<h3>Answer:</h3>
- 1 1/8 in
- 4 7/8 cm²
In both cases, you make use of the relationship between the length and width of a rectangle and its area. We take for granted that you are comfortable with arithmetic using mixed numbers and/or fractions. The applicable formula for the area (A) of a rectangle in terms of its length (L) and width (W) is ...
A = L·W
Fill in the given values and solve for the remaining one.
1.
3/4 in² = (2/3 in)·W . . . . . divide by the coefficient of W to find W.
(3/4 in²)/(2/3 in) = W = 9/8 in = 1 1/8 in
2.
A = (1 1/2 cm)·(3 1/4 cm) = (3/2·13/4) cm² = 39/8 cm²
A = 4 7/8 cm²

Answer:
The concept which best describes the change of the population is the derivative of .
Step-by-step explanation:
Observe that the function describes the amount of rabbits at the time t (in years) but no the rate of change of the population at a given instant. So you have to use the derivative of
to obtain that rate of change at any instant. For example, if we derivate the function
we obtain:
And if we want to find the rate of change at years we evaluate
rabbits/year
