Is there another part to this?
Answer:
a)
b) and c)
See explanation below
Step-by-step explanation:
a)
The combined resistance R is a function of the the two
parallel resistances
So
and we have
Similarly,
b)
If we divide both the numerator and denominator by 
in the expression for R, we get
hence, if we held 
constant and increase the fraction 
gets smaller and so does the denominator of R, as a consequence R gets larger.
When is very large, the denominator of R is close to 1, so R is close to
c)
By a symmetric reasoning, we see that R gets larger when holding constant and increases.
In this case, R gets closer to as grows.

Answer:
an = 13 -5(n -1)
Step-by-step explanation:
The "take away 5" rule means the common difference between terms is d=-5. For first term a1=13, the n-th term is ...
an = a1 +d(n -1)
an = 13 -5(n -1)
Answer:
What factors do the numbers 12 and 18 have in common?
O D. 1, 2, 3, 6
Step-by-step explanation:
12 = 1, 2, 3, 4, 6, 12
18 = 1, 2, 3, 6, 9, 18
factors do the numbers 12 and 18 have in common = 1, 2, 3, 6
The answer is 42.25!! hope it helps!!
