Four friends, a, b, c and d are standing varying distances away from a speaker which is producing sound waves. which person will most likely hear the loudest sound?

a) a

b) b

c) c

d)d

A ( a )

Step-by-step explanation:

The closer you are to a sound source ( speaker ) the louder the sound is but the farther you are the less likely you are to hear a sound this is because sound travels through the air and losses some of its content when it travels.

from the question it is noticed that the four friends stood at Varying distances starting from Friend A down to Friend D, and from the question description Friend A is the closest to the speaker and friend D is farthest from the speaker which is the sound source.

Friend D will most likely hear the least sound as long as he is the farthest frm the sound source.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
