Suppose 1 0 1 A = 0 1 1 1 1 0 and 0 1 0 B = 0 1 1 1 0 0 Find the Boolean matrix product AB; also find the Boolean matrix product BA. Write both matrices on your paper, clearly labeling each. Examine the two matrices and determine which one of the following statements is false? Question 5 options: The last row of AB is 0, 1, 1; this is the same as the first row of BA. The second row of AB is 1, 1, 1; this is the same as the second row of BA. The last column of AB is 0, 1, 1; this is the same as the first column of BA. The second column of AB is 1, 1, 1; this is the same as the third column of BA. None of the above (each of a, b, c, and d is true)

Given two points A(x₁,y₁) and B(x₂,y₂), the midpoint "M" between A and B will be:
M((x₁+x₂)/2 , (y₁+y₂)/2)

Data: 
UV(5,-11)
U(3,5)
V(x₂,y₂)

Therefore:
(3+x₂)/2=5      ⇒x₂=5*2-3=10-3=7
(5+y₂)/2=-11   ⇒y₂=-11*2-5=-27

Hence:
V(7,-27)
