17. Determine the coordinates of the midpoint of the line segment whose endpoints are ACO, 2, 4) and B(-8, 2, -6). 18. Which does not represent a possible intersection of a line and a triangle? a. O points b. 1 point c. 2 points d. 3 points 19. Which does not represent a possible intersection of two spheres? a. O points b. 1 point c. 2 points d. infinitely many points 20. Which of the following has only one line of symmetry? c. isosceles triangle d. circle a. rhombus b. regular hexagon

Solution

Please post 1 question per post, as per forum rules.

So, Q17

The line segement has points = A(0,2,4) and B(-8,2,-6)

Therefore, the endpoints will have a midpoint as (0-8)/2 , (2+2)/2 , (4-6)/2 = (-4,2,-1)
So, this is the midpoint of the A and B cordinates( the line segment)
