Yes, the equation “N2 + 3H2 = 2NH3” is balanced.
Answer:

Step-by-step explanation:
The sum of N consecutive natural numbers is given by:

We need to find the sum of the natural numbers between 12 to 38.
To calculate the required sum we have F=12, L=38, but we don't have the value of N.
From 12 to 38 there are 38 - 12 + 1 = 27 natural consecutive numbers, thus N=27.
Substituting in the formula:




$10,000 X 0.05 = $500/year
500 X 4 years = $2,000 after 4 years
Answer with Step-by-step explanation:
Since we have given that
q = 896-20p
p = $32
.(A) Calculate the price elasticity of demand
As we know that

(B) The demand is going down with increase in 15 increase in price at that price level, as we know that there is inverse relationship between price and quantity demanded.
(C) Also, calculate the price that gives a maximum weekly revenue.

We first find the first derivative:

So, it becomes,

R=-40<0, so, it will give maximum revenue.
(D) Find this maximum revenue.
Maximum revenue would be 
Answer:
x=-3
Step-by-step explanation:
(-3+5) (-3-5)=0
(0) (-8)=0
0=0
