Answer:
b
d
e
Step-by-step explanation:
the standar form is

so it's

only that
The points would be either:
-8 or 14
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

So, w = 0.552
Hence, the wave length is 0.552 m.
Hope this helps you!.
Answer: v=-18/5
Step-by-step explanation:
Assuming you want to solve for v, we need to use our algebraic properties.
[subtract both sides by 2]
[multiply both sides by 3]

Now, we know that v=-18/5.
I think 2,057.21 because 18,541.89 divided by 9 is 2,057.21
