Explanation for Question 8 From the Math (Calc) Section on the 2018 March Sat
Question eight says which of the following could be a graph of the reservoirs 2 capacity C in acre feet as a function of time T in 3 years after 1928. So what we know is we know 4 that the, uh, reservoir's capacity is decreasing, 5 right? It's reducing. And we know that it's decreasing at a constant 6 rate of 1,700 feet that 7 tells us that whatever a graph should look like it should be decreasing. 8 So one decreasing and two constant, 9 the slope should be constant. And there's only 10 one graph that looks like that. And that's.
