Answer:
Step-by-step explanation:
<u>For each odd i the term is:</u>
<u>For each even i the term is:</u>
So the sum of the first 100 terms is zero
They don't need to be pure real or imaginary. Any "mixed" complex number works so long as .
Let . Then
so .
The geometric interpretation is essentially identical. is a complex number twice the distance away from the origin in the complex plane as , which is exactly .
Answer:
A, y - 3 = -1/2(x + 1)
Step-by-step explanation:
To solve this problem, write each equation in the slope intercept form.
y - 3 = -1/2(x + 1)
Distributing -1/2 across each value in the parentheses, we get y - 3 = -1/2x - 1/2.
Adding 3 to both sides, we get y = -1/2x + 2 1/2.
Now that we have our equation, look at the graph. Is the equation correct? Yes, it is. The y-intercept is 2 1/2, and the slope is -1/2.
