Answer:
See below.
Step-by-step explanation:
A.
n =1 , dots = 5.
n = 2, dots = 8.
n = 3, dots = 11.
n = 4, dots = 14.
B.
This is an arithmetic sequence.
C.
Yes.
D.
It is a function because for each input value it has one output value.
The nth term of the sequence = 5 + 3(n - 1).
Since order is important...
12!/(12-3)!=1320
or if you prefer
12*11*10=1320
Weight of copper = 1/2w and weight of zinc = 1/2 w
So:-
c = 0.5w*6 + 0.5w*3
c = 3w + 1.5w = 4.5w
this equation is the same as choice A
Answer:
B
