The distance be<br> Find the distance between P and Q
Lelu [443]

9514 1404 393

Answer:

  10

Step-by-step explanation:

The distance formula is useful.

  d = √((x2 -x1)^2 +(y2 -y1)^2)

  d = √((7 -1)^2 +(12 -4)^2) = √(6^2 +8^2) = √(36 +64) = √100

  d = 10

The distance between P and Q is 10.

<em>Additional comment</em>

You may recognize the run : rise ratio of 6 : 8 = 3 : 4. This suggests a 3-4-5 right triangle with a scale factor of 2. If you're familiar with that Pythagorean triple, you can write down the answer as soon as you see the rise and run numbers.

What is the answer I've been trying for three hrs my teacher said to look it up so plz help
marin [14]
There are four s's and two sevens. Two times seven is fourteen and four times s is 4s. So then you have 4s + 14. Subtract 14 from 114 and then divide the quotient by 4. This should get you 25. so then every side is 25, and for the length it's 32 because s=25 and the equation you have says s+7. The dimensions would be 25 plus 25 plus 32 plus 32

WILL MARK BRAINLIEST HELP PLEASE
denis-greek [22]

Answer:

7.) m = 1/3 ; b = -2.5

8.) m = 2 ; b = 2

Step-by-step explanation:

For m, either do the rise over run method or use 2 points and do (y2-y1)/(x2-x1).

For b, just look at the y-intercept/where it crosses the y axis

I believe those are the right answers but not too sure because the numbers on the graph are a bit blurry so i just assumed it counted by ones.

Answer:

The correct answer is: {2,4,6,8}

Step-by-step explanation:

Given sets are:

P = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and V= {2, 4, 6, 8, 10, 12, 14, 16, 18, 20)

We have to find

P∩V

The symbol is used for intersection of two sets. In intersection, only common elements of both sets are written in result.

So,

P∩V = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9) ∩ {2, 4, 6, 8, 10, 12, 14, 16, 18, 20)

P∩V = {2,4,6,8}

Hence,

The correct answer is: {2,4,6,8}
