Here's the solution,
The given figure is of a parallelogram,
and we know that opposite sides of a parallelogram are equal, so
=》
=》
=》
and,
=》
=》
=》
hence, the values are :
x = 24
y = 19
The inequality is,
we have given that the solution set
2, 1, 3. 9, 4 2001. 3, 4, 0, 2. 6 1. 1, 1. 5, 19. 7, 8. 2 11, 1, 48. 5, 7.
here we have given that all the values of x are positive and
Which is the smallest point in above set?
0
and
Which is the highest point in the above set?
2001.3
Therefore,
we have a=0 and b=2001.2
Our equality lie in a and b
Therefore,
Plug the value of a and b we get
Therefore we get the inequality is,

Given:
The function is:
To find:
Express the quadratic equation in the form of , then state the minimum or maximum value,axis of symmetry and minimum or maximum point.
Solution:
The vertex form of a quadratic function is:
...(i)
Where, a is a constant, (h,k) is the vertex and x=h is the axis of symmetry.
We have,
It can be written as:
Adding and subtracting square of half of coefficient of x inside the parenthesis, we get
...(ii)
On comparing (i) and (ii), we get
Here, a is negative, the given function represents a downward parabola and its vertex is the point of maxima.
Maximum value = 10.125
Axis of symmetry :
Maximum point = (1.75,10.125)
Therefore, the vertex form of the given function is , the maximum value is 10.125, the axis of symmetry is
and the maximum point is (1.75,10.125).
