Answer:
Option D is correct.
Explicit formula for the geometric sequence is, 
Step-by-step explanation:
Geometric sequence states that a sequence of numbers in which the ratio between consecutive terms is constant,
we can write a formula for the nth geometric sequence in the form of:
.....[1] where 
is the first term and r is the common ratio between successive term.
Given the sequence: 64, 32, 16 , 8......
Here, first term () = 64.
Common ratio(r) = 0.5
Since,
,
......
Substitute the value of a and r in [1] we get;
therefore, the explicit formula for the geometric sequence is,
Answer:
6:16
Step-by-step explanation:
To find the answer you do 3x_=6 which the missing number is 2, so you do 8x2=16 because whatever you multiply the first number by you have to do the same to the second number in fractions, ratios, etc.
Answer:
2,144.66 miles³
Step-by-step explanation:
v = (4/3)πr³
v = (4/3)π(8³)
v = 2,144.6605848506
Rounded
2,144.66 miles³
The picture looks confusing.
You divide 10000 by 1/10 then times that by 2 which equals 200,000 then divide that by 1/8 which is 160,000 then by 1/2 and you get 3,200,000
To solve this problem, we are going to use trial and error.
If the 2 numbers are 3 and 4 then 3 and 4 is 12 and 3 + 4 = 7 which cannot be divided equally, so this is not the answer.
3 and 5 = 15 but this is not divisible by 2.
6 and 3 = 18 and 6 + 3 = 9 which is 1/2 of 18
therefore, one set is 6 and 3.
