Michael works in the marketing department of a company. he recorded the sales of his company for 10 consecutive months. the amount of sales, n(t), over time t, in months, can be modeled by a cubic function. each of the following functions is a different form of the cubic model for the situation given above. which form would be the most if attempting to determine the number of months after which the sales were approximately constant? a) n(t) = 0.1(t - 8)3 + 51.2 b) n(t) = 0.1t2(t - 24) + 19.2t c) n(t) = 0.1t3 - 2.4t2 + 19.2t d) n(t) = 0.1(t3 - 24t2 + 192t)

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?
