Prove the Intersecting Secants Theorem: Given a circle with chords AB and CD. if the lines AB and CD intersect at a point, E, that lies outside of the circle, as il- lustrated in Figure 10.30, prove that EA - EB = EC · ED. [Notice that, unlike the Intersecting Chords Theorem, here EA and EB are overlapping segments, as are EC and ED.] Figure 10.30. Exercise 10.4.4: Intersecting Secants Theorem (Hint: There are several...

Let R(A,B,C,D,E) be a relation with FDs F = {AB-C, CD-E, E-B, CE-A} Consider an instance of this relation that only contains the tuple (1, 1, 2, 2, 3). Which of the following tuples can be inserted into this relation without violating the FD's? (2 points) Select one: O (0, 1, 2, 4,3) (1,1,2,2,4) (1.2.2, 2, 3) o (1,1,3,2,3) All of the above can be inserted. None of the above can be inserted.
