Vanessa is creating a design for a quilt that consists of right triangles that all have angles of 45 She is trying to determine the number of different triangles that she could make for this design What is true about the triangles that Vanessa is trying to create?

True or false? a circle could be circumscribed about the quadrilateral below.

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)

Tell whether the two rates form a proportion
