A block has mass 850 g (to the nearest 10 g) and volume 5 cm³ (to the nearest cm³). Work out the upper bound of its density, to 2 decimal places.A block has mass 850 g (to the nearest 10 g) and volume 5 cm^3 (to the nearest cm^3). Work out the upper bound of its density, to 2 decimal places.

Work out the coordinates of the turning point of y = x² - 4x - 7.Work out the coordinates of the turning point of y = x^2 - 4x - 7.

y is directly proportional to √x. When x = 25, y = 40. Work out y when x = 36.y is directly proportional to sqrt(x). When x = 25, y = 40. Work out y when x = 36.
