Hi Ndawana, From the information provided about the remainders when f(x) is divided by each of x-3 and 2x-1, we know that f(3) = -9 and f(1/2) = -6. Since the product (x-3)(2x-1) is quadratic then the

Hi AB, The modulus of a complex number z = a + bi is given by the positive value of |z| = √(a² + b²) So, for x = 2 + 3i |x| = √(2² + 3²) = √13 which is not the same as 13, and

Hello Apsara, The first thing you need to know about percentages is that they are just a way of comparing two quantities to each other. So, 60% of 180 is just a number such that if you compare the size

Hi Kenneth, Yes, the inverse relationship means that you can't divide in that sense. In this case, the number of pipes multiplied by the time it takes to drain the tank is a constant, assuming pipes of

Hi Kenneth, In cases like this it would be unlikely that all the quantities would be directly proportional, but it would be correct to perform appropriately similar operations on those that are directly
