Final answer:
With the imposition of a $30 tax on dog sitting, Rebecca and Susan would both be worse off by the combined surplus of $25 they initially had without the tax, as the tax exceeds the surplus and disrupts the transaction.
Explanation:
The question involves the impact of a tax on a market transaction between Rebecca and Susan, who had initially agreed upon a price for dog sitting. Initially, without the tax, the surplus for Rebecca would be the difference between what she values the service at ($200) and the agreed price ($185), which is $15. For Susan, the surplus is the difference between the agreed price ($185) and her minimum acceptable price ($175), which is $10. This results in a combined surplus of $25. When a $30 tax is imposed, it is likely that they will share the burden of the tax, but without specifics on how the tax is divided, we will consider it fully affects either party. If the full tax falls on Susan, she would receive $155 ($185 - $30), which is less than her minimum price of $175; thus, she would no longer agree to dog sit. If Rebecca bears the entire tax, she would effectively be paying $215 ($185 + $30), which is more than her valuation of $200, and she would not agree to the transaction. Regardless, the transaction would not occur due to the tax, making both parties worse off by the surplus they would have gained, which is the combined $25.

Option C is correct, y=4x-6 is the equation of the line that is parallel to the first line and passes through the point (1, –2)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
A line passes through the origin and has a slope of 4

What is the remainder when 314^162 is divided by 7?
Final answer:
To find the remainder of 314162 divided by 7, we use modular arithmetic and find that the powers of 314 mod 7 repeat every 3 powers. Since 162 is a multiple of 3, 314162 mod 7 equals 1.
Explanation:
The question asks for the remainder when 314162 is divided by 7. To solve this problem, we can use a concept known as modular arithmetic, which deals with the remainder upon division. The key here is to find a pattern in the powers of 314 modulo 7, because large numbers can be cumbersome to work with directly. A helpful property is that (a×b) mod n = [(a mod n)×(b mod n)] mod n.
Let's consider the powers of 314 mod 7:
3141 mod 7 = 2
3142 mod 7 = (314 × 314) mod 7 = (2 × 2) mod 7 = 4
3143 mod 7 = (3142 × 314) mod 7 = (4 × 2) mod 7 = 1
Since we reached 1 again, the sequence will repeat every 3 powers. Now, 162 is divisible by 3 (162 = 3 × 54). Therefore, we can conclude that 314162 mod 7 will have the same remainder as 3143 mod 7, which is 1.

(1) the area of a rectangle with vertices at (−6, 3) , (−3, 6) , (1, 2) , and (−2, −1)
To find area of rectangle we need to find the length and width
Length = distance between (−6, 3) and (−2, −1)
Distance = [tex]\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]
= [tex]\sqrt{(-2-(-6))^2 + (-1-3)^2}[/tex]
= [tex]\sqrt{(4)^2 + (-4)^2}[/tex]=[tex]\sqrt{(16) + 16}[/tex] =[tex]\sqrt{32}[/tex]
width = Distance between (−6, 3) , (−3, 6)
Distance = [tex]\sqrt{(-3-(-6))^2 + (6-3)^2}[/tex]
=[tex]\sqrt{3^2+3^2}= \sqrt{18}[/tex]
Area = Length * width = [tex]\sqrt{32} *\sqrt{18} = \sqrt{576}= 24[/tex]
(2) the area of a triangle with vertices at (0, −2) , (8, −2) , and (9, 1)
Area of triangle = [tex]\frac{1}{2} * base * height[/tex]
base is the distance between (0,-2) and (8,-2)
Distance = [tex]\sqrt{(8-0)^2 + (-2-(-2))^2}[/tex] = 8
To find out height we take two vertices (8,-2) and (9,1)
Height is the change in y values = 1- (-2) = 3
base = 8 and height = 3
So area of triangle = [tex]\frac{1}{2} * 8 * 3 = 12[/tex]
(3) the perimeter of a polygon with vertices at (−2, 1) , (−2, 4) , (2, 7) , (6, 4) , and (6, 1)
To find perimeter we add the length of all the sides
Distance between (−2, 1) and (−2, 4) = [tex]\sqrt{(-2+2)^2 + (4-1)^2}[/tex]= 3
Distance between(−2, 4) and (2, 7) = [tex]\sqrt{(2+2)^2 + (7-4)^2}[/tex]= 5
Distance between (2, 7) and (6, 4) = [tex]\sqrt{(6 - 2)^2 + (4-7)^2}[/tex]= 5
Distance between (6, 4) and (6, 1) = [tex]\sqrt{(6 - 6)^2 + (1-4)^2}[/tex]= 3
Distance between (6, 1) and (−2, 1) = [tex]\sqrt{(-2-6)^2 + (1-1)^2}[/tex]= 8
Perimeter = 3 + 5 + 5 + 3 + 8 = 24
(4) four coordinates are (-7,-1) (-6,4) (3,-3) and (4,2)
Length = Distance between (3,-3) and (4,2) = [tex]\sqrt{(4-3)^2 + (2+3)^2}[/tex]= [tex]\sqrt{26}[/tex]
Width = Distance between (-6,4) and (4,2) = [tex]\sqrt{(4+6)^2 + (2-4)^2}[/tex]= [tex]\sqrt{104}[/tex]
Perimeter = 2(lenght + width) = 2*( [tex]\sqrt{26}[/tex]+[tex]\sqrt{104}[/tex] )
= 30.6 units

