What are the similarities in the pythagorean theorem and the distance formula

Answers

Answer:

Short answer: They are essentially the same thing.

The distance formula is derived from the Pythagorean Theorem

We have distance formula:

$D = √((x_1 - x_2)^2 + (y_1 - y_2)^2)$

Pythagorean Theorem:

$a^2+b^2=c^2 \Rightarrow c=√(a^2+b^2)$

The shortest distance between two points if a line. If you draw a line in the cartesian plane both points will have an x-coordinate and y-coordinate. Note that it forms a right triangle! Therefore, the distance between those points is the hypotenuse.

We can have a point $a=(x_(1), y_(1))$ and point $b=(x_(2), y_(2))$

But once $a$ and $b$ can be positive or negative:

$c = √(a^2+b^2)= D = √((\pm a)^2+(\pm b)^2)$

Answer:

The Pythagorean theorem states that, for all 90-degree triangles, the relationship between the lengths of the sides is given by the formula a^2 + b^2 = c^2.

DISTANCE FORMULA

The study of geometry in a graphical environment is called co-ordinate geometry.

In co-ordinate geometry, the standard formula for calculating the distance between 2 points is called the distance formula.

Step-by-step explanation:

Combine similar terms and apply the operation. Do NOT evaluate or simplify.1) 2x + 4 + 3x
2) 12 + 5x -8
3) 2x^2 + 3x^2 + 4x
4) 5ax - 12 - ax
5) 4xy + 2x + 3xy + x

Answers

1. 2x+ 4+3x
= (2x+ 3x)+ 4

2. 12 + 5x -8
= 5x + (12-8)

3. 2x^2 + 3x^2 + 4x
= (2x^2+ 3x^2)+ 4x

4. 5ax - 12 - ax
= (5ax -ax) -12

5. 4xy + 2x + 3xy + x
= (4xy+ 3xy)+ (2x+ x)

Hope this helps~

Answer:

1. 2x+ 4+3x

= (2x+ 3x)+ 4

2. 12 + 5x -8

= 5x + (12-8)

3. 2x^2 + 3x^2 + 4x

= (2x^2+ 3x^2)+ 4x

4. 5ax - 12 - ax

= (5ax -ax) -12

5. 4xy + 2x + 3xy + x

= (4xy+ 3xy)+ (2x+ x)

Show your work:Use the distributive property in two different ways to find the product of 127 and 32.

Answers

The distributive property: a(b + c) = ab + ac

127 × 32 = 127 × (30 + 2) = 127 × 30 + 127 × 2 = (130 - 3) × 30 + (130 - 3) × 2

=(130)(30) - (3)(30) + (130)(2) - (3)(2) = 3900 - 90 + 260 - 6

= 3810 + 254 = 4064

127 × 32 = (130 - 3) × 32 = 130 × 32 - 3 × 32 = 130 × (30 + 2) - 96

= (130)(30) + (130)(2) - 96 = 3900 + 260 - (100 - 4) = 4160 - 100 + 4

= 4060 + 4 = 4064

What is 9\4 as a mixed number

Answers

Okay so the formula is

1. Divide the numerator by the denominator.
2. Write down the whole number answer.
3. Then write down any remainder above the denominator.

so your answer is 2 1/4

U can divide 9 by 4 which equals 2.25 in decimal form but in fraction from it would look like this 2 1/4

RATE OF CHANGEPLZ HELP

Kim=green Trey= Red Ann=Black

JPG ATTACHED

Answers

A. you are looking for the person who reached the distance (4 miles) the fastest. Since the black line has the most distance changed in the least amount of time, Ann wins the races and has the fastest rate of change. the green line stops growing next, so Kim has the second fastest rate of change and gets second. That means that the red line ends last, has the slowest rate of change, and Trey gets third. so the race goes 1. Ann 2. Kim 3. Trey

Rate of change (speed) just means the distance traveled divided by the time it took. so we can do this for each person. Ann traveled 4 miles in 12 minutes, so you do 4/12 and get her rate of change which is 1/3 or .33 repeating
Next, we need to find Kim's rate of speed, so we take the distance she traveled (4 miles) divided by the time it took (16 minutes) if we do that we get 1/4 or .25
With Trey, he started at 2 miles, so his distance would be his final spot minus his starting spot, so he traveled 2 miles. if we take that and divide it by the time it took (18 minutes) we get 1/9 or .11 repeating.

Finally, we already found out that Ann has the fastest rate (1/3) and Trey has the slowest rate (1/9) we can prove this by stating that Ann traveled the most distance in the least amount of time. she traveled 4 miles in 12 minutes, which is greater than or equal to the other to distances by less than both times taken.

We can prove that Trey has the slowest rate because he traveled the least distance (2 miles) in the most time (18 minutes) that means that he took longer than the other two to travel less distance. his distance is less than the others and his time taken is greater than both of the other racers' times.
