Basically, you have two circles. You are asked to take circle 1 and "move it" so that it is on top of circle 2. This process of moving is called a translation and can be thought of as sliding. You do this by ensuring that the two have the same center. So, starting at (-4,5) how do you have to move to end up at (2,1)?
To do this we need to move right 6 as the x-coordinate goes from -4 to 2. We also need to move down 4 as the y-coordinate goes from 5 to 1. So we add 6 to the x-coordinate and subtract 4 from the y-coordinate. The transformation rule is (x+6, y-4).
Once you do this the circles have the same center. Next you wish to dilate circle 1 so it ends up being the same size at circle 2. That means you stretch it out in such a way that it keeps its shape. Circle 1 has a radius of 2 centimeters and circle 2 has a radius of 6 centimeters. That is 3x bigger. So we dilate by a factor of 3.
Translations and dilations (along with reflections and rotations) belong to a group known as transformations.
Answer: 20.25ft
1. Find what 8 inches in scale equal for the height of the house.
we will do this step by multiplying.
2in=4.5
8=?
to find...
2x4=8
so
4.5x4=18
2. Find what 1 inch on the scale is equal to for the height of the house.
we will do this by dividing 4.5 by 2
4.5/2=2.25
3. Add both the values for step 1 and 2.
we will do this by just adding them both
18+2.25=20.25
<h2>Why is this our answer?</h2>
This is our answer, because first we found the value of 8 inches on the scale, which means that we are finding almost the full value of the 9 inches of the height of the house, then, we found 1 inch because 9-8=1, so if we already found 8, which is a number in the table of 2, we found out 1 so that we can add it with 8 to find the value of 9in on the scale. In this way, after adding, that gives us the value of 9in on the scale!
My gratitude attitude - THANKS!
The answer would be C)3-x/x(x-1)
