A closed box with square base is to have a volume of 6912 cubic inches. The material for the top and bottom of the box is to cost 4 cents per square inch and the material for the sides is to cost 1 cent per square inch. Find the dimensions of the box so that the total cost of material is least. If x is the length of the side of the square base and y is the depth of the box, then give your answer as (x,y).

Yesterday there was a group of about 50 Mexican Free-tailed Bats flying around the windows of my office on the 9th floor of an office building in San Antonio. I have seen Cave Swallows doing the same. I assume there are insects swarming around the windows, which explains the feeding behaviour of the bats and swallows, but I was very suprised to see this number of bats in the middle of the day.

Determine whether the graphs of the equations are perpendicular, parallel, or neither. How do you know?
1. y=6.4x + 8.9
5y-32x=5

2. 1/2x +3/4y =6
-3/2y + y=4

3. 2x + 6y= -3
12y=4x + 20
