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
1st one is x > 1
2nd one is x < -4
3rd one is x < 70
4th one is x > -2
6/7 already reduced to the lowest terms;
the numerator and the denominator have no common prime factors:
6 = 2 × 3;
7 is a prime number;
98/100 = (2 × 72)/(22 × 52) = ((2 × 72) ÷ 2)/((22 × 52) ÷ 2) = 49/50;
