A car is travelling on a straight stretch of roadway. And the speed of the car is increasing at a constant rate. At time 0 seconds, the speed of the car is v0 meters per second; 10 seconds later, the front bumper of the car has traveled 125 meters and the speed of the car is v10 meters per second.

In the table, select values of v0 and v10 that are together consistent with the information provided. Make only two selections, one in each column.

Experiment

Researchers conducted an experiment to determine how much cooler the air would be in and around a building with a highly reflective roof surface, as compared to the air in and around a building with a dark roof surface. The researchers constructed four identical small structures, with the exception that each structure had a different type of material for its roof. Each structure had a roof made of exactly one of the following four roofing materials: tin painted silver, tin painted white, black asphalt shingles, and asphalt shingles painted white. At a time when the outside air was 25°C, the following measurements were taken: roof surface temperature, air temperature six inches above the structure, and air temperature inside the structure.

The researchers hypothesized that, for each category, the structure with the white asphalt shingles would have the lowest temperatures, the structure with the white tin would have the second lowest temperatures, the structure with the black asphalt shingles would have the highest temperature, and the structure with the silver tin would have the second highest temperatures.

ResultsThe graphic shows the temperature measurements, to the nearest degree, that the researchers took for each of the four roofing types.

At XYZ Inc., an employee receives a verbal warning upon accumulating at least 3 unexcused absences within any 365-day period and a written reprimand upon accumulating at least 4 such absences. For any single 8-hour workday, missing between 10 minutes and 2 hours of work counts as one-third of an absence, missing between 2 hours and 4 hours of work counts as half an absence, and missing more than 4 hours counts as a full absence. However, an employee may stay late to make up for up to 1 hour of an unexcused absence on the same day.

The table contains descriptions of the unexcused absences of 5 employees of XYZ Inc. Assume that in each case the employee had no other unexcused absences and made up no other time. In the table, select a description of an employee who qualified for a verbal warning but not a written reprimand, and select a description of an employee who qualified for a written reprimand. Make only two selections, one in each column.

Verbal warning Written reprimand
Absent all day on 5 April 2010,8 June 2010, 17 April 2011, and 14 June 2011
Absent 4.5 hours but stayed 1 hour late on 13 May 2010; absent all day on 2 June 2010, 1 May 2011,and 21 July 2011
Absent 4.5 hours on 19 March 2010; stayed 1 hour late on 20 March 2010;absent all day on 8 February 2011 and 9 February 2011; arrived 40 minutes late on 17 April 2011
Absent 3.5 hours on 13 September 2010; absent 1 hour on 15 September 2010;absent 6 hours on 16 September 2010;absent 2.5 hours on 18 September 2010;absent 1 hour on 19 September2010

Metro Ballet Company presents high-quality productions of traditional, classical ballet. For the past several years, however, the company's overall profits have been declining, and ticket sales have been flat. Annual audience surveys indicate that a majority of those who attend Metro Ballet productions consistently enjoy the performances and prefer classical ballet to other forms of dance; almost all of them have been attending Metro Ballet for several years. General surveys of area residents indicate, however, that very few are aware of

Metro Ballet productions, and most imagine that the performances are boring and the tickets too expensive. In an effort to appeal to a wider audience, over the past decade the company has spent increasing amounts of money on spectacular stage productions, while lowering ticket prices.

In the first column of the table, select the strategy that, in the absence of the other alternatives listed, would lead most directly to decreasing Metro Ballet's expenses for its classical ballet productions. In the second column, select the strategy that, in the absence of the other alternatives listed, would constitute the most direct approach to solving the problem of in creasing audience size for Metro Ballet's classical ballet productions. Make only two selections, one in each column.

Decrease expenses Increase audience size
Obtain public funding to double the spending on stage productions without increasing ticket prices
Return spending on productions to levels of several years ago
Expand productions to include modern, folk, and tap dance traditions
Offer special discounts to reward people who have attended the greatest number of performances
Mount a local advertising campaign emphasizing the affordability and excitement of Metro Ballet's spectacular stage productions

Miguel's online banking password is nine characters long and includes at least one character of each of five types: digits, punctuation marks, uppercase (capital) letters, lowercase (noncapital) letters, and certain other characters. The password begins or ends with one of these other characters, of which it contains exactly one. No consecutive characters in the password are of the same one of these types. (For example, no capital letter is preceded or followed by another capital letter.) The password contains more lowercase letters than characters of any one of the other four types. It also contains fewer punctuation marks than digits, lowercase letters, or uppercase letters. The first three characters of the password are M, ?, and G.

In the table, select a type of character that the fifth character in the password must be and a type of character that the seventh character must be. Make only two selections, one in each column.

Fifth Character Seventh Character
Digit
Lowercase letter
Punctuation
Uppercase letter
Other character
