The distance between the lines L1 and L2 given by √293/7.

The distance is the angular separation between any two points on one line. Eventually, the smallest distance between these lines is zero. The distance between the lines is the same length as the perpendicular between them.

Finding two locations P1 and P2 on L1 and L2 separately will help us determine the shortest path between them. We then need to project P1P2 in the direction n that is perpendicular to both L1 and L2 to arrive at the answer. To put it another way, L1 - L2 distance = COMPN (P1P2).

Let the two points be

[tex]$$\begin{aligned}& \vec{r}=\hat{1}+2 \hat{j}-4 \hat{k}+\lambda(2 \hat{i}+3 \hat{j}+6 \hat{k}) \\& \vec{r}=3 \hat{i}+3 \hat{j}-5 \hat{k}+\mu(2 \hat{i}+3 \hat{j}+6 \hat{k})\end{aligned}$$[/tex]

To translate a function left or right, you need to shift the graph of the function horizontally. To move the graph to the left, you subtract the same amount from each x-coordinate. To move the graph to the right, you add the same amount to each x-coordinate.

To translate a function left or right, you need to shift the graph of the function horizontally. If you want to move the graph to the left, you need to subtract the same amount from each x-coordinate. This means that all the points on the graph will be shifted to the left by the same amount. For example, if the graph of the function is f(x) = x² and you want to move it left by two units, you need to subtract two from each x-coordinate so the new graph would be f(x) = (x-2)². Similarly, if you want to move the graph right, you need to add the same amount to each x-coordinate. For example, if the graph of the function is f(x) = x² and you want to move it right by three units, you need to add three to each x-coordinate so the new graph would be f(x) = (x+3)².

Step-by-step explanation:

The solution to the system of equations is x = −2, y = ±√23.

Equation is a math statement that expresses two expressions with an equal sign. It is used to find the value of an unknown variable or unknowns. Equations are used in many branches of mathematics and science. For example, equations are used to calculate the force of gravity, the speed of light, the temperature of a gas, and the area of a triangle. Equations are also used to solve problems in physics, chemistry, engineering, and other disciplines. Equations are written in symbols and often involve multiple equations.

This system can be solved by solving the two equations separately.

For the first equation, xe^y+2e^y= 0, we can rearrange it to get xe^y = −2e^y. We can then divide both sides by e^y to get x = −2.

For the second equation, x² − 3x + y² = 19, we can plug in the value of x that we found previously, x = −2, and rearrange the equation to get y² = 23, and then solve for y by taking the square root of both sides, giving y = ±√23.

Therefore, the solution to the system of equations is x = −2, y = ±√23.

This is a linear system since it is a linear combination of the inputs x[n] and x[n-1].

A: y[n] = x[n] x x[n-1]

This is a linear system since it is a linear combination of the inputs x[n] and x[n-1]. We can represent this equation as:

y[n] = a * x[n] + b * x[n-1]

where a and b are constants.

For example, if x[n] = 2 and x[n-1] = 3 then y[n] = 2 x 3 = 6.

C: y[n] = x2[n]

This is also a linear system since it is a linear combination of the input x[n] and its squared value x2[n]. We can represent this equation as:

y[n] = c * x[n] + d * x2[n]

where c and d are constants.

For example, if x[n] = 2 then y[n] = c * 2 + d * 2² = c * 2 + d * 4.

Therefore, the correct answer is D: (a) and (c).

The rank of object according to acceleration from greatest to least is:

C = B > A

In the given question, we have to rank the magnitude of each object's acceleration from greatest to least: Disregard the direction of the accelerations.

The acceleration is given by:

a = [tex]\frac{dv}{dt}[/tex]

where, dv represents change in velocity and dt represents change in time.

Also, Acceleration = slope of velocity - time graph

For object A acceleration is 0 because velocity is constant.

