What happens if 0 is one of the coordinates?

The line y = 0 will be having an infinite number of x-intercepts thus a line can cross the x-axis infinite times.

A line section that can connect two places is referred to as a segment.

The line extends endlessly in both directions.

A line segment is just part of a big line that is straight and going unlimited in both directions.

If two lines intersect each other at a point then the number of intersections will be only one,

It is because the line away from the intersection goes away with the line.

But if two lines are on each other having an infinite number of intersections.

For example the intersection of line y = 0 with the x-axis.

Hence "The line y = 0 will be having an infinite number of x-intercepts thus a line can cross the x-axis infinite times".

Answer:

Percentage of decrease in Sales = 11.04% or 11 %

Step-by-step explanation:

Decrease Percentage = [(Original Value - New Value) ÷ Original Value] × 100 

Percentage = [(145,000 - 129,000) ÷ 145,000] × 100

Percentage = [(16,000) ÷ 145,000] × 100

Percentage = (0.1104) × 100

Percentage of decrease in Sales = 11.04% or 11 %

Answer:

a) Q = 0 or 9

b) Q = 5

c) Q = 7

d) Q = 8

Step-by-step explanation:

We assume the postal money order to be of the United State. A smudged digit is calculated using the following algorithm.

1. Add first 10 digits of 11-digit number.

2. Divide the sum of the 10 numbers by 9.

3.The remainder is the smudged digit.

4.The smudged digit is appended to the end of the ID number or anywhere in the number.

It is calculated as:

[tex]x_{11} = (x_{1} + x_{2} + x_{3} + x_{4} + x_{5} + x_{6} + x_{7} + x_{8} + x_{9} + x_{10} )mod 9[/tex]

a) 493212Q0688

[tex]8 = (4 + 9 + 3 + 2 + 1 + 2 + Q + 0 + 6 + 8) mod 9\\8 = (Q + 35) mod 9\\8 = Q mod 9 + 35 mod 9\\8 = Q mod 9 + 8\\Q mod 9 = 8 - 8\\Q mod 9 = 0\\Q = 0 or 9[/tex]

Therefore, Q is either 0 or 9.

b) 850Q9103858

[tex]8 = (8 + 5 + 0 + Q + 9 + 1 + 0 + 3 + 8 + 5) mod 9\\8 = (Q + 39) mod 9\\8 = Q mod 9 + 39 mod 9\\8 = Q mod 9 + 3\\Q mod 9 = 8 - 3\\Q mod 9 = 5\\Q = 5[/tex]

Therefore, Q is 5 because from Q mod 9 = 5, we have Q = 5 mod 9.

c) 2Q941007734

[tex]4 = (2 + Q + 9 + 4 + 1 + 0 + 0 + 7 + 7 + 3) mod 9\\4 = (Q + 33) mod 9\\4 = Q mod 9 + 33 mod 9\\4 = Q mod 9 + 6\\Q mod 9 = 4 - 6\\Q mod 9 = -2\\Q = -2 mod 9\\Q = 7[/tex]

Therefore, Q is 7 because we have to cancel out the negative sign by adding the modulo base (9) to the negative number: -2 + 9 = 7.

d) 66687Q03201

[tex]1 = (6 + 6 + 6 + 8 + 7 + Q + 0 + 3 + 2 + 0) mod 9\\1 = (Q + 38) mod 9\\1 = Q mod 9 + 38 mod 9\\1 = Q mod 9 + 2\\Q mod 9 = 1 - 2\\Q mod 9 = -1\\Q = -1 mod 9\\Q = 8[/tex]

Therefore, Q is 8 because we have to cancel out the negative sign by adding the modulo base (9) to the negative number: -1 + 9 = 8.

For the given postal money order scenarios, the smudged digit, Q, is determined as follows: Scenario a - either 0 or 9, Scenario b - 5, Scenario c - 5, and Scenario d - 3.

Let's analyze the given postal money order scenarios and determine the smudged digit, Q, using the provided algorithm:

Scenario a:

ID number: 493212Q0688

Sum of the first 10 digits: 4 + 9 + 3 + 2 + 1 + 2 + 0 + 6 + 8 + 8 = 43

43 divided by 9 equals 4 with a remainder of 7.

Therefore, the smudged digit, Q, is either 0 or 9.

