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
 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
 to obtain that rate of change at any instant. For example, if we derivate the function  we obtain:
 we obtain:

And if we want to find the rate of change at  years we evaluate
 years we evaluate
 rabbits/year
 rabbits/year

Answer:
Step-by-step explanation:
Find the required figure in the attachment. From the figure, <A = <B (alternate interior angle)
Given 
∠A=6x+5
∠B=4x+45 
Since <A = <B hence;
6x+5 = 4x+45
Collect the like terms
6x-4x = 45-5
2x = 40
Divide both sides by 2;
2x/2 = 40/2
x = 20
Hence the value of x is 20°
Next is to get the measure of <A
Since <A = 6x+5
Substitute x = 20° into the expression
<A = 6(20)+6
<A = 120+6
<A = 126°
Hence the measure of <A is 126°
