Select 4 of the 5 graph choices and fill in numbers/ values for generic equations, replacing variables as necessary, to create actual equations that can be graphed.
~ note ~
* a should never equal 0
* h and k can’t both be 0
* b, c and d can’t all be 0
* can’t duplicate any values

Determine whether the quadrilateral below is a parallelogram. justify/explain your answer (this means back it up! give specific information that supports your decision. writing just "yes" or "no" will result in no credit.)

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)
