2sin^2 θ + sin θ - 1 = 0
2sin^2 θ + 2sin θ - sin θ - 1 = 0
2sin θ(sin θ + 1) - 1(sin θ + 1) = 0
(2sin θ - 1)(sin θ + 1) = 0
2sin θ - 1 = 0 or sin θ + 1 = 0
sin θ = 1/2 or sin θ = -1
The two values of sin θ are 1/2 and -1
Answer12/0.5
Step-by-step explanation:
1. First, you multiply 147 x 10 which equals 1470. 2. Then, you add 1470 plus 3, which is 1473/10.
Answer:
y=2x
Step-by-step explanation:
If the line is parallel to 4x-2y=6, it means that it has the same slope. So let's first find the slope.
Rearranging, we get
-2y=-4x+6
2y=4x-6
y=2x-3.
So, the slope is 2.
Next, we can use the point slope formula
y-y_1=m(x-x_1)
Substituting, we get
y-2=2(x-1)
y-2=2x-2
y=2x
