Hey there!
According to our customary units of miles, 1 mile is equal to 5,280 feet - and 3 feet is a yard. That means, we have to divide 5,280 by 3 to figure out how many yards are in a mile:
5280/3 = 1760
That means that one mile is 1760 yards. But we're not finished yet. It says 1/5 miles, not one mile. Therefore, we take one half of the total distance in yards of a mile and add it to that 1760, because it's 1.5, or 1-and-a-half. Which, in technical terms means "1-plus-a-half".
We have:
1760 + 1760/2 = 1760 + 880 = 2640
Therefore, 1/5 miles, since it's 2640 yards, is greater than the 2500 yards specified in the question.
Hope this helps!
That is where the line crosses the x axis or where y=0
set y=0
Bx=A
find x value
divie both sides by B
x=A/B
the x intercept is x=A/B
Answer:
The sound intensity of a whisper is 333.3 times the reference intensity
Step-by-step explanation:
Given : The function
gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity.
A whisper has a sound intensity of 30 decibels.
To find : Use your graph to help you complete the following statement. The sound intensity of a whisper is times the reference intensity.
Solution :
Graph is attached which shows their intersection at (1000,30).
We can also verify by substituting value.
We have given that a whisper has a sound intensity of 30 decibels.
Therefore, y=30 , Let log base 10

Logarithmic property 

The ratio of the intensity of the sound to a reference intensity is 1000 decibels
The sound intensity of a whisper is times the reference intensity is

The sound intensity of a whisper is 333.3 times the reference intensity.
If you edit the question or repost I can answer if you provide an image! :D
Answer:x=6
Step-by-step explanation:
So if y is 0, that’s 8(y) which is 0. That means the equation is 2x=12, which means x is 6
My comments don’t work! But it’s (6,0)
