Matt sells used books on the internet. The cost of using the website is $7.50 per week and he earns 1.50 on each book he sells Matt uses the linear model y=1.5x to figure his weekly earnings what is the rate of Change of this situation
Answer:
$1.5 per book
Step-by-step explanation:
Since y=1.5x, the rate of change is 1.5/1. Rate of change: y/x. Hence, the rate of change is 1.5/1 since y=1.5 and x=1.
1.5 / 1 = 1.5
Hence, the rate of change is 1.5.
But what's 1.5 represent?
1.5 is the number of dollars earned per book sold.
Hence, the rate of change is $1.5 per book.

What is variables?
Any qualities, quantity, or number that can be gauged or tallied qualifies as a variable. A data item is another name for a variable. Examples of variables include age, sex, company income and expenses, country of birth, capital expenditures, class grades, eye color, and vehicle kind.
The joint p.d.f of X and Y is f(x, y)
f(x,y) = cxy/ 1+[tex]x^{2}[/tex]+[tex]y^{2}[/tex] for 0 < x < 1 and 0 < y < 1

Take substitute 1+[tex]x^{2}[/tex]+ [tex]y^{2}[/tex] = t⇒2y dy=dt
Lower limit: y = 0⇒t=1+[tex]x^{2}[/tex]
Upper limit: y=1➡t=1+[tex]x^{2}[/tex]+1
F(x) = cx/2

=cx/2 (In (1+[tex]x^{2}[/tex]+1/1+[tex]x^{2}[/tex]))
=Cx (In(1+1/1+[tex]x^{2}[/tex]))

Take substitute 1 + [tex]y^{2}[/tex] + [tex]x^{2}[/tex] = t 2x dx = dt
Lower limit: x = 0
t = 1 + [tex]y^{2}[/tex]
Upper limit: x =1
=t + [tex]y^{2}[/tex] + 1
F(y)=cy/2({1x=0 2x/1+[tex]y^{2}[/tex]+[tex]x^{2}[/tex]/dx)

=cy(In(1+[tex]y^{2}[/tex]+1/1+[tex]y^{2}[/tex]))
=cy/2(In(1+1/1+y2))
Now we have to check for independence.
F(x,y)= cxy/1+[tex]x^{2}[/tex]+[tex]x^{2}[/tex] for0<x<1 and 0<y<1
F(x) = cx/2( In(1+1/1+[tex]x^{2}[/tex])) for 0<x<1
F(y)=cy/2(In(1+1/1+[tex]y^{2}[/tex])) for < y <1
=f(x)*f(y)
=c2xy/4 ( In ( 1+1/1+[tex]x^{2}[/tex] ) *In( 1+1/1+[tex]y^{2}[/tex])) #f(x,y)
F(x,y) #f(x)* f(y) for all x and y
=x and y are not independent.

Geometry Dilation
Please help!!!!
Answer:
C' (-2, -2)
D' (-2, 2)
E' (2, 0)
F' (0, -2)
Step-by-step explanation:
A dilation of factor k about the origin is a transformation that enlarges a figure by a factor of k, while keeping the origin fixed.
It means that each point (x, y) on the pre-image is transformed to a new point (kx, ky) in the dilated figure.
Therefore, the rule for a dilation of 2 about the origin is:
(x, y) → (2x, 2y)From inspection of the given diagram, the vertices of the pre-image are:
C = (-1, -1)D = (-1, 1)E = (1, 0)F = (0, -1)Applying the dilation rule (x, y) → (2x, 2y):
C' = (2 · -1, 2 · -1) = (-2, -2)D' = (2 · -1, 2 · 1) = (-2, 2)E' = (2 · 1, 2 · 0) = (2, 0)F' = (2 · 0, 2 · -1) = (0, -2)Work out

suppose winston's loud music externalizes a cost onto his neighbor, chloe. suppose winston and chloe decide to solve this problem using the coase theorem. if they are successful, what is a possible result of the execution of this theorem?
The Coase theorem states that if property rights are well-defined and transaction costs are low, then the allocation of resources will be efficient, regardless of the initial allocation of property rights.
If Winston and Chloe successfully apply the Coase theorem to solve the problem of Winston's loud music externalizing a cost onto Chloe, they may reach a mutually beneficial agreement. This could result in either Winston reducing the volume of his music or compensating Chloe for the cost of the externalization, or a combination of both.
The goal is to reach a solution where the costs and benefits are more efficiently allocated between the two parties.

The fractions found in the 2/n table in the Rhind Mathematical Papyrus.
2/7 = (m n 2 ) 1 n (m n 2 )
= (2 7 2 ) 1 7 (2 7 2 )
= (14 2 ) 1 7 (14 2 )
= 7 1 7 + 7 1 14
2/35 = (m n 2 ) 1 n (m n 2 )
= (2 35 2 ) 1 35 (2 35 2 )
= (70 2 ) 1 35 (70 2 )
= 35 1 35 + 35 1 70
2/91 = (m n 2 ) 1 n (m n 2 )

formulas used to calculate the free cash flow to firm (fcff)?
(OCF): OCF = Net Income + Depreciation & Amortization - Changes in Working Capital, (CapEx): CapEx = Investment in Property, Plant & Equipment + Investment in Intangible Assets. therefore, (FCFF): FCFF = OCF - CapEx
The Free Cash Flow to Firm (FCFF) is a measure of a company’s cash flow available for distribution to shareholders and debt holders. To calculate FCFF, the following three steps are taken:
1. Calculate Operating Cash Flow (OCF): OCF is calculated by taking net income, adding back depreciation and amortization, and subtracting any changes in working capital.
2. Calculate Capital Expenditures (CapEx): CapEx includes investments in property, plant, and equipment, as well as any investments in intangible assets.
3. Calculate Free Cash Flow to Firm (FCFF): FCFF is calculated by subtracting CapEx from OCF. This figure represents the cash flow available for distribution to shareholders and debt holders.

