Answer:
answer::::: 9 . Is it true ?
N = number of people = constant
number of people who have adopted the new technology: x(t) = x
number of people who have not adopted the new technology: n - x
proportionality constant: k
dx / dt = kx(1-x)
x(0) = 0 (this is at t = 0, 0 people have adopted the new technology)
So the original area is 300*150 (or 45000 ft^2), but now the new area is (300+3y)(150+3y).
The polynomial in standard form would be 45000+900y+450y+9y^2=45000+1350y+9y^2
But the proper way to write it is 9y^2+1350y+45000
When y=4, we get 9(4^2)+1350(4)+45000=9(16)+54000+45000=144+99000=99144
So the new area would be 99144 ft^2
Hope this helped!
