Answer:
The balanced chemical reaction is
Step-by-step explanation:
According to Law of conservation of mass, in an chemical reaction the mass of the reactant must be equal to the mass of the product obtained in the reaction.
On the reactant side On the product side
Si = 1 Si = 1
Cl = 4 Cl = 1
H= 2 H= 2
O= 1 O= 2
Lets first balance Chlorine (Cl) by adding 4 on the product side
On the reactant side On the product side
Si = 1 Si = 1
Cl = 4 Cl = 4
H= 2 H= 4
O= 1 O= 2
Now lets balance H and O by adding 2 on the product side
On the reactant side On the product side
Si = 1 Si = 1
Cl = 4 Cl = 4
H= 4 H= 4
O= 2 O= 2
Answer:
The 9th term for given sequence is 16.777
Therefore the 9th term is .
Step-by-step explanation:
Given first three terms of a sequence are 100,80,64,...
Given , , ,...
Given sequence is of the form of Geometric sequence
Therefore it can be written as
therefore a=100 , ar=80 , ,...
To find common ratio
Therefore
The nth term of the geometric sequence is
To find the 9th tem for the given geometric sequence is
put n=9, a=100 and
Therefore
The 9th term is 16.777
g(x)= 3k-2x²
g(-3)=-6 ____(1)
So, using (1),
-6 = g(-3)
=> -6 = 3k - 2(-3)²
=> -6 = 3k - 2(9)
=> -6 = 3k - 18
=> -6 +18 = 3k
=> 12 = 3k
=> 12/3 = k
=> 4 = k
Now, you can find g(n) for any number n, as now we know the value of k. Specify the value of x, if you want to know what is g(x).
2x+11+6x-7=180
8x+4=180
8x=176
x=22
MHT= 6x-7
125
AHM= 2x+11
55
Answer:
missing value is 5
Step-by-step explanation:
Change them to all have the same denominator
8/12 + 3x/12 = 23/12
multiply all by 12
8 + 3x = 23
subtract 8
3x = 15
divide by 3
x = 5