The probability that vertex b will be the bottom vertex will be 1/16
The ant has four equally likely possibilities for his initial step from the top vertex, each heading to one of the four vertices close to the top vertex.
When the ant reaches vertex A, he has four equally likely next steps, each heading to one of the vertices next to vertex A.
Only one of these possibilities, however, will send him to the bottom vertex: the one that brings him straight to the bottom vertex.

Suppose that 15 inches of wire costs 75 cents.
At the same rate, how much (in cents) will 9 inches of wire cost?
Answer: 45 cents.
Step-by-step explanation: We can find the cost per inch of wire by dividing the total cost by the total length of wire:
75 cents / 15 inches = 5 cents/inch
Now that we know the cost per inch, we can find the cost of 9 inches of wire by multiplying the cost per inch by 9:
5 cents/inch * 9 inches = 45 cents.
Answer:45 cents for 9 inches of wire
Step-by-step explanation:
Per every 5 incheses is 0.25 cents 0.75/15=$0.25 and then taking 0.25/5=$0.05 cents. So 1 inch costs 0.05 cents. So multiply 0.05×9=$0.45 cents. 45 cents

What is triangle?A triangle is a three-sided polygon with three angles. It is one of the basic shapes in geometry and is very versatile as it can be used to create many other shapes and structures. Triangles are generally classified by the length of their sides, which can be equal (an equilateral triangle), longer in one side than the other two sides (an isosceles triangle) or different in length on all three sides (a scalene triangle). They can also be classified by their angles, which can be acute (the angles are all less than 90 degrees), right (one angle is exactly 90 degrees) or obtuse (one angle is greater than 90 degrees).
x = 63.8°
Using the Law of Cosines, we can calculate the value of x:
x² = 17² + 9² - 2(17)(9)cos(90°)
x² = 289 + 81 - 306
x² = 64
x = √64

list five vectors in span{1, 2 }. for each vector, show the weights on 1 and 2 used to generate the vector. do not make a sketch. V1 = ( 3 1 2 ) , V2 = ( −4 0 1 )
The five vectors in the span {v1, v2} are (0 0 0), (3 1 2), (-4 0 1), (-1 1 3) and (7 1 1)
We are given that two vectors
v1 = ( 3 1 2 ) and v2 = ( −4 0 1 )
We have to list five vectors in the span {v1, v2}
Let us choose five sets of weights as:
w = {0, 0}, {1, 0}, {0, 1}, {1, 1}, {1, -1}
So, the five vectors are:
V1 = 0 (v1) + 0 (v2) = (0 0 0)
V2 = 1 (v1) + 0 (v2) = (3 1 2)
V3 = 0 (v1) + 1 (v2) = (-4 0 1)
V4 = 1 (v1) + 1 (v2) = (3-4 1+0 2+1) = (-1 1 3)
V5 = 1 (v1) - 1 (v2) = (3+4 1-0 2-1) = (7 1 1)
Hence, the five vectors in the span {v1, v2} are (0 0 0), (3 1 2), (-4 0 1), (-1 1 3) and (7 1 1)

how to show that the real exponetial sequence for f[k]=f[kt] is f[k]b^k
The real exponential sequence for f[k]=f[kt] is f[k]=b^k.
What is exponential sequence ?
The exponential function is a mathematical function denoted by f(x)=\exp or e^{x}. Unless otherwise specified, the term generally refers to the positive-valued function of a real variable, although it can be extended to the complex numbers.
The real exponential sequence for f[k]=f[kt] can be shown to be f[k]=b^k by using the definition of exponential functions. If f[k]=f[kt], then f[k]=f[k-1]t and f[k-1]=f[k-2]t, and so on. By substitution, we have:
f[k]=f[k-1]t
f[k-1]=f[k-2]t
f[2]=f[1]t
f[1]=f[0]t
So we can write:
f[k]=f[k-1]t=f[k-2]t^2=...=f[1]t^(k-1)=f[0]t^k
Next, we can define b as f[0] and substitute it into the above equation:
f[k]=b^k
Therefore, the real exponential sequence for f[k]=f[kt] is f[k]=b^k.

The volume of a cone = (1/3) πr2h cubic units
Therefore, the volume of a cone = 20.93 cubic units
What is cone and formula?A cone has only one face, which is the circular base but no edges. A cone has only one apex or vertex point. The volume of the cone is ⅓ πr2h. The total surface area of the cone is πr(l + r) The slant height of the cone is √(r2+h2)Basically, the volume is equal to the product of the area and height of the shape. Volume = Base Area x Height. For shapes having flat surfaces such as cubes and cuboids, it is easy to find the volumeTo calculate the volume of a box, you need to know its height, width, and depth. You can find the volume by multiplying these three dimensions togetherTo learn more about cone refers to:
