If all the ice on West Antarctica was melted, how much would it cause global sea level to rise? If you do not remember the approximate size of this rise, the volume of ice is $3,000,000 \mathrm{~km} 3$ and the surface area of the world's ocean is $361,000,000 \mathrm{~km} 2$.

A. less than 1 centimeter

B. 1 to 10 centimeters

C. 10 centimeters to 1 meter

D. 1 meter to 10 meters

E. more than 100 meters

Which feature on this diagram is a tarn?

A. 1, the circular depression at the head of the valley

B. 2, a lake in the upper valley

C. 3 , a steep ridge

D. 4, a valley that is above the level of the main valley

Escoge dos problemas del medio ambiente y presenta tus predicciones para cada uno. Usa expresiones como a menos que, con tal (de) que o hasta que.

Modelo:

El problema de la deforestación es muy grave. Hasta que todos los problemas protejan intensamente sus bosques, el calentamiento global va a continuar y muchos animales van a estar en peligro de extinción...

On a particular day, the linear function defined by

$$f(x)=-3.52 x+58.6$$

approximates the temperature in degrees Fahrenheit above the surface of Earth, where x is in thousands of feet and y is the temperature. (Source: Schwartz, Richard H., Mathematics and Global Survival, Ginn Press.)

(a) When the height is 5000 feet, what is the temperature? Solve analytically.

(b) When the temperature is $-15^{\circ} \mathrm{F}$, what is the height? Solve analytically.

(c) Explain how the answers in parts (a) and (b) can be supported graphically.

In an attempt to assess total daily travel taxes in various cities, the Global Business Travel Association conducted a study of daily travel taxes on lodging, rental car, and meals (GBTA Foundation website, October 30, 2012). The data contained in the DATA file named Travel Tax are consistent with the findings of that study for business travel to Chicago. Assume the population standard deviation is known to be $8.50 and develop a$95\%$ confidence interval of the population mean total daily travel taxes for Chicago.

Coordination of policy and the global economy: Think about a free market where the real exchange rate is constant and set at 1. Taxes, government spending, investment, and consumption are all determined by

$$C=10+0.8(Y-T), I=10, G=10, \text { and } T=10$$

Imports and exports are given by

$$I M=0.3 Y \text { and } X=0.3 Y^*$$

where Y* denotes foreign output. Why is it challenging to establish in practise fiscal coordination, such as the common growth in G and G* in the preceding part?

Consider the production of gold during the California gold rush (1848–1888). The production of gold can be modeled by $G(t)=\frac{(25 t)}{\left(t^{2}+16\right)},$ where t is the number of years since the rush began $(0 \leq t \leq 40)$ and G is ounces of gold produced (in millions). Find when the maximum (local and global) gold production occurred, and the amount of gold produced during that maximum.

What would happen to global sea levels if all the ice in West Antarctica melts?

A. it would not change because the volume of water you get from melting ice is only slightly more than the volume of the ice

B. it would not change because the volume of water you get from melting ice is only slightly less than the volume of the ice

C. sea level would fall because of isostatic rebound

D. sea level would rise by a significant amount

In 2015 Kraft Foods Group Inc., merged with H.J. Heinz Co. to form the world's fifth-largest food and beverage company. Heinz is a global brand, famous for its tomato ketchup, sauces, soups, beans, pasta and infant foods. Kraft is one of North America's largest consumer packaged food and beverage companies, with annual sales revenues of more than $\$ 18$ billion and over 22000 employees in the USA. Examine the possible reasons for the merger between Kraft and Heinz.

According to Global Research News (Mar. 4, 2014), one-fourth of all rough diamonds produced in the world are blood diamonds. (Any diamond that is mined in a war zone - often by children - in order to finance a warlord's activity, an insurgency, or an invading army's effort is considered a blood diamond.) Also, 90% of the world's rough diamonds are processed in Surat, India, and of these diamonds, one-third are blood diamonds. Find the probability that a rough diamond is processed in Surat and is a blood diamond.

Learn about Business Interview five adults to learn about their jobs and the companies that employ them. Ask questions about their job responsibilities to determine in which main function of business they work. Identify whether the companies that employ them are domestic or global in scope and if they are in the private or public sector. Identify their NAICS classification. Prepare a table using a word processing program to report your findings in an organized manner. Share your findings with classmates in an oral presentation.

A Ford Taurus driven $15,000$ miles a year will use about $715$ gallons of gasoline compared to a Ford Explorer that would use $940$ gallons. About $19.7 \mathrm{~lbm}$ of $\mathrm{CO}_{2}$, which causes global warming, is released to the atmosphere when a gallon of gasoline is burned. Find the extra amount of $\mathrm{CO}_{2}$ production a man is responsible for during a $5$-year period if he trades his Taurus for an Explorer.

A meteorologist preparing a talk about global warming compiled a list of weekly low temperatures (in degrees Fahrenheit) he observed at his southern Florida home last year. The coldest temperature for any week was

$$36 ^ { \circ } \mathrm { F }$$

, but he inadvertently recorded the Celsius value of

$$2 ^ { \circ }$$

. Assuming that he correctly listed all the other temperatures, explain how this error will affect these summary statistics: measures of center: mean and median.

Carbon dioxide $\mathrm{CO_2}$ is the gas that is mainly responsible for global warming (the greenhouse effect). The burning of fossil fuels is a major cause of the increased concentration of $\mathrm{CO_2}$ in the atmosphere. Carbon dioxide is also the end product of metabolism. Using glucose as an example of food, calculate the annual human production of $\mathrm{CO_2}$ in grams, assuming that each person consumes $5.0 X 10^2 g$ of glucose per day. The world's population is $7 .0$ billion, and there are $365$ days in a year.
