The figure shows triangle pqr and line segment ab, which is parallel to qr:
triangle pqr has a point a on side pq and point b on side pr. the line ab is parallel to the line qr.

part a: is triangle pqr similar to triangle pab? explain using what you know about triangle similarity. (5 points)

part b: which line segment on triangle pab corresponds to line segment qr? explain your answer. (3 points)

part c: which angle on triangle pab corresponds to angle q? explain your answer. (2 points)

(i need on b. i already know a and c)

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
