Find the shortest distance between the line L1 passing through the points A =
(3,2,1) and B = (2,1,0) and the line L2 passing through the points C = (2,4,−1) and
D = (3,0,−2)
The shortest distance between the two skew lines is equal to 11√38 / 38 units.
How to find the shortest distance between two skew lines in space
According to linear algebra, lines are defined by vectorial equations of the form:
(x, y, z) = P(x, y, z) + t · T(x, y, z)
Where:
P(x, y, z) - Point contained in the line.t - Parameter.T(x, y, z) - Vector slope.And the shortest distance between two skew lines is determined by the following expression:
[tex]d = \frac {|[P_{2} (x, y, z) - P_{1}(x, y, z)] \bullet [T_{1} (x, y, z) \times T_{2} (x, y, z)]|}{|T_{1} (x, y, z) \times T_{2} (x, y, z)|}[/tex]
First, determine the points contained in each line:
P₁(x, y, z) = (3, 2, 1)
P₂(x, y, z) = (2, 4, - 1)
Second, find each vector slope:
T₁(x, y, z) = (2, 1, 0) - (3, 2, 1)
T₁(x, y, z) = (- 1, - 1, - 1)
T₂(x, y, z) = (3, 0, - 2) - (2, 4, - 1)
T₂(x, y, z) = (1, - 4, - 1)
Third, determine the vector subtraction:
P₂(x, y, z) - P₁(x, y, z) = (2, 4, - 1) - (3, 2, 1)
P₂(x, y, z) - P₁(x, y, z) = (- 1, 2, - 2)
Fourth, determine the cross product:
T₁(x, y, z) × T₂(x, y, z) = (- 1, - 1, - 1) × (1, - 4, - 1)
T₁(x, y, z) × T₂(x, y, z) = (- 3, - 2, 5)
Fifth, use the dot product:
[tex][P_{2} (x, y, z) - P_{1}(x, y, z)] \bullet [T_{1} (x, y, z) \times T_{2} (x, y, z)] = (- 1, 2, - 2) \,\bullet\,(- 3, - 2, 5)[/tex]
[tex][P_{2} (x, y, z) - P_{1}(x, y, z)] \bullet [T_{1} (x, y, z) \times T_{2} (x, y, z)] = 3 - 4 - 10[/tex]
[tex][P_{2} (x, y, z) - P_{1}(x, y, z)] \bullet [T_{1} (x, y, z) \times T_{2} (x, y, z)] = - 11[/tex]
Sixth, calculate the norm of the cross product:
|T₁(x, y, z) × T₂(x, y, z)| = √[(- 3)² + (- 2)² + 5²]
|T₁(x, y, z) × T₂(x, y, z)| = √38
Finally, determine the shortest distance between the two skew lines:
d = |- 11| / √38
d = 11 / √38
d = 11√38 / 38

y = x - 11
7x+7y=-21
systems of equations by substitution
Answer: We can solve the system of equations using the substitution method.
First, we'll isolate "y" in one of the equations and substitute it into the other equation:
Y = x - 11
7x + 7y = -21
Substituting the first equation into the second equation:
7x + 7(x - 11) = -21
7x + 7x - 77 = -21
14x = 56
x = 4
Now that we have found the value of x, we can substitute it back into one of the original equations to find the value of y:
Y = x - 11
Y = 4 - 11
Y = -7
The solution to the system of equations is (x, y) = (4, -7).
Step-by-step explanation:
The value of x and y in the equation is 4 and -7 respectively
What is Simultaneous equation?Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. For example, below are some simultaneous equations: 2x + 4y = 14 4x − 4y = 4.
Using substitution method to solve the system,
y = x-11 equation 1
7x+7y = -21 equation 2
substitute x-11 for y in equation 2
7x + 7( x-11) = -21
7x + 7x -77 = -21
14x = -21+77
14x = 56
divide both sides by 14
x = 56/14
x = 4
substitute 4 for x in equation 1
y = 4-11
y = -7
therefore the value of x and y is 4 and -7 respectively

The effective annual rate (EAR) is the actual rate of interest that is earned or paid over a given period of time, taking into account the compounding of interest. For example, a stated rate of 7.80% with 4 compounding periods per year would result in an EAR of 15.30%.
The effective annual rate (EAR) is a measure of the actual rate of interest that is earned or paid over a given period of time. It takes into account the effect of compounding, which is the process of earning interest on both the principal and the accumulated interest. This means that the rate of return can increase over time. The EAR is calculated by taking the stated rate of interest, which is the rate of interest stated by the lender, and multiplying it by the number of compounding periods per year. For example, if the stated rate is 7.80% and the compounding periods per year are 4, then the EAR would be 15.30%. Similarly, if the stated rate is 12.40% and the compounding periods per year are 365, then the EAR would be 11.40%. If the compounding period is infinite, then the EAR will be the same as the stated rate, in this case 12.40%. Therefore, the EAR is the actual rate of return that is earned or paid over a given period of time.

