Answer 1

Answer:

Step-by-step explanation:

DeterminePS A. 2Ö3cm B. 4Ö6cm C. 2Ö6cm D. 8Ö6cm E. 8cm 8. Given that cos z = L, where z is an acute angle find an expression for Co +Z - cosecz sec Z + tan z A. l - L B. L2-Ö1-L2 C. -L-Ö1-L 1+L L2+L-1 (C1+L) +Ö1-L2 D. ÖL-1. E. L-(L2-1) (L1+L2) +Ö1-L2 1+ Ö1 - L2+ Ö1 - L2 9. If 0.0000152 x 0.00042 =Ax108,where 1 £A< 10, findAand B. A. A= 9, B= 6`.38 B. A= 6.38, B = -9 C. A= 6.38, B = 9 D. A= 6.38, B = -1 E. A= 6.38, B= 1 10. If x + 2 and x – 1 are factors of the expressions lx + 2kx2 + 24, find the values of l and k A. l=-6,k=-9 B. l=-2,k= 1 C. l=-2,k=-1 D. l=0,k= 1 E. l=6,k= 0 11. Make T the subject of the equation av = 3 2V + T 1- V a 2T A. 3av/(1-v) B. 2v(1-v)2 - a2v2/2a2v2 - (1-V)2 C. 2v(1 - v)2 + a3v2/ 2a2v2 + (1 - v)2 D. 2v(1 - v)2 - a4v3/2a3v3 - (1 - v)3 E. 2v(1-v)3 - a4v3/2a3v3 + (1-v)3 12. In a class of 60 pupils, the statistica