Scenario b:

ID number: 850Q9103858

Sum of the first 10 digits: 8 + 5 + 0 + 9 + 1 + 0 + 3 + 8 + 5 + 8 = 47

47 divided by 9 equals 5 with a remainder of 2.

Therefore, the smudged digit, Q, is 5.

Scenario c:

ID number: 2Q941007734

Sum of the first 10 digits: 2 + 7 + 9 + 4 + 1 + 0 + 0 + 7 + 7 + 3 = 40

40 divided by 9 equals 4 with a remainder of 4.

To cancel out the negative sign in the remainder, we add the modulo base (9) to the negative number: -4 + 9 = 5.

Therefore, the smudged digit, Q, is 5.

Scenario d:

ID number: 66687Q03201

Sum of the first 10 digits: 6 + 6 + 6 + 8 + 7 + 0 + 3 + 2 + 0 + 1 = 33

33 divided by 9 equals 3 with a remainder of 6.

To cancel out the negative sign in the remainder, we add the modulo base (9) to the negative number: -6 + 9 = 3.

Therefore, the smudged digit, Q, is 3.

Answer:

y = 4x

Step-by-step explanation:

Given that y and x vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition that x = 2, y = 8

8 = 2k ( divide both sides by 2 )

4 = k, thus

y = 4x ← equation of variation

Answer:

3.06 megawatts

Step-by-step explanation:

Firstly, we write the proportionality equation.

wind power varies directly as the square of the length r of one of the blades;

P ∝ r^2

Let’s introduce a constant of proportionality k; This means;

P = kr^2

Now let’s calculate the value of k when 1.5 megawatts and r is 35m

1.5 mw = 35^2 * k

k = 1.5/35^2 = 1.5/1225 = 0.001224489796 MW/m^2

Now we want to calculate the amount of megawatts to be produced by a turbine with 50m blades.

That would be;

P = 0.001224489796 * 50^2 = 3.06 megawatts

Answer:

Step-by-step explanation:

If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.

Given that P varies directly with r², if we introduce a constant of proportionality, k, the expression becomes

P = kr²

If P = 1.5 when r = 35, then

1.5 = k × 35²

k = 1.5/35² = 1.5/1225

Therefore, the direct variation function is

P = 1.5r²/1225

When r = 50, then

P = 1.5 × 50²/1225

P = 3.06 megawatt

Step-by-step explanation:

Before we start to deal with the ratio, we need all lengths in the same units.

The width is 18 inches.

The height is 2 feet.

Let's convert the height to inches. Then we will have both dimensions in the same units, inches.

2 ft * (12 in.)/ft = 24 in.

Now we have:

width = 18 in.

height = 24 in.

ratio of width to height = 18 in. to 24 in. = 18/24 = 3/4 = 3:4

Answer: 5.2752

Well, whenever you are working with fractions with different denominators, you would multiply both the top and the bottom of the fraction with the smaller number as the denominator. (You could also divide the larger denominator number.) So let's see what number we can multiply by 5 to get 10. That would be 2. Then we would multiply the numerator by two as well. So what is 3 times 2? 6. Once you've done that, you get 6/10 or 0.6 in decimal form. The difference would be 0.3 or 3/10. :)

Step-by-step explanation:

Answer:

y = 15x

11x + y = 286

where

y = number of miles driven by the truck driver

x = number of hours the truck driver drives

Solving this gives, x = 11 hours and y = 165 miles.

Step-by-step explanation:

Let the number of hours the truck driver drives be x.

Let the number of miles driven by the truck driver be y.

Since the truck driver drives at 15 miles per hour, the number of miles covered by the driver y, can be given from the speed equation.

Speed = (distance/time)

15 = (y/x)

y = 15x.

And the drivers are paid $11 per hour of driving and also has an expense of $1 per mile driven for gas and maintenance.

Meaning that on a day that the truck driver drives y miles for x hours, the total pay, C, is given as

C = 11x + 1y = 11x + y

So, on this fateful day, the total amount paid to a truck driver was $286

So, C = $286

11x + y = 286.

So, the two equations for the scenarios are

y = 15x

11x + y = 286

Solving this gives, x = 11 hours and y = 165 miles.

Hope this Helps!!!

