how to write and solve for inequalities? Computer game starts with 100 points and loses points based on the following rules: pass a level and 8 points lost and catch a flower, 3 points are lost. Suppose Tina catches 6 flowers per level on average. Solve an inequality to determine the levels she must complete to have fewer than 20 points left. Tina must complete at least levels.

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)
