His small farm has been in his family for five generations and produces primarily the potatoes that have made Idaho famous for its agricultural capabilities. When Joel sells his potatoes to an agricultural wholesaler, market forces dictate that he accept the market rate for his crop. In other words, Joel cannot expect to receive a higher price for his potatoes that the market rate. What type of competition does Joel face in owning and operating his small potato farm?

2. The vertices of \(\triangle ABC\) are A(0, 3), B(2, 4), and C(1, 0). Translate \(\triangle ABC\) using the vector (-4, 3). Graph \(\triangle ABC\) and its image.
For a demonstration, a professor uses a razor blade to cut a thin slit in a piece of aluminum foil. When she shines a laser pointer ($\lambda$ = 680 nm) through the slit onto a screen 5.6 m away, a diffraction pattern appears. The bright band in the center of the pattern is 8.0 cm wide. Part A What is the width of the slit? Express your answer with the appropriate units.
1. (2 x 4=8 pts) Find each sum in a closed form. Allowed key strokes: power '^' a. $\sum_{k=1}^{n} (2k - 1)$ b. $\sum_{k=1}^{n} k^3$. Use the identity $(k + 1)^4 - k^4 = 4k^3 + 6k^2 + 4k + 1$ Find your answer as a polynomial that is not factored. c. $\sum_{k=1}^{n} k3^k$. Find the answer in the form of (..... polynomial in n.....) $3^n$ + ... constant .... similarly to Activity 2-2. Enter your answer completing the two missing parts. d. $\sum_{k=1}^{n} k^2 3^k$. Find the answer in the form of (.... polynomial in n ....) $3^n$ - .... constant .... Enter your answer completing the two missing parts.
(1) When the lattice constants of films and substrates are different, the coherent growth can only occur below a critical thickness. When films are thicker, dislocations will form at the interfaces (see figure below). Can you please explain the reason? (2) Your collaborator needs BaTiO$_3$ films that are under tensile strain. Based on the following figure, how would you choose the substrate? And please state the reason. (3) Can you please list two possible methods to change the oxygen octahedral rotations of perovskite oxides thin films?
