The radius of a circle is increased from 6.00 to 6.06.

Oksana_A [137]

Answer:

a) Change in area = 0.72π m²

b) Estimated change in %age = 2%

Step-by-step explanation:

$Initial\,\, radius = r = 6 m\\\\Final \,\,radius = r_1 = 6.06 m\\\\Change\,\, in\,\,radius = dr =6.06 - 6 = .06 m\\\\$

$Area\,\,of\,\,circle= A=\pi r^2\\\\A=36\pi \,m^2\\\\Chang\,\, in\,\, area = dA= 2\pi r.dr\\\\dA=2\pi(6)(.06)\\\\dA=0.72\pi\,m^2\\\\Estimated\,\, \%age\,\, change=\frac{0.72\pi}{36\pi}\times 100\%\\\\=2\%$

Consider the growth of a population p(t). It starts out with p(0)=A. Suppose the growth is unchecked, and hence p′=kp for some c

gayaneshka [121]

Answer:

$p(t) = Ae^{\frac{kt^2}{2}}$

Step-by-step explanation:

We are given the following information in the question:

The growth of population is given by the function p(t).

p(0)=A where A is a constant.

$p' = kp$

where k is a constant.

Solving the given differential equation, we have,

$p' = kp\\\\\displaystyle\frac{dp}{dt} = kp\\\\\frac{dp}{p} = kt~ dt\\\\\text{Integrating both sides}\\\\\int \frac{dp}{p} = \int kt~ dt\\\\\log p = \frac{kt^2}{2} + C\\\\\text{where C is the integration constant}\\\\\text{Putting t = 0}\\\\\log p_0 = C\\\\\log p = \frac{kt^2}{2} + \log p_0\\\\\log p - \log A = \frac{kt^2}{2}\\\\\log \frac{p}{A} = \frac{kt^2}{2}\\\\p(t) = Ae^{\frac{kt^2}{2}}$
