A more modern explanation would be, "Parallel lines are two lines within a given plane that never intersect."

Two lines on a sphere are an illustration that defies the notion of parallel lines. Meridians are the name given to longitude lines on spheres like the Earth.

Meridians are lines that run parallel to one another from the North Pole to the South Pole. However, if we take into account two meridian lines, they will cross at the North and South Poles. Two lines that are originally parallel will, therefore, eventually intersect at the poles on a sphere, defying the notion of parallel lines.

We can change the original definition of parallel lines to read, "Parallel lines are two lines that do not intersect within a given plane."

This adjustment accounts for the fact that lines can exist in many geometrical contexts, such as on a sphere or in three-dimensional space, where the idea of parallelism may be different. By including the phrase "within a given plane," we restrict the concept to the typical geometry seen in Euclidean geometry, where parallel lines do not meet.

A newer definition may therefore read, "Parallel lines are two lines within a given plane that never intersect." This updated definition makes clear that parallel lines must be taken into account inside a certain plane in order to maintain their validity, while also acknowledging the limitations of the idea.

The speed of the carts after collision is  3 m/s.

We have to note that in this case, we would need to apply the principle of the conservation of linear momentum. This implies that the momentum before collision would have to be the same as the momentum after collision.

Then we have;

Momentum before collision = Momentum after collision thus;

(3 * 4) + ( 1 * 0) = (3 + 1) v

Note that the two carts are said to stick together and move with a common speed

Hence;

12 = 4v

v = 12/4

v = 3 m/s

Answer:

2x-3y<-9

Step-by-step explanation:

Answer:

Step-by-step explanation:

Area = L * W

L = 1/2

Area = 5/16

5/16 = 1/2 * w    You could do this using decimals

5/16 = 0.3125

1/2 = 0.5

0.3125 = 0.5 * w

w = 0.3125/0.5

w = 0.625

w = 5/8

The other way is done by fractions

\(\frac{\frac{5}{16} }{\frac{1}{2} } = \frac{5}{16}*\frac{2}{1} =\frac{5}{8}\)

Answer:

The vertex of the function is at (–3,–16)

The graph is increasing on the interval x > –3

The graph is positive only on the intervals where x < –7 and where

x > 1.

Step-by-step explanation:

The graph of \(f(x)=(x-1)(x+7)\) has clear zeroes at \(x=1\) and \(x=-7\), showing that \(f(x) > 0\) when \(x < -7\) and \(x > 1\). To determine where the vertex is, we can complete the square:

\(f(x)=(x-1)(x+7)\\y=x^2+6x-7\\y+16=x^2+6x-7+16\\y+16=x^2+6x+9\\y+16=(x+3)^2\\y=(x+3)^2-16\)

So, we can see the vertex is (-3,-16), meaning that where \(x > -3\), the function will be increasing on that interval

Step-by-step explanation:

The two numbers chosen or plotted by them are:

-75 and 75

Step-by-step explanation:

It is given that Bernita and Derek each plot a number on a number line with the properties:

1. The two numbers they have plotted are unique or different.

2. Also there absolute value is same.

3. The sum of the absolute values of the numbers is 150.

We know that Absolute value of a positive number is a number itself and absolute value of a negative number is it's inverse.

So the two numbers that satisfy the above three properties are:

-75 and 75.

Formula for calculating slope can also be used in finding the rate of change of the given graph above.

Rate of change = \( \frac{y_2 - y_1}{x_2 - x_1} \)

Take the coordinates of any two points on the graph. Let make use of (2, 9) and (4, 18).

Thus,

Rate of change = \( \frac{18 - 9}{4 - 2} = \frac{9}{2} = 4.5 \)

Rate of change demonstrated in the graph is 4.5 miles per hour.

The english phrase "Seven less than four times a number" as an algebraic expression is 4x - 7

From the question, we have the following parameters that can be used in our computation:

seven less than four times a number

Represent the number with x

So:

four times a number means 4x

So, we have

seven less than 4x

seven less than means - 7

So, we have

4x - 7

Hence, the english phrase as an algebraic expression is 4x - 7

Seven less than four times a number

Answer:

  11, 18

Step-by-step explanation:

Let x and y represent the two integers.

  y = 2x -4 . . . . . one is 4 less than twice the other

  x^2 +y^2 = 445 . . . . the sum of their squares is 445

Substituting for y using the first equation, you have ...

  x^2 +(2x -4)^2 = 445

  5x^2 -16x -429 = 0 . . . . . collect terms, subtract 445

  (5x +39)(x -11) = 0 . . . . . . factor*

The positive solution is the value of x that makes a factor zero:

  x = 11

  y = 2(11) -4 = 18

The two integers are 11 and 18.

_____

* The factoring is greatly aided by the knowledge that x=11 is a solution, found using the graphing calculator.

Answer:

64

Step by step solution:

Not exactly sure what it means to expand the product. But to solve, you always do what's in the paranthesis first. So 2 x 4 = 8. The little number 2 means squared or to the power of, which bascially means you multiply the number by how ever many it tells you. So since it says 8 to the power of 2, you just multiply 8 x 8 which equals 64.
