Which of the following statements best summarizes the main points of the passage? A There are three types of plate boundaries: divergent, convergent, and transform. B In 2011, an earthquake measuring 8.9 on the Richter scale shook the ocean floor. It made a giant wave which grew up to 30 feet (9.14 meters) tall. C Tectonic plates have always moved and always will. D Scientists study plate boundaries in order to understand tectonic movement, understand more about how plate movements can result in earthquakes, tsunamis, and volcanic eruptions, and explore how to predict these events.

i'm sorry i don't know

step-by-step explanation:

(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
