Bacteria length = 1mm
It will triple four times by 40 min.
This can be shown as 3 to the power of 4; 3⁴ = 81
Original length * growth factor = final length
1 mm * 81 = final length
81 = final length
After 40 mins, the bacteria colony will be 81 mm in length.
Answer: Each shape has 4 sides so there are all quadrilaterls.

Answer: 0.9 is the decreasing factor.
Step-by-step explanation:
Here, The price of the ginger roots is G .
And, It there occurs the 10% off on this amount then,
The new price of the ginger is 90% of G.
That is, Final price of G =
=
= 0.9G
Since, 0.9 decreases the price of the ginger.
Therefore, It is called decreasing factor for the function which represents the price of the ginger.
