Decoding the LaTeX that didn't render, we seek sum of the angles of the seventh roots of
That's on the unit circle, 45 degrees into the third quadrant, aka 225 degrees.
The seventh roots will all be separated by 360/7, around 51 degrees. The first seventh root has
That's around 32 degrees.
The next angle is
The next one is
and in general
The first sum is just -135° since it's one seventh of the sum of seven -135s.
We have 1+2+3+4+5+6+7 = (1+7)+(2+6)+(3+5) + 4 = 28 so
If I didn't screw it up, that means the answer is
Answer: 1305°
Okay so for Mike, he has $22 in his account.
He deposits $11.50 in it each week, and they want to know how much he has in 12 weeks.
First, multiply $11.50 * 12, which is $138. Then add the $22 that's already in the account, which brings him to $160.
Now for Tim,
He has $218 and withdraws $13 every week.
13 * 12 = 156
Now subtract 218 and 156
218 - 156 = 62
So at the end of 12 weeks, Mike has $160 dollars in his account, and Tim has $62 in his account.
The direction of the vector is - 21.8 N of E , Option B is the answer.
<h3>What is a Vector ?</h3>
A vector is an object with both magnitude and direction.
A vector is shown in the graph.
To determine the direction , The angle needs to be determined
The slope of the vector will give the direction of the vector
The vector starts from the point (1 , 1)
Another point on the vector (-4 , 3)
slope = -2 /5
It is making angle x with the line y = 1
tan x = -2 /5
x = - 21.8 N of E.
Therefore the direction of the vector is - 21.8 N of E , Option B is the answer.
