Answer:

next time put the whole question but

a)  In the cost function you have a fixed cost and a variable cost.  The variable cost is the slope of the line and the fixed cost is the y-intercept so we can say:

c(x)=4x+1550

b)  If you want to break even at 50 books, let p equal the price you need to charge, then we will need to create a profit function.  Profit equals revenue minus cost.

r(x)=px and c(x)=4x+1550, so P(x) (P(x) is the Profit function:

P(x)=r(x)-c(x) so:

P(x)=px-4x-1550

And we wish to break even at 50 books, so P(50)=0:

50p-4(50)-1550=0

50p-1750=0

50p=1750

p=$35.00

So you must price the book at $35.00 so that you break even when you sell 50 books.

c)

The income function is just like the profit function that we found in the last problem, and if we use the price found in that equation we have:

P(x)=35x-4x-1550

P(x)=31x-1550

d)

The variable cost should be the same, the fixed cost SHOULD go up because you have spent $200.00 more for research.  The cost function should now be:

c(x)=4x+200+1550

c(x)=4x+1750

But now our revenue function has changes since we are changer our price to $20 per book, And since P(x)=r(x)-c(x) we have:

P(x)=20x-4x-1750

P(x)=16x-1750

Answer:

x = 9

Step-by-step explanation:

4(5 + 4) = 3(x + 3) => Intersecting secants theorem

4(9) = 3(x + 3)

Open bracket by applying distributive property

36 = 3x + 9

Subtract 9 from each side

36 - 9 = 3x + 9 - 9

27 = 3x

Divide both sides by 3

27/3 = 3x/3

9 = x

x = 9

Answer:

Last Option

Step-by-step explanation:

Last one because the dot on top of the 4 is filled in and that means it can also equal 4. The rest of the line is going to the right of the 4 so x will be more than 4. The little line below the more than sign means it can also equal 4. Hope this helped :)

Answer:

Option D, x ≥ 4

Step-by-step explanation:

Rule 1: Closed circle: the inequality sign with a line at the bottom, its called greater than or equal to (≥), and less than or equal to (≤), that means that the number 4 is included in the data set.

Rule 2: Since the line is going to the right of 4, there are values greater than 4 in the data set which means x (any value) has to be greater than 4.

So bringing both rules together the equation would be: x ≥ 4

The surface area of the prism is 294yd²

The area occupied by a three-dimensional object by its outer surface is called the surface area. The prism is a square prism also called cube.

Therefore the surface area of a cube is expressed as;

SA = 6l².

This is because a cube has 6 equal faces. The area of each face is given as l². Where l is the side length.

Therefore the surface area of the prism is calculated as;

SA = 6l²

= 6 × 7²

= 6 × 49

= 294yd²

therefore the area of the prism is 294yd²

Given:

The pair of expressions in the options.

To find:

The two expressions are equivalent for any value of y.

Solution:

Two expressions are equivalent for any value of y, iff they are equivalent.

[tex]3(3y+3)=3(3y)+3(3)[/tex]

[tex]3(3y+3)=9y+9[/tex]

Clearly, [tex]3(3y+3)[/tex] is not equivalent to [tex]6y+6[/tex] or [tex]9y+6[/tex]. So, options A and B are incorrect.

[tex]9(y+3)=9(y)+9(3)[/tex]

[tex]9(y+3)=9y+27[/tex]

[tex]9(y+3)=27+9y[/tex]

The expression [tex]9(y+3)[/tex] is not equivalent to [tex]12+9y[/tex]. So, option C is incorrect.

The expression [tex]9(y+3)[/tex] is equivalent to [tex]27+9y[/tex].

Answer:

report me !!! dont ask why or how

Step-by-step explanation:

Answer:

100 percent

Step-by-step explanation:

mean ( average daily demand ) ( d )  = 27 pounds

standard deviation of demand ( std ) = 8 pounds

Lead time ( taken order takes to arrive ) ( L ) = 5 days

Reorder point = 155 pounds

Determine the service level )

Applying the equation below

Reorder point = d x L + (Z x  std )       note : Z = service factor

155 = 27 * 5 + ( Z  * 8 )

155  = 135 + 8Z

hence Z ( service factor ) = ( 155 - 135 ) / 8 = 2.5

hence the service level is ≈ 100 percent

(0.25 ; 21.75)

8.7 (1 decimal place)

Step-by-step explanation:

Net change in scores : X = 6,14,12,23,0

Sample mean, xbar = (6 + 14 + 12 + 23 + 0) /5 = 55 /5 = 11

Sample standard deviation, s = 8.66 ( from calculator)

Sample standard deviation = 8.7( 1 decimal place)

Sample size, n = 5

The 95% confidence interval; we use t, because n is small

Tcritical at 95%, df = 4 - 1 = 3 ; Tcritical = 2.776

Xbar ± standard Error

Standard Error = Tcritical * s/√n

Standard Error = 2.776 * 8.66/√5

Standard Error = 10.751086 = 10.75

Lower boundary = (11 - 10.75) = 0.25

Upper boundary = (11 + 10.75) = 21.75

We need to find the derivative first. Think of x/(x+2) as x(x+2)^(-1). That will allow us to use the product rule. You could also use the quotient rule if you want. I'll go with the product rule route.

[tex]f(x) = \frac{x}{x+2}\\\\f(x) = x(x+2)^{-1}\\\\f'(x) = (x+2)^{-1}-x(x+2)^{-2}\\\\f'(x) = \frac{1}{x+2}-\frac{x}{(x+2)^2}\\\\f'(x) = \frac{x+2}{(x+2)^2}-\frac{x}{(x+2)^2}\\\\f'(x) = \frac{x+2-x}{(x+2)^2}\\\\f'(x) = \frac{2}{(x+2)^2}\\\\f'(x) = \frac{2}{x^2+4x+4}\\\\[/tex]

Since we want the tangent slope to be 1/2, we'll set f ' (x) equal to 1/2 and solve for x.

[tex]f'(x) = \frac{2}{x^2+4x+4}\\\\\frac{1}{2} = \frac{2}{x^2+4x+4}\\\\1*(x^2+4x+4) = 2*2\\\\x^2+4x+4 = 4\\\\x^2+4x = 0\\\\x(x+4) = 0\\\\x = 0 \ \text{ or } \ x+4 = 0\\\\x = 0 \ \text{ or } \ x = -4\\\\[/tex]

The two x values, x = 0 and x = -4, make f ' (x) equal to 1/2.

---------

If x = 0, then y is...

[tex]y = f(x)\\\\f(x) = \frac{x}{x+2}\\\\f(0) = \frac{0}{0+2}\\\\f(0) = 0\\\\[/tex]

Showing that (0,0) is one point we're after.

If x = -4, then,

[tex]y = f(x)\\\\f(x) = \frac{x}{x+2}\\\\f(-4) = \frac{-4}{-4+2}\\\\f(-4) = 2\\\\[/tex]

Making (-4, 2) the other point where the tangent slope is 1/2.

We use the original f(x) function, and not the derivative, when determining the y coordinates of the two points. If you plugged x = 0 or x = -4 into f ' (x), you'd get 1/2. So its good practice, but not what we're after ultimately.
