An object is moving at constant speed around a horizontal circle of radius r. at a particular instant of time t1, the acceleration a1 = (−9.00î − 5.00k) m/s2, and at a later time t2, the acceleration a2 = (5.00î − 9.00k) m/s2. here, t1 = 5.00 s and t2 = 8.00 s. note that the path of the object is in the x-z plane. we use a coordinate system with the +x axis to the right, +z axis vertically down, and +y axis coming toward you.

(a) what is the period of rotation of the particle if it is moving in the clockwise direction?

(b) what is the period of rotation of the particle if it is moving in the counterclockwise direction?

(c) find the radius of the path for the two cases indicated in parts (a) and (b).

clockwise m; .

Is a deceasing linear model or an exponential decay model likely to be a better fit for the data about remembering? ?

Kerion has a beaded necklace business. she can make 12 necklaces is 2 hours. how long will it take her to make 9 necklaces?

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
