Explain the distance formula. Then use it to calculate the distance between A(1,1) and B (7,-7)

crimeas [40]

The distance formula is given by:

$d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }$

We are given two points A and B as

A(1,1) and

B(7,-7)

so we have ,

x1 = 1 , y1=1

x2= 7 and y2=-7

Plugging these in the formula we have:

$d=\sqrt{(7-1)^{2}+(-7-1)^{2} }$

d=√(36+64)

d=√100

d=10

Answer: The distance between A(1,1) and B(7,-7) is 10

What is a sequence of transformations?

MrMuchimi

Answer:

B, Two or more translations, reflections, or rotations that map a pre-image to its image

Step-by-step explanation:

A sequence is an order of events. So we want to look for an answer that includes an order of events. This already knocks out C and D.

Now we are left with A and B. It is not A because the sequence does not require all three rigid transformations.

It is B because we need at least two transformations to have an order of events and these order of events need to map the image to its pre-image. But also because the other ones were wrong. Hope this helps!
