The 21 consonants are :
b c d f g h j k l m n p q r s t v w x y z
The 5 vowels are :
a e i o u
Now, to arrange the consonants there are 21! ways.
Now the vowels can be arranged in 22 ways because one vowel can be placed before 'b' and one after 'z' also.
It can be shown like this : (V represents vowels)
V b V c V d V f .......................
Therefor the ways to put vowels will be :
The complete order to place consonants without repeating vowels becomes:
Its an indirect proof, so 3 steps :-
1) you start with the opposite of wat u need to prove
2) arrive at a contradiction
3) concludeReport · 29/6/2015261
since you wanto prove 'diagonals of a parallelogram bisect each other', you start wid the opposite of above statement, like below :- step1 : Since we want to prove 'diagonals of a parallelogram bisect each other', lets start by assuming the opposite, that the diagonals of parallelogram dont bisect each other.Report · 29/6/2015261
Since, we assumed that the diagonals dont bisect each other,
OC≠OA
OD≠OBReport · 29/6/2015261
Since, OC≠OA, △OAD is not congruent to △OCBReport · 29/6/2015261
∠AOD≅∠BOC as they are vertical angles,
∠OAD≅∠OCB they are alternate interior angles
AD≅BC, by definition of parallelogram
so, by AAS, △OAD is congruent to △OCBReport · 29/6/2015261
But, thats a contradiction as we have previously established that those triangles are congruentReport · 29/6/2015261
step3 :
since we arrived at a contradiction, our assumption is wrong. so, the opposite of our assumption must be correct. so diagonals of parallelogram bisect each other.
Answer:
C
Step-by-step explanation:
There is a cross with the axis
2/10 or 1/5 gallon water is left because 8/10 - 6/10 = 2/10 = 1/5
10x^2-13x+6 (if your asking to simply the equation seeing as there is no equal sign)
