Answer:
Step-by-step explanation:
We want to evaluate:
When x=0, we obtain the first term of the geometric series as
The common ratio of this geometric series is 
The sum of the first n-terms of a geometric series is
From x=0 to x=15, we have 16 terms.
The sum of the first 16 terms of the geometric series is
to the nearest tenth.
Answer:
40
Step-by-step explanation:
a+b=c
a=girls
b= boys
c= total
the statement tell us:
4/5 of a class is girls:
a=(4/5)*c
boys=b=8
c=a+b
so we have:
c=(4/5)*c + 8
c-(4/5)*c=8
(5c-4c)/5 = 8
c/5=8
c=8*5
c=40
total=40
(3^x-2)/9^x=1/3^x-2/9^x
which converges by thereom
it converges to 10/72=5/36
id show work if i could but take my word,
if u cant solve it try working out a few partial sums
Answer:
1:3
Step-by-step explanation:
Both numbers are divisible by 25:
∴ The simplified ratio is 1:3
Hope this helps!
