The vector x = [2, -3, 1] is a basis for Row(A)⊥. This means that any vector in Row(A)⊥ can be written as a multiple of x.
To find a basis for Row(A)⊥ using the dot product, we need to find a vector that is orthogonal to all the rows of A. This means that the dot product of the vector and each row of A should be equal to 0.
Let's say the vector we are looking for is x = [x1, x2, x3]. Then we need to solve the following system of equations:
x1 * 1 + x2 * 4 + x3 * 2 = 0
x1 * 2 + x2 * 2 + x3 * 1 = 0
x1 * 3 + x2 * 1 + x3 * 1 = 0
We can write this system of equations in matrix form as:
[1 4 2] [x1] = [0]
[2 2 1] [x2] = [0]
[3 1 1] [x3] = [0]
We can use Gaussian elimination to solve this system of equations. After performing the necessary row operations, we get:
[1 0 -2] [x1] = [0]
[0 1 3] [x2] = [0]
[0 0 0] [x3] = [0]
From the last equation, we can see that x3 can be any value. Let's choose x3 = 1. Then, from the second equation, we get x2 = -3, and from the first equation, we get x1 = 2.
So, the vector x = [2, -3, 1] is a basis for Row(A)⊥. This means that any vector in Row(A)⊥ can be written as a multiple of x.

Sidney measured a summer camp and made a scale drawing. The sand volleyball court is 3 centimeters wide in the drawing. The actual volleyball court is 9 meters wide. What scale did Sidney use for the drawing?
The scale factor that Sidney used for the drawing is approximately 0.00333.
To determine the scale that Sidney utilised for the drawing, we can put up a proportion. The ratio will compare the drawing's shown volleyball court's width to the actual court's width:
Scale factor = width in drawing / real width
The scaling factor will be x. Next, we have:
3 cm / 900 cm = x
By multiplying 9 metres by 100, we may convert them to centimetres:
9 metres equals 9 times 100, or 900 centimetres.
By condensing the proportion, we obtain:
x = 0.00333
Thus, Sidney utilised a scale factor for the drawing that is roughly 0.00333. As a result, each centimetre on the drawing corresponds to 0.00333 metres, or 3.33 millimetres, on the volleyball court in real life.

Answer:
it means if the given sides are approximately equal then the triangles are equal too
Step-by-step explanation:
if the the sides are equal then the triangles are equal too
Two of the vertices of a triangle are located at (6,0) and (5,10) on the coordinate plane. The third vertex is located at (x,20), where x is a negative value. The area of the triangle is 60 square units
The missing vertex is located at (-14,20).
To find the missing vertex, let's assume that the third vertex is located at (x,20) and the coordinates of the other two vertices are (6,0) and (5,10). Then the coordinates of the two sides of the triangle are:
Side AB: (6,0) to (5,10)
Side AC: (6,0) to (x,20)
Using the formula for the area of a triangle, which is:
Area = 1/2 * base * height
Where the base is one of the sides of the triangle and the height is the perpendicular distance from the third vertex to the base, we can set up an equation to solve for x:
60 = 1/2 * |(6-5)*20 - (x-6)*10|
60 = 1/2 * |200 - 10x + 60|
120 = |260 - 10x|
120 = 10x - 260 or 120 = -(10x - 260)
x = -14 or x = -2
Since x has to be a negative value, the missing vertex is located at (-14,20). Therefore, the three vertices of the triangle are:
A = (6,0)
B = (5,10)
C = (-14,20)
We can verify that the area of the triangle with these vertices is indeed 60 square units using the same formula:
Area = 1/2 * |(6-5)(20-10) - (-14-6)(20-0)|
Area = 1/2 * |10 - (-400)|
Area = 1/2 * 410
Area = 205 square units
Therefore, the missing vertex is located at (-14,20).

Find all the values of b that will make the trinomial 3x^(2)-bx+12 factorable? Choose one value of b and factor the resulting trinomial.
To find all the values of b that will make the trinomial 3x^(2)-bx+12 factorable, we need to use the discriminant of the quadratic formula. The discriminant is the part of the quadratic formula under the square root: b^(2)-4ac. If the discriminant is a perfect square, then the trinomial will be factorable.
So we plug in the values of a, b, and c from the trinomial: b^(2)-4(3)(12) = b^(2)-144.
We want this to be a perfect square, so we can set it equal to a perfect square and solve for b:
b^(2)-144 = 36
b^(2) = 180
b = sqrt(180)
b = 6sqrt(5)
So one value of b that will make the trinomial factorable is 6sqrt(5).
Now we can plug this value of b back into the trinomial and factor it:
3x^(2)-6sqrt(5)x+12 = 0
(3x-6)(x-sqrt(5)) = 0
So the factors of the trinomial are (3x-6) and (x-sqrt(5)).

