2-63. Use your unit of measure to make a rectangle that has dimensions units by units.

What is the area of your rectangle? (That is, how many unit squares are there in your rectangle?)

When you answered part (a), did you count the squares? Did your team use a shortcut? If so, why does the shortcut work?

Compare your rectangle to rectangles that other teams made. What is the same about the rectangles and what is different?

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 0 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
