Solve for x. Non-calc

• $\frac{\pi}{6}$

• $\frac{2\pi}{3}$

• $\frac{\pi}{3},\ \frac{4\pi}{3}$

• $\frac{\pi}{6},\ \frac{2\pi}{3}$

Solve part b (non-calc)

• 0

•  $\frac{\pi}{2}$  

•  $-\pi$  

•  $\frac{3\pi}{2}$  

Non-calc

• y = sin(2x) + 1

• y = 2sin(x) + 1

• y = sin(x/2) + 1

• y = sin(x) + 2

Non - calc

• $T=7.15\sin\left(\frac{\pi}{6}\left(t-9.5\right)\right)+34.65$

• $T=7.15\sin\left(\frac{\pi}{12}\left(t-9.5\right)\right)+34.65$

• $T=7.15\sin\left(\frac{\pi}{12}\left(t+9.5\right)\right)+34.65$

• $T=7.5\sin\left(\frac{\pi}{12}\left(t-9.5\right)\right)+34.65$

Calculator

• a) C = 36.08 b) AB = 17.9

• a) C = 36.08 b) AB = 10

• a) C = 144 b) AB = 17.9

• a) C = 144 b) AB = 10

Solve part b. Non-Calculator

• r = 10

• r = 15

• r = 2.5

• r = 5
