What is the best description of the technique of organizing a curriculum by using thematic units?
a. Structured drill and practice occurs for each mathematics content area before students are asked to solve real-world problems. *b. Problems in a unit are chosen not only to bring out important mathematics, but also to be relevant to a given real-world situation. c. Assessments are built into each unit so teachers can gather valuable information about students' understanding and determine the path future instruction should take. d. Students experience computer-assisted instruction that provides feedback about concepts with which they struggle
Solve the system.
A. x = 1, y = 4, z = 2 B. x = 4, y = 2, z = 1 C. x = 1, y = 2, z = 4 D. x = 4, y = 1, z = 2
Solve the problem.A projectile is fired from a height of 8.5 feet with an initial velocity of 158 ft/sec at an angle of 40° with the horizontal. The parametric equations for the path of the projectile are x = (158 cos 40°)t, and y = 8.5 + (158 sin 40°)t - 16t2,where x and y are in feet and t is in seconds. How long does it take the projectile to hit the ground? Round your answer to the nearest tenth of a second.
A. 6.3 seconds B. 6.4 seconds C. 12.9 seconds D. 8.2 seconds
