question 3-5

Soalan / Question 3 Diberi persamaan bulatan, Given the equation of circle, 4x2 + y? - 12x + By + 16 = 0, a) Tunjukkan bahawa persamaan bulatan di dalam bentuk piawai adalah, Show that the circle equations in the standard form is, (2x - 3)2 + (y +4)? = 32 (4 markah/ marks) SULIT / CONFIDENTIAL SM0015 b) Lakarkan graf tersebut. Sketch the graph. (2 markah/ marks) c) Dari soalan (b), nyatakan persamaan tangen kepada bulatan pada titik (3-4). From question (b), state the equation of the tangent to the circle at the point (. -4). (1 markah/ marks) Soalan / Question 4 a) Rasionalkan penyebut bagi 3+41 3-27 dan nyatakan dalam bentuk a + bi. Rationalise the denominator of 3+41 3-21 and express it in the form a + bi. (4 markah/ marks) b) Cari modulus dan hujah z = 5 + 2i. Find the modulus and argument of z = 5 + 2i. (4 markah/ marks) Soalan / Question 5 Polinomial p(x) didefinisikan sebagai The polynomial p(x) is defined by p(x) = 5x3 + ax? + bx - 16, yang mana a dan b adalah pemalar. Diberi (x - 2) adalah factor bagi p(x) dan bakinya adalah 27 apabila p(x) dibahagi dengan (x + 1). where a and b are constants. It is given that (x - 2) is a factor of p(x) and that the remainder is 27 when p(x) is divided by (x + 1). 2 SULIT / CONFIDENTIAL SM0015 a) Cari nilai-nilai bagi a dan b. Find the values of a and b. (5 markah/ marks) b) Maka faktorkan p(x) selengkapnya. Hence factorise p(x) completely. (3 markah/ marks)
