The frequency, or pitch, of a musical note varies inversely with the wavelength. The speed of sound, 340.2 meters per second, is the constant of variation. An “A” note in octave 5, has a frequency of 880 Hertz. What is the wavelength of the sound made by the tuner in meters?

The wave length = 0.387 meters

Step-by-step explanation:

Remark

An inverse relationship is one of the variables is in the denominator of a fraction and the other is given on the other side of the equal sign. It sounds more complicated than it is. Here's that long sentence broken down to 3 letters.

f = k/w

Formula

f = k/w

f is the frequency

k is the speed of sound

w is the wavelength

Givens

f = 880 Hz

k = 340.2 m/s

w = ?

Solution

f = k/w

880 = 340.2/ w                   Multiply both sides by w

880*w = w* 340.2 /w

880*w = 340.2                    Divide by 880

w = 340.2/880

w = 0.387 m

answer: the correct one is a

step-by-step explanation:

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
