Jenny studied the characteristics of two species of bacteria.
The number of bacteria of species A, A(t), after t hours is represented by the function:

The number of bacteria of species B, B(t), after t hours is represented by the function:

N(t) denotes the difference in the number of bacteria; hence N(t) is given by after t hours as:
N(t)=A(t)-B(t)

which on simplifying gives:

Hence,
G (2) = -3 (-2) +5
= 6 + 5 = 11
g (0) = -3 (0) +5
= 0+5 = 5
g(3) = -3 (3) +5
= -9 +5 = -4

➷ Use this formula:
Area of circle = 
However, as we are using 3.14 for 'pi', we can write it like this:
Area = 
'r' is the radius which is 12ft
Substitute this value into the equation:
Area = 
Solve:
Area = 452.16
Multiply this value by 0.75 to get the answer:
452.16 x 0.75 = 339.12
339.12 square feet is being watered
