3. A typical 3-D printer creates objects by laying down layers of ink one on top of another.The average thickness of a layer depends on the caliber of the printer. For one particular3-D printer, the average thickness of a layer is 102 μm (micrometers). When creatinga 1-inch cube, the printer takes 6 seconds to lay down each layer of ink. Approximatelyhow long should it take this printer to create a 1-inch cube? (There are 1,000,000micrometers in a meter, and 1 inch is approximately equal to 0.0254 meters.)

• A. 12 minutes
• B. 25 minutes
• C. 40 minutes
• D. 1 hour, 6 minutes

12. Sea ice extent is a measurement of the area of ocean with at least 15% sea ice. Thegraph below shows data for the extent of Arctic sea ice between 2000 and 2012 as reportedby the National Snow and Ice Data Center. The line of best fit is also shown. Theequation of the line is A(t) = -0.187t + 380.5, where A(t) represents the area of measurable sea ice in the Arctic Ocean in the year t.

Based on the equation of the line of best fit, which of the following statements accuratelydescribes the change in the amount of measurable Arctic sea ice during the given timeperiod?

• A. The amount of sea ice increased approximately 187,000 square kilometers per year.
• B. The amount of sea ice increased approximately 187 million square kilometers per year.
• C. The amount of sea ice decreased approximately 187,000 square kilometers per year.
• D. The amount of sea ice decreased approximately 187 million square kilometers per year.

13. Sea ice extent is a measurement of the area of ocean with at least 15% sea ice. Thegraph below shows data for the extent of Arctic sea ice between 2000 and 2012 as reportedby the National Snow and Ice Data Center. The line of best fit is also shown. Theequation of the line is A(t) = -0.187t + 380.5, where A(t) represents the area of measurable sea ice in the Arctic Ocean in the year t.

Assuming the trend of the data continues, in what year will the measurable sea icein the Arctic Ocean cease to exist?

• A. 2026
