Question

POLYNOMIAL:

1) Find the zero of the polynomial p(X) = 3x + 4 .

CIRCLES:

1) The radius of the circle is 5cm and distance of the chord from the centre of the circle is 4cm . Find the length of the chord.

Answer 1

Answer:

x is -4/3

Length of chord is 6 cm

Step-by-step explanation:

3x + 4 = 0

3x = -4

x = -4/3

circles:

Chord Length = 2 × √(r² − d²)

here: r = 5 cm and d = 4cm

Chord length = 2 x √5² - 4²

                  = 2 x √25 - 16

                  = 2 x √9

                  = 2 x 3

                  = 6 cm
