Solve.Wind resistance or atmospheric drag tends to slow down moving objects. Atmospheric drag varies jointly as an object's surface area A and velocity v. If a car traveling at a speed of 60 mph with a surface area of 36 ft2 experiences a drag of 345.6 N (Newtons), how fast must a car with 45 ft2 of surface area travel in order to experience a drag force of 460.8 N?
A. 64 mph
B. 61 mph
C. 66 mph
D. 69 mph
Answer: A

Solve the problem using matrices.In a study of heat transfer in a grid of wires, the temperature at an exterior node is maintained at a constant value (in °F) as shown in the figure. When the grid is in thermal equilibrium, the temperature at an interior node is the average of the temperatures at the four adjacent nodes. For instance
