The sound intensity of rustling leaves, y = 20 decibels
<u>Step-by-step explanation:</u>
y = 10logx
The sound intensity of rustling leaves is 100 times the reference intensity.
x = ratio of intensity of sound to reference to intensity
x = 100:1 or x = 100
y = 10 log(100) = 10 * 2 = 20 decibels
y = 20 decibels

Step-by-step explanation:
A geometric sequence has a constant ratio 'r' and is defined by
where
Given the sequence
Compute the ratios of all the adjacent terms: 
The ratio of all the adjacent terms is the same and equal to
Therefore, the common ratio of the geometric sequence is:
Answer:
The answer is B
Step-by-step explanation:
on the left picture 5 * 5 = 25 sq ft
on the right picture, 5 * 2 - 10 sq ft
So the answer is B
