Sin⁻¹ √2 = 1/√2 = 1(√2) / (√2)(√2) = √2/2
C2+ 10
Twice = multiply by two
10 more than = add ten
Hope this helps!
Answer:
c=|x-7|
Step-by-step explanation:
Given:
set-up fee 5,500
variable fee 1 per CD.
Cost per CD is $5.50
5.50 - 1= 4.50
5,500 / 4.50 = 1,222 CDs Choice A.
1*1,222 = 1,222
1,222 + 5,500 = 6,722
6,722/1,222 = 5.50
Proof with explanation:
We know that the sum of first 'n' terms of a Geometric progression is given by

where
a = first term of G.P
r is the common ratio
'n' is the number of terms
Thus the sum of 'n' terms is

Now the sum of first '2n' terms is

Now the sum of terms from
to
term is 
Thus the ratio becomes
