Answer:

  • D. f(q) = 2q + 3

Step-by-step explanation:

<u>Given equation:</u>

  • 6q = 3s - 9

<u>q is independent variable, we need to solve it for s:</u>

  • 6q = 3s - 9
  • 3s = 6q + 9
  • s = 2q + 3

<u>Correct choice is </u>

  • D. f(q) = 2q + 3

Remark

This will be a little late, but I'll answer it anyway. The more you see of the sine law, the clearer it will be.


Step One

Set up the sine Law.

\dfrac{Sin(x)}{12}=\dfrac{sin(75)}{22}


Step Two

Substitute values

Sin(x) = ??

sin(75) = 0.9659


\dfrac{Sin(x)}{12}=\dfrac{0.9659}{22}


Step Three

Cross multiply and Solve

22* Sin(x) = 12 * 0.9659

22* Sin(x) = 11.591 divide by 22

sin(x) = 11.591 / 22

sin(x) = 0.5269


Step Four

You have to know how to use the inverse of an angle to get the answer. I do it as my calculator would do it. If it doesn't work with yours, let me know.


x = sin^-1(0.5269)

2nd F

Sin^-1

(

0.5269

)

=

You should get 31.79 degrees.