1. According to the question, the vertices of the rectagle are at [tex](-6, 3) ;(-3, 6) ;(1, 2)[/tex] , and [tex](-2, -1)[/tex].
The distance between two vertices on the coordinate plane is
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
So,
[tex]Length=D_1\\D_1=\sqrt{(6-3)^2+(-3+6)^2}\\D_1=\sqrt{9+9}\\D_1=3\sqrt 2 units[/tex]
Similarly,
[tex]Width=D_2\\D_2=\sqrt{(-2+6)^2+(-1-3)^2}\\D_2=\sqrt{16+16}\\D_2=16\sqrt 2\;units[/tex]
The area of the rectangle is equals to product of length and width of the rectabgle.
So,
[tex]Area=length\times width\\Area=3\sqrt{2}\times 4\sqrt{2}\\Area=24\;square\;units[/tex]
Hence, the area of the rectangle is [tex]24\;square\;units[/tex].

A pattern for 1 1 uniform uses 12 12 yards of material. Boleslaw wants to know how many yards are needed for 8 8 uniforms. Chantal wants to know how many yards she will need to make 15 15 uniforms.
To find the amount of material needed for a certain number of uniforms, we can use a proportion and multiply the amount of material needed for 1 uniform by the desired number of uniforms.
Explanation:To find out how many yards are needed for 8 uniforms, we can set up a proportional relationship between the number of uniforms and the amount of material needed. We can do this by dividing the amount of material needed for 1 uniform by the number of uniforms, and then multiplying by the desired number of uniforms. The formula for this is (Amount of material needed for 1 uniform / Number of uniforms) * Desired number of uniforms. Using this formula, we can determine that 8 uniforms would require (12 yards / 1 uniform) * 8 uniforms = 96 yards of material.
To find out how many yards are needed for 15 uniforms, we can use the same formula. (12 yards / 1 uniform) * 15 uniforms = 180 yards of material.
Therefore, 8 uniforms require 96 yards of material, and 15 uniforms require 180 yards of material.

Find the velocity, v(t), for an object moving along the x-axis if the acceleration, a(t), is a(t) = 3t^2 + cos(t) and v(0) = 2.
v(t) = t^3 + sin(t) + 2
v(t) = t^3 - sin(t) + 3
v(t) = 6t - sin(t) + 2
v(t) = t^3 - sin(t) + 2
The velocity function of an object moving along the {x} - axis would be -
v{t} = sin(t) + t³ + 2.
What is instantaneous acceleration?The acceleration at any instant of time is called instantaneous acceleration. Mathematically -
a = dv/dt
dv = a dt
∫dv = ∫a dt
Given is the acceleration function as -
a(t) = 3t² + cos(t)
We know that -
a = dv/dt
dv = a dt
∫dv = ∫a dt
v{t} = ∫{3t² + cos(t)} dt
v(t) = sin(t) + t³ + C
Now -
v(0) = 2
sin(0) + 0 + C = 2
C = 2
So, we can write the velocity function as -
v{t} = sin(t) + t³ + 2
Therefore, the velocity function of an object moving along the {x} - axis would be -
v{t} = sin(t) + t³ + 2.
