For a given rabbit population, the relationship between the number of adult female rabbits, F, and the number of offspring, R, t
Sphinxa [80]

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:

R = 3 + \frac{350F}{F + 625}

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

R = 3 + \frac{350 \times 12}{12 + 625} = 9.6

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:

R \geq 13

3 + \frac{350F}{F + 625} \geq 13

\frac{350F}{F + 625} \geq 10

350F \geq 10F + 6250

F \geq \frac{6250}{340}

F \geq 18

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

The financial planner for a beauty products manufacturer develops the system of equations below to determine how many combs must
Nina [5.8K]

The price of each comb is $0.5, and the total income from selling x plastic combs is y = x/2

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

The linear equation y = x/2 models the income, in dollars, from selling x plastic combs. Hence:

Price of each comb = (x/2) / x = 0.5

The price of each comb is $0.5, and the total income from selling x plastic combs is y = x/2
