There's two questions. Read carefully

A yeast culture weighing 2 grams is removed from a refrigerator unit and is expected to grow at the rate of W'(t) = 0.1 e 0.4t v. grams per hour at a higher controlled temperature. How much will the weight of the culture increase during the first 8 hours of growth? How much will the weight of the culture increase from the end of the 8th hour to the end of the 16th hour of growth? . . . The weight increase during the first 8 hours is approximately grams. (Type an integer or decimal rounded to three decimal places as needed.)
