Points A and B have coordinates (–2, 1) and (3, 4) respectively. Find the equation of the perpendicular bisector of AB and show that it may be written as 5x +3 y = 10.

Formula for a straight line y-y 1 =m(x-x 1 ), where m is the gradient substituting in the values given to find the gradient we get 4-1=m(3+2), therefore m= 3/5the midpoint of the two points is ((x 1 + x 2 )/...

Find the values of x for which f(x) is an increasing function given that f(x)=8x-2x^2

When a function is increasing, it’s derivative is positive. So first let us differentiate f(x). To differentiate x n we multiply by n and then reduce the power by 1. So f’(x)=8-2*2x=8-4x. We want to find the...
