Reasoning A linear function models the height of a burning candle. Candle A comes out of the mold at 202 mm, and is expected to be at 178 mm after 4 hours of burning. The model for Candle
B is h = 240 - 5t, where h is the height in millimeters and t is the time in hours. What are the initial
values for each candle? What do the initial values for each candle tell you?

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)
