Finding the Constant of Proportionality from a Graph A graph titled Swimming Pool has time (hours) on the x-axis and Depth of Water (feet) on the y-axis. At 1 hour the depth is 1.5; 2 hours, 3 feet; 3 hours, 4 feet; 4 hours, 6 feet. Pauly is filling his swimming pool with water at a constant rate. The graph shows the amount of water added over time. What is the unit rate? 1 foot per hour 1.5 feet per hour 2.5 feet per hour 3 feet per hour

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.
