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:
your y is 6.7
Step-by-step explanation:
In a parallelogram, opposite angles are equal and since it is a quadrilateral, the angles add up to 360°
<NKL = <LMN = X
<KLM = <KNM = 3X
So, 2(x+3x) = 360°
80x = 360°
x = 45°
The figure LFND is another quadrilateral where:
<LFN = <NDL =90°
<FND = 3x
So, (90×2)+3x+ (angle FLD) = 360°
Angle FLD = 360° - 180° - (3×45)°
= 360° - 315°
= 45°
