4 0.10 that is answer of this question
Answer:
2 CH4(g) + 4 O2(g) --> 2 CO2 (g)+ 4 H2O(g)
Step-by-step explanation:
The number are subscripts.
Now count the number of each kind of atom on the left and right side of the equation. Note, you have 4 H on the left and as written you have only 2 on the right. So add a coefficient-- a number in front of the formula.
CH4 +O2 ----- CO2 + 2 H2O
With the added coefficient in front of water, the number of hydrogens balance but the number of oxygens do not. There are only 2 oxygens on the left and a total of 4 oxygens on the right. A coefficient of 2 in front of oxygen on the left balances the equation.
Answer:
Step-by-step explanation:
The exponential decay function is
where a is the initial value of the car, b is the rate of decay, and t is the time in years. Our rate of decay can also be written as (1 - r) where r is the depreciation in decimal form. Our equation looks like this:
which simplifies to
Now we can solve our problem for any number of years you'd like. We've been tasked to find the value of the car after 3 years, so:
which simplifies a bit to:
so
v(t) = 8043.57
None of the above because j+j+2k will give you 2j+2k and 2(j+j+k) will come out as 2j+2j+2k Hope this helps!
Given:
The functions are:
The function f(x) is dilated to become g(x).
To find:
The effect on f(x).
Solution:
Transformation is defined as:
...(i)
Where, k is the factor of horizontal stretch and compression.
If 0<k<1, then the graph of f(x) stretched horizontally by factor 
.
If k>1, then the graph of f(x) compressed horizontally by factor .
It is given that
...(ii)
On comparing (i) and (ii), we get
Therefore, the graph of f(x) stretched horizontally by factor 
.
