If r() is the rate of growth of a certain tree in feet per year where , is in years, what does the expression , r()di represent? 2. A population of rabbits starts off at time / = 0 with 225 rabbits and increases at a rate of (!) rabbits per month, where , is in months. A. What does the expression | 24 (35r()di represent? B. What does the expression 225 + ]," r(1)di represent? C. Suppose you're told that ? for(1)di = 4.25. How many rabbits are there in the population after 2 years?Calculus AB Assignment Practice with the Definite Integral as Accumulated Change 3. The marginal cost for producing x units of a certain product is given by the formula 14C = 0.001x2 - 0.5x + 66.5. A. What is the increase in the cost of the production if the production level is raised from 200 to 400 units? You may use your calculator here. Hint: Remember that marginal cost is the rate of change of the cost of production. B. What is the average cost per item of producing 330 items? You may use your calculator. 4. Below is a graph of the function ((x) : y = /(x ) For what value of 0 is the average value of (x) on the interval [-S,
