Particle P moves along the y-axis so that its position at time t is given by y(t)=4t−23 for all times t. A second particle, particle Q, moves along the x-axis so that its position at time t is given by x(t)=sin(πt)2−t for all times t≠2. As time t approaches 2, what is the limit of the position of particle Q ? Show the work that leads to your answer.

Which term best describes the association between variables a and b? no association a negative linear association a positive linear association a nonlinear association a scatterplot with an x axis labeled, variable a from zero to ten in increments of two and the y axis labeled, variable b from zero to one hundred forty in increments of twenty with fifteen points in a positive trend.
