Answer:
5
Step-by-step explanation:
There are 2 ways to look at this. I will explain both.
First we have the 3-4-5 triangle method, stating that any triangle with sides 3 and 4 will have the last side as 5.
Now, for the more complex way of doing this, we can use the Pythagorean theorem to solve this problem.
Pythagorean theorem: 
We can use 4 for a and 3 for b
You will now have
Then take √25, or 5.
Answer:
A dilation transformation is by shrinking or expanding the image by a scale factor x. To perform a dilation multiply the coordinates by the scale factor number given.

Answer:
9/16
Step-by-step explanation:
First, note that 10000 multiplied by .5625 will get rid of the decimal point. Therefore, make a fraction where the numerator is .5625 times 10000 and denominator is 10000 like this:
.5625 x 10000
10000
Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:
5625
/10000
The greatest common factor of 5625 and 10000 is 625, which means you can divide the numerator and denominator by 625 and keep the same value:
5625 ÷ 625
/10000 ÷ 625
And when calculating the numerator and denominator in our fraction above, we get .5625 as a fraction in the simplest form possible:
.5625 =
9
/16
