An airplane begins decreasing its altitude as it approaches the runway. At time t=1, the pilot notes that he has an altitude of 30,000 feet. One minute later, his altitude drops to 29,450 feet. One minute after that, his altitude drops to 28,900 feet. Assuming this pattern continues, write a recursive formula for the altitude of the plane A(t) after t
minutes.(1 point)

A(t)=30000−550(t−1)
upper a left parenthesis t right parenthesis equals 30000 minus 550 upper left parenthesis t minus 1 right parenthesis
A(t)=A(t−1)+550 for t>1
, where A(1)=30000
upper a left parenthesis t right parenthesis equals upper a left parenthesis t minus 1 right parenthesis plus 550 for t is greater than 1, where cap A times 1 is equal to 30000
