Problem 19.1. Find the amplitude, period, a
phase shift and the mean of the following si-
nusoidal functions.
(a) y = sin(2x - 7) + 1
(b) y = 6 sin(2x) - 1
(c) y = 3 sin(x + 2.7) + 5.2
(d) y = 5.6 (sin (x-7) – 12.1)
(e) y = 2.1 sin ( + 44.3) – 9.8
(1) y = 3.9 (sin(22.34(x + 18)) -- 11)
(g) y=11.2 sin ((x -9.2)) + 8.3

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?
