Lori is president of a book club. She has a message she wants to get out to her book club members. On Monday, she called one member and asked that member to call two other members by noon the next day and
repeat the message. How many calls were made by Friday afternoon?

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

(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

can you post the graph?
