If v(x, y) is the electric potential at a point (x, y) in the xy-plane, then the level curves of v are called equipotential curves because at all points on such a curve the electric potential is the same. sketch some equipotential curves if v(x, y) = c/ r2 − x2 − y2 , where c and r are positive constants.

3. solve by graphing: y = 2x + 6 x + y = -3

Question part points submissions used suppose that 100 lottery tickets are given out in sequence to the first 100 guests to arrive at a party. of these 100 tickets, only 12 are winning tickets. the generalized pigeonhole principle guarantees that there must be a streak of at least l losing tickets in a row. find l.

Need on this geometry question. explain how you did it.
