Answer

A. 50 B. At V(0), the tank is full. At V(20), the tank is empty. C. 0 50 5 28.125 10 12.5 15 3.125 20 0 D. Change in Volume = V(20) - V(0) = 50 - 0 = 50 gal

Work Step by Step

A. V(0)=50(1-$\frac{0}{20}$)$^{2}$ =50(1-0)$^{2}$ =50 V(20)=50(1-$\frac{20}{20}$)$^{2}$ =50(1-1)$^{2}$ =0 C. t | V(t) 0 | 50 5 | 28.125 10 | 12.5 15 | 3.125 20 | 0 D. This problems asks you to find the difference between the two inputs from part A: 50-0=50
