A manufacturer of handcrafted wine racks has determined that the cost to produce x units per month is given by C = 0.3x² + 7,000. How fast is the cost per month changing when production is changing at the rate of 14 units per month and the production level is 80 units? Costs are increasing at the rate of $ (Round to the nearest dollar as needed.) per month at this production level.

dy Assume x and y are functions of t. Evaluate for 2xy -3x+2y³ = - 72, with the conditions dt dx dt = -8, x=2, y = -3. dy dt (Type an exact answer in simplified form.)

Consider the cones K = = {(x1, x2, x3) | € R³ : X3 ≥√√√2x² + 3x² M = = {(21,22,23) (x1, x2, x3) Є R³: x3 > + 2 3 Prove that M = K*. Hint: Adapt the proof from the lecture notes for finding the dual of the Lorentz cone. Alternatively, prove the formula (AL)* = (AT)-¹L*, for any cone LC R³ and any 3 × 3 nonsingular matrix A with real entries, where AL = {Ax = R³ : x € L}, and apply it to the 3-dimensional Lorentz cone with an appropriately chosen matrix A.

5.17 An aluminum curtain wall panel 12 feet high is attached to large concrete columns (top and bottom) when the temperature is 65°F. No provision is made for differen- tial thermal movement vertically. Because of insulation between them, the sun heats up the wall panel to 120°F but the column to only 80°F. Determine the consequent compressive stress in the curtain wall. CONCRETE COLUMNS CONNECTIONS Stress= ALUMINUM WALL PANEL 12'-0"
