Step-by-step explanation:
4(2)² - 4 =
4(4) - 4 = 12
3(2)² - 3(4)
3(4) - 12
12 - 12 = 0.
It exceeds the value by 12 :)
Given:
are in geometric sequences.
To find:
The value of x.
Solution:
If a, b, c are in geometric sequences, then
...(i)
It is given that are in geometric sequences. By using (i), we get
On further simplification, we get
Therefore, the value of x is 0.
Answer:
470:80
Step-by-step explanation:
75 is rounded to 80, while 470 stays the same because it doesn't need to be rounded.
Answer:
Assuming the repetitive part is 152, i.e. the original repeating decimal is
A=3.152152152....
then
1000A=3152.152152152152....
subtract A
1000A-A=3152.152152....-3.152152152....
999A=3149
A=3149/999=3+152/999=3 152/999
Therefore
3.152152152.... = 3149/999 or 3 152/999
