A population of will grow at a rate given by l 3 w'(t) = (3t+2) , where w is the weight (in milligrams) after t hours. Find the net change in weight of the population from t = 1 to t = 4. a) Which of the following is the correct method for finding the change in weight of the population from t = 1 to t = 4? 0 Compute w'(4) w'(1) 0 Find the definite integral of w'(t) from 1 to 4 0 Compute 10(1) w(4) O Find an indefinite integral of w'(t) and then plug in 4. b) The net change in weight of the population it = 1 to t = 4 is milligrams. Round to 3 decimal places as needed
