Answer:

$0.27

Step-by-step explanation:

1/4 The ratio of meters of streamers to cost of streamers is 1 : 0.09

     We want to know the ratio of centimeters of streamers to cost of  
     streamers.

2/4 We need to convert meters to centimeters.

      There are 100 centimeters in 1 meter.

      So, if 1 meter of streamers costs $0.09, then 100 centimeters of
      streamers also cost $0.09.

3/4 The ratio centimeters of streamers to cost for 300 centimeters of
      streamers.

      Now, we can find an equivalent ratio to find the cost for 300
      centimeters of streamers.

4/4 The streamers cost $0.27 per 300 centimeters.

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

The school printer has purchased a new color printer that can produce 75 pages in 5 minutes. If the printer were to print only 1
lawyer [7]

Answer:

15 pages

Step-by-step explanation:

This is a fairly simple problem meaning it has very few steps. If it makes 75 pages in 5 minutes you need to find out what the PPM or Page Per Minute is.

To find that you simply divide 75 by 5 and get 15 and in one minute the printer prints 15 pages.
