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

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.

(05.02)a farmer has decided to divide his land area in half in order to plant soy and corn. calculate the area of the entire area so he knows how much soil is needed. a parallelogram with a height of 6 yards and side length 9 yards. the height forms a triangle with the slanted side of the rhombus with a base of 2.5 yards. rhombus is split into a soy half and a corn half. each bag of soil covers 40 square yards. how many bags should the farmer purchase?