Consider a market characterized by the following inverse demand and supply functions: PX = 50 − 4QX and PX = 10 + 2QX. Compute the surplus producers receive when a $30 per unit price floor is imposed on the market.
A $75
B $35
C $25
D $50
Computing the surplus producers receive when a $30 per unit price floor is imposed on the market is option C.$25.
How did we get the value?To calculate the surplus producers receive, we need to find the difference between the price they receive at a given quantity and the price they would have received in the absence of the price floor.
When a price floor of $30 per unit is imposed on the market, the quantity supplied and demanded at this price are:
QX = (50 - 30)/4 = 5 units (demand)
QX = (30 - 10)/2 = 10 units (supply)
So, the surplus received by the producers is the difference between the price floor and the price they would have received in the absence of the price floor:
Surplus = 30 - (10 + 2 * 10) = 30 - 30 = $0.
However, the surplus for consumers is the difference between the price they would have paid in the absence of the price floor and the price floor:
Surplus = (50 - 4 * 5) - 30 = 25 - 30 = -$5.
So, the total surplus received by producers and consumers combined is $0 + (-$5) = -$5, which means that the price floor imposes a dead weight loss on the market.

Since the linear map ⟨⋅,x−w⟩ is constantly 0 on the basis of W, it is constantly zero on all of W, hence x−w∈W⊥.
But then, since x∈(W⊥)⊥, we have ⟨x−w,x⟩=0, and since ⟨x−w,w⟩=0,
∥x−w∥2=⟨x,x−w⟩−⟨w,x−w⟩=0,
i.e. x=w∈W, completing the proof.
2 ) Suppose that w∈(W⊥)⊥
then ⟨w,x⟩=0
for all x∈W⊥
If w∉W, then w=v+v′ where v∈W and v′∈W⊥∖{0}.
Then.
0=⟨w,x⟩=⟨v,x⟩+⟨v′,x⟩=⟨v′,x⟩
for all x∈W⊥.
However, v′∈W⊥ and ⟨v′,v′⟩≠0 so it is a contradiction.

If you want to solve the equation by completing the square, then rearrange the equation as x2−6x=11 and add 9 to each side. If you want to solve the equation by using the quadratic formula, rearrange the equation as x2−6x−11=0 and substitute the values of 1, −6 , and −11 into the formula. Round to the nearest hundredth.
Solution of equation x² - 6x = 11 are, x = 7.47 and x = - 1.47
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The equation is,
⇒ x² - 6x = 11
Now, Solve the equation by completing the square as,
⇒ x² - 6x = 11
Add 9 both side, we get;
⇒ x² - 6x + 9 = 11 + 9
⇒ (x - 3)² = 20
⇒ x - 3 = √20
⇒ x - 3 = ± 4.47
This gives two solutions,
⇒ x - 3 = 4.47
⇒ x = 4.47 + 3
⇒ x = 7.47
⇒ x - 3 = - 4.47
⇒ x = - 4.47 + 3
⇒ x = - 1.47
Thus, Solution of equation x² - 6x = 11 are,
⇒ x = 7.47 and x = - 1.47

A city planner designs a park that is a quadrilateral with vertices at J(−3, 1), K(3, 3), L(5, −1), and M(−1, −3). There is an entrance to the park at the midpoint of each side of the park. A straight path connects each entrance to the entrance on the opposite side. Assuming each unit of the coordinate plane represents 10 meters, what is the total length of the paths to the nearest meter? Round your answer to the nearest whole number.
Answer: To determine the length of the paths connecting the entrance to the opposite entrance, we first need to find the midpoint of each side of the park. Then, we will use the distance formula to calculate the distance between each pair of midpoints.
Let's begin by finding the midpoint of each side of the park.
JK: (-3 + 3, 1 + 3) / 2 = (0, 2)
KL: (3 + 5, 3 - 1) / 2 = (4, 2)
LM: (5 - 1, -1 - -3) / 2 = (2, -2)
MJ: (-1 + -3, -3 + 1) / 2 = (-2, -1)
Next, we'll use the distance formula to calculate the distance between each pair of midpoints.
JK: sqrt((4 - 0)^2 + (2 - 2)^2) = sqrt(16 + 0) = 4
KL: sqrt((2 - 4)^2 + (-2 - 2)^2) = sqrt(16 + 16) = 4 sqrt(2)
LM: sqrt((-2 - 2)^2 + (-1 + 2)^2) = sqrt(16 + 9) = sqrt(25) = 5
MJ: sqrt((-2 - 0)^2 + (-1 - 2)^2) = sqrt(4 + 9) = sqrt(13)
The total length of the paths is 4 + 4 sqrt(2) + 5 + sqrt(13), which when rounded to the nearest whole number is 14.
