function
B.
not a function

Answers

Answer 1
Answer: A) A
B) A
C)A
D) B
Reason I know this is because if we look at the x number in all of these, if 2 are the same (like 2,6 and 2,4) then its a non function.
But if none of the x =the same value its a function.
Same goes for B
C 
and now D, is a non function because out X's:
3
5
5
7
5 was repeated so it's a nonfunction.
Got it?

(I also just took this test XD)

Sin 300° = 2 sin 150° cos 150° use exact values to show it is true​

Answers

Answer:

see explanation

Step-by-step explanation:

left side = sin300° = - sin60°  and sin60 = (√(3) )/(2), thus

sin300° = - (√(3) )/(2)

right side

sin150° = sin30° = (1)/(2) and

cos150° = - cos30° = - (√(3) )/(2), thus

2sin150°cos150°

= 2 × (1)/(2) × - (√(3) )/(2) = - (√(3) )/(2)

left side = right side ⇒ True
