The annual worldwide production of all grains is about $9 \times 10^{12} \mathrm{~kg}$. How much grain is produced per person if there are approximately $6 \times 10^9$ people in the world?

In this exercise, write a graph that matches story below. The Amount of snowfall is the y-axis and Time is the x-axis.

The snow fell more and more softly.

What are the four conditions needed for uninterrupted flow? Describe each.

Area A farmer plans to fence a rectangular pasture adjacent to a river (see figure). The pasture must contain $245,000$ square meters in order to provide enough grass for the herd. What dimensions will require the least amount of fencing if no fencing is needed along the river?

Electrolysis of a metal nitrate solution $\mathrm{M}\left(\mathrm{NO}_3\right)_2(a q)$ for $325 \mathrm{~min}$ with a constant current of $20.0 \mathrm{~A}$ gives $111 \mathrm{~g}$ of the metal. Identify the metal ion $\mathrm{M}^{2+}$.

The Joint Strike Fighter (JSF) program, operated by the U.S. Department of Defense, is a global defense program that involves the acquisition of military fighter jets for participating allied countries. An article in the Air & Space Power Journal (March-April 2014) reported the estimated annual cost of adding a military aircraft to the JSF program. The table below lists the year of initial operation and cost (in millions of dollars) for 12 JSF military aircraft models. For this problem, let $y=$ estimated annual cost and $x=$ year of initial operation for each aircraft model.

c. Provide an estimation of the increase in the cost of adding a military aircraft to the JSF program each year. (Hint: Practically interpret the slope of the line.)