Show that the given set is an infinite set by placing it in a one-to-one correspondence with a proper subset of itself. (Use n as your variable. ) B = {11, 15, 19, 23, 27, 31, , 4n + 7, } Let F = {15, 19, 23, 27,
Set B, which contains the elements 11, 15, 19, 23, 27, 31, 4n+7 and so on, is an infinite set because there exists a one-to-one correspondence between set B and a proper subset of itself, namely set F, which contains the odd integers greater than or equal to 15.
To expose that set b is infinite, we want to set up a one-to-one correspondence among set B and A proper subset of itself. Allow F to be the set of odd integers greater than or equal to 15, i. E., F = {15, 19, 23, 27, ...}.We are able to outline a characteristic f from set b to set f as follows:
f(11) = 15
f(15) = 19
f(19) = 23
f(23) = 27
f(27) = 31
f(4n+7) = 4(n+2) + 3
the first five factors of set b are mapped to the primary 5 factors of set f. For any detail 4n+7 in set b, the corresponding detail in set f is 4(n+2)+3, which is the next peculiar integer after 4n+7. It may be shown that this function is a one-to-one correspondence between set b and set f.
Consequently, given that set f is a proper subset of set b and there exists a one-to-one correspondence among them, set b should be infinite.

Note that the ALEKS.graphing calculator can be used to make computations easier. First mechanie: s1 per hour Second mechanic: $ per hour ?
The rate charged per hour by the first mechanic and the second mechanic.
The total number of hours worked by the two mechanics is 10 hours + 15 hours = <<10+15=25>>25 hours. The total amount charged by the two mechanics is $2400. If we let x be the rate charged per hour by the first mechanic, and y be the rate charged per hour by the second mechanic, we can write the following equations:
x + y = 195 (the sum of the two rates is $195 per hour)
10x + 15y = 2400 (the total amount charged is $2400)
We can use the first equation to solve for one of the variables in terms of the other. For example, we can solve for y in terms of x:
y = 195 - x
We can then substitute this expression for y into the second equation:
10x + 15(195 - x) = 2400
Simplifying this equation gives us:
10x + 2925 - 15x = 2400
-5x = -525
x = 105
We can then substitute this value of x back into the first equation to find the value of y:
105 + y = 195
y = 90
Therefore, the rate charged per hour by the first mechanic is $105 per hour, and the rate charged per hour by the second mechanic is $90 per hour.

The highest value assumed by the loop counter in a correct "for statement" with the given header is (b) 70.
The "for-statement" is ⇒for(i = 7; i <= 72; i += 7) ,
The loop starts with i = 7 and increases by 7 in each iteration until i becomes greater than 72.
So we can find the highest value of "i" assumed by the loop counter by solving the inequality i <= 72 for i.
⇒ i <= 72
Starting with i = 7 and increasing by 7 in each iteration,
We have,
⇒ i = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77
The last value of i in the sequence, 77, is greater than 72, so the loop counter stops before reaching 77.
So, the highest value assumed by the loop counter in this for statement is : 70.
Therefore, the highest value assumed by the loop counter is (b) 70.

It's going up in tens so it must start from 5, therefore the one between 25 and 45 must be 35.
The bearing of p from q is 312°, what is the bearing of q from p
As per the difference concept, the bearing of Q from P is 132°.
To find the bearing of Q from P, we need to calculate the difference between the bearing of P from Q and 180 degrees. This is because the bearing from P to Q is the opposite direction of the bearing from Q to P.
Let's use some notation to make this clearer. Let the bearing from P to Q be denoted by B(PQ), and the bearing from Q to P be denoted by B(QP). We are given that B(PQ) = 312°. To find B(QP), we use the following formula:
B(QP) = B(PQ) - 180°
We know that B(PQ) is 312°, so we can substitute this value into the formula to get:
B(QP) = 312° - 180°
B(QP) = 132°

First, answer Part A. Then, answer Part B. to scive -x^(2)+3x+14=-(1)/(4)x^(2)+5 ystem into the bin labeled System Solutions.
Using quadratic formula we get, Part A: The solutions for x are: x = (3 + √(57))/(3/2) and x = (3 - √(57))/(3/2). Part B: The first system solution is: ((3 + √(57))/(3/2), -(76 + 6√(57))/(9) + 5) and second system solution is: ((3 - √(57))/(3/2), -(76 - 6√(57))/(9) + 5)
Part A: To solve for x, we need to first rearrange the equation so that all terms are on one side of the equal sign. Adding (1/4)x^(2) to both sides of the equation:
-x^(2) + (1/4)x^(2) + 3x + 14 = 5
Next, combining like terms:
-(3/4)x^(2) + 3x + 14 = 5
Now, subtracting 5 from both sides:
-(3/4)x^(2) + 3x + 9 = 0
Finally, using quadratic formula to solve for x:
x = (-3 ± √(3^(2) - 4(-3/4)(9)))/(2(-3/4))
Simplifying:
x = (-3 ± √(57))/(2(-3/4))
x = (-3 ± √(57))/(-3/2)
x = (3 ± √(57))/(3/2)
Part B: To determine the system solutions, we need to plug in the values of x into the original equation and solve for y. For the first solution:
y = -(1/4)((3 + √(57))/(3/2))^(2) + 5
y = -(1/4)((9 + 6√(57) + 57)/(9/4)) + 5
y = -(1/4)((76 + 6√(57))/(9/4)) + 5
y = -(19 + (3/2)√(57))/(9/4) + 5
y = -(76 + 6√(57))/(9) + 5
For the second solution:
y = -(1/4)((3 - √(57))/(3/2))^(2) + 5
y = -(1/4)((9 - 6√(57) + 57)/(9/4)) + 5
y = -(1/4)((76 - 6√(57))/(9/4)) + 5
y = -(19 - (3/2)√(57))/(9/4) + 5
y = -(76 - 6√(57))/(9) + 5

