Final answer:
To determine the position of point C, we can use the midpoint formula. The position of point C is (-7.15, 6.5).
Step-by-step explanation:
To determine the position of point C, we can use the midpoint formula. The midpoint of two points (x1, y1) and (x2, y2) is given by:
(x1 + x2)/2, (y1 + y2)/2
Using the given points A(-7.3,3) and B(-7,10), we can calculate the midpoint:
(-7.3 + -7)/2, (3 + 10)/2 = (-14.3/2, 13/2)
Simplifying, we get (-7.15, 6.5)
Therefore, the position of point C is option (a) (-7.15, 6.5).
