andre has 45 sheets of paper and needs to buy more. a store has 5 reams of paper, and each ream contains 500 sheets of paper. the number of sheets of paper andre has after purchasing x reams is represented by a function.

f(x)=500x+45

what is the practical domain of the function?

all integers from 1 to 5, inclusive

all real numbers from 1 to 5, inclusive

{545, 1045, 1545, 2045, 2545}

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.
