Quick answer Sin(570) = - 1/2
Comment
570 as an angle contains 1 complete revolution of the terminal arm. The terminal arm begins at the origin and the other (in this case swings around until it records 570° turning around the x axis in an anticlockwise direction.
Anticlockwise means going from 12 o'clock to 9 o'clock to 6 o'clock then 3 o'clock and back to 12 o'clock.
What is 570° (∅) degrees equivalent to?
We keep on subtracting 360 until we get a number between 0 and 360 inclusive.
Written this way 0 ≤∅≤360
570 - 360 = 210°
So we need to find the equivalent of 210°
Method
210° = 180° + 30°
This means that ∅ is 30° below the x axis in the 3rd quadrant.
Sin(30) = 1/2
In the third quadrant, the sine is minus. so
sin(210°) = - 1/2 <<<<<<< Answer
The answer is C
1/2(5x + 12)
because the perimeter is equal 20x + 6

The answer is 5!
Hope it helps!
So I'm guessing the answer is: any x from -6 to 6; any absolute value > 6 is not meaningful in this case because the x-axis represents the ground level, and no y values can be negative (underground). Range: y values from 0 (ground) up to 36 (an upward measure, in some kind of units). Drone flying upward is y = mx+b; choose m > 0 and b > 0 (e.g. m = 0.5, b = 24)--this will intersect the rainbow twice; you can find those points of intersection by setting the y values of line & parabola =, and solving the resulting quadratic equation by using the quadratic formula. x values of intersection are about -3.60 and 3.35.
