The length 'x' of a rectangle is decreasing at the rate of 3cm/m and the width 'y' is increasing at the rate of 2cm/m.find the rates of change of : (a) the perimeter (b) the area of the rectangle when X = 8 cm and y = 6 cm.
find the equation of the circle which passes through the centre of the circle x squared plus y squared 8 x 10 Y - 7 equal to zero and is concentric with the circle 2 X square 2 Y squared minus 8 x minus 12 minus 9 equal to zero
