The sum of any geometric sequence, (technically any finite set is a sequence, series are infinite) can be expressed as:
s(n)=a(1-r^n)/(1-r), a=initial term, r=common ratio, n=term number
Here you are given a=10 and r=1/5 so your equation is:
s(n)=10(1-(1/5)^n)/(1-1/5) let's simplify this a bit:
s(n)=10(1-(1/5)^n)/(4/5)
s(n)=12.5(1-(1/5)^n) so the sum of the first 5 terms is:
s(5)=12.5(1-(1/5)^5)
s(5)=12.496
as an improper fraction:
(125/10)(3124/3125)
390500/31240
1775/142
Answer:
True.
Step-by-step explanation:
Volume of a cylinder = π r^2 h where h = height and π r^2 = the base area.
Volume / height = π r^2 h / h = π r^2 = base area.
it is proven congreunt ASA axiom
<m=<m(given)A
MN=MN(common side)s
<o=<o(given)A
24-28= 4
4/24=.16666666666
.1666666666x100 ≈ 16.67%
Answer:
-26
Step-by-step explanation:
Sum is the addition of two or more integers. The sum of negative and positive integers must always consider the sign before a number for the given numbers, we shall add them one by one as follows
-18+12=-6
-6+-27=-33
-33+-9=-42
-42+16=-26
Therefore, the sum is -26 which is not among the options given although this is the right answer
