The frequency of a note on the piano, in Hz, is related to its position on the keyboard by the function f (n) =440•2^ n/12 = where n is the number of keys (both white and black) above or below the note concert A. (Concert A, with a frequency of 440 hertz, is the frequency of the A key above the middle C key on a piano.) Using this function f(n), find the position n (relative to the position of concert A) of the piano key that has a frequency of 55 Hz. (In other words, what number n do you need to input in the function f (n) for f(n) = 55?) Show your steps and explain your solution process,

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
