Newborn blue whales have a length of about 24 feet and weight 3 tons. These young whales are breast-fed for 7 months, and when they stop, they have a length of about 53 feet and a weight of 23 tons. If t denotes the age of the whale (in months) and L its length (in feet), express L as a linear function of t. According to this linear model, how much does the length increase every day? (Use 1 month=30 days). Express W as a linear function of t. What is the daily increase of the weight? Express W as a linear function of L.
