Answer:
Therefore the rate of growth of the tree is 33 cm/ yr.
Explanation:
Given that,
The height of the tree is
H= 210 +33t
Here H represent the height of tree in cm and t is time in year.
The rate of growth is the first order derivative of the H with respect to time.
i.e The rate of growth
![=(dH)/(dt)](https://img.qammunity.org/2021/formulas/mathematics/high-school/oaf6fer1mkhqvln50xdpthvdw3dg2hrcex.png)
∴H= 210 +33t
Differentiating with respect to t
![(dH)/(dt) =0 +33](https://img.qammunity.org/2021/formulas/mathematics/high-school/dj1bt1todj0lo20gjya2zwbjbdp849e57d.png)
![\Rightarrow (dH)/(dt)=33](https://img.qammunity.org/2021/formulas/mathematics/high-school/org9qkbvpbz4kd19ow3hhn1ldyn2e1f5zr.png)
Therefore the rate of growth of the tree is 33 cm/ yr.
