The bar graph in the following graphic represents fictional net exports in billions of dollars for five countries. Net
exports are obtained by subtracting total imports from total exports; a negative net export means the country
imported more goods than it exported.
Net Exports (Billions of dollars)
United States
Denmark
China
Germany
Spain
-100 -50 50 100
Net Exports (Billions of dollars)

What is the difference between the net exports from The United States and Denmark?
a 70 billion dollars
c. 90 billion dollars
b. 80 billion dollars
d. -140 billion dollars

step-by-step explanation:

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
