answer X= 5 over 7 and 2 over 7y step by step explaination add 2y on both sides u cancelled -2y and positive 2y u bring down 7X u get 7X=-5+3 then u divide and u get that answer yw have a nice day mark me brainliest
Answer:
0
Step-by-step explanation:
The first decimal place has the digit 0
the second decimal place has the digit 7
the third decimal place has the digit ....either 1 or 2.
this depends on the forth one, if it was 5 or higher, the third digit would be 2
since the fourth digit is 3, which is lower than 5, we don't have to change the third digit : it remains a "1"
so the answer is 0.071
9514 1404 393
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.
Answer:
Yes. It is an arithmetic sequence.
Step-by-step explanation:
The sequence would be add 5 every time.
-9 + 5 = -4
-4 + 5 = 1
1 + 5 = 6
