In 2025 we will have a zombie apocalypse that starts out with 3 people turning into zombies. If the population of zombies can be modeled by the formula z (t) = zo · 20.3+, what will the population of zombies be in 2035, 10 years later?

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 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)
