Step-by-step explanation:

We have,

The frequency of note A is 880 Hz and the frequency of note D is 1175 Hz. It is required to find the ratio of D to A.

It means \dfrac{f_D}{f_A}.

Using the values of frequency of D and A. So,

\dfrac{f_D}{f_A}=\dfrac{1175}{880}

In decimal form,

\dfrac{f_D}{f_A}=1.33

In integer form,

\dfrac{f_D}{f_A}=\dfrac{1175 }{880}\\\\\dfrac{f_D}{f_A}=\dfrac{235}{176}

What is the value of n in the equation 0.2(n - 6) = 2.8?<br> (1) 8 (3) 20<br> (2) 2 (4) 44
Vera_Pavlovna [14]
So,

0.2(n - 6) = 2.8

Distribute.
0.2n - 1.2 = 2.8

Add 1.2 to both sides.
0.2n = 4

Divide both sides by .2.
n = 20

Check.
0.2(20 - 6) = 2.8

Simplify inside parentheses.
0.2(14) = 2.8

Multiply.
2.8 = 2.8 This checks.

S = {2.8}

State one form of the Law of Cosines and provide a trick for writing the other two forms and explain when Law of Cosines should
Yuki888 [10]

Solving for <em>Angles</em>

\displaystyle \frac{a^2 + b^2 - c^2}{2ab} = cos∠C \\ \frac{a^2 - b^2 + c^2}{2ac} = cos∠B \\ \frac{-a^2 + b^2 + c^2}{2bc} = cos∠A

* Do not forget to use the <em>inverse</em> function towards the end, or elce you will throw your answer off!

Solving for <em>Edges</em>

\displaystyle b^2 + a^2 - 2ba\:cos∠C = c^2 \\ c^2 + a^2 - 2ca\:cos∠B = b^2 \\ c^2 + b^2 - 2cb\:cos∠A = a^2

You would use this law under <em>two</em> conditions:

  • One angle and two edges defined, while trying to solve for the <em>third edge</em>
  • ALL three edges defined

* Just make sure to use the <em>inverse</em> function towards the end, or elce you will throw your answer off!

_____________________________________________

Now, JUST IN CASE, you would use the Law of Sines under <em>three</em> conditions:

  • Two angles and one edge defined, while trying to solve for the <em>second edge</em>
  • One angle and two edges defined, while trying to solve for the <em>second angle</em>
  • ALL three angles defined [<em>of which does not occur very often, but it all refers back to the first bullet</em>]

* I HIGHLY suggest you keep note of all of this significant information. You will need it going into the future.

I am delighted to assist you at any time.
