QUESTION: 1

### The area (in square units) of the region enclosed by the curves y = x2 and y = x3 is

Solution: By solving equations 1and 2 we can get 0,1as values for x which can be the limits and by subtracting y=x^2 from x^3 and integrating the result within the limits 0 to 1 we can get area = 1\12

Solution:
QUESTION: 6

The order and degree of differential equation √(dy/dx) - 4 (dy/ dx) - 7x = 0 are

Solution:

√(dy/ dx)- 4 (dy/dx) -7x = 0
or √(dy/ dx) = 4 (dy/dx) + 7x
Squaring both side
dy/ dx = [4 (dy/dx ) + 7x]2
or dy dx = 16 ( dy/dx )2 + 49x2 + 56 dy/ dx x
∴ order = 1
degree = 2

QUESTION: 25

The latus rectum of the parabola y2 = 5x + 4y + 1 is

Solution:

y2 = 5x + 4y + 1
or y2 - 4y = 5x + 1
or y2 - 2.2.y + (2)2 - (2)2 = 5x + 1
or (y - 2)2 = 5x + 5
or (y - 2)2 = 5(x + 1)
Length of the latus rectum = 5

QUESTION: 26

Solution:
QUESTION: 27

A polygon has 44 diagonals. The number of its sides is

Solution: The number of diagonals for n sided polygon = [n(n-3)]/2Â . therefore, => 44 = [n(n-3)]/2Â . => n^2 - 3n - 88 = 0Â . => (n+8)(n-11) =0. => n = -8 or 11. Neglect n = -8. Therefore, => n = 11Â . therefore, the no. of sides = 11 Hence, correct answer is (B).
