The distance between (-4,3,-6) and the origin is ![\sqrt{61](https://tex.z-dn.net/?f=%5Csqrt%7B61)
<h3>How to determine the distance?</h3>
The point is given as:
(x, y, z) = (-4,3,-6)
The origin is
(x, y, z) = (0,0,0)
The distance between the point and the origin is calculated as:
![d = \sqrt{x^2 + y^2 + z^2](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7Bx%5E2%20%2B%20y%5E2%20%2B%20z%5E2)
So, we have:
![d = \sqrt{(-4)^2 + (3)^2 + (-6)^2](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28-4%29%5E2%20%2B%20%283%29%5E2%20%2B%20%28-6%29%5E2)
Evaluate
![d = \sqrt{61](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B61)
Hence, the distance between (-4,3,-6) and the origin is ![\sqrt{61](https://tex.z-dn.net/?f=%5Csqrt%7B61)

Answer:
40%
Step-by-step explanation:
Let x = numerator
Let y = denominator
![\implies \dfrac{x}{y}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7Bx%7D%7By%7D)
Decreased by 30% = 100% - 30% = 70% = 70/100 = 0.7
Decreased by 50% = 100% - 50% = 50% = 50/100 = 0.5
![\implies \dfrac{0.7x}{0.5y}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7B0.7x%7D%7B0.5y%7D)
![\implies \dfrac{0.7}{0.5}=1.4](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7B0.7%7D%7B0.5%7D%3D1.4)
![\implies 1.4 \ \dfrac{x}{y}](https://tex.z-dn.net/?f=%5Cimplies%201.4%20%5C%20%5Cdfrac%7Bx%7D%7By%7D)
1.4 as a percentage = 1.4 x 100 = 140%
Therefore, the percentage increase is 140 - 100 = 40%
