The diagram below shows alternating equilateral triangles and regular pentagons. If the pattern is continued, the heavy line shown will eventually form a complete regular polygon. How
many sides will this regular polygon have?

P. S the diagram is badly drawn, don’t come at me

Find the solution set of this inequality. enter your answer in interval notation using grouping symbols. |8x-4| ≤ 12

Which describes the difference between the graph of f(x)=x^2 and g(x)=-(x^2-2)

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)
