Rate of growth of snake, when it is $5$ $5$ years old, is $\frac{7}{30}$ $7/30$ meters per year.

Explanation:

The length $x$ $x$ metre of green anaconda snake, which is $t$ $t$ years old, is given approximately by formula $x = 0.7 \sqrt{2 t - 1}$ $x=0.7sqrt(2t-1)$ , where $1 < t < 10$ $1 < t < 10$ .

At an ageof $5$ $5$ tears its length would be

$0.7 \sqrt{2 \cdot 5 - 1} = 0.7 \sqrt{9} = 0.7 \cdot 3 = 2.1$ $0.7sqrt(2*5-1)=0.7sqrt9=0.7*3=2.1$ meters.

As $x = 0.7 \sqrt{2 t - 1}$ $x=0.7sqrt(2t-1)$ , rate of growth $\frac{d x}{d t}$ $(dx)/(dt)$ is given by

$\frac{d x}{d t} = 0.70 \times \frac{1}{2 \sqrt{2 x - 1}} \times 2 = \frac{0.7}{\sqrt{2 x - 1}}$ $(dx)/(dt)=0.70xx1/(2sqrt(2x-1))xx2=0.7/sqrt(2x-1)$

and rate of growth of snake when it is $5$ $5$ years old is

$\frac{0.7}{\sqrt{2 \cdot 5 - 1}} = \frac{0.7}{3} = \frac{7}{30}$ $0.7/sqrt(2*5-1)=0.7/3=7/30$ meters per year
