Question

F(x)=440(2)^x/12 where x represents the the number of half-steps above or below A440.

Answer 1

Answer:

41.4%

Step-by-step explanation:

The formula for determining the frequency:   --A

where h is the number of half-steps from the A above middle C on the keyboard.

A note is six half-steps away from the A above middle C.

Now we are supposed to find How much greater is the frequency of the new note compared with the frequency of the A above middle C?

Now initially there is no half steps .

So, substitute h =0

Now we are given that A note is six half-steps away from the A above middle C

So, substitute h =6Now To find change percentage

               

             

             

Hence  the frequency of the new note is 41.4% greater with the frequency of the A above middle C.
