Which of the following is the correct expanded form for the series below?

The first one is correct

Step-by-step explanation:

simply plug in numbers from 0 to 4 in the position of n, which, in this case is -2^n.

the form comes out to:

-2^0, -2^1, -2^2, -2^3, -2^4

notice how the exponent does not include the negative, so it always remains negative. The one you selected would have been correct if it was (-2)^n

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
