Answer:
x=y/4
Step-by-step explanation:
Simply divide by 4 to get x by itself
It has orders and equally distanced value between units , the zero point characteristic makes it relevant or meaningful to say “ one object has twice the length of the other “ example
4:3 is a ratio
Answer:
![\frac{81}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B81%7D%7B8%7D)
Step-by-step explanation:
![10.125=\frac{10125^{(125}}{1000}=\frac{81}{8}](https://tex.z-dn.net/?f=10.125%3D%5Cfrac%7B10125%5E%7B%28125%7D%7D%7B1000%7D%3D%5Cfrac%7B81%7D%7B8%7D)
Answer:
Parabola with vertex at point (1,0) that goes to the right (see attached diagram).
Step-by-step explanation:
Let the complex number z be
![z=x+iy,](https://tex.z-dn.net/?f=z%3Dx%2Biy%2C)
then
![z-2=x+iy-2=(x-2)+iy\\ \\Re\ (z-2)=x-2\\ \\Im\ (z-2)=y\\ \\|z-2|=\sqrt{Re^2\ (z-2)+Im^2\ (z-2)}=\sqrt{(x-2)^2+y^2}](https://tex.z-dn.net/?f=z-2%3Dx%2Biy-2%3D%28x-2%29%2Biy%5C%5C%20%5C%5CRe%5C%20%28z-2%29%3Dx-2%5C%5C%20%5C%5CIm%5C%20%28z-2%29%3Dy%5C%5C%20%5C%5C%7Cz-2%7C%3D%5Csqrt%7BRe%5E2%5C%20%28z-2%29%2BIm%5E2%5C%20%28z-2%29%7D%3D%5Csqrt%7B%28x-2%29%5E2%2By%5E2%7D)
and
![Re\ z=x](https://tex.z-dn.net/?f=Re%5C%20z%3Dx)
Thus,
![\sqrt{(x-2)^2+y^2}=x](https://tex.z-dn.net/?f=%5Csqrt%7B%28x-2%29%5E2%2By%5E2%7D%3Dx)
Square it:
![(x-2)^2+y^2=x^2\\ \\x^2-4x+4+y^2=x^2\\ \\-4x+4+y^2=0\\ \\y^2=4x-4\\ \\y^2=4(x-1)](https://tex.z-dn.net/?f=%28x-2%29%5E2%2By%5E2%3Dx%5E2%5C%5C%20%5C%5Cx%5E2-4x%2B4%2By%5E2%3Dx%5E2%5C%5C%20%5C%5C-4x%2B4%2By%5E2%3D0%5C%5C%20%5C%5Cy%5E2%3D4x-4%5C%5C%20%5C%5Cy%5E2%3D4%28x-1%29)
This is the equation of parabola with vertex at point (1,0) that goes to the right.
