The augmented matrix of a linear system has been reduced by row operations to the form shown. continue the appropriate row operations and describe the solution set of the original system. 0 0 3 0 11 2 0 01 1 1 8 - 5 select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. o a. the solution set has exactly one element (type integers or simplified fractions.) o b. the solution set has infintely many elements. o c. the solution set is empty.

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.