A person places $8290 in an investment account earning an annual rate of 6%, compounded continuously. Using the formula =V=Pe^rt, where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 12 years.
Step-by-step explanation:
Using the formula V = Pe^(rt), where P is the principal initially invested, e is the base of a natural logarithm, r is the rate of interest, and t is the time in years:
V = Pe^(rt)
We are given that P = $8290, r = 0.06 (since the annual interest rate is 6%), and t = 12 (since we want to find the value of the account after 12 years). Therefore, we can plug in these values and solve for V:
V = 8290 * e^(0.06*12)
V = 8290 * e^(0.72)
V = $17,936.34
Therefore, the amount of money in the account after 12 years, to the nearest cent, is $17,936.34.

Step-by-step explanation:
I just asked this question but completely forgot to mention the main focus of the project. I need to solve this word problem using three ways. Substitution, Elimination, and Graphing. "The state fair is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 8 vans and 8 buses with 240 students. High School B rented and filled 4 vans and 1 bus with 54 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and bus."
Answer:
Let's first define our variables:
Let x be the number of students in each van and bus.
Using substitution:
From the problem, we know that:
High School A rented 8 vans and 8 buses, with a total of 240 students. So we can write the equation:
8x + 8x = 240
High School B rented 4 vans and 1 bus, with a total of 54 students. So we can write the equation:
4x + 1x = 54
Now, we can solve for x in one of the equations and then substitute that value into the other equation to solve for the other variable. For example, let's solve for x in the second equation:
5x = 54
x = 10.8
Now, we can substitute this value of x into the first equation to solve for the number of students in each van and bus for High School A:
8x + 8x = 240
8(10.8) + 8(10.8) = 172.8
So each van and bus for High School A has 10.8 students in it.
Using elimination:
We can rewrite the equations we used above in standard form:
8x + 8y = 240
4x + y = 54
We can eliminate y by multiplying the second equation by -8 and adding it to the first equation:
8x + 8y = 240
-32x - 8y = -432
-24x = -192
x = 8
Now, we can substitute this value of x into either equation to solve for y:
4(8) + y = 54
y = 22
So each van and bus for High School A has 8 students in it and each van and bus for High School B has 22 students in it.
Using graphing:
We can graph the two equations on the same coordinate plane and find the point where they intersect, which represents the solution:
8x + 8y = 240
4x + y = 54
To graph these equations, we can first solve for y in each equation:
y = -x + 30
y = -4x + 54
Then, we can plot these two lines on the same coordinate plane and find their intersection:
(6, 24)
So each van and bus for High School A has 6 students in it and each van and bus for High School B has 24 students in it.

Surveying Property A surveyor locating the corners of a triangular piece of property started at one corner and walked 480 ft in the direction of N36°W to reach the next corner. The surveyor turned and walked S21°W to get to the next corner of the property. Finally, the surveyor walked in the direction N82°E to get back to the starting point. What is the area of the property in square feet?
The area of the triangular piece of property is approximately 63,121.75 square feet.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Starting at the first corner, the surveyor walks 480 ft in the direction N36°W. We can break this down into its northward and westward components:
Northward component = 480 cos(36°)
≈ 388.75 ft
Westward component = 480 sin(36°)
≈ 295.42 ft
This takes the surveyor to the second corner of the property.
From the second corner, the surveyor walks S21°W to get to the third corner. We can again break this down into its southward and westward components:
Southward component = 480 cos(21°)
≈ 435.89 ft
Westward component = 480 sin(21°)
≈ 168.75 ft
Finally, the surveyor walks N82°E to get back to the starting point.
We can break this down into its northward and eastward components:
Northward component = 388.75 ft
Eastward component = 435.89 sin(82°)
≈ 426.04 ft
Now we have the lengths of all three sides of the triangular property:
Side 1 = 480 ft
Side 2 = √[(295.42 - (-168.75))^2 + (388.75 - 435.89)^2]
≈ 421.66 ft
Side 3 = √[(426.04 - 295.42)^2 + (388.75 - 0)^2]
≈ 296.13 ft
calculate the area of the triangular property, we can use Heron's formula:
Area = √[s(s - a)(s - b)(s - c)]
where s is the semiperimeter (half the perimeter) of the triangle,
and a, b, and c are the lengths of its sides.
s = (480 + 421.66 + 296.13)/2 ≈ 598.40
Area = √[598.40(598.40 - 480)(598.40 - 421.66)(598.40 - 296.13)]
Area ≈ 63,121.75 sq ft
Therefore, the area of the triangular piece of property is approximately 63,121.75 square feet.
