The first terms of an infinite geometric sequence, un are 2, 6, 18, the first terms of a second infinite geometric sequence, vn are 2, -6, 18, - the terms of a third sequence wn are defined as wn = un + vn

1. the finite series, summation: upper limit= 225, lower limit k=1, formula wk
can also be written in the form summation: upper limit= m, lower limit k=0, formula 4r^k.
find the value of r.

2. find the value of m

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?

If given an equation of a line such as -1/2x+6 how would you create an equation of a line parallel and perpendicula to this line that goes through another point such as (4,10)

What is the solution to the equation? k/6.4=8.7 2.3 5.568 15.1 55.68
