A publishing company expects to sell 5000 copies of a new book from its web site, if the company charges $30 per book. The company expects that 500 more books would be sold for each price reduction of $2. What price would maximize the company's revenue?

Answers

Answer 1

Solution :

Let the revenue be = R

Therefore, R = price x quantity

                  R = (30 - 2x) ( 5000 + 500x)

                     = [tex]150000 + 5000x - 1000x^2[/tex]

For the maximum revenue,

[tex]$\frac{dR}{dx} = 0$[/tex]

[tex]$-2000x+5000=0$[/tex]

[tex]$x=2.5$[/tex]

[tex]$\frac{d^2R}{dx^2}=-2000<0$[/tex]

At [tex]x=2.5[/tex], the revenue is maximum.

So the price for the maximum company revenue = [tex]$30-2x$[/tex]

                                                                                  [tex]$=30-2(2.5)$[/tex]

                                                                                  = 30 - 5

                                                                                  = 25

Therefore, the price that will maximize the company's revenue is $25.

What is the slope of (-3, -2) and (-1, -5) ??

Answers

Answer:

-3/2 or -1 1/2

Step-by-step explanation:

The slope, plugging into the equation (y_2-y_1)/(x_2-x_1) would be -5 + 2 / -1 + 3, or -3/2, which can also be - 1 1/2

Answer:

-3/2

Step-by-step explanation:

slope ('m') formula:  (difference of the y-values) ÷ (difference of the x-values)

m = -2-(-5) ÷ -3-(-1)

m = 3 ÷ -2

slope = -3/2

Let the breadth of the rectangle be x cm lenght of the rectangle = ( x + 5 ) cm

perimeter of the rectangle = 2 ( l + b )

2 ( x + x + 5 ) cm 2 ( 2x + 5') cm ( 4x + 10 ) cm

4x + 10 = 40

4x = 40 10 ( transpose 10 to RHS )

x = 30/4 = 7.5 ( divide both sides by 4 )

lenght of the rectangle = x + 5 = 7.5 + 5 = 12.5 cm breadth of the rectangle = x = 7.5 cm

Breadth be xLength be x+5

Answers

Answer:

y=2.5x - Proportional  

y= x - 4 - Not Proportional  

Step-by-step explanation:

A linear function that is proportional is in the form y =kx (k is the constant of variation) and passes the origin.

The first equation given is in this form (2.5 is the constant) and it passes through the origin. It is proportional.

However, the second one is not proportional is it does not pass the orgin and it's not in y=kx form.

8. The distance from Earth to the Sun is approximately 9 x 10^7 miles. The distance from Earth to the Moon is approximately 2x10^5 miles. Approximately how many times the distance from the Earth to the Moon is the distance from Earth to the Sun?
A. 450
B. 222
C. 45
D. 18​

Answers

Answer:

A

Step-by-step explanation:

To find how many times the distance, we divide the distance to the sun by the distance to the moon.

we get:

(9 * 10^7) / (2 * 10^5)

First, lets isolate and simplify the powers of 10.

(9 /2) * (10^7/10^5)

(9/2) * (10^2)=(9/2) * 100

Solve

9/2*100=4.5*100=450

The perimeter of a rectangle is 18 inch. The length is three inches more than width. What is length?

Answers

Answer:

6 inches.

Step-by-step explanation:

If the width is x inches then the length is x + 3.

S0

Perimeter = 2x + 2(x +3)

18 = 2x + 2x + 6

4x = 18 - 6 = 12

x = 3.

So the length = 6 inches.

Perimetre = 18 inch

Let the width be x

length = x+3

Perimetre of rectangle = 2(length+width)

18 = 2[(x+3)+x]

18 = 2(2x+3)

18 = 4x+6

4x = 18 - 6

4x = 12

° x = 12/4 = 3

Length = x+3 = 3+3 = 6

° The length of rectangle is 6 inch.

In a certain town, 80% of all married men are working, and 75% of all married men are over 35 years old. Among working married men, 70% are over 35 years old. What proportion of non-working married men are over 35 years old?
answer: 95%
working is needed​

Answers

It helps to set up a two way table as shown below. Such tables compare 2 different variables. In this case, we're comparing the variables "working status" and "age".

Specifically, the working status separates the men into "working vs non-working". The age variable splits the men into groups of "35 or younger" and "over 35". Usually, but not always, each variable will take on two values.

Let's say this town had 1000 married men. 80% of this is 0.80*1000 = 800 to indicate there are 800 married working men. So we write this in the "total" column for the "working" row. This leaves 1000-800 = 200 nonworking married men, which will go right under the 800.

We're told that 75% of the married men are over 35, so 0.75*1000 = 750 married men are over 35. This goes in the "total" row for the "over 35" column. There are 1000-750 = 250 married men who are 35 and under.

As you can see, the stuff in the total column and the total row must add back to the grand total of 1000 married men overall.

--------------------------------

Another bit of info given is that "Among the working married men, 70% are over 35". We'll only focus on the "working" row. We have 800 total and 70% of this is 0.70*800 = 560 which is the number of working married men over 35. This leaves 800-560 = 240 married men who are not over 35.

At this point, we have 2 spots left in the table. Through guess and check, or using algebra, you should find that there are 190 non-working men over 35 and 10 non-working men who aren't over 35. Make sure that each row and column total checks out.

--------------------------------

By now, the table is fully filled out. See below.

Your teacher now asks "what proportion of non-working married men are over 35 years old?" which means we'll only focus on the "non-working" row. There are 200 men total here, and of this total, 190 are over 35.

So, 190/200 = 0.95 = 95% of the non-working married men are over 35.
