If the rice increases in weight from 60g to 145g, the factor by which it increases is: (145/60) = 2.4166...
There are a few ways to tackle this particular style of problem. First off we can try doing it without using any bracket theory and just focus on the raw numbers (a somewhat simpler approach). Step 1: We'...
(3x + 1)2 = 9x2 + 6x + 1 (3x - 1)2 = 9x2 - 6x + 1 (9x2 + 6x + 1) - (9x2 - 6x + 1) = 12x 12x/4 = 3x Therefore for all positive integers of ...
u = Cos(x3)
To differentiate this function we will use the chain rule. Firstly we will set x3 to another variable name such as v. So now v = x3 . Lets differentia...
To do this we will assume sqrt(2) is rational, a fraction, which means: 21/2 = m/n; m,n belong to integers. Also, m/n is an irreductible fractionJCAnswered by Joao C. • Maths tutor3225 Views
