11 A spoonful of sugar is dissolving in hot water. The initial mass of the sugar was 7 grams
and 5 minutes later the mass present had halved. The mass of sugar, S grams, at time
t minutes after it was placed in the hot water can be modeled by S(t) = S0e−kt, t ≥ 0.
a State the value of S0.
b Find the exact value of k.
c Sketch the graph of S(t).
d To the nearest second, how long after the sugar was
placed in the hot water was its mass 1 gram?
how do i graph part c on my calculator, which equation do i use to graph it?
