A volunteer knits a 5-foot long scarf at a constant rate. After 4 hours, the volunteer still has to knit 3 feet of the scarf. How much time does it take to knit the scarf from start to finish? What is the rate of change in this situation, and write this out in a complete sentence (which means you must add context--tell me what the rate of change means in this situation)

step-by-step explanation:

the answer should be a. snail

(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
