Answer:

Therefore the rate of growth of the tree is 33 cm/ yr.

Step-by-step 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 $=\frac{dH}{dt}$

∴H= 210 +33t

Differentiating with respect to t

$\frac{dH}{dt} =0 +33$

$\Rightarrow \frac{dH}{dt}=33$

Therefore the rate of growth of the tree is 33 cm/ yr.
