When the iPad was introduced, Apple's constant marginal cost of producing this iPad was about \$220. Its fixed cost was \$2,000 million (= \$2 billion). We estimate that its inverse demand function was $P = 770 - 11Q$, where $Q$ is the millions of iPads purchased. a. What were Apple's average variable cost and average cost functions?

Consider crystalline nickel with its typical Fm3m (fcc) structure. Assume the origin of the cell is at the origin of three orthogonal axes with unit vectors \hat{a}, \hat{b}, \hat{c}. a. Draw the cell and give it an alternate set of rhombohedral cell parameters (from the origin to 3 nearest-neighbor lattice points). Draw those rhombohedral vectors \hat{a}, \hat{b}, \hat{c} on the cell and state expressions for them in terms of the lattice constant $a$ and the unit vectors. [+3] b. Derive expressions for the rhombohedral reciprocal lattice vectors \hat{a}^*, \hat{b}^*, \hat{c}^*. [+3] c. Draw the reciprocal lattice and label its 100, 010, and 001 lattice points. [+2] d. What Bravais lattice does the reciprocal cell have? [+2]
