The answer to the completed table are
are f(0) = 20, f(1) = 20/3, f(2) = 20/9, f(3) = 20/27
The height of this water can regarded as a function of time.
The function can be written as
[tex]f(t) = 20*(\frac{1}{3})^t[/tex]
We have to fill in the value of t at all points in the table into the formula that have been written above.
f(t) = 0
[tex]f(t) = 20*(\frac{1}{3})^0\\\\= 20[/tex]
F(t) = 1
[tex]f(t) = 20*(\frac{1}{3})^1\\\\\frac{20}{3}[/tex]
f(t) = 2
[tex]f(t) = 20*(\frac{1}{3})^2 \\\\= \frac{20}{9}[/tex]
for f(t) = 3
[tex]f(t) = 20*(\frac{1}{3})^3\\\\= \frac{20}{27}[/tex]
