A unit circle is the one which has radius equal to 1.
The relation between radius of circle (r), the arc length (s) and the radian measure of angle made by arc (Ф) is given as:
s = rФ
For a unit circle, r = 1, so the above equation becomes:
s= Ф
This means, the arc length will be equal to the angle made by that arc in radians.
Answer: x ≤ 120
Step-by-step explanation: To get <em>x</em> by itself in this inequality, since it's being divided by -6, we must multiply both sides by -6, just like we would if we were solving an equation, but here is the trick you have to watch out for with inequalities.
When you multiply or divide both sides of an inequality by a
negative, you <u>must</u> switch the direction of the inequality sign.
So our second step in this problem reads x ≤ 120.
<u>Please give this idea your full attention.</u>
<em>Even the most advanced algebra students will sometimes forget to switch the direction of the inequality sign when multiplying or dividing both sides of an inequality by a negative.</em>

Answer: Causation
Explanation: One event is the result of another. In this case, several inches of rain causes the level of water in a lake to increase implying cause and effect.
