Understanding the Sign of the X-Coordinate in the Third Quadrant A point (x, y) lies in a specific quadrant based on the signs of its coordinates: Quadrant I → (x > 0, y > 0) Quadrant II → (x 0) Quadrant III → (x < 0, y 0, y < 0) For a Point in the Third Quadrant (III): The x-coordinateRead more

    Understanding the Sign of the X-Coordinate in the Third Quadrant
    A point (x, y) lies in a specific quadrant based on the signs of its coordinates:
    Quadrant I → (x > 0, y > 0)
    Quadrant II → (x 0)
    Quadrant III → (x < 0, y 0, y < 0)
    For a Point in the Third Quadrant (III):
    The x-coordinate is negative (x < 0).
    The y-coordinate is also negative (y < 0).
    Final Answer: (b) –

    Determining the Quadrant of Given Points
     A point (x, y) lies in a specific quadrant based on the signs of its coordinates:
    Quadrant I → (x > 0, y > 0)
    Quadrant II → (x 0)
    Quadrant III → (x < 0, y 0, y < 0)
    Analyzing Each Point
    1. Point (1 , -2)
    x = 1 (positive), y = -2 (negative). Lies in Quadrant IV
    2. Point (2, -3)
    x = 2 (positive), y = -3 (negative). Lies in Quadrant IV
    3. Point (4, -6)
    x = 4 (positive), y = -6(negative). Lies in Quadrant IV
    4. Point (2, -7)
    x = 2 (positive), y = -7 (negative). Lies in Quadrant IV
    Conclusion: All four points lie in Quadrant IV.
    Final Answer: (c) IV quadrant.

  3. The number of zeroes ( or roots) of a polynomial is determined by its degree. The degree of a polynomial is the highest exponent of the variable. Given Polynomial: x³ + x - 3 - 3x² Step 1: Arrange in Standard Form Rearrange the terms in descending order of powers of x: x³ - 3x² + x - 3 Step 2: IdentRead more

    The number of zeroes ( or roots) of a polynomial is determined by its degree. The degree of a polynomial is the highest exponent of the variable.
    Given Polynomial: x³ + x – 3 – 3x²
    Step 1: Arrange in Standard Form
    Rearrange the terms in descending order of powers of x:
    x³ – 3x² + x – 3
    Step 2: Identify the Degree
    The highest power of x is 3.
    A polynomial of degree n can have at most n zeroes.
    Conclusion: Since the given polynomial is of degree 3, it has three zeroes ( real or complex). Thus the correct answer is (d) 3.

    Correct option (a) 2x
    A polynomial consists of terms where the variable has only non-negative integer exponents.
    Analyzing Each Option:
    (a). 2x – The exponent of x is 1, which is a non-negative integer. This is a valid term of a polynomial.
    (b). 3/x – This can be rewritten as 3x ⁻¹. Since the exponent is negative, this is not a polynomial term.
    (c). x√x – We rewrite √x as x¹/², so:
    x√x = x.x¹/² = x ³/² Since the exponent 3/2 is not an integer, this is not a polynomial terms.
    (d). √x – since √x = x ¹/², and the exponent 1/2 is not a integer, this is not a polynomial term.
    Final Answer: The correct answer is (a) 2x.

  5. We need to find the value of: 104 x 96 Step 1: Use the Difference of Squares Formula We rewrite the numbers as: 104 x 96 = (100 + 4) (100 - 4) Using the identify: (a + b) (a - b) = a² - b² where a = 100 and b = 4: 104 × 96 = 100² - 4² Step 2: Compute the Values 100² = 10000 4² = 16 10000 - 16 = 9984Read more

    We need to find the value of: 104 x 96
    Step 1: Use the Difference of Squares Formula
    We rewrite the numbers as: 104 x 96 = (100 + 4) (100 – 4)
    Using the identify: (a + b) (a – b) = a² – b²
    where a = 100 and b = 4:
    104 × 96 = 100² – 4²
    Step 2: Compute the Values
    100² = 10000
    4² = 16
    10000 – 16 = 9984
    Final Answer: The correct option is: (a) 9984.
