Write the standard form of the equation and the general form of the equation of the circle with radius r and center (h, k) . Then graph the circle . r = 1 ; (h, k) = (0, - 1)

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.
