Once per week on weekend schedule when students focus on critical topics to score highly on SAT no-calculator and calculator math tests. Classes meet on Saturday or Sunday for 1.5 hours each day. These on-line classes are limited to 4-5 students each and use a proven format that ensures a dynamic, interactive learning environment. Each week focuses in-depth on a major math area tested on the SAT. The course begins with students’ taking a mock, timed full SAT math test that is reviewed thoroughly in the first class. After the first class test review, the following classes are organized into four key SAT areas- heart of algebra, data analysis, advanced mathematics, and selected high-frequency SAT math topics. Classes in each area give particular attention to word problems, a significant test emphasis of the SAT. The instructor with over 8 years tutoring SAT preparation coaches students in SAT test design and high-payoff test-taking strategies. The course concludes with a second mock, timed full SAT math test. The last class is a test review session that also identifies study plans and emphases to meet students’ individual needs.
A group of economists performed a study on the de-creasing population in a small town for a time period of 10 years. They determined that as a result of factors such as loss of jobs and a poor economy, the population of the town decreased by about 3.5% each year. Which of the following equations accurately describes the population of the town, P, in terms of its initial population, P0, and n, the number of years of the study?
A. P = P0(0.965)"
B. P = P0(0.965)n
C. P . P0(1.035)°
D. P = P 0(1 .035)n
Mount Asgard in Auyuittuq (pronounced- ow-you-eet-took) National Park, Baffin Island, Nunavut, was used in the opening scene for the James Bond movie The Spy Who Loved Me. A stuntman skis off the edge of the mountain, free-falls for several seconds, and then opens a parachute. The height, h, in meters, of the stuntman above the ground t seconds after he opens the parachute is represented by the equation h(t) = -10.5t+ 980. What does the 980 in the equation represent?
A. The speed of the stuntman
B. The height of the mountain
C. The height of the stuntman when he opens the parachute
D. The total length of time the stuntman is in the air
