A segment XD is drawn in rectangle QUAD as shown below.
What are the measures of <XDQ and <UXD?
m<XDQ
m<UXD

Can someone check if i did this correct. it’s number 4 if you’re wondering.

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)
