(Given) Perimeter of the given shape will be equal to = Circumference of half semi circle (APB) + Circumference of quarter semicircle AQO + QO RADIUS + OB RADIUS = ( PI * R ) + (0.5 * PI * R) + R + R But this perimeter is given equal to the 47 cm.Hence, ( ...
CHAPTER O2 PART B POLYNOMIALSIn the Figure given below, find the number of zeroes in each case. How to Calculate Zeroes, when the Graph of a Polynomial has been given ? The Zeroes of a Polynomial indicates the values of 'x' at which the value of polynomial p(x) becomes zero. Hence In a Grapgh plotted for the Polynomial, the points at which the value of Polynomials ...
Chapter 02 Polynomials Problem No 01 :- Find the Zeros of the Polynomials and verify the relationship between the zeros and coefficients :-x2 + 7x + 12To find the zeros of polynomial, It should be equated to zero firstHence,x2 + 7x + 12 = 0Or, x2 + 4x + 3x + 12 = 0Or, x (x + 4)+ 3 (x + 4 ) = 0Or, (x + 3) * (x + 4 ) = 0It implies that x = - 3 & -4 Ans ...............................................
