It’s b, square root of 3 is irrational, 2 is rational, it creates a irrational number
Given:
The geometric sequence is
To find:
The sum of first 8 terms of the given geometric sequence.
Solution:
We have,
Here, the first term is 4 and the common ratio is
The sum of first n terms of a geometric sequence is
Where, a is the first term and r is the common ratio.
Putting n=8, a=4 and r=-3, we get
Therefore, the sum of first 8 terms is -6560.
Answer:
x = 5.5
EF = 14
Step-by-step explanation:
We can use ratios to solve
AG 7
----------- = -----------------
EG 2x+3
We know that EG is 2 times AG since A is the midpoint
AG 7
----------- = -----------------
2 AG 2x+3
Canceling like terms
1 7
----------- = -----------------
2 2x+3
Using cross products
1 (2x+3) = 2*7
2x+3 = 14
Subtract 3 from each side
2x+3-3 = 14-3
2x =11
Divide by 2
x = 11/2
x = 5.5
EF = 2x+3 = 2*5.5+3 = 14
