B(-1,1),C(-1,3),D(-5,3), and E(-5,1) are the vertices of the preimage on the coordinate plane. B'(-1,-3),C'(-3,-3),D'(-3,-7), and E'(-1,-7) are the vertices of the after image on the same coordinate plane. Rectangle B'C'D'E' can be considered the rotation image of BCDE, the camera should be located at the center of rotation. Using only a compass and a straightedge, find the point where the camera should be located. Name this point A.

I am trying to explode a lit light bulb for a movie i am helping to make. the light bulb will be in full view, filling the frame, so i cannot have the bulb explode by hitting it with something, and i'd rather not drip water on it, which was my other idea.

A person lays out four cards on the table, each card has an alphabet on one side & a number on the other side of it. Now, he claims "if there is a vowel on one side, there is an even number on the other side". You want to test his claim, i.e. whether he is right or wrong, but he will only allow you to flip-over two cards. The four cards laid out are as follows:

A F 2 7

Which are the two cards you will flip over to test his claim?

Their is an arbitrary shuffle. Successive is as it implies: being dealt four cards in a row. Alternating means one down, and then one to you. If it eases results, we are referring to the first four cards to be dealt in the Successive dealing and the first 8 in Alternating. I've been pondering this question assuming a simple answer but I haven't reached a conclusion to date. If you are going to answer it for points please write something ridiculous to make me laugh. I'd prefer humor over the words "Succession" or "Alternation."
