Answer:
- f = 4400/L
- 440 cycles per second
Step-by-step explanation:
When the variation is inverse, the product of values is a constant:
f·L = k = (400)(11) = 4400
f = 4400/L
Then a 10-inch string will vibrate with a frequency of ...
f = 4400/10 = 440 . . . cycles per second

Answer:
A
Step-by-step explanation:
let y = f(x) and rearrange making x the subject
Given
y = x - 2
Multiply through by 9
9y = x - 18 ( add 18 to both sides )
x = 9y + 18
Change y back into terms of x, hence
(x) = 9x + 18
