The initial cost for Travis and his band to record their first CD was $1500. Each CD will cost $4 to produce. If they sell their

a_sh-v [17]

C=1500+4x where x is cds, C is cost
R=10x where R is revenue
then, P=R-C
P=10x-1500-4x
P=6x-1500
set P=0
1500=6x
x=250
check, C=1500+4*250, R=10*250
C=250, R=250
They need to sell 250 cds before they make profit

First change to standard form of first order linear differential equation and then by finding the appropriate integrating factor

Leokris [45]

Answer:

Step-by-step explanation:

Given is a Differential equation as

$xy' + y = lnx ; y(e)=1$

To bring it to linear form we can divide the full equation by x

$y'+\frac{y}{x} =\frac{ln x}{x}$

This is of the form

y'+p(x) *y = q(x)

p(x) = 1/x

So find

$e^{\int\limits{\frac{1}{x} } \, dx } = e^{ln x} = x$

Solution is

$xy = \int {x*lnx /x } \, dx =xln x -x +C$

Use the initial value as y(e) =1

$e= eln e -e+C\\C=e$

So solution is

$xy =xln x -x+e$

1)The base of a triangular prism is a right triangle with a base of 20 feet and a height of 120 inches. The height of the prism

ivanzaharov [21]

Answer:

(1)750 cubic feet

(2)8 Times

Step-by-step explanation:

Question 1

Dimensions of the Right Triangular Base

Base = 20 feet
Height= 120 inches = 10 feet

Base Area of the Prism

$=\dfrac12 \times 20 \times 10\\=150$ square feet$

Height of the Prism = 5 feet

Volume of the Prism = Base Area X Height

= 150 X 5

=750 cubic feet

Question 2

Jake's Box

Length: 12 inches
Width: 4 inches
Height: 8 inches

Volume = 12 X 4 X 8 =384 cubic inches

Havana's box

Havana has a shipping box similar to Jake's box, but each dimension is half as long.

Therefore:

Length: 12/2=6 inches
Width: 4/2=2 inches
Height: 8/2=4 inches

Volume = 6 X 2 X 4 =48 cubic inches

Now:

384/48=8

Therefore, the volume of Jake's box is 8 times larger than Havana's box.
