For the diagram below which equation is the correct use of the distance formulathe last one d is d= √(11-6)^2 + (5-y2)^2

The correct equation is,

Step-by-step explanation:

If and are the endpoints of a line segment,

Then by the distance formula,

The length of the line segment is,

Here, (5,6) and (11, ) are the endpoint of the line segment which has the length 6.71,

Thus, d = 6.71, ,

Which is the required equation.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
