An experimental electrical system has a voltage that can be modeled by V(t) = 0.4t3 + 6.4t2 + 6t, where t represents time in seconds. The resistance in the system also varies and can be modeled by R(t) = t + 1. The current I is related to voltage and resistance by the equation I = V/R
. Write an expression that represents the current in the system.
The expression that represents the current in the system is

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.