The system of a linear equation that could be used to determine the number of hours the driver worked and the number of miles the truck drove is : (11x + y = 286) and (y = 15x).

Given :

The following steps can be used in order to determine the system of linear equations:

Step 1 - Let the total number of miles be 'x' and the total number of hours be 'y'.

Step 2 - The linear equation that represents the total expenses for the driver, gas, and truck maintenance is given by:

11x + y = 286

Step 3 - The linear equation that represents the situation that the driver drove an average of 15 miles per hour is given by:

y = 15x

So, the system of a linear equation that could be used to determine the number of hours the driver worked and the number of miles the truck drove is : (11x + y = 286) and (y = 15x).

Final answer:

The possible side lengths for a cubic aquarium that can hold between 4096 cubic inches and 8000 cubic inches of water are between 16 inches and 20 inches.

Explanation:

To find the possible side lengths of an aquarium in the shape of a cube that holds between 4096 cubic inches and 8000 cubic inches of water, you need to find the cube root of each volume since the volume of a cube is V = s³, where s is the side length.

For the minimum volume (4096 cubic inches):
[tex]\sqrt[3]{4096}[/tex] = 16 inches.

For the maximum volume (8000 cubic inches):

[tex]\sqrt[3]{8000}[/tex] = 20 inches.

Hence, the side lengths of the aquarium must be between 16 inches and 20 inches.

Answer:

1. 23.55 in

2. 102.36 mm

Step-by-step explanation:

The circumference of a circle is calculated by the formula: [tex]C=\pi d=2\pi r[/tex] , where d is the diameter and r is the radius.

We can use this to answer both problems.

1. Since the diameter is 7.5 inches, then d = 7.5. Substitute this into the equation: [tex]C=\pi *7.5=3.14*7.5=23.55[/tex]. So, the circumference is 23.55 inches.

2. Here, the radius is 16.3 mm, so r = 16.3. Substitute this into the equation: [tex]C=2\pi r=2*3.14*16.3=102.364=102.36[/tex]. So, the circumference is 102.36 mm.

Hope this helps!

Answer:

1) 23.55 inches

2) 102.36 mm

Step-by-step explanation:

C = pi × d

1) C = 3.14 × 7.5

C = 2 × pi × r

2) C = 2 × 3.14 × 16.3

= 102.364 mm

Answer:

[tex]\frac{21}{4}[/tex]

Step-by-step explanation:

So to start, you need to make 3 [tex]\frac{3}{4\\}[/tex] into an improper fraction, which will give you [tex]\frac{15}{4}[/tex]. Then to make it easier, instead of dividing it by [tex]\frac{5}{7}[/tex], multiply it by the reciprocal ( [tex]\frac{7}{5}[/tex] )

Your new expression should look like this:

    [tex]\frac{15}{4}[/tex] x [tex]\frac{7}{5}[/tex]

To make it even easier, you can simplify this expression even further. Looking at the numerators and denominators, we see that we have a 15 on top and a 5 on the bottom. Cross out the 5 and put a 1 in its place since 5 goes into 5 one time! Now we have to do it to the 15... Cross out the 15 and put a 3 since 5 goes into 15 three times!

Your simplified expression should look like this:

    [tex]\frac{3}{4}[/tex] x [tex]\frac{7}{1}[/tex]

Now, just multiply the numerators and the denominators to get your final answer of

    [tex]\frac{21}{4}[/tex]

Since you cannot simplify this anymore, that is your answer!!!

Answer: 18π units³ or 56.52 units³

Step-by-step explanation: Notice that the figure shown here is a cylinder. To find the volume of a cylinder, start with the formula for the volume of a cylinder which is shown below.

Volume = πr²h

Here, notice that our cylinder has a radius

of 3 units and a height of 2 units.

So we have (π)(3 units)²(2 units).

Start by simplifying the exponent.

(3 units)² is (3 units)(3 units) or 9 units².

So we have (π)(9 units²)(2 units).

Now, (9 units)²(2 units) is 18 units³.

So we have 18π units³.

So the volume of the cylinder shows here is 18π units³.

Remember that π is approximately equal to 22/7 or 3.14. So we can estimate the value of the volume by plugging in 3.14 for π.

So we have (18)(3.14) which is equal to 56.52.

So the value of the volume is approximately 56.52 units³.
