Find the distance between A and B. Round to the nearest hundredth. <br> ​A (-7,-1)<br> ​B (6,-5)
taurus [48]

Answer:

The distance between A and B is 13.6

Step-by-step explanation:

Distance formula=√(x2-x1)²+(y2-y1)²

Where

x1=-7

x2=6

y1=-1

y2=-5

Putting in the formula

Distance=√(6+7)²+(-5+1)²

D=√(13)²+(-4)²

D=√169+16

D=√185

D=13.6

2. State the negation of each of the following statements. a. √ is a rational number. b. 0 is not a negative integer. c. 111 is
maxonik [38]

The negation of the statements are:

  • a. √ is not a rational number.
  • b. 0 is a negative integer.
  • c. 111 is not a prime number.

<h3>How to determine the negation?</h3>

The negation of a statement x is represented as:

not x

This means that we simply introduce the "not" word in the statements or we remove the "not" word in them

So, we have the negation to be:

  • a. √ is not a rational number.
  • b. 0 is a negative integer.
  • c. 111 is not a prime number.
