Answer:
(8.49; 225°)
Step-by-step explanation:
The angle is a 3rd-quadrant angle. The reference angle will be ...
arctan(-6/-6) = 45°
In the 3rd quadrant, the angle is 45° +180° = 225°.
The magnitude of the vector to the point is its distance from the origin:
√((-6)² +(-6)²) = √(6²·2) = 6√2 ≈ 8.4859 ≈ 8.49
The polar coordinates can be written as (8.49; 225°).

<em>Additional comment</em>
My preferred form for the polar coordinates is 8.49∠225°. Most authors use some sort of notation with parentheses. If parentheses are used, I prefer a semicolon between the coordinate values so they don't get confused with an (x, y) ordered pair that uses a comma. You need to use the coordinate format that is consistent with your curriculum materials.
For this case we have that the commutative property establishes that the order of the factors does not alter the product. Example:
Then we have the following options illustrate the property:
It is necessary to emphasize that option b illustrates the associative property and in option c equality is not fulfilled

Answer:
The expected value of one draw is the average value of these 10 slips of paper which is:
24 / 10 = 2.4
Step-by-step explanation:
We have a bag with 10 slips of paper in it. 8 slips of paper each has a 2 on them; 2 slips of paper each has a 4 on them.
The total value of all the slips when added together is:
= (8)(2) + (2)(4)
= 16 + 8 = 24
The expected value of one draw is the average value of these 10 slips of paper which is:
24 / 10 = 2.4 ....
