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.

In 2003, the population of an African country was about 22.5 million people, which is 2 million more than 5 times the population
Anton [14]

Answer:

Population in 1950 was 4,100,000

Step-by-step explanation:

Equation: 5x + 2,000,000 = 22,500,000

Subtract 2,000,000 from each side: 5x = 20,500,000

Divide each side by 5: x = 4,100,000

Please help will mark brainliest for the right answer
hodyreva [135]

Answer:

a).  x + y + 90° = 180°

b).  x = 67°

    y = 23°

Step-by-step explanation:

The sum of all angles in a triangle is 180°.

One of the angles in the figure is a right angle, or 90°.  Therefore the sum of the three angles in the figure is:

x + y + 90 = 180

We are also told that x + 2 = 3y.  

Rearranging that to isolate x gives us:  

x = 3y - 2

Thake the first equation and substitute the above expression of in place of x:

x + y + 90° = 180°

(3y-2) + y + 90° = 180°

4y + 88° = 180°

4 y = 92°

y = 23°

To find angle x, use y = 23°

x = 3y - 2

x = 3*(23°) - 2

x = 67°

The sum 90° + 67° + 23° = 180°

Decide if the function is an exponential growth function or exponential decay function, and describe its end behavior using limi
Tems11 [23]

Answer:

Exponential Decay

Its end behavior on the left is as follows as x approaches negative infinity y approaches positive infinity. Its end behavior on the right is as follows as x approaches positive infinity y approaches negative infinity.

Step-by-step explanation:

We can graph the function by graphing two points when x=0 and x=1.

x=0 has y=7^{-x} =7^{0} =1

x=1 has y=7^{-x} =7^{-1} =\frac{1}{7}

This function starts with higher output values and decreases over time. This is Exponential Decay. Its end behavior on the left is as follows as x approaches negative infinity y approaches positive infinity. Its end behavior on the right is as follows as x approaches positive infinity y approaches negative infinity.
