Plz ! find the y-intercept of the following equations. y=3^x y=0.25^x y=-(2^x) y=2(0.3)^x y=2^x-3 (-3 is not part of the exponent) y=4(0.5)^x+5 (-5 is not part of the exponent)

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.
