I can get it into standard form of that certain conic section by completing the square
<span>
</span>
(x^2-2x)+(y^2-4y)-31=0
<span>
</span>
(x^2-2x+1-1)+(y^2-4y+4-4)-31=0
<span>
</span>
(x-1)^2-1+(y-2)^2-4-31=0
<span>
</span>
(x-1)^2+(y-2)^2-36=0
<span>
</span>
(x-1)^2+(y-2)^2=36
<span>
</span>
(x-1)^2+(y-2)^2=6^2
in form
(x-h)^2+(y-k)^2=r^2
r=radius
so how wide it is is the diameter which is 2 times of radius
6=radius
6 times 2=12
12 inches I assume if the units in equation is in inches
Yo is this supposed to be in spanish
The correct answer is B. Drawing B, C, L, M, N, R, T, or Z
Further Explanation:
Let us first define complement first.
The complement of an event is the opposite of it. For example in this case, the complement of drawing a vowel will be not drawing a vowel.
So,
Let S be the set of alphabets present on scrabble tiles
Drawing a vowel will constitute
So, the complement (not Drawing a vowel) will be:
So drawing any of the consonant from the consonants present on scrabble tiles will be the complement of drawing a vowel.
Hence, Option B is correct ..
