Jennifer took clothes to the cleaners three times last month. First, she brought 3 shirts and 1 pair of slacks and paid $9.96. Then she brought 6 shirts, 4 pairs of slacks, and 2 sports coats and paid $40.88. Finally, she brought 4 shirts and 2 sports coats and paid $20.94. How much was she charged for each shirt, each pair of slacks, and each sports coat? Jennifer was charged $ nothing for each shirt, $ nothing for each pair of slacks, and $ nothing for each sports coat.

A mass that weight 6lb stretches a spring 4in. The system is acted on by an external force 2sin(4sqrt(6)t)lb.If the mass is pulled down 3in and then released, determine the position of the mass at any time t. Use 32ft/s^2 as the acceleration due to gravity. Pay close attention to the units. Answer must be in inches

A building has a 9’ deep basement (foundation) wall that is 160’ long. The wall has no windows. On average, 8’ of the wall is below grade (underground). Assume an outside air temperature of 10°F, an inside temperature of 70°F, and an average ground temperature of 45°F.
a. Determined the rate of heat loss through the wall below grade if it is uninsulated.
b. Determine the rate of heat loss through the wall below grade if it is insulated with an R-value of about 12 hr*°F*ft2/Btu.
A commercial building is built on a slab on grade
foundation that is a 120’ by 48’ rectangular shape.
Assume the outside design temperature is -5°F. Determine the rate
of heat loss through the exterior
edge of a concrete slab.
a. For an uninsulated slab edge perimeter.
b. For a slab edge perimeter insulated with 1” of perimeter insulation (an R-value of about 2.5).
c. For a slab edge perimeter insulated with 2” of perimeter insulation (an R-value of about 5).

A mass weighing 19lb stretches a spring 8in. The mass is attached to a viscous damper with damping constant 4lb⋅s/ft. The mass is pushed upward, contracting the spring a distance of 2in, and then set into motion with a downward velocity of 7in/s. Determine the position u of the mass at any time t. Use 32ft/s2 as the acceleration due to gravity. Pay close attention to the units. Answer must be in inches

Suppose that f(t) is the unique solution to the IVP y' = t + y^2 , y(0) = 5 and g(t) is the unique solution to the IVP y' = 1/(y + t^2) , y(5) = 0.
a. Determine an IVP that the function y = f(g(t)) solves. [Hint: You differential equation part will contain the functions t, g(t), and y in its expression.
b. (2 points) Show that the function y = t also solves this IVP.
c. (2 points) Use the uniqueness part of the Existence & Uniqueness Theorem to conclude that f and g are inverses.
