Answer:

I think it's dilation or none

Step-by-step explanation:

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:

[tex]E=-\$0.47[/tex]

Step-by-step explanation:

From the question we are told that:

Sample size  

Number of Ace [tex]A=4-1=3[/tex]

Number of Face card [tex]F=12[/tex]

Number of other cards [tex]O=36[/tex]  

Generally the Probability of drawing an ace is mathematically given by

[tex]P(A)=\frac{A}{n}\\P(A)=\frac{3}{51}\\P(A)=0.06[/tex]

Generally the Probability of drawing an Face card is mathematically given by

[tex]P(F)=\frac{F}{n}\\P(F)=\frac{12}{51}\\P(F)=0.24[/tex]

Generally the Probability of drawing an Face card is mathematically given by

[tex]P(F)=\frac{F}{n}\\P(F)=\frac{36}{51}\\P(F)=0.71[/tex]

Therefore expected value with one ace removed E

[tex]E=0.06*20+0.24*5-0.71*4[/tex]

[tex]E=-\$0.47[/tex]

The expected value of the game with one ace removed is -0.44 and this can be determined by using the concept of probability.

Given :

So from the deck of the 52 cards number of Ace cards are 3, the number of Face cards are 12 and the other cards are 36.

Drawing an Ace card has a probability of:

[tex]\rm P(A) = \dfrac{A}{n}[/tex]

[tex]\rm P(A) = \dfrac{3}{51}[/tex]

P(A) = 0.06

Drawing a Face card has a probability of:

[tex]\rm P(F) = \dfrac{F}{n}[/tex]

[tex]\rm P(F) = \dfrac{12}{51}[/tex]

P(F) = 0.24

Drawing other cards has a probability of:

[tex]\rm P(O) = \dfrac{O}{n}[/tex]

[tex]\rm P(O) = \dfrac{36}{51}[/tex]

P(O) = 0.71

So, the expected value with one Ace removed is:

[tex]\rm P = 0.06\times 20 + 0.24\times 5 - 0.71 \times 4[/tex]

P = 1.2 + 1.2 - 2.84

P = 2.4 - 2.84

P = -0.44

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

Answer:

[tex]Range = \{4,7,9\}[/tex]

Step-by-step explanation:

Given

The attached function

Required

The range of the function

A function is represented by matching an arrow from the domain to the range.

This implies that, the arrow comes from the domain to the range

From the attached function, the arrow points to 4,7 and 9

Hence, the range is:

[tex]Range = \{4,7,9\}[/tex]

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].

Therefore, the correct option is D.

Answer: (c)

Step-by-step explanation:

Given

A person has a 30% chance of winning a lottery ticket.

Probability of not getting the lottery ticket is 70%

For person to win at fifth ticket, it must fail in first four

So, the probability associated with it is

[tex]\Rightarrow P=(0.70)\times (0.70)\times (0.70)\times (0.70)\times (0.30)\\\\\Rightarrow P=(0.70)^4\cdot (0.3)[/tex]

Hence, option (c) is correct.

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

Answer:

What do I answer?.......

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

Step-by-step explanation:

Answer:74inch

Step-by-step explanation:

Assuming this is a right triangle you do pythogreom theorm and get 74 inches

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.
