Different, or set apart from the "regulars", special.
I hope this helps and good luck. Because I dont know what your choices are, I would just pick the closest choice to the answers me and @Mathguru17. :)
Any vector in the xy-plane has the form v = c1i + c2j + 0k
For v to be perpendicular to a, we need v · a = 0
So, 3c1 - 5c2 = 0
For example, choose c1 = 5 and c2 = 3.
Then v = 5i + 3j + 0k is perpendicular to a.
ll v ll = √[52 + 32 + 02] = √34
A unit vector in the xy-plane that is perpendicular to 3i - 5j + k is:
u = v / llvll = (5/√34)i + (3/√34)j + 0k
Answer:
Last night, my mother gave my huge dog Simon a bone after he behaved very well with our guests. However, he did not feel like eating it at that moment, so he found a place in the garden, dug the earth and buried it in the darkness. The next day, Simon wanted to eat his bone for breakfast, but he did not remember where exactly he had buriedit! Besides, the earth of the garden was being moved too to grow vegetables, so he ended up digging and making holes in the whole garden for hours. Finally, the bone was waiting for him next to a lemon tree.
