The undefined terms line and plane are needed to precisely define which mathematical term?
line segment
perpendicular lines
parallel lines
ray

Answers

Answer 1

The correct answer is:

parallel lines  

Explanation:

Parallel lines are two lines in a plane that never intersect.  This means the definition uses the undefined terms "line" and "plane."

Answer 2

The undefined terms line and plane are needed to precisely define which mathematical term will be parallel lines so option (C) will be correct.

What are a line and plane?

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

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

A plane is a surface that is straight in nature a plane has a certain area but in most cases.

We know that parallel line are those lines which not intersect and lies on a plane.

Hence there are two things that are needed first is a line and the second is a plane the plane should be single for both lines not different.

Find g (2w) when g(x) = x^2 - 2x + 1

Answers

g(2w)=(2w)²-2(2w)+1
g(2w)=4w²-4w+1

The value of g (2w) is,

g (2w) = 4w² + 4w + 1

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

The given function is;

g(x) = x² - 2x + 1

Now, The value of g (2w) is calculated as;

g(x) = x² - 2x + 1

Put x = 2w in above equation,

g (2w) = (2w)² + 2 (2w) + 1

g (2w) = 4w² + 4w + 1

Hence, The value of g (2w) is ( 4w² + 4w + 1 ).

So, The value of g (2w) is,

⇒ g (2w) = 4w² + 4w + 1

How far can you get away from your little brother with the squirt gun filled with paint if you can travel 3m/s and you have 15s before he sees you?

Answers

Answer:

45 m

Step-by-step explanation:

We are given that a little brother of your with the squirt gun filled with paint  is far away from you.

We have to find the distance between you and your brother

Speed =3 m/s

Time taken by you =15 s

We know that speed=[tex]\frac{distance}{time}[/tex]

Substitute the value then we get

[tex]3=\frac{distance}{15}[/tex]

Distance =[tex]3\times 15[/tex]

Distance =45 m

Hence, you can travel 45 m then he sees you.

Final answer:

You can get 45 meters away from your little brother with the squirt gun filled with paint.

Explanation:

To determine how far you can get away from your little brother with the squirt gun filled with paint, we need to calculate the distance using the formula: distance = speed x time. Given that your speed is 3 m/s and you have 15 seconds before he sees you, the distance can be calculated as follows:

distance = 3 m/s x 15 s = 45 meters

Therefore, you can get 45 meters away from your little brother with the squirt gun filled with paint.

A train travels 220 miles in 4 hours. What is the train's speed in feet per minute?
55 ft/min
4840 ft/min
11 ft/min
660 ft/min

Answers

To work out speed you use the speed, distance and time formula: This is speed = distance/time.

You then need to convert the 220 miles into feet, you times the miles by 5280:
220 * 5280 = 1161600ft

Then you do hours into minuets, you times the hours by 60;
4 * 60 = 240mins

Then you place it into the formula:
1161600ft/240mins = 4840 ft/min

Hope this helps! :)

If A train travels 220 miles in 4 hours. Then train's speed in feet per minute is 4840.

What is speed?

Speed is the time rate at which an object is moving along a path,

To work out speed you use the speed, distance and time formula:

This is speed = distance/time.

Let us convert 220 miles into feet,

1 mile=5280 ft.

So 220 miles

=220×5280

=1161600 ft

Then we convert 4 hours into minuets

4 * 60 = 240mins

now plug in the formula with time and distance .

1161600ft/240mins = 4840 ft/min

Hence  4840 ft/min is the speed of train in feet per minute.

A good one is. 9+10 = 21
r + (-6) = -10

To solve the equation r + (-6) = -10, since -6 is being added to r, we need to subtract -6 from both sides of the equation.

It's important to understand that minus a negative means the same thing as plus a positive so we're really adding 6.

On the left side of the equation, the -6 and +6 cancel out and we have r. On the right side of the equation, -10 + 6 is -4.

So we have r = -4 which is the solution to our equation.

Use the distance formula and simply substitute in the corresponding orders pairs.

Distance = √(x2 - x1)² + (y2 - y1)²

Distance = √(4 - (-6))² + (3 - (-1))²

Distance = √(10)² + (4)²

Distance = √100 + 16

Distance = √116

A video store offers two types of rental cars. Each rental card is good for six months. The gold rental card costs $25 plus $1.75/rental. The silver rental card cost $10 plus $3.25/rental. Explain why someone would prefer one card over the other.

Answers

Final answer:

When choosing between the gold and silver rental cards, it is important to consider the frequency of movie rentals and the associated costs.

Explanation:

When deciding between the gold and silver rental cards, there are a few factors to consider.

The gold rental card has an initial cost of $25 and then charges $1.75 per rental. On the other hand, the silver rental card has an initial cost of $10 and charges $3.25 per rental.

If you rent movies frequently, the silver card may be a better option because even though it has a higher initial cost, the lower charge per rental will result in lower overall cost. However, if you don't rent movies often, the gold card may be a better choice because the lower per-rental cost will offset the higher initial cost.

Let x be the first factor in an expression in scientific notation. Describe the possible values of x.

Answers

Final answer:

In scientific notation, the coefficient is a number from 1 to 10 multiplied by a power of 10, which represents the number of decimal places moved to convert a number to this format.

Explanation:

The first factor in an expression in scientific notation is the coefficient, which must be a number equal to or greater than 1 and less than 10. The coefficient is then multiplied by a power of 10 to represent the original number accurately.

For example, to write the number 79,345 in scientific notation, one would express it as 7.9345 × 104, because we have moved the decimal place to make 79,345 into 7.9345 while recording that we have moved the decimal place four positions to the right, hence the power of 10 being 4.

Well, first, 10 to the 5th power is 100,000. So, it can calculate 100,000 per second. The question asks how many calculations can it perform in 10 seconds, so you are going to do 100,000x10. Your answer should be 1,000,000. So, it can calculate 1,000,000 in 10 seconds!

Answer:

Computer can do the calculations = [tex]10^{6}[/tex] in 10 seconds

Step-by-step explanation:

It is given in this question that a certain computer can perform number of calculations = [tex]10^{5}[/tex] per second

It has been asked that how many calculations it can perform in 10 seconds.

Since number of calculations in t seconds can be represented by

Number of calculations = Calculations done in one second × t

Where t = time

By replacing t = 10 seconds

Number of calculations = [tex]10^{5}\times 10[/tex]

                                       = [tex]10^{6}[/tex]

Computer can do the calculations = [tex]10^{6}[/tex] in 10 seconds
