3+1=4, 4+2=6, 6+3=9, 9+4=13, 13+5=18, 18+6=24, 24+7=31. Your answer is 31. Each time , the number you add by is increased by 1
If one were to put the y value into the equation, they could find out what x is for a certain value of y.
Putting in the value of y (1), we get the equation:
1=4x-1
2=4x
x=0.5
This means that the value of x when why is 1 is x=0.5
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]
