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
3 and 60 are the extremes while 15 and 12 are the means.
Find the last angle:
180-(30+90)
180-(120)
60
Evaluate using sine rule:

=

c=

=

=20
The length of line segment AB is 20 feet (answer choice C)
30 + 2x = 90
2x = 60
x = 30
Answer:
x = 30
Answer:
y = 14
Step-by-step explanation:
First find the slope of the line. To find the slope of the line, use the slope formula:

The slope of the line is 2.
Repeat this same process instead with points (1,4) and (6,y). Substitute m = 2.

So y = 14.
