Problem

Jeff plants a 9-inch tomato plant in his garden. The plant grows by about $16 \%$ per week for several months. Which formula represents the height $h$ of the tomato plant (in inches) as a function of the time $t$ in weeks since it was planted?
$h=9(0.16)^{t}$
$h=9(1.16)^{t}$
$h=9(1.16 t)$
$h=9+0.16 t$
$h=9+1.16 t$

Answer

\(\boxed{h=9(1.16)^{t}}\) is the final answer.

Steps

Step 1 :The problem states that the plant grows by 16% per week. This means that each week, the plant's height is 116% of its height the previous week.

Step 2 :Therefore, the formula that represents the height of the tomato plant as a function of time would be the initial height of the plant multiplied by 1.16 raised to the power of the number of weeks since it was planted.

Step 3 :This corresponds to the formula \(h=9(1.16)^{t}\).

Step 4 :\(\boxed{h=9(1.16)^{t}}\) is the final answer.
