To solve this problem, let’s go through each part step-by-step.

(a) Calculate the height of the tree and complete the table.

The exponential growth of the tree’s height can be expressed as: $P(t) = P_0 e^{kt}$ where:

• $P_0$ is the initial height of the tree,
• $k$ is the growth rate,
• $t$ is the time in years.

Given: $P(1) = 1.5e^{22}$

Since it’s not clear from your input what values of $t$ we need for the table, could you please confirm the specific years (values of $t$)? I’ll proceed with calculations once I have these values.

(b) Draw the graph for Height (m) against Time (year).

Once the table values are complete, I’ll plot a graph of height against time.

---

(c) Using the graph, find the time when the height of the tree doubles.

The time at which the height of the tree doubles can be calculated by setting $P(t) = 2P_0$ and solving for $t$. This will correspond to the point where the height reaches twice its initial value.

To proceed accurately:

1. Could you provide the initial height $P_0$ of the tree if it differs from $1.5$?
2. Confirm the time values needed for the table.

Once I have these details, I’ll complete each part accordingly.
