Answer:
(x-5)(x+5)
Step-by-step explanation:
Someone else asked the same question and got something written out for them. on another site, I found out that the first one was <span>: 8(14.13)=113.04</span>
Set it up kind of like a picket fence. Put 149 g over one cm and multiply that by 1kg over 1000g then multiply that by 1 cm over .01 m. The answer is 14.9 kg/m
Negative correlation refers to an inverse relationship between two variables. When one variable increases, the other decreases.
The variables are latitude and average temperature.
The explanatory variable is latitude and the response is the average temperature. Choice B.
As the latitude increases, the average temperature decreases. This is a strong negative correlation of between the two variables.
For this case we must simplify the following expression:
![\frac {6-3 \sqrt [3] {6}} {\sqrt [3] {9}}](https://tex.z-dn.net/?f=%5Cfrac%20%7B6-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%7D%20%7B%5Csqrt%20%5B3%5D%20%7B9%7D%7D)
Multiplying the numerator and denominator by![(\sqrt [3] {9}) ^ 2](https://tex.z-dn.net/?f=%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%202)
![\frac {6-3 \sqrt [3] {6}} {\sqrt [3] {9}} * \frac {(\sqrt [3] {9}) ^ 2} {(\sqrt [3] { 9}) ^ 2} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B6-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%7D%20%7B%5Csqrt%20%5B3%5D%20%7B9%7D%7D%20%2A%20%5Cfrac%20%7B%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%202%7D%20%7B%28%5Csqrt%20%5B3%5D%20%7B%209%7D%29%20%5E%202%7D%20%3D)
We rewrite:
![\frac {\frac {6-3 \sqrt [3] {6}} * (\sqrt [3] {9}) ^ 2} {\sqrt [3] {9} * (\sqrt [3] {9 }) ^ 2} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B%5Cfrac%20%7B6-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%7D%20%2A%20%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%202%7D%20%7B%5Csqrt%20%5B3%5D%20%7B9%7D%20%2A%20%28%5Csqrt%20%5B3%5D%20%7B9%20%7D%29%20%5E%202%7D%20%3D)
By properties of powers we have that:
![a ^ m * a ^ n = a ^ {m + n}\\\frac {(6-3 \sqrt [3] {6}) * (\sqrt [3] {9}) ^ 2} {(\sqrt [3] {9}) ^ 3} =\\\frac {(6-3 \sqrt [3] {6}) * (\sqrt [3] {9}) ^ 2} {9} =](https://tex.z-dn.net/?f=a%20%5E%20m%20%2A%20a%20%5E%20n%20%3D%20a%20%5E%20%7Bm%20%2B%20n%7D%5C%5C%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%20%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%202%7D%20%7B%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%203%7D%20%3D%5C%5C%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%20%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%202%7D%20%7B9%7D%20%3D)
We rewrite, moving the exponent within the radical:
![\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {9 ^ 2}} {9} =\\\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {81}} {9} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%20%5Csqrt%20%5B3%5D%20%7B9%20%5E%202%7D%7D%20%7B9%7D%20%3D%5C%5C%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%20%5Csqrt%20%5B3%5D%20%7B81%7D%7D%20%7B9%7D%20%3D)
We can rewrite
![\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {3 * 3 ^ 3}} {9} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%20%5Csqrt%20%5B3%5D%20%7B3%20%2A%203%20%5E%203%7D%7D%20%7B9%7D%20%3D)
We simplify:
![\frac {(6-3 \sqrt [3] {6}) * 3 \sqrt [3] {3}} {9} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%203%20%5Csqrt%20%5B3%5D%20%7B3%7D%7D%20%7B9%7D%20%3D)
We apply distributive property:
![\frac {18 \sqrt [3] {3} -9 \sqrt [3] {18}} {9} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B18%20%5Csqrt%20%5B3%5D%20%7B3%7D%20-9%20%5Csqrt%20%5B3%5D%20%7B18%7D%7D%20%7B9%7D%20%3D)
Simplifying we finally have:
![2 \sqrt [3] {3} - \sqrt [3] {18}](https://tex.z-dn.net/?f=2%20%5Csqrt%20%5B3%5D%20%7B3%7D%20-%20%5Csqrt%20%5B3%5D%20%7B18%7D)
