Answer:
we should know that :
sin ( a + b ) = sin a * cos b + sin b cos a
For the given equation :
sin (π + q) = sin π * cos q + sin q * cos π
sin π = zero and cos π = -1
∴ sin (π + q) = 0 * cos q + sin q * (-1) = - sin q
<u>Another solution:</u>
The angle (π + q) lies in the third quarter ⇒ (1)
(π + q) and (-q) are supplementary angles ⇒ (2)
From (1) and (2)
sin(π + q) = -sin q
Answer: E. Convenience
Step-by-step explanation:
- A convenience sampling is a method of sampling whose structure is based on accessibility to the researcher .
Given : An internet site asks its members to call in their opinion regarding their web searching habits.
Here the internet site is working according to its accessibility .
Hence, this is a type of convenience sampling .
Well, We have to Know What The Distance is to the Finish Line. product of is multiplication.
5 · 5 - 4 · 4 = 9 sorry if I'm wrong
the dots mean to multiply
