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
Answer:
375
Step-by-step explanation:
500-125(25% of 500)=375
Answer:
sorrry im no good at math but maybe u can use khan academy
Step-by-step explanation:
For this case we have that by definition, the equation of the line of the point-slope form is given by:
Where:
m: It's the slope
It is a point through which the line passes
According to the given statement we have:
Substituting we have:
Finally, the equation is:
Answer:
The answer is -16
Step by step explanation:
the expression of this equation is √4x=-32, so first, we would find the square root of 4, which is 2. so now we have 2x=-32. Next we want to divide 2 from both sides, which gives us our final result: x=-16. So our answer is -16.
