Just need a little help. Thanks
Use the given information to create a cosine function:

1. Amplitude: 2

Period: 2Π/5

_

2. Amplitude: 5

Period: 4Π

_

3 and 4: Write the equation of the following cosine curves: ( Refer to the images)
5. In your own words, what is the main difference between graphing a sine function compared to graphing a cosine function?

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.
