Birth and death rates of animal populations typically are not constant; instead, they vary periodically with the passage of seas

Dominik [7]

Answer:

We readily separate the variables and integrate:

∫dP/P=∫(k+bcos2 $\pi$ t)dt

ln P=kt+(b/2 $\pi$ )*sin2 $\pi$ t+ln C

Clearly C = Po, so we find that P(t) = Poexp(kt + (b/2 $\pi$ )* sin 2 $\pi$ t). The 271- curve with the typical numerical values P_o = 100, k = 0.03, and b = 0.06. It oscillates about the curve which represents natural growth with P_o and k = 0.03. We see that the two agree at the end of each full year.

P(x) =x and q(x) = x-1Given:minimum x and Maximum x: -9.4 and 9.4minimum y and maximum y: -6.2 and 6.2Using the rational functio

Arte-miy333 [17]

we have the following function

$\frac{p(x)}{g(x)}=\frac{x}{x\text{ -1}}$

where x is between -9.4 and 9.4 and y is between -6.2 and 6.2.

We will first draw the function

from the graph, we can see that the zeroes are all values of x for which the graph crosses the x -axis

In this case, we see that that the only zero is at x=0.

Now, we have that the asymptotes are lines to which the graph of the function get really close to. On one side, we can see that as x goes to infinity or minus infinity, the values of the function get really close to 1. So the graph has a horizontal asymptote at y=1. Also, we can see that as x gets really close to 1, the graph gets really close to the vertical line x=1. So the graph has a vertical asymptote at x=1.

Recall that the domain of a function is the set of values of x for which the function is defined. From our graph, we can see that graph is not defined when x=1. So the domain of the function is the set of real numbers except x=1. Now, recall that the range of the function is the set of y values of the graph. From the picture we can see that the graph has a y coordinate for every value of y except for y=1. So, this means that the range of the function is the set of real numbers except y=1.

From the graph, we can see that we cannot draw the graph having a continous drawing. That is, imagine we take a pencil and start on one point on the graph on the left side. We can draw the whole graph on the left side, but we cannot draw the graph on the right side without lifting the pencil up. As we have to "lift the pencil up" this means that the graph is not continous

Finally note that as we have a vertical asymptote at x=1 and horizontal asymptote at y=1 we have that when y is 1 or x is 1, the function y=f(x)/g(x) is undefined

During their summer break from school. Hortencia and Alex decide to paint houses to earn money. Hortencia charges a flat rate of

PIT_PIT [208]

Answer:

The answer to your question is: 20 hours.

Step-by-step explanation:

Data

Hortencia = $350

Alex $18 / h

# hours Alex must paint to make more money than Hortencia = ?

Process

Equation 18 x n > 350

n > 350 / 18

n > 19.4 hours

If Alex work 19.4 hours, he will make the same amount of money than Hortencia, then He needs to work 20 hours.

Given the graph of the quadratic function, identify the solutions.

Veronika [31]

<h3>Answer: -6 and 0</h3>

Explanation:

The solutions, or roots, are the x intercepts of the graph. This is where the curve crosses or touches the x axis. In this case, the two x intercepts are -6 and 0.
