Answer:
A
Step-by-step explanation:
1/3 times 1/5 equals 1/15. That is already simplified :).
Answer:
The mode would be 45.
Step-by-step explanation:
The mode is 45 because a mode is the most repeated number in a set.
Answer:
d < 7/9
Step-by-step explanation:
Add 7d +10
7 > 9d
Divide by 9
7/9 > d
Answer:
A, C
Step-by-step explanation:
Actually, those questions require us to develop those equations to derive into trigonometrical equations so that we can unveil them or not. Doing it only two alternatives, the other ones will not result in Trigonometrical Identities.
Examining
A) True

Double angle 
B) False,
No further development towards a Trig Identity
C) True
Double Angle Sine Formula 

D) False No further development towards a Trig Identity
