An explorer is caught in a whiteout (in which the snowfall is so thick that the ground cannot be distinguished from the sky) while returning to base camp. He was supposed to travel due north for 4.8 km, but when the snow clears, he discovers that he actually traveled 7.8 km at

A map of North Carolina is scaled so that 3 inches represents 93 miles, How far apart are Raleigh and Charlotte if they are 1.8 inches apart on the map?

Base your answers to question on the topographic maps and block diagrams of two landscape regions shown below.

The block diagrams show a threee-dimensional view of the topographic maps directly above them. Elevations are measured in feet. Points $A, B, C$, and $D$ are locations on Earth's surface.

A stream begins to flow downhill from point $D$ toward the depression. After a period of time, the depression fills with water. Overflowing water from the depression moves downhill toward point $C$.

Which topographic map shows the most likely resulting change in the contour lines?

Base your answers to question on the weather map provided below which shows partial weather station data for several cities in eastern North America.

The 20th term of an arithmetic sequence is 96 , and the common difference is 5 . Find the $n$th term.

A plane is 150 miles north of a radar station, and 30 minutes later it is $60^{\circ}$ east of north at a distance of 100 miles from the radar station. Assume the plane flies on a straight line and maintains constant altitude during this 30-minute period. a. Find the distance traveled during this 30-minute period. b. Determine the average velocity of the plane (relative to the ground) during this 30-minute period.

Exercise gives the first derivative of a continuous function y = f(x). Find y'' and then sketch the general shape of the graph of f. y' = x(x - 3)^2

An acquaintance brags that she will finance her college education with government-insured student loans and then go bankrupt after graduation to avoid paying them. Is this possible? Is this ethical?

C.S. was a healthy, active teenager, other than experiencing irregular menstrual cycles and severe dysmenorrhea (painful menstruation). She had gained weight during her college years. Family history indicated that a paternal great-grandmother had diabetes. Current history included two miscarriages at 3 months' gestation and one at 5 months after amniocentesis. At age 36, after a course of fertility drugs, C.S. became pregnant, but developed high blood pressure in the first trimester. Routine testing at 3 months' gestation revealed elevated blood glucose and protein in the urine as a result of gestational diabetes and kidney dysfunction. Insulin injections and daily oral ASA were prescribed, as well as weekly appointments with the obstetrician. A weight loss of 30 pounds occurred during the pregnancy. Using your knowledge of normal physiology, explain how glucose and protein can be present in the urine.

From the previous exercises determine how much more will a person with 4 yr of college who earns the median amount will make during his or her career than a person with no college attendance who earns the median amount during his or her career? If the expenses of a 4-yr college degree are estimated at $ 95,780, is earning a 4-yr college degree worth it?

Describe Berlin Airlift

Use the map above, the topic lessons, and other primary and secondary sources to create a written presentation about the Berlin airlift. In your presentation, use the map and text information to describe how Germany and Berlin were divided between West and East; why Stalin stopped all highway, railway, and waterway traffic from western Germany into West Berlin in June 1948; how the United States and Britain responded; and what the Berlin airlift demonstrated.
