For a quadratic equation ax^2 + bx + c = 0, the discriminant is given by b^2 - 4ac
Thus for a^2 - 2a + 5 = 0,
a = 1, b = -2 and c = 5
b^2 - 4ac = (-2)^2 - 4(1)(5) = 4 - 20 = -16
A quarter resembles a 3D figure of a cylinder. The face is the area of the base of the cylinder and the space it occupies is the volume of the cylinder. We need to find out the height of the cylinder.
Volume = Area of base•height
Volume/Area of base=height
0.60/4.64=0.12931
Round to the nearest hundred
height=0.13 cm
