Answer: Answer is in the steps read carefully
Step-by-step explanation:
1. y = -3x It has a slope of -3 and y intercept of 0 so it goes with C
2. y =2x+ 5 It has a slope of 2 and y intercept of 5 so it goes with E
3. y = 1/2x - 3 It has a slope of 1/2 and y intercept of -3 so it goes with D
4. y= -1x + 2 It has a slope of -1 and y intercept of 2 so it also goes with A
5. y = 1x It has a slope of 1 and y intercept of 0 so it goes with B
The manufacturer's suggested retail price (MSRP) for a particular car is $25,425, and it is expected to be
worth $11,730 in 5 years.
(a) Find a linear depreciation function for this car.
(b) Estimate the value of the car 7 years from now.
(c) At what rate is the car depreciating?
(a) What is the linear depreciation function for this car?
(Simplify your answer. Do not include the $ symbol in your answer.)
Answer:
(a) The linear depreciation function of the car which gives the worth of the car y after a number of years, t is given as follows;
y = 25,425 - 2,739 × t
(b) The value of the car 7 years from now is $6,252
(c) $2,739 per year
Step-by-step explanation:
The manufacture's suggested retail price (MSRP) for the car = $25,425
The amount the car is expected to be worth in 5 years = $11,730
(a) The linear depreciation is given as follows;
[tex]Depreciation \ Per \ Year \ = \dfrac{Cost \ of \, Asset - Salvage \ Value}{Life \ of \, Asset \ in \ use}[/tex]
Where;
Cost of Asset = $25,425
Salvage Value = $11,730
Life of Asset in use = 5 years
We get;
[tex]Depreciation \ Per \ Year \ = \dfrac{\$ 25,425 - \$11,730}{5} = \$2,739/year[/tex]
Therefore, the linear depreciation function, can be written as follows;
y - 25,425 = -2,739×(t - 0)
y = -2,739·t + 0 + 25,425 = 25,425 -2,739·t
y = 25,425 - 2,739 × t
Where;
y = The expected worth of the car after a given number of years
t = The number of years used for the calculation of the depreciation
(b) The value of the car 7 years from now is given by substitution as follows;
Whet t = 7, we have;
y = 25,425 -2,739·t = y = 25,425 -2,739 × 7 = $6,252
The value of the car 7 years from now = $6,252
(c) [tex]Depreciation \ Per \ Year \ = \dfrac{\$ 25,425 - \$11,730}{5} = \$2,739/year[/tex]
The car is depreciating at a rate of $2,739 per year.

Martha tiene un negocio en el cual vende huevos empacados por docena. Uno de sus clientes le pide solamente 5/6 de docena, ¿cuántos huevos debe venderle Martha?
Answer:
María solamente debe venderle al cliente 10 unidades
Step-by-step explanation:
Explicación paso a paso:
Una docena representa un total de doce (12) unidades. Los huevos se empacan por docena, por lo tanto si nos piden solo 5/6 de la docena, multiplicamos dicha fracción por 12 unidades:
5/6 · 12 = (12 · 5)/6 = 60/6 = 10 unidades
Por lo tanto, María solamente debe venderle al cliente 10 unidades, es decir 5/6 representa 10 unidades de los huevos
Usando conceptos de proporción, se encuentra que Martha debe vender 10 huevos al cliente.
---------------------------
Esta pregunta se resuelve por proporciones, usando una regla de tres.Una docena está compuesta por 12 huevos. ¿cuántos huevos en 5/6 de docena?1 docena - 12 huevos
5/6 de docena - x huevos
Aplicando multiplicación cruzada:
[tex]x = 12 \times \frac{5}{6} = \frac{12 \times 5}{6} = 2 \times 5 = 10[/tex]
Martha debe vender 10 huevos.

The simplified expression for g(f(x)) is 2x.
The simplified expression for g(f(x)) is x.

Answer: 1,4,5
Step-by-step explanation:
The correct options are, The simplified expression for g(f(x)) is x.
The functions are not inverses of each other.
What is an inverse function?First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.
We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.
Given, f(x) = 1/(8x³).
f(x) = 1/(2x)³.
y = 1/(2x)³.
(2x)³ = 1/y.
[tex]2x = \frac{1}{y^\frac{1}{3}}[/tex].
[tex]x = \frac{1}{2y^\frac{1}{3}}[/tex].
[tex]f^{-1}(x) = \frac{1}{2x^\frac{1}{3}}[/tex] and g(x) = [tex]2x^\frac{1}{3}[/tex] so, they are not inverses of each other.
Now, f(g(x)) = [tex]\frac{1}{8((2x)^\frac{1}{3})^3}[/tex].
f(g(x)) = 1/16x.
g(f(x)) = [tex]2(1/8x^3)^\frac{1}{3}[/tex].
g(f(x)) = x

Answer:
46.9333 feet per second
Step-by-step explanation:
A tree is 18 feet tall. A wire runs from the top of the tree to a point 4 feet from its base. The wire is √340 feet long. Estimate the length of the wire to the nearest hundredth of a foot. The wire is about (Blank) feet long.
Answer:
The wire is about 18.44 feet long.
Step-by-step explanation:
From the question:
The wire is √340 feet long.
This implies that the length of the wire is √340 feet.
Converting the value of this length (√340) to decimal gives;
√340 = 18.439
Now, let's convert 18.439 to the nearest hundredth of a foot.
18.439 ≅ 18.44
Therefore, the length of the wire to the nearest hundredth of a foot is 18.44 feet.
In other words, the wire is about 18.44 feet long.

Use the diagram to the right a. What algebraic expression represents GK? b. If GK = 24. what are GH and JK? G H J K a What algebraic expression represents GK? GK (Simplify your answer Do not factor)
Answer:
Step-by-step explanation:
The question lacks appropriate diagram. Find the diagram attached below;
From the diagram GK = GH+HJ+JK
Given GH = GJ-HJ
GH = 2x+2-x
GH = x+2
HJ = x
JK = HK - HJ
JK = 6x-1-x
JK = 5x-1
GK = x+2+x+5x-1
collect like terms
GK = x+x+5x+2-1
GK = 7x+1
Given GK = 24, then;
7x+1 = 24
7x = 24-1
7x= 23
x = 23/7
Since GH = x+2
GH = 23/7 + 2
GH 23+14/7
GH = 37/7
Also JK = 5x-1
JK = 5(23/7)-1
JK = 115/7 - 1
JK = 115-7/7
JK = 108/7
Use area of squares to visualize Pythagorean theorem
The diagram shows a right triangle and three squares. The area of the largest square is 55 units.
Answer:
A. 12 and 43
Step-by-step explanation:
Pythagorean theorem is given as = [tex] a^2 + b^2 = c^2 [/tex]
Where, a and b are the two legs of the right triangle, while c is the hypotenuse/longest leg of the triangle.
In the figure given, the side of the largest square = the hypotenuse of the triangle = c
While the side of the other squares = a and b respectively, of the triangle.
Area of square = s², where s is the side length of the square.
Since we are given that the area of the largest square = 55, this is also equivalent to c² in the Pythagorean theorem.
The side length of the largest square = √55 ≈ 7.4 = c
Therefore, to determine the area of the other squares, check the options given if they add up to give 55.
Option A: 12 + 43 = 55
Option B: 14 + 40 = 54
Option C : 16 + 37 = 53.
The correct possible areas of the smaller squares would be A. 12 and 43.
