This answer is true ceremonies help deals with loss
You didn't list the options
btw
the next step should be
(add 4 to both sides)
2y = 16
or
2y - 4 + 4 = 12 + 4
Sin(13π/8) , is in quadrant IV so the angle will be negative, find the reference angle.
<span>sin(13π/8) = -sin(16π/8 - 13π/8) = -sin(3π/8) = -cos(4π/8 - 3π/8) = - cos(π/8). </span>
<span>Use half angle formula for cos(x): </span>
<span>cos²(x/2) = (cos(x) + 1) / 2 </span>
<span>Let x = π/4 </span>
<span>cos²(π/8) = (cos(π/4) + 1) / 2 </span>
<span>cos²(π/8) = (√(2) / 2 + 1) / 2 </span>
<span>cos(π/8) = √(√(2) / 4 + 1/2) </span>
<span>-cos(π/8) = -√((√(2) + 2) / 4)</span>
Answer:
Domain: {1,2,4}
Step-by-step explanation:
The domain is the input values
We normally list the value in order from smallest to largest and only list the values one time if they appear more than once
Domain: {1,2,4}
