2,3,5,9,17 what’s the pattern?

The pattern is multiply by 2 then subtract 1

2 x 2 - 1 = 4 - 1 = 3

3 x 2 - 1 = 6 - 1 = 5

5 x 2 - 1 = 10 - 1 = 9

9 x 2 - 1 = 18 - 1 = 17

17 x 2 - 1 = 34 - 1 = 33

33 x 2 - 1 = 66 - 1 = 65

65 x 2 - 1 = 130 - 1 = 129

If the point (x,square root 3/2) is on the unit circle, what. is x?

galina1969 [7]

Answer:

$x=\pm\frac{1}{2}$

Step-by-step explanation:

On a unit circle, $(x,y)=(\cos\theta,\sin\theta)$ , so $\sin\theta=\frac{\sqrt{3}}{2}$ in this case. If you look at the attached circle, the only time that the y-coordinate is $\frac{\sqrt{3}}{2}$ is when $x=-\frac{1}{2}$ and $x=\frac{1}{2}$ , which correspond to angles of $\theta=\frac{2\pi}{3}$ and $\theta=\frac{\pi}{3}$ respectively
