You have a total of £385 to split to Charlie, Ben and Sarah in the ratio of 1:2:4. First, I ask myself how many parts am I splitting the £385 into?From the ratio, I know the total number of parts = 1 + 2 ...
The first step in solving this problem is to identify that it is an integral that needs to be solved by parts. When you see an integral, check if it is in the form uv, where u and v are both functions...
Frictional force acting:FMax= uR = 0.7 x 5 x 9.81 x cos(30) FMax = 29.7NWeight acting down the slope:F = 5 x 9.81 x sin(30)F = 24.5NFric...
This question is split up into two parts.Firstly recall the trigonometric identities you know, the trick here is to eliminate one of the squared terms. Using 4sin^2(x) +4cos^2(x) = 4, the cos term i...
First cancel down the fractions to make the numbers as small as possible, then make all fractions have the same denominator. 12/30 becomes 2/5. 14/20 becomes 7/10. So the new fractions are 4/5 3/8 2/5 and...
