Answer:
(5x^12)/(-2y^8)
-((5x^12)/(2y^8))
Step-by-step explication:
Move the negative sign by multiplying both the numerator and denominator by -1
(5x^12)/(-2y^8)
Move the negative sigh out of the fraction by factoring out -1
-((5x^12)/(2y^8))
Answer:
C
Step-by-step explanation:
I can't understand what you'r saying because of the " A. B. C words" but the answer will be C 120(0.053) but since I can't understand the question i think it's this answer but next time can you make you'r question more easy to read.
Hope you understand....
Answer:
0.25
Step-by-step explanation:
The fraction is 18/72. The decimal is different. If you divide 72 by 18, you get 4. That tells you how it is in a quarter, aka four pieces. Divide 100 by 4, you get 25. That’s why the answer is 0.25
Unit vector along the direction v = <3,1,-4> is :
![\hat{v} = \dfrac{3i + j -4k}{\sqrt{3^2 + 1^2 + 4^2}}\\\\\hat{v} = \dfrac{3i + j -4k}{5.1}](https://tex.z-dn.net/?f=%5Chat%7Bv%7D%20%3D%20%5Cdfrac%7B3i%20%2B%20j%20%20-4k%7D%7B%5Csqrt%7B3%5E2%20%2B%201%5E2%20%2B%204%5E2%7D%7D%5C%5C%5C%5C%5Chat%7Bv%7D%20%3D%20%5Cdfrac%7B3i%20%2B%20j%20-4k%7D%7B5.1%7D)
So, unit vector opposing the
is :
![\hat{v'} = -\hat{v}\\\\\hat{v'} = -( \dfrac{3i + j -4k}{5.1})\\\\\hat{v'} = \dfrac{-3i - j +4k}{5.1}](https://tex.z-dn.net/?f=%5Chat%7Bv%27%7D%20%3D%20-%5Chat%7Bv%7D%5C%5C%5C%5C%5Chat%7Bv%27%7D%20%3D%20-%28%20%5Cdfrac%7B3i%20%2B%20j%20-4k%7D%7B5.1%7D%29%5C%5C%5C%5C%5Chat%7Bv%27%7D%20%3D%20%5Cdfrac%7B-3i%20-%20j%20%2B4k%7D%7B5.1%7D)
so, vector of magnitude 3 units in opposite direction from v is :
![\vec{V} = 3\hat{v'}\\\\\vec{V} = \dfrac{3}{5.1}( -3i -j+4k)](https://tex.z-dn.net/?f=%5Cvec%7BV%7D%20%3D%203%5Chat%7Bv%27%7D%5C%5C%5C%5C%5Cvec%7BV%7D%20%3D%20%5Cdfrac%7B3%7D%7B5.1%7D%28%20-3i%20-j%2B4k%29)
Hence, this is the required solution.
