Calculus: Okay i have NO CLUE at how to do these. i have the answers and the algebra isn't hard but idk how to get to the answers or WHY something is the way it is. 'Why' is a big one.
Suppose silver is being extracted from a mine at the rate given by A'(t)=100e^(-.2t), where A(t) is measured in tons of silver and t in years from the opening of the mine.
a.) On a graph of A' draw a narrow rectangle of width Δt and show an input value t(sub)i within the rectangle.
b.) Write an equation for ΔA, the approximate amount of silver extracted in the time interval from t to t+Δt.
c.) Use a definite
