Step-by-step explanation:
Given equations are,


,
From the above equations,



First approximation,



Second approximation,



Third approximation,



Fourth approximation,



Fifth approximation,



Hence, by the Gauss Seidel method the solution of the given system is,



Answer/Step-by-step explanation:
a. Using two points on the line (0, 2) and (4, 12), find the gradient:
Gradient = ∆y/∆x = (12 - 2) / (4 - 0) = 10/4 = 2.5
Gradient = 2.5
b. The gradient, 2.5, represents the unit rate. That is, the volume of the oil in the tank per second.
i.e. 2.5 litres per second
c. The value, L = 2 represents the y-intercept, which is the starting value or initial volume of oil in the tank at 0 secs.
