Let f (t) be the amount of yeast (in grams) in a culture of yeast at time t (in minutes), and let g (t) represent the rate at which the culture of yeast is growing (in grams/min) at time t (in minutes).
1. (a) Write an expression in terms of f (t) for the amount the culture grew (in grams) from 25 to 30 minutes.
2. (b) Write an expression in terms of g (t) for the amount the culture grew (in grams) from 25 to 30 minutes.
3. (c) Write an expression in terms of f (t) for the average amount of yeast in the culture (in grams) from 25 to 30 minutes.
4. (d) Write an expression in terms of f (t) for the average rate at which the culture of yeast grew (in grams/minute) from 25 to 30 minutes.
5. (e) Write an expression in terms of g (t) for the average rate at which the culture of yeast grew (in grams/minute) from 25 to 30 minutes.
6. (f) Suppose at 20 minutes the amount of yeast in the culture was 100 grams. Write an expression using g (t) representing the amount of yeast in the culture at 30 minutes.

Let f(t) be the weight (in grams) of a solid sitting in a beaker of water after t minutes have elapsed. Suppose that the solid dissolves in such a way that the rate of change (in grams/minute) of the weight of the solid at any time t can be determined from the weight using the forumula: f′(t)=−4f(t)(6+f(t)) If there is 1 grams of solid at time t=2 estimate the amount of solid 1 second later.
