Hi Katharine, You havent done anything wrong (except maybe making a mistake in the presentation of the expression). Except that i'm missing something here, but i dont think the equation x^5 - 9x^4
Hi Stephen, 1) Let the number of 50p coins be x and those of 20p coins be y 50p in x places + 20p in y places = £17.10 i.e x(0.50) + y(0.20) = 17.10 The total number of coins is 54 and so x + y =
Hi Edward, In quadrant II, sin u and sin v are positive but all of cos u, cos v, tan u and tan v are negative. Also, sin(A+B) = sinA.cosB + sinB.cosA sin(A-B) = sinA.cosB - sinB.cosA cos(A+B) = cosA
Hi Dimitrz, 1) Yes, your calculation is correct. 2) Well, there is definitely a flaw in the assumption that your team has been utilized more. Lets work backwards here. If a person works 192 hours a
Hi Alexandra, I'm taking the 6 to be the base of logarithm here. logA + logB = logAB So, log6 (x+2) + log6 (x-1) = 3 log6 [(x+2)(x-1)] = 3 Therefore, (x+2)(x-1) = 6³ x² + x - 2 = 216 x² + x -
