Triangle ABC is shown. AC = 4, and AB = 8. CB = a. What is the length of BC to the nearest tenth?​

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

This is so hard and it’s for a test

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.
