Case Based Questions Test: Polynomials - Question 3

### Direction: Read the following text and answer the following questions on the basis of the same:An asana is a body posture, originally and still a general term for a sitting meditation pose, and later extended in hatha yoga and modern yoga as exercise, to any type of pose or position, adding reclining, standing, inverted, twisting, and balancing poses. In the figure, one can observe that poses can be related to representation of quadratic polynomial.The two zeroes in the above shown graph are

Detailed Solution for Case Based Questions Test: Polynomials - Question 3

Here,

Zeroes are the values of x where graph intersects the x-axis

Therefore, Zeroes are -2 and 4

Case Based Questions Test: Polynomials - Question 4

Direction: Read the following text and answer the following questions on the basis of the same:

An asana is a body posture, originally and still a general term for a sitting meditation pose, and later extended in hatha yoga and modern yoga as exercise, to any type of pose or position, adding reclining, standing, inverted, twisting, and balancing poses. In the figure, one can observe that poses can be related to representation of quadratic polynomial.

The shape of the poses shown is

Detailed Solution for Case Based Questions Test: Polynomials - Question 4

The shape of the poses shown is Parabola.

Case Based Questions Test: Polynomials - Question 5

Direction: Read the following text and answer the following questions on the basis of the same:

An asana is a body posture, originally and still a general term for a sitting meditation pose, and later extended in hatha yoga and modern yoga as exercise, to any type of pose or position, adding reclining, standing, inverted, twisting, and balancing poses. In the figure, one can observe that poses can be related to representation of quadratic polynomial.

In the graph, how many zeroes are there for the polynomial?

Detailed Solution for Case Based Questions Test: Polynomials - Question 5
Number of zeroes is equal to number of times parabola intersects the x-axis

Therefore, Number of zeroes = 2

Case Based Questions Test: Polynomials - Question 6

Direction: Read the following text and answer the following questions on the basis of the same:

Applications of Parabolas: Highway Overpasses/ Underpasses

A highway underpass is parabolic in shape.

Shape of Cross Slope:

Parabola

A parabola is the graph that results from p(x) = ax2 + bx + c.

Parabolas are symmetric about a vertical line known as the Axis of Symmetry.

The Axis of Symmetry runs through the maximum or minimum point of the parabola which is called the vertex.

The number of zeroes that polynomial f(x) = (x – 2)2 + 4 can have is:

Detailed Solution for Case Based Questions Test: Polynomials - Question 6
We have,

f(x) = (x – 2)2 + 4

= x2 + 4 – 4x + 4

= x2 – 4x + 8.

i.e., It has no factorisation.

Hence no real value of x is possible, i.e., no zero.

Case Based Questions Test: Polynomials - Question 7

Direction: Read the following text and answer the following questions on the basis of the same:

Applications of Parabolas: Highway Overpasses/ Underpasses

A highway underpass is parabolic in shape.

Shape of Cross Slope:

Parabola

A parabola is the graph that results from p(x) = ax2 + bx + c.

Parabolas are symmetric about a vertical line known as the Axis of Symmetry.

The Axis of Symmetry runs through the maximum or minimum point of the parabola which is called the vertex.

The highway overpass is represented graphically. Zeroes of a polynomial can be expressed graphically. Number of zeroes of polynomial is equal to number of points where the graph of polynomial:

Detailed Solution for Case Based Questions Test: Polynomials - Question 7
We know that the number of zeroes of polynomial is equal to number of points where the graph of polynomial intersects X-axis.
Case Based Questions Test: Polynomials - Question 8

Direction: Read the following text and answer the following questions on the basis of the same:

Applications of Parabolas: Highway Overpasses/ Underpasses

A highway underpass is parabolic in shape.

Shape of Cross Slope:

Parabola

A parabola is the graph that results from p(x) = ax2 + bx + c.

Parabolas are symmetric about a vertical line known as the Axis of Symmetry.

The Axis of Symmetry runs through the maximum or minimum point of the parabola which is called the vertex.

The representation of Highway Underpass whose one zero is 6 and sum of the zeroes is 0, is:

Detailed Solution for Case Based Questions Test: Polynomials - Question 8
x2 – 36 = 0

⇒ x2 = 36

Case Based Questions Test: Polynomials - Question 9

Direction: Read the following text and answer the following questions on the basis of the same:

Applications of Parabolas: Highway Overpasses/ Underpasses

A highway underpass is parabolic in shape.

Shape of Cross Slope:

Parabola

A parabola is the graph that results from p(x) = ax2 + bx + c.

Parabolas are symmetric about a vertical line known as the Axis of Symmetry.

The Axis of Symmetry runs through the maximum or minimum point of the parabola which is called the vertex.

If the highway overpass is represented by x2 – 2x – 8.Then its zeroes are

Detailed Solution for Case Based Questions Test: Polynomials - Question 9
x2 – 2x – 8 = 0

or, x2 – 4x + 2x – 8 = 0

or, x(x – 4) + 2(x – 4) = 0

or, (x – 4) (x + 2) = 0

or, x = 4, x = – 2

Case Based Questions Test: Polynomials - Question 10

Direction: Read the following text and answer the following questions on the basis of the same:

Applications of Parabolas: Highway Overpasses/ Underpasses

A highway underpass is parabolic in shape.

Shape of Cross Slope:

Parabola

A parabola is the graph that results from p(x) = ax2 + bx + c.

Parabolas are symmetric about a vertical line known as the Axis of Symmetry.

The Axis of Symmetry runs through the maximum or minimum point of the parabola which is called the vertex.

Graph of a quadratic polynomial is a:

Detailed Solution for Case Based Questions Test: Polynomials - Question 10
Here, the given graph of a quadratic polynomial is a parabola.
