Now use K C F method
K - Keep the first fraction
C - Change the division operation to multiplication
F- Flip the second number
Let's assume the frequency of sound be f and wave length is w.
Given that, the frequency of sound varies inversely as the wavelength.
So, we can set up an equation as following:
f*w = k Where k= constant of variation.
Other information is, the frequency of a musical note is 276 cycles per second when the wavelength is 1.2m.
So, next step is to plug in f = 276 and w = 1.2 in the above equation to get the value of k.
276 * 1.2 = k
So, k = 331.2
Next step is to plug in k = 331.2 in the above equation. So,
f * w = 331.2
Now we need to find the wave length : w when frequency : f = 600.
Therefore,
600 * w = 331.2
w = \frac{331.2}{600}
So, w = 0.552
Hence, the wave length is 0.552 m.
Hope this helps you!.

Answer:
- f(x²) = x² +5
- (f(x))² = x² +10x +25
Step-by-step explanation:
Put the argument in place of x and evaluate the desired expression.
__
1. f(x²) = x² + 5 . . . . . . straight substitution for x
__
2. (f(x))² = (x +5)²
= (x +5)(x +5) = x(x +5) +5(x +5) = x² +5x +5x +25
(f(x))² = x² +10x +25
Answer:

12. 32%
Step-by-step explanation:
First, you'll have to find how much it costs for one bottle of juice.
Store A- 4/12= 0.33 So one bottle of juice costs 33 cents.
Store B- 6/18= 0.33 So one bottle of juice costs 33 cents.
Yes, the rates are equivalent because one bottle of juice costs the same from each store.
