Question

(11) Weight of a Humpback Whale. Researchers have found that the weight (in tons) of a Humpback Whale is linearly related to its length (in feet). Two measurements that researchers found were that for a length of 35 feet the weight is 16,0 tons and for a length 44 feet the weight is 38 tons. All resulting coefficients should be exact fractions, mixed fractions or integers. [Remember for part (a) you are finding a linear equation relating Wand 1] (a) Express W in terms of L. (b) At what length will the whale be 20 tons? 2 (12) Graph and list at least two points for each part. - X + 2 if x < -2 f(x) = x² - 4 if - 2 Sx<3 -2 if x 2 3 x f(x)
