Circle A and circle B are congruent. CD is a chord of both circles. If AB = 8 ft and CD = 6 ft, how long is a radius?

bazaltina [42]

Let us say that the intersection point of lines AB and CD is called point E. The lines AB and CD are perpendicular to each other which also means that the triangle CEB is a right triangle.

Where the line CB is the radius of the circle while the side lengths are half of the whole line segment:

EB = 0.5 AB = 0.5 (8 ft) = 4 ft

CE = 0.5 CD = 0.5 (6 ft) = 3 ft

Now using the hypotenuse formula since the triangle is right triangle, we can find for the radius or line CB:

CB^2 = EB^2 + CE^2

CB^2 = (4 ft)^2 + (3 ft)^2

CB^2 = 16 ft^2 + 9 ft^2

CB^2 = 25 ft^2

<span>CB = 5 ft = radius</span>

In the study of population dynamics one of the most famous models for a growing but bounded population is the logistic equation

MA_775_DIABLO [31]

Answer:

If $K$ is a constant of integration, then

$P = {\displaystyle \frac{1}{b/a + Ke^{-at}}}$

Step-by-step explanation:

According to the information of the problem we know that

$\frac{dP}{dt} = P(a-bP)$

Remember that in general a Bernoulli equation is an equation of the type

$y' + p(x)y = q(x)y^n$

And the idea to solve the equation is to substitute

$v = y^{1-n}$

Now for this case

$\frac{dP}{dt} - Pa = -bP^2$

Then we substitute

$v = P^{1-2} = P^{-1}$

Therefore

$P = v^{-1}$

and if you compute the derivative of that you get that

$\frac{dP}{dt} = -v^{-2} \frac{dv}{dt}$

Now you substitute that onto the original equation and get

$\frac{dP}{dt} - Pa = -bP^2$

$-v^{-2} \frac{dv}{dt} - v^{-1} = -bv^{-2$

If you multiply everything by $-v^2$ you get that

$\frac{dv}{dt} + v = b$

That's a linear differential equation and the solution would be

$v = {\displaystyle \frac{b}{a} + Ke^{-at}} = P^{-1}$

Where $K$ is a constant of integration, then

$P = {\displaystyle \frac{1}{b/a + Ke^{-at}}}$
