They are adding 16 to the number each time. So the next number in the sequence would be 78.
Step-by-step explanation:
d(1) = 14
d(n) = d (n-1) + 16
14 + 16 = 30
30 + 16 = 46
46 + 16 = 62
62 + 16 = 78 and so on...
Answer:
○ sin 15° = sin 30°⁄2 = ±√[1 - cos 30°\2]
Step-by-step explanation:
According to the Sine Half-Angle Identity, this is the formula:
sin x = sin ˣ⁄2 = ±√[1 - cos x\2]
Notice the <em>-</em><em>cos</em><em> </em><em>x</em><em>\</em><em>2</em><em> </em>inside the radical. The second option nearly resembles this option. It has a positive symbol inside. Do not let this confuse you. The Cosine Half-Angle Identity is the formula that has a positive in the radical:
cos x = cos ˣ⁄2 = ±√[1 + cos 30°\2]
