Dori claims that 3.52 is not a rational number because its not written as a ratio of integers. is she correct

Incorrect

Step-by-step explanation:

We are given that a number 3.52

Dori claims that 3.52 is not a rational number because it is not written as  a ratio of integers.

We have to find she is correct.

Rational number : It is that number which can be written in the from of where p and q are integers, .

When we remove decimal then we write 100 in denominator because two digits after decimal point.

If the denominator of given number can be written as

Then the number is terminating rational number.

Hence, the given number is rational number.

Therefore, Dori is wrong.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
