Answer:
(3 7/8, -1 3/4)
Step-by-step explanation:
The midpoint is the average of the end point coordinates:
((5 1/2, -4 3/4) +(2 1/4, 1 1/4))/2
= (7 3/4, -3 1/2)/2 = (3 7/8, -1 3/4)
Distribute 6 thru the parenthesis=
198 pie plus 6 pie
Factor out the perfect square=
Pie 3 to the second power times 22 plus 7 pie 6
Calculate the square root =
3 pie 22 plus 7 pie 6
Which equals to 31.2177
The answer is choice D because if you combine the like terms, you get 15-23i
