For their homecoming parade, the students of U-Math have created a colorful banner, 51 meters in length, that is made of two pieces of parachute material. The short piece is 21 meters shorter than the longer piece. Find the length of each piece.

Length of long piece= 36 m

Length of the short piece= m

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75
