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 
∴H= 210 +33t
Differentiating with respect to t


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

Answer:
6=b
Step-by-step explanation:
6=2(b-4)+2
6=2b-8+2
6=2b-6
12=2b
6=b
Answer: 1 1/4 (1 whole and 1/4)
6 1/4 = 25/4
5 = 5/1
(25/4)/(5/1) = (25/4)*(1/5)
(25/4)*(1/5)
25/20
1 5/20 = 1 1/4
