Considering the given function in the problem, it is found that:
a. 9.6 offspring survive to maturity when there are 12 female rabbits in the population.
b. At least 18 female rabbits are required for there to be 13 offspring.
<h3>What is the given function in this problem?</h3>
The function gives the relationship between the number of adult female rabbits F and the number of offspring R as follows:

When there are 12 female rabbits, we have that F = 12, hence:

9.6 offspring survive to maturity when there are 12 female rabbits in the population.
For at least 13 offspring, we have that the number of rabbits needed is given as follows:






At least 18 female rabbits are required for there to be 13 offspring.

Answer: 
Step-by-step explanation:
<h3>
Since the figure is not attached, below you can see a general explanation of the procedure to solve the exercise: </h3>
For this exercise you can apply the following formula, which is used to calculate the area of a trapezoid:

Where "B" and "b" are the bases of the trapezoid and "h" is the height.
So, substituting values into the formula and evaluating, you can find the area of trapezoid-shaped region.
Since the population in the trapezoid-shaped region is about 3,000 people, you can find the number of people per square mile dividing the population by the area of the region.
Then, the following expression represents the number of people per square mile in that region:

You can set up this equation as:

Because remember, 70% is equal to 0.7 and x represents the unknown value. So, let's just solve it:

So,
70% of 120 is 84.
The correct
answer is False.
Answer:
g(4) = -7
Step-by-step explanation:
g(x) = −2x + 1.
Let x=4
g(4) = -2*4 +1
= -8+1
= -7
