Product rule,2. y= 5x^2 sqrt (x+1) find dx/dy
---> By chain rule,6.
Find the slope of the tangent to the curve of y = ln (25x + 3) at x = 2.
You need to "complete-the-square".8.Find the center and radius of the circle: x2 + y2 - 18y = -17
Center = (9,0), r = - 8
Center = (1,8), r = 9
Center = (8,1), r =9
Center = (0,9), r = 8
