The argument is valid by the law of detachment.

The statements that are true about the arguments in the question are;

1) Option C; Law of detachment

2) Option B; Law of detachment

1) We are given the premise that;

If two lines are parallel, then the lines do not intersect.

This premise is true because we know from parallel and perpendicular lines property that parallel lines never intersect each other.

With that premise, we are now given a conclusion that; Lines m and n do not intersect.

This kind of condition is known as law of detachment which states that;

If x is true, then y is also true.

Thus, Option C is correct

2) We are given the premise that;

If a quadrilateral is a square, then the quadrilateral has four right angles.

The given premise is true because from the definition of a square, all sides must be equal and all angles must be right angles.

We are now given the conclusion that;

Quadrilateral JKLM has four right angles.

This conclusion is valid because it follows the given premise.

Again like in 1 above, this follows the law of detachment.

Answer:

0.34 miles per minute

Step-by-step explanation:

We have to convert 30 feet per second to miles per minute.

1 minute = 60 seconds

Therefore, in one minute = 60 × 30 = 1800 feet

5280 feet = 1 mile

180 feet =  [tex]\frac{1800}{5280}[/tex]

              = 0.3409 ≈ 0.34 mile

Therefore, 0.34 mile per minute.

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)

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

y=4x is the equation of the line.

We have to find the equation of the line that is parallel to the first line and passes through the point (1, –2)

Slope is 4 as it is parallel.

We have to find the y intercept

Answer: y = 3x - 2

Step-by-step explanation:

Equation of a straight line is

y=mx + c

m is the slope and c is the intercept

comparing it with the equation

y=3x - 2

m = slope =3

and c= intercept= -2

To make m the subject of the equation x-2m=p, add 2m to both sides, subtract p, and divide by 2. The result is m as the subject of the equation, represented as the fraction (x - p)/2.

To solve the equation x-2m=p for m as the subject, we want to isolate m on one side of the equation. Here is the step-by-step process:

Now m is the subject of the equation, and it is represented as a fraction as requested.

Step-by-step explanation:

(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

The area of the rectangle is [tex]24\;square\;units[/tex].

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].

An equation is formed when two equal expressions. The number of merchandise that you would have to purchase in a year to pay the same amount under both plans is 800.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that you are choosing between two plans at a discount warehouse.

The cost for x number of merchandise under plan A, which offers an annual membership fee of $120 and you pay 80% of the manufacturer's. Therefore, the cost will be,

Cost = 120 + 0.8x

The cost for x number of merchandise under plan B, which offers an annual membership fee of $40 and you pay 90% of the manufacturer's recommended list price. Therefore, the cost will be,

Cost = 40 + 0.9x

Now, in order to find the number of merchandise that you would have to purchase in a year to pay the same amount under both plans, you need to equate the two equations together. Therefore,

Cost from Plan A = Cost from Plan B

120 + 0.8x = 40 + 0.9x

120 - 40 = 0.9x - 0.8x

80 = 0.1x

x = 80 / 0.1

x = 800

Hence, the number of merchandise that you would have to purchase in a year to pay the same amount under both plans is 800.

Further, the cost for each plan for 800 merchandise can be written as,

PlanA,

Cost = 120 + 0.8(800)

        = $760

Plan B,

Cost = 40 + 0.9(800)

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.
