Answer:
1/5
Step-by-step explanation:
Reciprocal just means flipped you can put any whole number over 1 if it helps to see that
5/1 = 5
Since reciprocal is asking you to flip 5/1 meaning numerator becomes denominator and vice versa you end up with 1/5 being the reciprocal of 5
Sin 20° · sin 40° · sin 80° = 1/2 ( cos 20° - cos 60° ) · sin 80° =
= 1/2 ( cos 20° sin 80° - cos 60° sin 80° ) =
= 1/2 ( (sin 100° + sin 60°)/2 - 1/2 sin 80° )= ( sin 100° = sin 80° )
= 1/2 · ( 1/2 sin 60° ) = 1/4 sin 60° = √3 / 8
sin 60° = √ 3/2
√ 3 / 2 · √ 3 / 8 = 3/16 ( correct )
Answer:
Lol, thank you for telling me this information..
Answer:
-1/4
Step-by-step explanation:
Multiplying 64 by -1/4 results in -16;
mult. -16 by -1/4 results in 4,
and so on.
The common ratio is -1/4.
