A and B are on the line 3x+2y=6. At A x=0, what is y? At B y=0, what is x?

To find the y value at A, we know that x is equal to zero. This can be put into the equation of the line so that 3(0)+2y=6. Therefore 2y=6, and to get the y value, we divide each side by 2, giving us y=3 at ...

Find the turning value of the following function, stating whether the value is min or max, y = x^2 -6x + 5

First the student needs to differentiate the function to find dy/dx = 2x-6At dy/dx = 0, we know the curve is stationary. Now we can work out the x value such that x = 3Put x=3 back into the original equation...

The sixth term of an arithmetic sequence is 8 and the sum of the first 15 terms is 60. Find the common difference and list the first three terms.

Formulae to be used: n th term of an arithmetic sequence u n = u 1 + (n-1)d and sum of the first n terms of an arithmetic series S n = (n/2) * (2u 1 + (n-1)d) Substitute known values: u 1 + 5d = 8(15/2) * (2...
