x 100, 6 x 90, 6 x 8. 600+540+48 = 1188.
