What is the distance, to the nearest hundredth, from (6, 5) to (−3, −8)?
Olin [163]

Answer:

15.81

Step-by-step explanation:

Use the distance formula:

So the distance formula for two given points is

Distance= sqrt((x2-x1)^2 +(y2-y1)^2 ) =sqrt((-3-6)^2 +(-8-5)^2 )

=sqrt((-9)^2 +(-13)^2 )

=sqrt(81+169)

=sqrt(250)

=15.81

Hope this helped

Solve for x. Leave your answer in simplest radical form
alexandr1967 [171]

Answer:

x = 2√7

using Pythagoras theorem:

  • 7² + ?² = 9²
  • ?² = 81 - 49
  • ? = √32
  • ? = 4√2

For the bottom part:

  • x² + 2² = (4√2)²
  • x² + 4 = 32
  • x² = 28
  • x = √28
  • x = 2√7

I don’t know how to do this. HELP!
Karo-lina-s [1.5K]

Answer:

1/4

Step-by-step explanation:

coins have 2 sides, tails and heads, so for it to land on tails is a 1/2 chance. Dice have 6 sides and 1,3,5 are all odd so its a 3/6 chance. Simplify 3/6 to 1/2 and multiply by 1/2 to get 1/4. im not sure, its my guess.
