The university is scheduling cleaning crews for its ten buildings. Each crew has a different cost and is qualified to clean only certain buildings. There are eight possible crews to choose from in this case. The goal is to minimize costs while making sure that each building is cleaned. The management science department formulated the following linear programming model to help with the selection process.
Min 200x1 + 250x2 + 225x3+ 190x4 + 215x5 + 245x6 + 235x7 + 220x8
s. t. x1 + x2 + x5 + x7 ≥ 1 {Building A constraint}
x1 + x2 + x3 ≥ 1 {Building B constraint}
x6 + x8 ≥ 1 {Building C constraint}
x1 + x4 + x7≥ 1 {Building D constraint}
x2 + x7 ≥ 1 {Building E constraint}
x3 + x8 ≥ 1 {Building F constraint}
x2 + x5 + x7 ≥ 1 {Building G constraint}
x1 + x4 + x6 ≥ 1 {Building H constraint}
x1 + x6 + x8 ≥ 1 {Building I constraint}
x1 + x2 + x7 ≥ 1 {Building J constraint}
xj={1, if crew j is selected0, otherwisexj=1, if crew j is selected0, otherwise

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
