Consider the following algorithm that finds a row where every entry is x in a 2-D array. Assume that (a) the array has n rows and m columns, and that (b) the comparison on line 3 counts towards the running time. 1 FOR every row in the array
2 FOR every column in the array
3 IF [row][column] == 'x' THEN
4 IF column is the last THEN
5 DISPLAY found row
6 ENDIF
7 ELSE
8 move on to the next row
9 ENDIF
10 ENDFOR
11 ENDFOR
1 What is the best case scenario?
2 What is the exact number of operations for the best case scenario in terms of n and m?
3 What is the big-oh for the best case scenario?
4 What is the worst case scenario?
5 What is the exact number of operations for the worst case scenario in terms of n and m?
6 What is the big-oh for the worst case scenario?

This first part of the film shows the early history of motion pictures. how accurate do you think the portrayal of the early motion picture industry is? why? is historical accuracy important in films and theatre productions? explain. in the scene where don is going to the party (starting at time code 14: 51), we see a street scene as he first rides with cosmo and then with kathy. what aspects did the filmmaker include to make the scene look and feel like don, cosmo, and kathy are riding in a car on a street? think about elements such as scenery, sound, props, lighting, and so on. a "talkie" picture is shown starting around time code 21: 15. how does the audience in the film react to the "talkie"? what influence do audiences have on film and theatre performances? how do film and theatre actors influence audiences? in the musical scene with cosmo (starting at time code 27: 00), how does the actor use props? what is the result? do you think the use of props effectively fulfilled the artistic vision for this musical number? why or why not?

Look at the far left lane in the picture. explain what the red car is doing and what it needs to do to travel safely.

If the polar bear were taken out of the food chain what would happen to the seal population the seal population would diminish the seal population would grow dramatically the seal population would stay the same the seal population would decrease slightly
