Anyla Scott was working out with the ropes next to Chantal and encouraged her to try to go faster. Chantal wanted to know which time she needed to have a speed of 4 ft/sec. If d = st then which equation can she use to the time she needs? d + s = t
d - s = t
s/d = t
d/s = t

The table respent two linear functions the equation respented by the first tables is given

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)
