Answer:
D
Step-by-step explanation:
f(x) = |x+3|=x+3 when x+3≥0 ⇒x≥-3
Answer:
x - 3 ≥ 1
Step-by-step explanation:
Solving each of the inequalities
x + 3 ≥ 1 ( subtract 3 from both sides )
x ≥ - 2
3x ≥ 1 ( divide each inequality by 3 )
x ≥ 
x - 3 ≥ 1 ( add 3 to both sides )
x ≥ 4 ← required solution
Hello! To find any number in the arithmetic sequence we can use a formula!
It is given by

The geometric sequence formula goes by

So for this we notice that there's a start of 5 and is being added 3 to get 8.
and then each time it is added by 2 more to get the next time
5
5+ 3 = 8
8 + 5 = 13
13 + 7 = 20
20 + 9 = 29
29 + 11 = 41
41 + 13 = 54
54 + 15 = 69
69 + 17 = 83
Your formula is

Where n starts at 2 not 1
POH is the -log [ OH- ]. Using this equation, simply find the -log of the OH- concentration to find the pOH:
pOH = - log ( 0.000086 ) = 4.07
