Felipe transferred a balance of $3700 to a new credit card at the beginning of the year. The card offered an introductory APR of 5.9% for the first 4 months
and a standard APR of 17.2% thereafter. If the card compounds interest
monthly, which of these expressions represents Felipe's balance at the end of
the year? (Assume that Felipe will make no payments or new purchases
during the year, and ignore any possible late payment fees.)

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.
