Answer:
0
Step-by-step explanation:
gradient is change in y coodinates devided by change in x coordinates which is (-2-8)÷(7-7) being that 7-7 is zero the whole value will be 0 to mean the slope is 0
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
-18 +15x = y

<span>17576000 because you can use 26 letters so you multiply that by 3 and get 18576 and then you multiply that by 1000 to get the answer</span>
