Find all solutions in the interval [0, 2π) for 2 sin^2 x = sin x

Ede4ka [16]

Answer:

Step-by-step explanation:

2 sin²x=sin x

2 sin² x-sin x=0

sin x(2 sin x-1)=0

sin x=0

x=0,π

2 sin x-1=0

2 sin x=1

sin x=1/2= sin π/6,sin (π-π/6)

x=π/6,5π/6

-2(y+12)=y-9

lions [1.4K]

1) y= -5

2) m = -1

3) k = 3

4) y = -5

Step-by-step explanation:

1) $-2(y+12)=y-9$

Solving:

$-2(y+12)=y-9\\-2y-24=y-9\\Combining\,\,like\,\,terms:\\-2y-y=-9+24\\-3y=15\\y=15/-3\\y=-5$

2) $8(-1+m)+3 = 2 [m-5 1/2]\\$

Solving:

$8(-1+m)+3 = 2 [m-5 \frac{1}{2} ]\\-8+8m+3=2 [m-\frac{11}{2} ]\\8m-5=2 [\frac{2m-11}{2} ]\\8m-5=2m-11\\Combining\,\,like\,\,terms:\\8m-2m=-11+5\\6m=-6\\m=-6/6\\m=-1$

3) $8(12-k)=3(k+21)$ (Note: Considering 8(12-k)=3(k+21) instead of 8(12-k)=3(k=k+21))

Solving:

$8(12-k)=3(k+21)\\96-8k=3k+63\\Combining\,\,like\,\,terms:\\-8k-3k=63-96\\-11k= -33\\k=-33/-11\\k=3$

4) $2y-3(2y-3)+2=31$

Solving:

$2y-3(2y-3)+2=31\\2y-6y+9+2=31\\Combining\,\,like\,\,terms:\\2y-6y=31-9-2\\-4y=20\\y= 20/-4\\y = -5$
