3. The function $ f $ is defined on the closed interval $ [-2,8] $ and satisfies $ f(2)=1 $. The graph of $ f^{\prime} $, the derivative of $ f $, consists of two line segments and a semicricle, as shown in the figure below. (a) Does $ f $ have a relative minimum, a relative maximum, or neither at $ x=6 $ ? Give a reason for your answer.

Use the References to access important values if needed for this question. When Fe3O4(s) reacts with H2(g) to form Fe(s) and H2O(g), 36.1 kcal of energy are absorbed for each mole of Fe3O4(s) that reacts. Write a balanced equation for the reaction with an energy term in kcal as part of the equation. Use the SMALLEST INTEGER coefficients possible and put the energy term in an appropriate box. If a box is not needed, leave it blank.

*1.36 A problem was posed as follows: The equation for the velocity of a fluid stream measured with a Pitot tube is $v = \sqrt{\frac{2\Delta p}{\rho}}$ where $v$ = velocity $\Delta p$ = pressure drop $\rho$ = density of fluid If the pressure drop is 15 mm Hg, and the density of the fluid is 1.20 g/cm³, calculate the velocity in ft/s. The solution given was $\frac{2}{1} \left| 15 \text{ mmHg} \times \frac{1.013 \times 10^5 \text{ Pa}}{760 \text{ mm Hg}} \times \frac{1 \text{ N}}{1 \text{ Pa}} \times \frac{10^3 (\text{g})(\text{cm})}{(1 \text{ N})(\text{s}^2)} \times \frac{(\text{cm}^2)}{1.20 \text{ g}} \times \left( \frac{1 \text{ m}}{100 \text{ cm}} \right)^2 \right|$ $= \left[ 33322.4 \frac{\text{cm}^2}{\text{s}^2} \right]^{1/2} = 182.5 \frac{\text{cm}}{\text{s}}$ Check that the answer is correct by (a) Repeating the calculations but carrying them out in reverse order starting with the answer. (b) Consolidating the units and making sure the final set of units are correct.
