Question
Transcribed Image Text:In order to build better topsoil, tomato farmers are converting from using synthetic fertilizers to using
cover crops. This practice both adds nutrients to the soil and provides a mulch to keep plants cool and help
the soil retain water in sunny weather. In one region, 40, 000 pounds of fertilizer were being used in 2020.
This amount has decreased 6 % per year since then.
a) Assuming that decrease is exponential (with natural base e), find the function f(t) that represents the
amount of fertilizer used t year after 2020. Include "f(t)" in the answer.
formula for function: 17,272
x syntax error: this is not an equation.
b) In what year will the amount of pesticide used be half of the current amount? Round the answer DOWN
to the nearest year.
