Answer:

10 pairs of socks for $11.99

Step-by-step explanation:

6.99/6 = 1.165

1.99/10 = 0.199

0.199 < 1.165

Answer:

6 pairs of socks for 6.99.

Step-by-step explanation:

Because 11.99 is almost $12 and 6.99 is almost $7, so 6 for 7 is better than 10 for 12. Also if you divide 11.99 by 10 you get 1.199 and if you divide 6.99 by 6 you get 1.165.

If the diameter of the circle is 24 cm, find its area correct to 1 decimal place.
Blababa [14]

Answer:

452.4 cm^2

Step-by-step explanation:

Use the area formula A = πr².  With d = 24 cm, r = 12 cm, and so the desired area is

A = π(144 cm^2) = 452.4 cm^2

D^2(y)/(dx^2)-16*k*y=9.6e^(4x) + 30e^x
MA_775_DIABLO [31]
The solution depends on the value of k. To make things simple, assume k>0. The homogeneous part of the equation is

\dfrac{\mathrm d^2y}{\mathrm dx^2}-16ky=0

and has characteristic equation

r^2-16k=0\implies r=\pm4\sqrt k

which admits the characteristic solution y_c=C_1e^{-4\sqrt kx}+C_2e^{4\sqrt kx}.

For the solution to the nonhomogeneous equation, a reasonable guess for the particular solution might be y_p=ae^{4x}+be^x. Then

\dfrac{\mathrm d^2y_p}{\mathrm dx^2}=16ae^{4x}+be^x

So you have

16ae^{4x}+be^x-16k(ae^{4x}+be^x)=9.6e^{4x}+30e^x
(16a-16ka)e^{4x}+(b-16kb)e^x=9.6e^{4x}+30e^x

This means

16a(1-k)=9.6\implies a=\dfrac3{5(1-k)}
b(1-16k)=30\implies b=\dfrac{30}{1-16k}

and so the general solution would be

y=C_1e^{-4\sqrt kx}+C_2e^{4\sqrt kx}+\dfrac3{5(1-k)}e^{4x}+\dfrac{30}{1-16k}e^x
