Length of line segment
Find the length of the line segment whose endpoints are: (-3, 11) and (-4, 20)

sqrt(82)

Step-by-step explanation:

sqrt[(20-11)² + (-4--3)²]

sqrt(81+1)

sqrt(82) or 9.055 units

sqrt: square root

9.055

Step-by-step explanation:

Let A(xa,ya) and B(xb,yb) two endpoints. The length of the AB segment is:

d²=(xb-xa)²+(yb-ya)².

Now:

d²=(-4-(-3))²+(20-11)²=(-4+3)²+9²=(-1)²+81=82

d=sqrt(82)=9.055

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
