Answer:
see explanation
Step-by-step explanation:
A geometric progression has a common ratio r between consecutive terms
That is each term in the sequence is obtained by multiplying the previous term by r
Consider 4, 8, 16, 32
4 × 2 = 8
8 × 2 = 16
16 × 2 = 32
This is a geometric progression with r = 2
Consider 3, 6, 9, 12
3 × 2 = 6
6 × 2 = 12 ≠ 9
This is not a geometric progression
Consider 2, 6, 18, 54
2 × 3 = 6
6 × 3 = 18
18 × 3 = 54
This is a geometric progression with r = 3
Consider 1, 5, 12, 125
1 × 5 = 5
5 × 5 = 25 ≠ 12
This is not a geometric progression

Step-by-step explanation:
<u>Given inequality</u>
<u>We can put this as</u>
We know the given exponential function has positive range y > 0
And the linear inequality covers the space above the line
This is all matching the last graph that is attached
The answer to the above eqaution is 1
Step-by-step explanation:
Proceeding step by step
Step 1= 1/(1-xᵃ⁻ᵇ)+ 1/(1-xᵇ⁻ᵃ)
on rearranging the equation (b-a) as -(a-b) and substituting the value
Step 2= 1/(1-x ᵃ⁻ᵇ) + 1/(1-x -⁽ᵃ⁻ᵇ⁾ )
Using the indices corrolary that 1/1- x ⁻ᵃ= -xᵃ/ (1- x ᵃ) and subsituting the value of the expression in the step mentioned below
Step 3=1/(1+x ᵃ⁻ᵇ) - (x ᵃ⁻ᵇ)/(1-x ᵃ⁻ᵇ)
Since the denominators are the same the two fractions can be added with common denominator being 1+x ᵃ⁻ᵇ
On adding the above mentioned step 3 we get
Step 4=(1- x ᵃ⁻ᵇ) / (1- x ᵃ⁻ᵇ)
=1
Thus the value of equation =1
