a.
To find: The area of land in terms of length
The area of page in terms of width
Given:
The print area is
Formula used:
The area of rectangle is
Calculation:
Let the width of print area be
The area is length multiplied by breadth.
The total length of the page is top border plus bottom border plus the length of print area.
The total width of the page is left border plus right border plus the width of print area.
The area of the page is
Conclusion:
The area of the page is
b.
To find: Check whether it has horizontal asymptote find the asymptote if it has and give the reason if there is no horizontal asymptote.
Yes, there is a horizontal asymptote at
Given:
The model is
Concept used:
To find the horizontal asymptote find the degree of the numerator and denominator.
Three cases can arise.
- When the degree of numerator is less than the degree of the denominator.
- When the degree of numerator is equal to the degree of the denominator.
- When the degree of numerator is greater than the degree of the denominator.
Then the horizontal asymptote will be
Then the horizontal asymptote will be
Then there will be no horizontal asymptote.
Calculation:
The model is
The degree of numerator is equal to the degree of the denominator.
The horizontal asymptote is as shown below.
Conclusion:
Yes, there is a horizontal asymptote at

In an elementary chemical reaction, single molecules of two reactants A and B form a molecule of the product C : ABC. The law of mass action states that the rate of reaction is proportional to the product of the concentrations of A and B: d[C] dt = k[A][B] (where k is a constant positive number). Thus, if the initial concentrations are [A] = = a moles/L and [B] = b moles/L we write x = [C], then we have (E): dx dt = k(ax)(b-x) 1 (a) Write the differential equation (E) with separate variables, i.e. of the form f(x)dx = g(t)dt.