Now for object B:

[tex]a_{B}=\frac{5-0}{10-0}[/tex]

[tex]a_{B}=\frac{5}{10}[/tex]

[tex]a_{B}=\frac{1}{2}[/tex]

[tex]a_{B}[/tex] = 0.5 m/s square

Now for the object C:

[tex]a_{C}=\frac{-5-0}{10-0}[/tex]

[tex]a_{C}=-\frac{5}{10}[/tex]

[tex]a_{C}=-\frac{1}{2}[/tex]

[tex]a_{C}[/tex] = -0.5 m/s square

As we know that magnitude cannot be negative, so

[tex]a_{C}[/tex] = 0.5 m/s square

As we can see that acceleration of object B and C is same although the acceleration of object A is 0 which is smaller than the acceleration of B and C.

So the rank of object according to acceleration from greatest to least is:

Answer:

(a)  5/12

Step-by-step explanation:

to solve this problem you can make all fractions equivalent with 12 as the denominator

a) 5/12

b) 2/3 = 8/12      Multiply top and bottom by 4

c) 5/6 = 10/12     Multiply top and bottom by 2

d) 3/4 = 9/12       Multiply top and bottom by 3

if you compare numerators, the smallest one is the closest to zero, which would be (a) 5/12

Answer:

A 5/12

Step-by-step explanation:

first you need to round these all to /12 so a is 5/12

12/3 is 4 so multiply 4 by two which means b is 8/12

12/6 is 2 so multiply 5 by two which gives us c = 10/12

12/4 is 3 and multiply 3 x 3 which is 9 so d is 9/12

5 is the lowest decimal/fraction which makes it the closest to 0

After calculating the average of his last 4 years’ salaries and will give him 1. 9% of that average for each year he worked, the total pension is $2928.204.

In the given question, we have to calculate Henry pension.

Henry has worked for a factor for 31 years and will be retiring.

He earned salaries over the past 4 years of $38433, $37776, $39125, and $38782.

His employer calculates pension by finding the average of his last 4 years’ salaries and will give him 1.9% of that average for each year he worked.

His earning over the past 4 years = $38433, $37776, $39125, $38782

The average of Henry earning = Sum of his earning over 4 years / number of years

The average of Henry earning = ($38433 + $37776 + $39125 + $38782)/4

The average of Henry earning = $154,116/4

The average of Henry earning = $38,529

Hence, the average of Henry last 4 years’ salaries is $38,529.

The pension is 1.9% of the average salary. So,

Pension = $38,529×1.9%

Pension = $38,529×0.019

Pension = $732.051

He worked for total 4 years. So,

Total pension = $732.051×4

Total pension = $2928.204

Dividend: The number that is being divided.

Divisor: The number by which the dividend is being divided.

Quotient: The result of the division, which is the number of times the divisor can "fit into" the dividend.

Remainder: The amount left over after the division is complete. It is the part of the dividend that is not "fit" into the divisor.

The front door is twice as long as the bedroom door.

A bedroom door in the house has the same dimensions and length and all at the front door. The length is 30 in rather than 63. If the bedroom door has a length of 30 inches, and the front door has the same dimensions but is longer, we can compare the two lengths using a proportion.

We can write the proportion as 30 inches / x inches = 1/2, where x is the length of the front door. To find the length of the front door, we can cross-multiply and solve for x: x = 30 inches * 2 = 60 inches. So the front door is 60 inches long, which is twice as long as the bedroom door.

The linear equation with a fraction in it can be solved by using y-intercept form method.

What are linear equations?

A linear equation is one in which the variable's maximum power is always 1. A one-degree equation is another name for it. A linear equation in one variable has the conventional form Ax + B = 0. In this equation, x is a variable, A is a coefficient, and B is constant. A linear equation in two variables has the conventional form Ax + By = C. The variables x and y are variables, the coefficients A and B are coefficients, and the constant C is a constant.

Now,

y-intercept form-

Make sure the linear equation is in the form y = mx + b. This is called the y-intercept form, and it's probably the easiest form to use to graph linear equations. The values in the equation do not need to be whole numbers. Often you'll see an equation that looks like this: y = 1/4x + 5, where 1/4 is m and 5 is b.[1]

m is called the "slope," or sometimes "gradient."[2] Slope is defined as rise over run, or the change in y over the change in x.

b is defined as the "y-intercept." The y-intercept is the point at which the line crosses the Y-axis.[3]

x and y are both variables. You can solve for a specific value of x, for example, if you have a y point and know the m and b values. x, however, is never merely one value: its value changes as you go up or down the line.
