The quantity and shut-down rules to build a supply function imply for a price-taking firm: That all all prices $S=MC$ regardless of any costs. That at every price below the average avoidable cost minimum $S=MC$. That sunk costs play a large role in deciding whether to shut down. That at every price above the average avoidable cost minimum, then firms will supply at $S=MC$.

3b. Derivation for maximum height above ground In this section you will derive an equation that gives the maximum height above the ground your projectile will reach. You will also include a table of the maximum heights for the three launch angles required. The formula for the maximum height, $\Delta y_{max}$, should be in terms of: \begin{itemize} \item horizontal distance to target, $\Delta x$ \item vertical height to target, $\Delta y$ \item launch angle, $\theta_0$ \item launch height, $h$ \end{itemize} As with the previous derivation, make sure this one is clearly laid out, showing all steps along the way and any explanations or assumptions made. Each cell in Table 4 represents the spring deformation, $\Delta d$, required for the given launch angle and horizontal distance. Table 4: Maximum height above ground Launch Angle, $\theta_0$ Calculations: 30° 45° 60° Horizontal Distance to Target, $\Delta x$ (m) 2 4 6 8 10
