Aproperty owner on a lake is given an aluminum dock for his property. unfortunately the dock is too large and heavy to move over land. instead the owner has this idea (which his family thinks is insane) to move the dock by water. the dock is 20 ft long, 3ft wide, and weighs 500 lbs. the owner decides to float the dock using 50 gallon plastic drums filled with air. (a) (6 points) how many 50 gallon drums are required to float the dock? (b) (4 points) how many would you recommend the home owner actually use and in what configuration? why?

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
