For a certain type of tree the diameter D (in feet) depends on the tree's age t (in years) according to the logistic growth model. Find the diameter of a 21-year-old tree. Please give the answer to three decimal places.

Step-by-step explanation:

The question has missing details;

Given that t = 21

Solve for Diameter, D

To do this, we simply substitute 21 for t in the above function

becomes

Solve for

Simplify the denominator

(Approximated)

Hence, the diameter of the 21 year old tree is 1.612 feet

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
